The materials used by battery PCB assembly manufacturers mainly include the following:
1. Substrate: The basic material of the battery PCB board, usually FR-4 epoxy fiberglass board.
2. Copper foil: Conductive material used to form battery circuits.
3. Insulating materials: used to prevent short circuits between different circuits and ensure the safety of the battery.
4. Protection board: an important component to prevent battery overcharge, over-discharge, short circuit and other problems.
5. Shell: Shell material used to protect the battery PCB board and internal components.
6. Connecting wire: The wire used to connect the positive and negative terminals of the battery to the positive and negative terminals on the PCB board.
7. Terminal: Terminal material used to connect the battery to external devices.
8. Fasteners: screws, nuts and other fasteners used to fix the PCB board and internal components.
9. Adhesive: Adhesive material used to fix the PCB board and internal components.
The assembly of the battery PCB board also requires the use of some auxiliary materials, such as labels, gaskets, sealing rings, etc. The use of these materials should be selected and assembled according to actual needs.
At the same time, safety issues need to be paid attention to during the assembly process, such as avoiding short circuits, overcharging, etc., and ensuring the quality and stability of materials.
