What consumables are used for lamination in circuit boards

In the production of circuit boards, the pressing process involves various consumables, mainly including :

1.Laminated steel plate: used for the lamination of multi-layer boards, usually made of imported steel such as West German steel or Nippon Steel, which is ground and heat-treated to achieve high hardness and flatness.

2.Silicone rubber pad: Common brands in the market include Rogers, Shinetsu, Dow Corning, etc. It is mainly used for PCB lamination, providing good cushioning and thermal conductivity.

3.Kraft paper: Used in the bonding process of FPC, PCB, etc., it plays a role in insulation, water absorption, pressure reduction, buffering, and heat transfer.

4.Release film: usually made of PET material, with high tensile strength and impact strength, used for separation during the lamination process.

5.Adhesive blocking film: such as PE, PU, TPU, etc., used to fill the space during circuit compression, control the overflow amount, and maintain product quality.

6.High temperature adhesive release film: The main components are polyester resin and polyethylene resin, which have good heat resistance and filling properties, and are suitable for lamination of FPC high-precision boards.

7.Burnt iron plate: composed of silicone rubber and iron plate, with thermal conductivity function, suitable for FPC fast press machine.

8.Red/green silicone pad: composed of silicone rubber and fiberglass cloth, with good thermal conductivity, suitable for FPC press and fast press machines.

9.Vacuum airbag: a silicone rubber product suitable for FPC vacuum presses, with good filling, buffering, and thermal conductivity.

The selection and use of these consumables are crucial for ensuring the quality and production efficiency of circuit boards.
