In the electronics manufacturing world, the terms PCB Fabrication and PCB Assembly (PCBA) are often used interchangeably, but they represent two distinct and critical phases. Fabrication is the birth of the bare board, while Assembly is where that board comes to life with components. This guide clarifies these differences and explains how a unified PCB design strategy can streamline the transition from a raw substrate to a high-performance functional device.
