Two primerless encapsulants from Dow Corning should bring greater adhesion and stress relief to electronic applications, along with a fast, room-temperature cure. Both deliver an uncharacteristic toughness and peel strength for a silicone dielectric gel material, the company reports. Dow Corning(reg) 3-4220 Firm Gel is one part blue and one yellow, facilitating visual inspection for complete mixing. Dow Corning 3-4219 Firm Gel, a clear version, contains no dye or UV indicator, and is designed to help prevent radio-frequency interference in applications involving wireless communications.

At the Design News webinar on June 27, learn all about aluminum extrusion: designing the right shape so it costs the least, is simplest to manufacture, and best fits the application's structural requirements.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
