Automotive PCB design

Automotive PCB design services cover rigid, rigid-flex, high-speed multilayer, HDI, heavy copper, and high-frequency PCB types, with precise impedance control, EMC optimization, and wide temperature adaptation to meet strict reliability, signal integrity, and heat dissipation requirements of all automotive electronics applications.

Overview

Automotive electronics have the strictest requirements for PCB reliability, signal transmission stability, environmental adaptability, and safety compliance compared with most industrial and consumer electronic scenarios. The rise of intelligent cockpits, advanced driver assistance systems (ADAS), autonomous driving, and new energy vehicle power systems has put forward higher demands for high-speed data transmission, high-power load carrying capacity, and anti-interference performance of on-board PCBs. Core pain points in automotive PCB design include signal attenuation and crosstalk in high-bandwidth sensor transmission, thermal failure of high-power power modules, unstable operation in wide temperature and high vibration environments, and non-compliance with automotive industry safety specifications. Systematic automotive PCB design services cover the full process from schematic optimization, stack architecture planning, component placement and routing adjustment, simulation verification, to prototyping and mass production process guidance, effectively solving the above industry pain points, and meeting the differentiated design needs of different automotive electronic application scenarios.

Quality Standards

Automotive PCB design follows unified industry standards and strict control processes to ensure that the final product meets the access requirements of the automotive electronics industry:

• Material selection follows IPC-A-600 and IPC-6012 automotive grade substrate specifications, all materials are RoHS and REACH compliant, adapt to lead-free reflow assembly processes, and meet the halogen-free requirements of most mainstream automotive manufacturers.
• Design processes strictly follow IPC-2221 general PCB design standards and IPC-2223 rigid-flex PCB design standards, integrate DFM (design for manufacturability), DFT (design for test) and DFA (design for assembly) checks in every design link, avoid manufacturability defects in the later production stage, and improve the mass production yield of products.
• For functional safety related automotive electronic products, the design process aligns with ISO 26262 functional safety requirements, supports design matching for ASIL A to ASIL D safety levels, and reduces the risk of functional failure during product operation.
• All design schemes are verified to meet the requirements of stable operation in the industrial grade temperature range of -40℃ to +85℃, resist 10~2000Hz vibration and 100G shock, and can be customized to meet different IP protection level requirements according to product installation positions.
