Case Study: EMI Gasket that does not shed particles required for electronics component manufacturer
A large electronics component manufacturer was experiencing electrical shorts caused by a competitor’s EMI shielding gasket materials releasing particles into the system.
The manufacturer set out to replace these materials and also find shielding material with a pressure-sensitive adhesive (PSA) for peel-and-stick assembly.
Offering superior shielding performance
No release of harmful particles
Lower compression force requirement than the competitor’s product
Material offered w/ pressure sensitive adhesive (PSA) for peel and stick assembly
Easily die cut to shape of area necessary
KEY CUSTOMER REQUIREMENT
Conductive woven fiber for superior shielding
Non-shedding material to prevent particulation
Die-cut gasket with PSA backing for peel-and-stick assembly
The recommended solution for this electronics component manufacturer was to use a Parker Chomerics SOFT-SHIELD 4850 series conductive foam gasket material as an ideal solution.
Because SOFT-SHIELD 4850 is made of conductive fibers and not a coating, it does not shed particles that can cause system damage.
SOFT-SHIELD 4850 delivered better shielding performance than the competitor’s material and is easily converted to a die-cut shape from roll stock. This allowed for quick prototyping of sample parts for side-by-side testing.
SOFT-SHIELD 4850’s composition does not shed particles like the competitor’s materials did, thus preventing system damage. The material's Z-axis foam consists of silver-plated fibers embedded into UL 94 V-0 low-density open-cell urethane foam, achieving stable electrical performance as well as superb conductivity with extremely short ground paths.
