The printed circuit board (PCB) or a printed wiring board is an electronic board which physically supports and electronically connects various electronic components in almost all the electronics and computing devices. A PCB can be a single layer or be made by combining different sheets of non-conductive materials or substrate including fiberglass, plastic, or composite epoxy to hold a copper circuitry. Automotive PCBs are generally used to manage engine, radar, entertainment systems, GPS, digital displays, mirror controls, and power relays timing systems. The increasing focus on engine downsizing, electrification of automotive mechanism, emission regulations, connectivity, and safety are propelling the demand for these semiconductors in the global market. The growing application of semiconductors in hybrid and electric vehicles, advanced driver assistance systems (ADAS), infotainment systems, and telematics will fuel the growth of the market. The automotive PCB market is expected to reach values of over $13 billion by 2023, growing at a CAGR of more than 8% by 2017-2023.

The three different product types in the PCBs market are:

1.    Single-Side Automotive PCBs Market

A PCB’s basic formation is made for a copper plate that is then fabricated and laminated with materials and coatings. The single side automotive PCBs are most cost-effective, and they are easily designed and manufactured, hence making them the most commonly used PCBs in the automotive industry. These devices are ideal for simple electronics such as lighting systems, wiper systems, and electronic throttle modules among others. APAC is the highest producer of single side PCBs with China, Taiwan, and South Korea the largest producing countries. The single side PCBs market is the largest in terms of volume and is projected to grow at a CAGR of over 8% during 2018-2023.

2.    Multi-layer Automotive PCBs Market

Multi-layer automotive PCBs were introduced as the next evolution of PCB boards after the single or double-sided PCBs. They can be fabricated on ceramic, copper, and aluminum. Multi-layer PCBs are ideal for high-frequency and high-speed circuits; hence they are ideal for automotive electronics such as radar systems, ECU among others. Multi-layer PCBs are ideal for high speed, multi-functional, high capacity, and small size electronic components. As the automotive industry is moving towards lightweight materials and compact vehicle structure, multi-layer PCBs are witnessing increased adoption in the automotive industry. Leading PCB manufacturers are investing in exploring means to reduce the cost of production and cycle time by implementing new advanced manufacturing techniques and processes.

3.    Flexible Automotive PCBs Market

Flexible automotive PCBs are the most advanced technology in fabrication. It was first used in aerospace, and lately, they are preferred by automotive OEMs due to its lightweight properties and compact and flexible packaging benefits. The wide range of benefits offered by the flexible PCBs includes size and weight reduction, improved reliability and impedance control, stronger signal quality, more robust operating temperature range, higher circuit density, unparalleled design flexibility, elimination of mechanical connectors, reduced wiring errors, and freedom in packaging geometry. Such benefits will propel the growth of the flexible PCBs market.

The leading vendors in the automotive PCBs market are TTM Technologies, Chin Poon Industrial, Meiko Electronics, CMK Corporation, and KCE Electronics.
