PCBA refers to a process, both a PCB board through the SMT chip, and then through the DIP plug-in the entire manufacturing process, PCBA from the Printed Circuit Board + Assembly referred to.
Differences between PCBA and PCB:
From the above description will know, PCBA refers to a processing process, can also be understood as a circuit board for the realization of a specific function of the circuit board, PCB circuit board will be completed after all the processes can be considered PCBA The The PCB is the circuit board, there is no electronic components, can not achieve any function.
With the high speed of electronic equipment, ultra-miniaturization, packaging technology has developed by leaps and bounds. Chip Size Package CSP and BGA packages are moving towards multi-lead and narrow lead spacing, and the bare chip package is also available. As a result of these advances in packaging technology, printed circuit board PCB also made new demands, that is, to adapt to high-density packaging and high-speed needs.
