CASE STUDY
Electronics Component Manufacturer Requires EMI Gasket Which Does Not Shed Particles
THE 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/ 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
CONCLUSION
Parker Chomerics SOFT-SHIELD 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’s composition does not shed particles like the competitor’s materials did, thus preventing system damage.
THE SOLUTION
The recommended solution for this electronics component manufacturer was to use a Parker Chomerics SOFT-SHIELD conductive foam gasket material as an ideal solution.
Because SOFT-SHIELD is made of conductive fibers and not a coating, it does not shed particles that can cause system damage.
SOFT-SHIELD 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
Electrically Conductive Foam EMI Shielding Gaskets
Parker Chomerics family of SOFT-SHIELD electromagnetic interference (EMI) shielding gaskets are designed for EMI shielding and grounding applications that do not require a weather seal. Ideal as an economical low compression force solution, the SOFT-SHIELD brand consists of two types of gaskets:
- Conductive fabric wrapped around non-conductive low-density foam: Commonly referred to as “Fabric Over Foam” these gaskets are available in stirp form and a variety of catalog and custom profiles.
- Silver plated fibers knitted into low-density foam: These products are made in sheet form and are die cut into custom shapes.
We’re constantly innovating in our drive to create the most advanced EV solutions.
