EMI GASKET — SEAM DESIGN REVIEW
Use exact supplier data; this sheet provides no generic approved compression, fastening or
compliance value.
Enclosure / revision / seam / interference problem:
Required frequency range and system EMC test / operating modes:
Separate environmental seal requirement and test:
Mating metal / plating or finish / masking / fluids / salt / condensation:
Gasket grade / filler / binder / profile / adhesive / supplier:
Free height min/nom/max (mm):
Assembled gap min/nom/max including lid deflection (mm):
Compression = (free height - gap) / free height * 100%
Illustrative: 2.00 mm / 1.50 mm -> 25%; min = (1.90-1.60)/1.90 = 15.8%; max =
(2.10-1.40)/2.10 = 33.3%.
Supplier permitted compression and force range / document section:
Fastener pattern / stiffness / groove / mechanical stops:
Corrosion evidence for this exact interface:
Form-in-place preparation / bead / cure / adhesion controls if applicable:
Inspection criteria / lot traceability / service replacement:
Baseline and candidate test evidence / unchanged test setup:
Opening cycles / environmental conditioning / repeat results:
Decision / unresolved conditions / supplier review:
