Chip glue packaging refers to the use of glue to fix the chip on the substrate to form a stable package structure. The glue can fill the gap between the chip and the substrate to form a protective layer, which plays the role of fixing the chip, protecting the chip and cooling the heat. Glue usually uses epoxy resin, silicone and other materials, with good adhesion and high temperature resistance. In addition, there is a technology called \"glue chip\
