The printed circuit board assembly, or PCBA, is at the heart of every electronic product. From smartphones to industrial controllers, the performance and reliability of electronic systems depend heavily on the quality of the PCBA. Among all the design elements on a board, one critical feature that often goes unnoticed by non-engineers is the GND, or ground connection. This article explores the fundamentals of printed circuit board assembly and explains why GND is essential for both signal integrity and electrical safety. What is Printed Circuit Board Assembly (PCBA)? Printed circuit board assembly refers to the process of mounting and soldering…
