CASE STUDY
Contract Manufacturer of Computer Screens Requires EMI Shielding Around Display
Discover how one contract computer manufacturer used a Parker Chomerics EMI shielding solution to enhance shielding around a display.
CUSTOMER CHALLENGE
A contract computer manufacturer is using an existing handmade Kapton® copper shield for EMI shielding around a display. This solution is not providing adequate shielding and does not provide dielectric protection around the part.
DESIGN REQUIREMENTS
- Needs to provide shielding around a display yet provide a dielectric protection around the part.
- Desire to have a simple, low-cost shield complete with adhesive features, fold lines and grounding tape.
- Meet CISPR 22 and FCC Part 15 class B shielding limits.
KEY CUSTOMER REQUIREMENTS
- Low cost, short lead time
- Excellent EMI shielding
- UL 94-V0
SOLUTION
Parker Chomerics offered an Engineered Laminate solution featuring CBL-XX-3102-2400 material. The copper offers excellent shielding and can be soldered to if necessary. The .0762mm thick PVC provides a thin dielectric for easier folds and is still UL 94-V0.
The part has PSA tape along the material flow axis of our rotary die cutting machine, so product throughput is high and the customer gets the adhesive they requested.
CONCLUSION
Parker Chomerics Engineered Laminate solution featuring CBL-XX-3102-2400 material provided the contract computer manufacturer exactly what they required.
The laminate has pressure sensitive adhesive (PSA) for ease of application and can be soldered if necessary. The part can also be cut on a high speed rotary die cut machine for increased material yield and stable labor costs.
