Copper clips are commonly used in high-performance electronic components and are a key interconnect component widely used in high-power packages, such as MOSFETs (metal oxide semiconductor field effect transistors) and IGBTs (insulated gate bipolar transistors). Copper clips can create electrical and thermal paths between lead terminals, chips and substrates, thereby improving the thermal management performance of the equipment, and are an important component of the power module structure.

In the past, it was mainly used for making standard parts and structural parts on sand casting molds, and less used for making casting mold bodies

Processing the metal sheet into the required shape is the cold forming process. Standard cold forming technology is sheet metal processing including stamping, forging, extrusion, rolling and drawing. Stamping is the most popular cold forming technology in sheet metal processing and is used in multiple industries, including automotive, electronic communications, aerospace, construction hardware, etc.

The progressive die is the same as the general cold stamping die, which is composed of: punch, concave die

Metal stamping involves placing cold metal between dies (some processes also heat the material). The metal material is pressed into the desired shape to create a larger tool or component. Some people in the manufacturing industry may refer to metal stamping as pressing.

Laser cutting is an industrial process used to cut sheet metal with a powerful, focused laser beam. Guided by a CAD file, the laser cutter glides over the surface of the sheet metal and melts, burns, or vaporizes away material to cut the desired patterns into it.
