Epoxy board (FR-4) is usually used as a thermal insulation material and is suitable for use in lithium battery distribution boxes. FR-4 is a glass fiber reinforced epoxy resin composite material with excellent insulation properties and good mechanical properties.

Due to its high temperature stability and chemical corrosion resistance, FR-4 material can be used to manufacture thermal insulation boards and is suitable for use in electrical equipment, electronic products and battery components. Therefore, FR-4 epoxy board is a common choice for thermal insulation of lithium battery distribution boxes.

The processing of FR-4 epoxy board can be carried out through the following steps:

Cutting: Use a saw blade or CNC cutting machine to cut the FR-4 sheet to obtain a substrate of the required size.

Drilling: Use a drill bit to make holes on the FR-4 board as needed to meet specific assembly requirements.

Molding: FR-4 board can be hot-pressed, using high temperature and high pressure to process the raw material into a product of the desired shape. This step is usually carried out during the board manufacturing stage.

Edge grinding: Remove burrs and trim corners of the cut FR-4 substrate to ensure smooth edges.

Surface treatment: Spray and polish the surface of the FR-4 board as needed to improve the appearance quality and surface performance.

The above are the basic steps for processing FR-4 epoxy boards under normal circumstances. The specific processing methods can be adjusted according to actual needs and equipment conditions.
