What is PCB?

PCB is the abbreviation of the china printed circuit board. PCB composed by insulated baseboard, pads for electronic components and copper foil connecting wires. PCB can replace complex wiring to achieve circuit connection between components in the circuit.

pcb boards china is the motherboard of electronic components. Before the advent of PCB, the interconnection between electronic components was done directly by wires. Today, PCB has been widely used in the electronics industry, due to the PCB tecnology, manual wiring errors can be avoided, and electronic components can be automatically DIP or SMT, automatic soldering, and automatic detection, ensuring the quality of electronic device and improving labor productivity, reduce costs as well.

What Is the Difference Between PCB And PCBA?

PCB is a blank circuit board without any electronic components soldered on. It just composed by baseboard with pads and copper foil connection wires.

PCBA is a complete assembled board with electronic components. We apply surface mount technology and through-hole soldering technology solder the components onto the board. The components are soldered to the board can be SMD, through hole, UBGA, QFN, POP, leadless chips, connectors and terminals.
