Smaller PCBs, including rigid-flex circuits, call for die attach using one of three methodologies, depending on the application.
Technologies that for years were the sole domain of semiconductor manufacturing have now migrated into today’s printed circuit board (PCB) manufacturing processes and flows.
These are not the old, traditional PCBs that we’ve grown up with; instead, they are a new breed of circuit boards that are largely small rigid and flex circuits or a combination of the two called rigid-flex. A growing wave of small electronics products like wearables, portable gear, and IoT devices are based on these newer, miniature circuit boards.
