what is the PCBA Circuit Board Assembly?
PCBs are the foundation of modern electronic devices. They mechanically support and electrically connect electronic components. The boards themselves are made of laminate material, such as fiberglass or composite epoxy, and contain conductive pathways that connect different parts of the board. These pathways are printed or inscribed onto the board according to the predetermined PCB design.
Types of PCBs
The main types of PCBs include:
Single-layer PCBs are the simplest type of PCBs and are coated with a single layer of conducting material and a layer of solder mask. The PCB’s components are marked with a silkscreen.
Double-layer PCBs have a layer of conducting material on both the top and bottom of the board, which gives them more flexibility and a smaller size than single-layer PCBs.
Multi-layer PCBs have more than two conductive layers and are used in more complex applications.
Other common types of PCBs include flexible PCBs, rigid PCB, and flex-rigid PCBs.
