Generally speaking, the substrate of printed boards can be divided into two categories: rigid substrate and flexible circuit board. Generally speaking, an important type of rigid substrate is copper plate. Using reinforcing materials, soaking in resin adhesive, drying, cutting, and stacking into billets, then covering them with copper foil, using steel plates as molds, and forming them under high temperature and pressure in a hot press. Generally speaking, multilayer semi cured sheets are semi-finished products during the copper plate covering process (most of which are soaked in resin in glass cloth and dried). Do you know what circuit boards are made of?
The FPC circuit board is mainly composed of solder pads, through holes, installation holes, wires, components, connectors, fillers, and the main functions of each component are as follows:
Solder pad: Metal hole for soldering component pins.
Through hole: Metal through hole and non-metal through hole, used to connect component pins between layers.
Installation hole: used to fix the circuit board.
Wire: A copper film used to connect component pins to the power grid.
Connector: Used to connect components between circuit boards.
Filling: Used for copper plating on ground wire networks, which can effectively reduce impedance.
Electrical boundary: used to determine the size of a circuit board, and all components on the circuit board must not exceed this boundary.
