Melamine resin used on worktop surfaces [18] and some plastic dishes. [19] Diallyl-phthalate (DAP) used in high temperature and mil-spec electrical connectors and other components. Usually glass filled. Epoxy novolac resins used for printed circuit boards, electrical encapsulation, adhesives and coatings for metal.
A small transformer potted in epoxy. The surface visible on the right is formed by the potting compound that has been poured into the plastic box. In electronics, potting is the process of filling a complete electronic assembly with a solid or gelatinous compound.
Molded plastic cases and structural parts can be made by a variety of methods, offering tradeoffs in piece part cost, tooling cost, mechanical and electrical properties, and ease of assembly. Examples are injection molding, transfer molding, vacuum forming, and die cutting. Pl can be post-processed to provide conductive surfaces.
Cost is a factor in selection of integrated circuit packaging. Typically, an inexpensive plastic package can dissipate heat up to 2W, which is sufficient for many simple applications, though a similar ceramic package can dissipate up to 50W in the same scenario. [1] As the chips inside the package get smaller and faster, they also tend to get ...
