The list of materials for PCB manufacturing mainly includes the following:
1. Substrate material: basic material used to make PCB. Common ones include FR-4 (phenolic tissue paper), FR-5 (epoxy resin tissue paper), FR-6 (matte glass), CEM-1 (cotton Paper epoxy resin), CEM-2 (tissue paper epoxy resin), CEM-3 (glass cloth epoxy resin), CEM-4 (glass cloth epoxy resin), etc.
2. Copper foil: used to make circuits and electrical connections on PCBs. Common thicknesses are 1-3oz.
3. Printing ink: used for printing circuit patterns and text logos.
4. Solder mask ink: used to cover the PCB surface to protect circuits and electrical connections.
5. Soldering ink: used to cover the PCB surface for soldering components and plug-ins.
6. Chemicals: including etching solutions, film removers, cleaning agents, etc., used for chemical treatment in the PCB manufacturing process.
7. Other materials: such as drill bits, diamond grinding wheels, tungsten steel blades, etc., used for mechanical processing in the PCB manufacturing process.
These materials play different roles in the PCB manufacturing process. To ensure manufacturing quality and efficiency, various materials need to be selected and used rationally.
