The multiple advantages of the Mulpin Electronic component and Printed Circuit board (PCB) system will have a vast impact on the Aerospace Industry. If you the reader are not yet familiar with what The Mulpin system is, it is recommend that you start by reading the section What is Mulpin? on our home page under the About Us tab.

The photograph above shows a typical avionics Printed Circuit Board or PCB. Although used in the Space Shuttle, it is typical of any PCB in which the components are all mounted on the PCB surface. If this PCB were to be built using the Mulpin system, all of these components would be invisible as they would lie beneath the surface of the PCB.

The Aerospace industry is in for a great deal of change in the near and long term future. As an increase in activity in this area opens up, a whole new range of opportunities as well as challenges will need to be met.

In the last few years it has become possible to plan for and to operate exciting and profitable businesses such as designing and constructing new vehicles for Space Tourism and for trips to other planets. Costs are bound to come down as innovative new ideas are brought to the fore. We at Mulpin are innovators for the Electronics industry, and can help the Aerospace industry in a number of ways.

We have developed a new very rugged light weight and reliable Electronic component and Printed Circuit board (PCB) system with many unique new properties which we call the Mulpin system. Some of the advantages which will assist the innovation of the Aerospace industry are listed below.

  • Extremely rugged PCBs which are immune to even severe vibration and thus require a lighter frame to support them.
  • The unique system used by Mulpin allows for components to reduce in size by more than half, whilst improving the heat removal from them. This is not possible with currently produced components.
  • Reduced weight due to the reduced housing requirements, smaller components and thus smaller PCBs, and the reduced need for heat sinks.
  • No external shielding (against EMI/ EMP) required, which reduces weight even further.
  • Mulpin PCBs use a US patented unique system of burying components within the PCB, which gives the Mulpin System its extreme ruggedness.
  • Mulpin PCBs can dissipate more of the internally generated heat, thus avoiding external heat sinks in many cases.
  • Heat sinks can be applied when needed without compromising any of Mulpin’s properties. This is not possible with currently produced systems.
  • Mulpin components are all self screening against all forms of electromagnetic radiation, and especially EMP. Very small components are no more susceptible than larger ones.
  • Mulpin PCBs are shock proof, dust proof, and can easily be made water proof and corrosion proof.
  • Extended PCB life (reliability) due to lower temperature extremes during warm up and cooling down cycles.
  • Cost reduction due to the fact that there is less hardware required to support the Mulpin PCBs. The production cost for Mulpin parts and PCBs is likely to be on a par, with the actual PCB cost being lower due to less surface area requires for a given circuit.

These and other advantages of the Mulpin system will ensure its use in the future Aerospace industry.

Aviation

Avionics PCB from the Space Shuttle

Introduction

The multiple advantages of the Mulpin Electronic component and Printed Circuit board (PCB) system will have a vast impact on the Aviation Industry. If you the reader are not yet familiar with what The Mulpin system is, may I recommend that you start by reading the section What is Mulpin? on our home page under the About Us tab.

The photograph above shows a typical avionics Printed Circuit Board or PCB. Although used in the Space Shuttle, it is typical of any PCB in which the components are all mounted on the PCB surface. If this PCB were to be built using the Mulpin system, all of the component would be invisible as they would lie beneath the surface of the PCB. All of the components would allow their heat to escape to the air more easily and severe vibration would not allow the components to work loose due to inertia. Mulpin Research Laboratories have further information on how all of this is achieved by sending an email to info@mulpin.com

The Mulpin system is also by its nature dust and moisture proof. If its connectors are of a water proof type, then the entire PCB will also be water proof. This would be an advantage where air craft are used in rescue from the sea, as corrosion is a problem faced by today’s avionics in that situation. It would be a simple matter to make Mulpin systems corrosion proof as well.

Another problem faced by the industry is the possibility that air craft may be harmed mid flight in the event of an EMP attack by a foreign power, or by EMP which has come from the sun. However unlikely this may seem it remains a possibility. Such an attack may render the electronic instruments of the air craft inoperative, causing a forced landing or worse, a crash. Since a Mulpin system is comparable in price to a conventional one, it makes good sense to build all new air craft using Mulpin technology.

Mulpin Research Laboratories are developing air craft and other instruments which will still function perfectly both during and after an EMP attack.

Domestic Electronics

Mulpin in the Domestic Market

The Domestic market for electronics is vast, and Mulpin will help to reduce and ultimately eliminate problems, which are difficult to solve with current technology. As electronic equipment gets smaller; the heat generated within becomes more difficult to remove so that the equipment can operate safely for long periods of time. The increasing speed and capacity of computer memory compounds the situation as even more components must fit into even less space.

Another problem faced by both the electronics industry and the end user is as electronics gets faster, it also radiates more high frequency noise which manifests itself as EMI or Electro Magnetic Interference to other services. This problem is compounded by the large numbers of units made for the domestic market. Manufacturing new equipment with Mulpin Technology will eliminate both of these problems simultaneously, saving money and time. Protecting the manufacturers brand name is also a major consideration, as there will be fewer warranty repairs as equipment reliability is improved by using Mulpin. As equipment gets more complex, new tighter rules to combat EMI are likely to emerge. Mulpin will make these targets much easier and more economical to meet. It is likely that Mulpin will set new bench marks for all manufacturers, thus making it necessary for all of them to use Mulpin to meet new specifications economically.

Mulpin will help

It has been demonstrated both here at Mulpin Research Laboratories, and again at Scitech (Science Centre in Perth, Western Australia) that using the Mulpin principle and components for the manufacture of electronic goods can eliminate this noise pollution from getting out into the environment. Please see Mulpin Test Results under the Intellectual Property tab on this web site for detailed test results. There are now many electronic devices that are common to both the commercial and domestic worlds. These include printers, faxes, modems, and computers. Every one of these items can cause harmful interference to radio services. Most homes now have all of these devices and others such as game consoles.

Currently there are compromise limits on the level of EMI permitted on any device. However this does not eliminate the problem, and it will only get worse if nothing is done to improve the situation.

It is time to look at Mulpin in the production of domestic electronics right now, because even after its introduction, it is likely that current equipment will still be operating for about a decade before being retired due to obsolescence.

At the time of writing, Mulpin is developing new technology aimed at reducing the cost of domestic equipment, whilst improving its performance and reliability.

The Military

Mulpin In The Military

Introduction

The huge advantages of the Mulpin Electronic component and Printed Circuit board (PCB) system are likely to be felt first by the Military. If you the reader are not yet familiar with what The Mulpin system is, may I recommend that you start by reading the section “What is Mulpin” on the “About Us” menu.

Specific uses

Several challenges with military design exist and some of these are shown below. These can all be improved by using Mulpin parts.

Embedded Passives: - These will be replaced with Mulpin parts. Mulpin parts are likely but not always buried. However the unique way that this is done will make embedded passives much easier to achieve. More information can be found by contacting info@mulpin.com

Thermal Management: - This is greatly assisted with Mulpin parts, because of their connection directly to the ground plane PCB layer. Mulpin components can do this without RFI or EMP compromise. See our Mulpin Test Results under Intellectual Property heading on this site.

RFI /EMI/EMP suppression: - This will be vastly improved with Mulpin parts because they are self shielding, thus avoiding external shielding with its incumbent extra weight. See our prototype test results under Intellectual Property heading on this site.

Complex RF power divider networks: - These will be greatly assisted with Mulpin in at least two ways. Better heat dissipation will mean that a simpler circuit with fewer resistors will be needed. Complete RF shielding will ensure minimal escape of undesired RF energy. Currently these divider networks use buried resistors, and these will be done away with when Mulpin is used. Further information can be gained by contacting info@mulpin.com

Circuit isolation using via fencing: - This is a common way to minimize unwanted RF coupling between circuits. Combining this technique with individual components screened with the Mulpin technique will improve the prospect of minimizing the unwanted coupling between stages of a circuit. This was the original reason for the invention of the Mulpin Concept. There are other patents we have in development which will enable via fencing to be replaced with Mulpin technology. This will virtually eliminate the radiation which seeps past the via fencing. This will also improve the EMP performance of the circuit. For more information please contact us at info@mulpin.com

Fine Pitch BGA implementations: - One of the advantages of Mulpin is the ability to have many more pins in a given area without the need for increased accuracy required for the Fine pitch BGA parts. It is possible that Mulpin and BGA technology could be combined with BGA for this purpose. The added advantage of better heat transfer will make the reliability of BGA/ Mulpin parts improve due to the reduction of the heating and cooling expansion and contraction problems these parts face. For more information please contact info@mulpin.com

Soldier

Advanced protection:- A foot soldier must carry his or her provisions, and these days hi tech equipment in order to complete a successful mission. It is important that this equipment be as light and as rugged as is possible to eliminate fatigue in both the equipment and the soldier. These requirements are often a compromise, as ruggedness also means heavy. A soldier carrying electronic equipment based on the Mulpin system will have a large weight advantage and a reduced electronic signature, over a soldier who has conventional equipment. Mulpin does not need as much weight in its enclosure or chassis due to its inherent ruggedness and vibration resistance. A Mulpin system is by nature dust proof and when water proof connectors are used will easily be rendered water proof and this also without adding weight. This may save the life of that soldier and that of those depending on him or her in the event of the equipment being submerged.

Mobility

Low Observable and Counter Low Observable technologies:- Equipment built using Mulpin Technology will make low observability much easier to achieve and with less design time. Mulpin will leave either no footprint of itself (electronic) or very little. This is due to Mulpin’s unique self shielding component and PCB structure.

Decrease weight by 70%:- Mulpin Electronics will require no or very little external shielding which takes up weight and space in current systems, so that when Mulpin parts and systems become available, considerable weight reduction should result, assisting in achieving this goal.

Decrease Size by 50%:- Mulpin’s unique structure allows more pins for a given integrated circuit footprint, thus enabling the size to be reduced. The improved heat dissipation of Mulpin will also allow the size to be reduced. When Mulpin parts and systems become available, considerable size reduction should result, assisting in achieving this goal.

Power and Energy

Signature reduction:- Switch mode Power units generate a large amount of EMR which can be detected remotely. This could largely be avoided with the use of Mulpin Technology., because of its unique buried self shielding structure.

Power systems technologies:- These could be built smaller, lighter and more rugged due to the Mulpin structure which could also be made entirely water proof quite simply.

Intelligence, Surveillance and Reconnaissance (ISR)

  • Advanced unmanned systems:- could be improved with the use of Mulpin with its proven ability to withstand EMP attacks. The inherent vibration, dust and water resistant nature of Mulpin will also aid in both reliability and weight reduction of these systems.

Cyberspace Operations (Attack, Defend, Exploit)

Information assurance:- The Mulpin structure in addition to its ability to withstand an EMP event, has an added advantage that it is or can be very difficult or impossible to read data from, if it is captured. Data would not be wiped during an EMP attack.

Printed Electronics, Energetics, Materials and Sensors (PEEMS)

Applying electronics and biotech philosophies to energetics and munitions systems that are:

  • Smaller:- The Mulpin structure allows more pins for a given footprint area of a component which means that the component can be smaller and thus the equipment also can be reduced in size.
  • Lower cost:- Military equipment will benefit greatly in this area as there is less time required to make a product have a MIL spec performance.
  • Higher reliability:- Reliability is one of the Mulpin characteristics as it can be completely buried and thus immune from all external influences. Heat sinks can be added where needed without compromising any of the other performance characteristics.

Printed Electronics

  • Long-Term aging:- The lower expansion and contraction of Mulpin circuits due to lower temperature variation will ensure longer life. This could also include precision clock circuits where temperature extremes may affect ageing.

Information Technology: Command, Control, communication and computers

  • High Bandwidth Technologies:- Mulpin parts can be made electrically and physically balanced with extremely low inductance, making them ideal for very fast amplifiers etc. It is possible to build physically balanced circuits which it is currently not possible to build. This can increase speed and reduce unwanted emissions (harmonics).
  • Advanced Multi-function Software Defined radios:- Software defined Radios (SDR) have digital signal processing built in. It is difficult to stop unwanted emissions from the circuits. This can interfere with the antenna circuit of the receiver, making these hard to design. Mulpin was initially invented to solve problems like this. It’s buried and self shielding properties make Mulpin ideal for designing SDR.

Additionally:- Mulpin is currently developing a very high level, high performance mixer which will have a third order intercept of +45dBm and a Noise Figure of 6dB. The mixer is being designed with SDR as its primary use. More information from info@mulpin.com

Automotive

The electronics content of motor vehicle accounts for 40% of vehicle value (Source from: N.T. Information Ltd) and the PCB automotive industry hit USD$25 billion in 2010. Vehicles now use PCBs for: Equipment Panel Controller, Radio, Automatic Transmission, SRS (air bags), ABS (brakes) Auto Cruise Sensor, Power Steering, Engine Controller and many other components.

If you the reader are not yet familiar with what The Mulpin system is, it is recommended that you start by reading the section What is Mulpin? on the About Us tab.

The automotive industry can be a very large user of the Mulpin System. Automobiles create a very harsh environment on their electronic systems. Mulpin Technology will be of particular importance to the reliability of future motor vehicles. As more and more systems are being developed for this industry, the Mulpin System could be used to improve reliability in the following areas.

  • Engine management processors. Keep out dust, oil, exhaust gas contamination, and RFI both in and out.
  • Ignition circuits. Keep out dust, oil, exhaust gas contamination and RFI and improve heat sinking simultaneously.
  • Engine management sensors. These could be developed such that the bare minimum of the sensor area is exposed to the engine environment.
  • Power relays for equipment like head lights, horn, break lights and turning indicators. The buried nature of the Mulpin system will ensure ultimate reliability and ruggedness.
  • New gas discharge lighting system power supplies. Keep out dust, oil, exhaust gas contamination, and RFI both in and out. Heat sinking is done without compromising the other advantages.
  • Fuel injection systems. Keep out dust, oil, exhaust gas contamination, and RFI both in and out. Heat sinking is done without compromising the other advantages.
  • GPS in car Navigation systems. These systems when built in would likely outlast the vehicle in which they are installed. Maintenance is unlikely to ever be needed.
  • Wind screen wiper control. Keep out dust, oil, exhaust gas contamination, and RFI both in and out.
  • Air bag control. Keep out dust, oil, exhaust gas contamination, and RFI both in and out.
  • Seat positioning motor control. High reliability, can be hidden away for maintenance is likely not needed.
  • Car audio equipment, including power amplifiers with or without heat sinks. Already extremely reliable. Mulpin would make this reliability easier to achieve.
  • Air conditioning Control systems. Keep out dust, oil, exhaust gas contamination, and RFI both in and out.
  • Other in car entertainment such as DVD players. The buried nature of Mulpin will enhance the ruggedness of such equipment, requiring less warranty work and thus lower overall cost to the manufacturer.

Electric Vehicles

Electric Vehicles deserve a special mention here because almost the entire industry and its infrastructure has yet to be completed and standardised where required. This is an ideal time to include Mulpin systems and sub systems where these become the optimum solution. Electric vehicles are likely to be subject to many of the same environmental issues as are their fossil fuelled cousins. Temperature issues will relax but there will be many similar issues such as accumulated dirt, and additional issues such as dissipating the heat from motor drive circuits etc.

Mulpin will be of a tremendous benefit to the Electric car industry. It is beneficial to mention a few of these here.

  • Vehicle maintenance. There may be times when a complex motor control PCB needs to be changed. When these are designed with the Mulpin System, the PCB can be simply detached from its heat sink, since the PCB surface is flat. The heat sink would remain in situ.

The entire engine and control system can be cleaned with a simple jet of water because of the self sealing nature of Mulpin circuits.

If a vehicle were to be immersed in water such as when travelling over a flooded road, it is likely to remain in operation. Cleaning up the aftermath on the electronics will be a very simple matter when compared to doing so on conventional electronic circuits.

  • Electrical noise pollution. Electric vehicles if properly designed should not emit any electrical noise, which can be detected by its own radio receiver or by other nearby receivers. This is a real problem with the ignition systems of many petrol engines. If an electric vehicle is designed from the ground up with Mulpin systems, electrical noise emissions will be minimal. Mulpin could set the standard by which all manufacturers must abide. With Mulpin systems, much of the emitted radiation remains within the circuit where it is generated, due to the excellent self screening nature of Mulpin Systems and components. Extensive testing has been done in this area and the test results can be viewed from the home page by clicking on Intellectual Property and then on Mulpin Test Results.

Medical

Typical Medical Pacemaker

Introduction

The huge advantages of the Mulpin Electronic component and Printed Circuit board (PCB) will be indispensable within the Medical Industry. If you the reader is not yet familiar with what The Mulpin system is, may I recommend that you start by reading the section “What is Mulpin” on the About Us menu.

The Medical Industry uses a multitude of electronic devices, many used in no other industry. One of the most important things with medical electronics is extreme reliability, especially where human life is dependent on the equipment.

A pace maker is an example where very high reliability is required. A pace maker when built with the Mulpin System will be smaller due to the reduced size of its semiconductors and other parts. Long term reliability is important and, with the introduction of new models there is always the necessity to ensure that this continues with every other improvement. A Mulpin system can be of assistance in this area as it is by its very nature, reliable.

Hospitals have many areas where interference from outside sources can be a problem and this can be dangerous. This is the reason why mobile telephones should be turned off within a hospital. It cannot be assumed that all mobile telephones are indeed turned off at any particular time.

Much equipment is sensitive to the microwave signal generated by mobile telephones as it is difficult to keep the signal out from the circuits of standard circuits used in electronic equipment, including medical electronics. Mulpin Circuits have the inbuilt ability to keep these signals out of the circuit entirely. This occurs naturally because of the structure of Mulpin circuits. Mulpin Research Laboratories have done extensive and even extreme testing to ensure that Mulpin circuits can keep all unwanted interference out. These test results can be viewed from the home page by clicking on Intellectual Property and then on Mulpin Test Results.

Mulpin systems can easily be designed to withstand accidents such as spillages and jarring. This is because Mulpin circuits are embedded entirely within a Printed Circuit Board making them immune to most of the things which can cause damage to standard circuits. The cost of producing a Mulpin system is comparable to that of a conventional system, but has far better safety and reliability built in by its very nature. Mulpin can save lives.

Communication

Mulpin in the Radio and Telecommunications Industry, including Military, Civilian, and Mobile telephony.

Introduction

The multiple advantages of the Mulpin Electronic component and Printed Circuit board (PCB) system will have important advantages in the Radio and telecommunications industries. If you the reader are not yet familiar with what The Mulpin system is, it is recommend that you start by reading the section ‘What is Mulpin’? shown on our home page under the ‘About Us’ tab.

Radio Communication and Telecommunications together share special problems associated with electromagnetic interference (EMI). One source of such a problem manifests itself as undesirable received (and transmitted) signals at the frequency being received or transmitted, thus making the equipment less useful to its operator. Such signals may come from one or more on board sources described below. These signals can be distinguishable from a wanted signal coming from the antenna. Nearly all radio equipment suffers from this malady to some degree.

This problem can be extremely difficult to solve because the internal interfering signals are several million times stronger than the signal at the antenna terminal of the equipment. A good equipment designer will endeavor to minimize the number of channels or frequencies which suffer the problem, and take steps to attempt to screen these signals to keep them away from the antenna. This all costs money and adds weight to the equipment, and may in some cases have design compromises to meet the equipment specifications.

Mobile Phones

Mobile phones are having more processing power than ever before and it is constantly increasing, more rapidly than any other communications sector, putting more ressure on saving PCB space and eliminating undesirable signals as for any other radio system of modern design. Mulpin components could more than double the component density currently used without adding difficulties in the assembly process.

Sources of interference

  • Class D Audio Power Amplifiers: These are a relatively recent addition to radio equipment and have the advantage of high efficiency, and are thus very beneficial when the equipment is battery operated. However they produce large amounts of interference which is often not stable in frequency, interfering with a wanted signal periodically.
  • Microprocessors: These are devices which also generate interfering signals, but are usually of a more stable nature causing either bursts of interference (data) or continuous interference from a reference clock signal.
  • Switch Mode Power Supplies: These too have found their way into radio communication equipment, also because of their superior efficiency. Unfortunately these too cause larger amounts of interference similar in nature to that from Class D amplifiers mentioned above.

Mulpin to the rescue

Mulpin Components are self screening, and the components which generate the required above mentioned strong signals can within themselves be screened and the signals which would otherwise be radiated (induced) into the antenna of the equipment are directed to the inside of the PCB where they are trapped and cannot escape. If each and every component were to have the Mulpin Format, then there would be no signal escaping to the antenna. If equipment is well designed, Mulpin can prevent or greatly reduce both radiated and conducted spurious emissions.

This explanation is somewhat simplified, but it is sufficient to show how differently a piece of radio or other telecommunications equipment will perform when Mulpin components are used. Note that a reduction in external screening will be needed to achieve the required end. The components, being each screened individually will make external screening un-necessary. It is beyond the scope of this article to describe further, but it is possible to screen circuits in such a way as to have been until now, impossible, thus bringing further simplification and improvement to designs. See the test results of Mulpin prototypes under “Mulpin Test Results” under the Intellectual Property heading on the Home page.

Satellite

Satellites have many differing and sometimes contradictory requirements. For instance, a satellite needs to have as little mass as possible, and also have protection from solar radiation and solar wind. These are conflicting requirements because the shielding from solar radiation add weight to the satellite.

Satellites need also to be as rugged as possible so that they will still be operable after the vibration received on the spacecraft before orbit is reached. This also is in conflict with keeping the weight down.

A New Solution

We at Mulpin Research Laboratories have developed a new very rugged light weight and reliable Electronic component and Printed Circuit board (PCB) system with many unique new properties which we call the Mulpin system. Some of the advantages which will assist the innovation of the satellite industry are listed below.

  • Mulpin PCBs use a unique US patented system of embedding components within the PCB, through an opening in the outer layers of the PCB. This gives the Mulpin System its extreme ruggedness and protection of components.
  • Extremely rugged PCBs which are immune to even severe vibration and thus require a lighter frame to support them.
  • The unique system used by Mulpin allows for components to reduce in size by more than half, whilst improving the heat removal from them. This is not possible with currently produced components.
  • Reduced weight due to the reduced housing requirements, smaller components and thus smaller PCBs, and the reduced need for heat sinks where the PCB itself is capable of dissipating the heat from components.
  • No external shielding (against EMI/ EMP) required, which reduces weight even further.
  • Mulpin PCBs can dissipate more of the internally generated heat, thus avoiding external heat sinks in many cases.
  • Heat sinks can be applied when needed without compromising any of Mulpin’s properties. In fact a single heat sink when needed can remove heat from all of the components on a PCB. This is not possible with currently produced systems.
  • Mulpin components are all self screening against all forms of electromagnetic radiation, and especially EMP. Very small components are no more susceptible than larger ones.
  • Mulpin PCBs are shock proof, dust proof, and can easily be made water proof and corrosion proof.
  • Extended PCB life (reliability) due to lower temperature extremes during warm up and cooling down cycles. There are new packages under development which will allow flip chips to be as large as desired without limitation, as die and solder joint cracking from the PCB are no longer a problem.
  • Cost reduction due to the fact that there is less hardware required to support the Mulpin PCBs. The production cost for Mulpin parts and PCBs is likely to be on a par, with the actual PCB material cost being lower due to less surface area requires for a given circuit.

These and other advantages of the Mulpin system will ensure its use in the future Aerospace industry.
