Chip encapsulation means that the shell made of metal and ceramics is glued outside the chip through the bonding property of glue, which can play a role of fixing, stabilizing and protecting the chip. And the adhesive effect of black glue is good. It will not drop. It can also increase the stability of products. Black gel also has certain resistance to temperature and solvent. When we use black gel to do chip dispensing, we can use multi axis automatic dispensing machine. From the name, the multi - axis glue machine is equipped with multiple glue valves. It can be used at the same time in the process of glue. It can replace the employees' work. Moreover, the dispensing efficiency is high. The dispensing efficiency of a multi spindle automatic dispensing machine is several times higher than that of a staff dispensing. Compared with the traditional manual dispensing way, the multi axle dispensing function can be used for a long time. Because the chip packaging of the motherboard is less demanding for dispensing, so it is necessary to select the suitable size of dispensing needles according to the properties of black gum and dispensing requirements, so as to avoid glue dispensing and the quality of products.
