The application of dispensing machines in the chip packaging industry

The more precise a product is, the stricter the control of its manufacturing process, and the higher the requirements for its manufacturing process. In order to improve production efficiency, the degree of automation is also higher. Taking the chip packaging industry as an example, automated dispensing equipment must be used multiple times during its packaging process, rather than manual dispensing.

1： Bottom material filling

Many technicians have encountered such problems during the chip flip process, where the fixed area is smaller than the chip area, making it difficult to bond. If the chip is subjected to impact or thermal expansion, it is easy to cause the protrusion to break, and the chip will lose its expected performance. To solve this problem, it is necessary to inject organic glue into the gap between the chip and substrate through a fully automatic dispensing machine, and then cure it. This not only effectively increases the connection area between the chip and substrate, but also further improves their bonding strength, providing excellent protection for protrusions.

2： Chip bonding

PCBs are prone to displacement during the bonding process. In order to prevent electronic components from falling off or shifting from the surface of the PCB, it is necessary to use a fully automatic dispensing machine to dispense glue on the surface of the PCB, and then place it in an oven for heating and curing. This way, electronic components can be firmly bonded to the PCB.

3： Surface coating

In addition, after the chip is soldered, it is necessary to apply a layer of low viscosity and good fluidity epoxy resin between the chip and the solder joint through a fully automatic dispensing machine and cure it. This not only improves the appearance of the chip, but also prevents external erosion and stimulation, which can effectively protect the chip and extend its service life.

When packaging small items like chips, if they are manually glued, the dispensing speed cannot be slow and it is difficult to control the amount of glue stably. This not only affects the production speed of the product, but also may affect the quality of the product. Therefore, for such precision operations, automation equipment is the best choice for manufacturers.
