Printed circuit boards (PCB) used in automobiles, mainly in cars is in a boom phase with high reliability and longevity being the main coefficient of competition.
As user patterns are changing with innovations in the way people drive, automotive safety systems are moving towards Metal Core PCBs known as MPCB.
Anti-lock brake systems, advanced safety features, ECU systems that control engines and GPS navigation systems are all seeking high quality PCBs.
The demand for PCBs in automobile will be up as vehicle owners keep adding accessories, including televisions.
According to Market research, Global automotive PCB market is now in the size of US$5.28 billion and is the fastest-growing sub segment in PCB industry. The momentum is expected to sustain until 2019.
In automotive PCBs, field applications abound in Engine Control Unit, Starter, Alternator, Transmission Control, Fuel Injection, and Power Steering.
However, the market is not an easy one. It is highly quality conscious and automotive PCBs to have high on reliability with as there is a high recall system and rejection rate making many makers losing contracts in the name of faulty products.
An example is PCBs used in automotive engines and gearbox where high temperature above 150 is common place. There the PCBs used have ceramic multi-layer substrate containing alumina and aluminum nitride.
Top suppliers are offering PCBs to European and US carmakers including Germany’s Schweizer, Duwel, Wurth, CMK and Meiko.
Another growing niche PCB market is that of HDIs. As mobile computing and remote working have expanded, the demand for faster computers has surged. That is where HDI Technology is making ripples with more functionality, low weight and smaller size.
Defined as High Density Interconnect, HDI PCBs are used in places with higher wiring density per unit area and as different from conventional PCB.
HDI boards have blind and buried microvias of .006 or less in diameter. Thanks to HDI technology, more components can be placed on both sides of the raw PCB. The highlights are finer lines, smaller vias and higher connection pad density than offered by conventional PCB technology.
Among the advantages offered by HDI PCB are smaller size, high speed and high frequency. It is the main component in most personal computers, portable computers, mobile phones and personal digital assistants. The underlying merit is that HDI PCB with its reduced size and weight can deliver enhanced electrical performance.
