Manufacturing method for single chip COB USB devices with optional embedded LED

摘要

According to certain embodiments of the invention, a single chip COB USB manufacturing is using chip-on-board (COB) processes on a PCB panel with multiple individual USB PCB substrates. This single chip COB USB is laid out in an array of N×M matrixes. The advantages of this method are: 1) use molding over PCBA, versus conventional of using SMT process to mount all necessary component on substrate to form PCBA; 2) simpler rectangular structure to fit any external decorative shell package for added value; and 3) package is moisture resistance if not water proof.
