Comparing Heat Seal vs. Pressure Sensitive Cover Tapes
June 24, 2026
Choosing between heat seal and pressure sensitive (PSA) cover tapes is a critical decision for SMT assembly. Let's compare:
Heat Seal Cover Tape
Pros: Excellent bond strength, consistent peel force, lower cost per meter.
Cons: Requires heat sealing equipment, higher initial investment.
Best for: High-volume production with dedicated sealing equipment.
Pressure Sensitive Cover Tape
Pros: No heat required, easier to apply manually, good for prototyping.
Cons: Higher material cost, potential for adhesive residue.
Best for: Low to medium volume production, prototyping, and field repair operations.
AcePlas offers both types in various widths to suit your production needs.
