Open frame power supply circuit boards are bare power core boards without outer protective housings, designed to be embedded directly inside all kinds of finished equipment as built-in power sources. We provide flexible pcb fab and assembly and EMS contract service for open frame power pcba. Our high-density compact layout SMT assembly technology effectively saves internal space of finished products, and rigorous safety aging testing strengthens short-circuit protection performance, widely used in medical instruments, industrial control machines and smart display devices.
