Terminology: Printed Circuit Board

CAA Intelligence Sets Sail for a Shared Future

The “Automation Terms” column introduces automation-related terms every day, so as to contribute to the popularization of automation knowledge.

Chinese：Printed Circuit BoardEnglish：Printed Circuit BoardDefinition：The printed circuit board (PCB) is formed by etching copper foil on an insulating substrate to create conductive pathways that meet the connection requirements of electronic components, allowing for the installation and interconnection of electronic components. As the physical carrier of electronic systems, the PCB forms a network of conductive pathways through etching processes on the insulating substrate, achieving electrical interconnection and mechanical support for electronic components. Its role is akin to the “nervous system” of electronic devices, with most electronic devices, from miniature medical implants to spacecraft control systems, relying on PCBs to establish stable current paths and signal transmission channels.Term Example:In addition, the solder mask coating on

printed circuit board, with the plasma treatment, can also obtain certain roughness and high active surface, thus improving the solder coating adhesion.

Additionally, before applying the solder mask, treating the printed circuit board surface with plasma can also achieve a certain level of roughness and high activity, thereby enhancing the adhesion of the solder mask layer.
