*Certified to IPC-4203/1: "Adhesive Coated Dielectric Films Use as Cover Sheets for Flexible Printed Circuitry and Flexible Adhesive Bonding Films."
Storage Conditions/Shelf Life
Polyimide coverlay composites will retain their original properties for one year when stored in the original packaging at temperatures between 4–30°C and below 90% humidity. Keep the material clean and well protected.
Coverlay should not be automatically discarded if storage conditions have deviated from these limits. We recommend that material that has not stored in these conditions be examined in a practical test before putting into production
Typical Data
All the polyimide coverlay is certified to IPC specifications and tested according to IPC Test Method TM-650. See Table 2.
