Holding electronics together under high voltages and temperatures

While EVs may have much in common with consumer electronics, the combination of high voltages and powers, and the safety-critical nature of many of their systems, is providing some major headaches for printed circuit board assembly (PCBA) contractors and electronics manufacturing services (EMS) providers – headaches that vehicle OEMs won’t be able to cure with […]
