Introduction to manufacturing process:
Use glue material, print it on cutting path and surface of component by steel plate or mesh plate as external protection of components.
common problem:
At the same time, a large number of bubbles will be produced on the inside or surface of the printing adhesive. These bubbles will affect the appearance of the product, and also cause the problem of product reliability.
Problem solving application:
After printing, vacuum is applied to the product in the cavity to pump the internal gas of IGBT to the surface, and then pressure and heating are applied tode-void.
