Die Cutting Polyimide Heat Resistant Adhesive Tape
Overview
FUNSMT die-cut polyimide tape is pre-cut into dots, squares, and custom shapes from premium PI film rated to 300°C. The high-performance silicone adhesive bonds strongly yet removes cleanly without residue, with excellent dielectric strength for wave soldering masking and high-voltage insulation.

FAQ
-
Q: Can these patches handle wave soldering temperatures?
- A: Yes, these PI patches are designed to withstand temperatures up to 260°C–300°C, making them ideal for wave soldering and reflow processes.
-
Q: Will they leave a mark on the gold contacts (Goldfingers)?
- A: No, our high-grade silicone adhesive is designed to peel off cleanly even after high-heat exposure, leaving zero residue.
-
Q: Can you provide custom sizes or shapes for specific PCB layouts?
- A: Absolutely. We support full OEM/ODM die-cutting services for any shape or dimension required for your specific project.
