CASE STUDY
EMI Gasket That Does Not Shed Particles Required for Electronics Component Manufacturer
Parker Chomerics multi-planar z-axis electrically conductive foam EMI gaskets are ideal for applications where foreign object debris (FOD) is a concern.
CUSTOMER CHALLENGE
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.
DESIGN REQUIREMENTS
- 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 REQUIREMENTS
- Conductive woven fiber for superior shielding
- Non-shedding material to prevent particulation
- Die-cut gasket with PSA backing for peel and stick assembly
- Economical
SOLUTION
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.
CONCLUSION
Parker Chomerics SOFT-SHIELD 4850 fabric-over-foam EMI shielding gaskets offers a conductive woven fiber for superior shielding, which can be easily cut to shapes with PSA backing for peel and stick assembly.
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.
