Capacitor epoxy encapsulation pinhole

Epoxy Powder Pinholes

To resolve defects caused by pinholes, we address the ways in which the bubbles are caused and can be avoided. There are three major probable causes and those are either the Equipment, the Process or the Materials. It can happen that the heating element is not hot enough or the fluidized bed is not uniform and causes excessive bubbles.

Reliability criterion of film capacitor based on moisture diffusion

The current reliability criterion (RC) of the film capacitor (FC) is usually a fixed value, which does not consider the staged capacitance loss caused by moisture diffusion under high temperature and/or high humidity. The expected lifetime of capacitors would deviate far from the actual one. The moisture diffusion process of the encapsulated FC

Encapsulated Capacitor

Electronic encapsulation materials are chosen for their ability to insulate by three mechanisms: thermally, electrically and mechanically. Traditionally, such materials have included polyesters, cellulosics, or even thermosets. Each material has its limitations, and none proved capable of meeting all of Accumold''s needs. Foremost, it was essential that the material flow well and be
