CASE STUDY
Computer Manufacturer Requires EMI Shielding of Expansion Ports for Future Upgrades
A desktop computer manufacturer required EMI shielding of expansion ports designed for future upgrade and repair.
THE CHALLENGE
A desktop computer features a series of expansion ports designed for future upgrades. These ports need to be covered for both mechanical and EMI protection. Snap-in plastic covers provide decorative and mechanical protection, but lacked the necessary EMI shielding. A low cost EMI shielding solution was needed.
DESIGN REQUIREMENTS
- 40 dB reduction in EMI emissions
- Reliable electrical ground connection to chassis
- Easy disassembly in the field
- Low-cost, easy installation
KEY CUSTOMER REQUIREMENTS
- Kiss-cut resealable dielectric laminate with exposed conductive PSA for 360-degree peripheral grounding
- Pull tabs for fast removal of resealable dielectric film
- No mechanical hardware required for installation
- Low cost, short lead time
- Excellent EMI shielding
