What the heck is Circuit Card Assembly (CCA)?

When the board doesn’t have a built-in components it is more correctly known as a printed wiring board (PWB) or etched wiring board. However, the expression printed wiring board has grown into disuse. A PCB populated with electronic parts is recognized as a printed circuit assembly (PCA), printed circuit board assembly or perhaps PCB assembly (PCBA). The IPC favored term for assembled boards is circuit card assembly (CCA), and for assembled backplanes it is backplane assemblies. The term PCB is utilized informally for both blank and assembled boards.

What is printed circuit board (PCB)?

A PCB mechanically backs up and electrically joins electronic components employing conductive tracks, pads along with other features etched from copper sheets laminated onto a non-conductive substrate. Essential components – capacitors, resistors or active devices – are often embedded on the PCB. Complicated PCBs might have components inlayed in the substrate.

In reality, PCBs are generally single sided (one single copper layer), double sided (2 copper layers) or multi-layer (exterior and inner layers). Conductors on different layers are connected with vias. Multi-layer PCBs provide for much greater component denseness.

FR-4 glass epoxy is the major insulation substrate. A basic essence of the PCB is an FR-4 panel with a lean layer of copper foil laminated to one or both the sides. In multi-layer boards, a variety of layers of material are laminated together.

Printed circuit boards are used in just about the least complicated electronic devices. Alternatives to Printed circuit boards comprise of wire wrap and point-to-point construction. PCBs demand the further design endeavor to formulate the circuit, but manufacturing as well as assembly are usually automated. Fabricating circuits with PCBs is much less costly and faster than applying alternative wiring methods as components are usually attached and wired with just one part. Likewise, operator wiring faults are wiped out.
