Creating a non-adhesive "island" within a tape die cut may appear straightforward, but achieving it with precision requires a highly controlled manufacturing process. For a customer project, CFS produced a custom polyimide die cut featuring precisely placed non-adhesive zones. The project was completed in our ISO Class 7 clean room using a Delta ModTech precision rotary press, ensuring the accuracy, cleanliness, and consistency required for the application.
Step 1: The material that will become the “island” is laminated to a temporary liner |
Step 2: The island is die cut and waste removed |
Step 3 and 4: These are performed at virtually the same time with the help of camera driven computer servos. The “island” (adhesive side down) is removed from the clear temporary liner and precisely placed onto the adhesive side of another polyimide tape. By mating the adhesives, a non-adhesive island is created. |
Step 5: Another clear liner is laminated onto the exposed adhesive side of the tape containing the islands. |
Step 6: The linered tape is then die cut to the final shape and the waste removed |
Final product is a polyimide die cut with an island of non-adhesion in the middle |
