Ordinary PCBs struggle to withstand high currents in high-temperature environments, while heavy copper PCBs significantly improve power density and reliability. However, when choosing heavy copper PCBs, the manufacturer's experience is more important than technical parameters\u2014reputable manufacturers will proactively remind you of etching process details and even provide resin formulation samples for comparison. This article shares, through a practical case, how to avoid delamination, side etching, and other problems by using a professional manufacturer..."}
