PCBA is the finished circuit board, and FPCA is the soldering or assembly of FPC components. FPC is the abbreviation of FLEXIBLE PRINTED CIRCUIT, and its full name is flexible printed circuit board.
PCBA is the abbreviation of Printed Circuit Board + Assembly in English, which means that the entire process of the PCB blank board passing through SMT upper parts or DIP plug-ins is referred to as PCBA.
FPCA is the abbreviation of Flexible Printed Circuit Assembly, which means FPC component soldering or assembly.
The difference between PCBA and FPCA is mainly the difference in board materials:
FPCA is assembled using flexible circuit boards. The boards are bendable and can be used in relatively high-end products such as mobile phones. The density is high, and the processing is difficult and the production cost is high.
PCBA is assembled using rigid circuit boards, which is what we usually call circuit boards. It has a wide range of applications. The circuit board assembly technology is mature, the process difficulty is smaller than that of FPC, and the manufacturing cost is low.
