In the vast market of PCBs, many segments operate as the end users. Among the top user industries are automotives, telecommunications, aeronautics, and electronics.
In terms of hyper growth, the major user segment is automotive industry, where high –end user PCB applications are surging phenomenally.
As the fastest-growing field in PCB industry, automotive PCB will be dominating the PCB industry until 2019. According to market research, Global automotive PCB market size is $4.96 billion with a growing rate of 6.5 percent and may touch $7 28 billion in 2017.
Within automotive PCBs, power trains take up the largest proportion at 32 percent in areas like Engine Control, Starter, Alternator, Transmission Control, Fuel Injection, and Power Steering.
Powertrain’s 50 percent of usage is followed by parts like body, lighting, HVAC, Power Door, Seat, Keyless, and TPMS.
Other areas of high use in automotive PCBs are LED lighting, Safety systems, consisting of ADAS, and Airbag. What the manufacturers have to take note is the high reliability of Metal Core PCBs.
Therefore, high recall system in the automobile industry is a rule and small players cannot take those risks. Challenges for automotive PCBs are high temperature and high frequency.
As for multilayer PCB, they find application in modern electronic systems. PCB layout planning is important as the electronic circuit itself in extracting the best performance in electrical, mechanical and thermal parameters.
Multi-layer PCBs maintain signal integrity and power integrity. But constraints of parasitic resistances, capacitance, and inductance hamper power and signal strengths. There are remedial measures to the PCB designs caused by excess traces of copper carrying finite resistance.
Controlled impedance traces are needed for better management of the circuit for high accuracy.
In PCB procurement, chances of mistakes are high in the matter of rightly assessing a supplier and his products. Obviously, there is a risk as big money is involved and the market expects good quality products. So, it is recommended to outsource the service of a PCB consultancy in minimizing the loss and waste of investment at the sourcing stage.
Many user industries are already taking the service of a PCB consultancy in managing the procurement right from initial concept to the finished product.
PCB design consultancies are working with major players in the aerospace, automotive, communication, defence, medical, security and rail industries. They usually outperform the expectations of the clients and improve the following areas:
• Reduced time to market
• Curbing unwanted prototypes
• Better PCB design
• Reduced manufacturing costs
