Crystalline grain packaging structure and crystalline grain support plate thereof

The utility model provides a crystalline grain support plate is including support plate and copper foil layer. The support plate has the crystalline grain loading end, and the crystalline grain loading end is equipped with the crystalline grain bonding land and is located crystalline grain bonding land weld pad array on every side. The weld pad array includes a plurality of weld pads, and the crystalline grain loading end has a plurality of first corners, and the partial weld pad in neighbouring first corner is the ground connection weld pad. The copper foil layer covers the crystalline grain loading end, and has the interval between the edge of the edge of copper foil layer and crystalline grain loading end. The copper foil layer has a plurality of second corners that correspond first corner and follows a plurality of tip structure that extend in the second corner respectively, and the ground connection weld pad is covered by the copper foil layer. This crystalline grain support plate has electrostatic prote
