Shielding Components, Modules and Boards from Shorts, Shock and Stress
All PCB boards, assemblies and components depend on dielectric materials to insulate leads, wires and other components against crosstalk. But not all dielectric materials perform equally. Many organic solutions turn brittle with heat or age, or do not fully protect delicate elements against environmental factors such as ultraviolet light, chemicals, vibration or mechanical stress caused by thermal cycling.
Dow Consumer Solutions' industry-leading portfolio of silicone-based dielectric materials combines reliable insulation with value-added performance and protection for applications spanning the entire PCB system assembly value chain.
In addition to insulating packaged components and board assemblies, low modulus silicone coatings and encapsulants from Dow Consumer Solutions provide excellent protection against mechanical shock and vibration. For applications subject to thermal cycling, we offer a range of silicone gels that provide a flexible, almost fluid dielectric coating. These advanced materials insulate and protect delicate parts – such as solder joints and wire bonds – from the effects of thermal expansion. This explains why our products are often the materials of choice for PCB system assemblies rated to perform reliably at temperatures ranging from -45°C to 200°C and above.
