PCB circuit board copper foil basic knowledge

PCB circuit board copper foil basic knowledge

Copper foil (copper foil): an anionic electrolytic material, a thin, continuous layer of metal foil deposited on the substrate of the circuit board, which serves as the conductor of the PCB. It easily adheres to the insulating layer, accepts the printed protective layer, and forms a circuit pattern after etching. Copper mirror test: A flux corrosion test that uses a vacuum deposited film on a glass plate.

PCB Industry Chain-Deep Analysis

PCB Industry Chain-Deep Analysis

Printed circuit board (hereinafter referred to as PCB) is a finished board that uses insulating substrate and conductor as materials and designs and makes conductive patterns of printed circuits, printed components or a combination of the two according to the pre-designed circuit schematic diagram. Its main function is to use board-based insulating materials to isolate the copper foil conductive layer on the surface to realize the interconnection and relay transmission between electronic components, the current along the preset line in a variety of electronic components to complete the amplification, attenuation, modulation, decoding, encoding and other functions, to achieve the interconnection and relay transmission between electronic components.

Basic knowledge must read: PCB circuit board component packaging

Basic knowledge must read: PCB circuit board component packaging

Packaging refers to the circuit pins on the silicon chip, with wires connected to the external connector, in order to connect with other devices. The package form refers to a housing for mounting a semiconductor integrated circuit chip. It not only plays the role of installing, fixing, sealing, protecting the chip and enhancing the electric and thermal performance, but also connects to the pins of the package shell through the contacts on the chip, and these pins are connected to other devices through the printed wires, so as to realize the connection between the internal chip and the external circuit.
