How To Select Electical and Electronic Resins
Electrical and electronic resins are adhesives, greases, pads, stock shapes, tapes, encapsulants, potting compounds, thermal interface materials, and electrically conductive substances used in electrical, electronic, and semiconductor applications. There are several basic types of electrical and electronic resins. Electrically conductive products provide low resistivity and are often used to prevent electrostatic discharge (ESD), electromagnetic...

Buying AdviceTop
Do you have any advice for people relative to buying or using electrical resins and electronic compounds?
6 answers
Research, research, research. Its a pain, because most companies don't have very good websites for researching or selecting the best resin for the application.
~Kent M., Process Engineer, South Bend, IN
Yes, its very helpful to use electrical resins because they work well for the new technology.
~Bongani M, Research & Development, Johanessburg, RSA
Push suppliers to be transparent about environmental concerns.
~Dave C, Quality Control, Cary, IL
Consider for long term performance instead of cheapest price.
