Automotive PCBs are used in electric vehicles and traditional vehicles, including HDI PCBs, flexible PCBs, IC load boards, metal-core PCBs, high-frequency PCBs, single/double-sided PCBs, and multilayer PCBs. An electric vehicle takes PCBs with a total size of about 5㎡ to 8㎡, whereas a traditional vehicle with moderate levels of electrification takes PCBs of 1㎡ to 2㎡. Partnering with a reliable automotive PCB manufacturer is crucial for automotive electronics manufacturing. This article lists the top 10 automotive PCB manufacturers around the world, and we also showcase the automotive PCBs used for BMS, CCS, navigation, and LED lights.
1. Chin Poon Industrial
The Chin-Poon Industrial Co., Ltd. was founded in 1979 in Taiwan. It is a giant in automotive PCBs and often ranks as the world's largest automotive PCB supplier by volume.
Chin Poon specializes in conventional rigid PCBs, HDI, and heavy-copper PCBs. Their automotive PCBs are used for engine control units (ECUs), lighting, and infotainment.
Their long-term focus on the automotive sector has given them a massive, stable supply chain. However, Chin Poon Industrial provides only the bare automotive PCB fabrication without assembly.
2. TTM Technologies
TTM Technologies, Inc. was founded in 1998 and is headquartered in the United States. They are a leading global provider of technology-forward PCB solutions with a significant presence in the Western market.
TTM specializes in RF (Radio Frequency) and microwave PCBs, as well as heavy copper boards. It is an important automotive PCB supplier for radar, LiDAR, and safety-critical systems.
TTM provides both automotive PCB fabrication and assembly for complex automotive electronic systems. However, as a giant PCB manufacturer, TTM only serves leading companies at high volumes.
3. PCBONLINE
PCBONLINE was founded in 2005 in China. It is a turnkey PCBA manufacturer for both large-scale automotive companies and startups. Both Fortune 500 terminal companies and research institutes can benefit from our one-stop services, including automotive PCB prototype, PCB fabrication, component sourcing, PCB assembly, conformal coating, waterproof encapsulation, burn-in aging, IC programming, testing, enclosure, box-build assembly, and shipping.
PCBONLINE provides automotive PCBs for BMS, CCS (cell connect system), GPS navigation, wireless communication control, LED lights, and the entertainment system. Our automotive PCB manufacturing and assembly cover multilayer PCBs, high-frequency PCBs, flexible PCBs, rigid-flex PCBs, copper-core PCBs, transparent PCBs, and HDI PCBs.
Our engineering team provides one-on-one engineering support with precision and specializes in thermal management and impedance control. We do not have a minimum quantity limit for orders, and you can have turnkey automotive PCB manufacturing and assembly from PCBONLINE with high quality and cost-effectiveness.
4. Tripod Technology
Tripod Technology Corporation was founded in 1998 in Taiwan. It is a world-class leader known for its high-volume production efficiency and advanced manufacturing scale.
Tripod specializes in High-Density Interconnect (HDI) and multilayer PCBs. They serve automotive products primarily used in memory modules, telecommunications boards, and vehicle-mounted display panels.
Like Chin Poon, Tripod focuses heavily on large-scale bare board fabrication and generally does not provide full-scale electronic assembly services for the automotive sector.
5. Shennan Circuits
Shennan Circuits Co., Ltd. was founded in 1984 in China. As a key player in the high-end market, they bring aerospace-level quality standards to the automotive electronics industry.
Shennan specializes in high-speed multilayer PCBs and IC substrates. Their automotive applications focus on 5G-connected car technology and advanced telematics.
Shennan is a vertically integrated supplier that provides both high-end PCB fabrication and dedicated PCB assembly (PCBA) services to ensure seamless quality control.
6. Meiko Electronics
Meiko Electronics Co., Ltd. was established in 1975 in Japan. They are a specialist in thermal management.
Meiko specializes in Any-layer HDI and high-heat dissipation boards, such as aluminum PCBs used for electric vehicle (EV) power converters and LED lighting.
Meiko offers both bare PCB fabrication and full PCB assembly through its Electronic Manufacturing Services (EMS) division. However, the same to TTM, Meiko only serves giant companies at large volumes.
7. Unimicron
Unimicron Technology Corp. was established in 1990 in Taiwan. It is consistently ranked as one of the top PCB and IC substrate manufacturers globally, with a strong emphasis on high-end technology.
Unimicron specializes in Advanced HDI, IC substrates, and Rigid-Flex PCBs. In the automotive world, their automotive PCBs are critical for autonomous driving chips (ADAS) and high-speed communication systems.
While they are a fabrication giant, Unimicron does offer limited assembly services through specialized subsidiaries, particularly for complex integrated modules.
8. Nippon Mektron
Nippon Mektron, Ltd. was founded in 1969 in Japan and operates globally under the brand Mektec. They are the undisputed world leader in flexible printed circuitry.
Mektec specializes in flexible printed circuits (FPC) and rigid-flex PCBs. Their automotive PCBs are used for battery sensing lines in EVs and complex wiring in compact automotive interiors.
Mektec doesn't provide rigid PCB assembly but provides flexible PCB assembly, mounting components onto their flexible boards before shipping them to customers.
9. Kinwong Electronic
Kinwong Electronic was founded in 1993 in China. It is one of the fastest-growing PCB manufacturers worldwide, recognized for its diverse product portfolio and comprehensive one-stop PCBA service model.
Kinwong specializes in metal-core PCBs, rigid-flex, and HDI PCBs. Their automotive PCBs are widely used in battery management systems (BMS) and vehicle lighting.
While their primary strength is massive bare board fabrication, Kinwong has expanded to offer integrated assembly services, providing customers with a complete electronic solution.
10. AT&S
AT&S (Austria Technologie & Systemtechnik AG) was founded in 1987 in Austria. It is Europe's largest PCB manufacturer and a global pioneer in high-tech miniaturization.
AT&S specializes in high-end HDI and Embedded Component Packaging (ECP). Their automotive boards are often found in advanced powertrain systems and driver-assistance sensors.
AT&S doesn't provide automotive PCB assembly, but their ECP® technology allows them to embed active and passive components inside the PCB during fabrication. It is part of some electronics assembly in a sophisticated and integrated form.
