EMC shielding in electronic products can be expensive and take up a lot of space on the printed circuit board. This is particularly the case for products that are produced in high volumes, such as smartphones, IOT sensors and automotive electronics. But this also applies to sensitive radar systems and specialist equipment in aerospace.
This allows the EMC problem to be caught at the source. This is possible at housing level, printed circuit board level, but even component level where CHO-SHIELD is applied directly to ICs.
Parker Chomerics has a range of electrically conductive coatings and paints in its program, tailored to each application.
The compound consists of a liquid carrier consisting of acrylic, epoxy, polyester or polyurethane, enriched with filler material of silver, copper or silver-plated copper. The compound to be applied can consist of one or more components and in some cases a primer is necessary.
Considerations include:
– Degree of EMC shielding
– Lifetime of the application
– Substrate of the coating
– Temperature stability
– Cost of the material
Parker Chomerics is a specialist in EMC shielding materials and thermal interface materials for critical electronics.
