Technical Challenges for EV Charger PCBA Manufacturing
EV charger control PCBA works under AC high-voltage conditions, facing risks of high current, temperature rise and electromagnetic interference, which brings multiple manufacturing challenges. First, high-current tracks require sufficient copper thickness and optimized layout to avoid overheating during long-time charging. Second, isolation clearance and creepage distance must strictly follow safety standards to prevent high-voltage breakdown. Third, the soldering of large power relays and through-hole components needs stable solder joints to resist thermal cycling and vibration. Our engineering team conducts professional DFM manufacturability review at the early stage of each custom PCB assembly project, addressing these risks in advance to ensure the EV charger PCBA runs safely and stably for charging infrastructure.
