CONSISTENT QUALITY, GLOBAL STANDARDS, UNMATCHED RELIABILITY
- KEY POINTS OF APPLICATION FOR TESTING STANDARDS
Priority should be given to using the GB/T series standards for domestic trade in China
The international market is mainly based on IPC-4101E and IEC 61249-2 series standards
High frequency copper-clad laminates require additional reference to GB/T 43801-2024 and IPC-4101 high-frequency material specifications
Special substrates (metal based, flexible, ceramic based) require corresponding special standards
International core applicable standards
- IPC-4562 Metal Foil for Printed Wiring Boards
- JIS C 6481 Test method manual
- JIS C 6485 Evaluation Reference
- IPC-4101 D Specification for base materials for rigid and multi-layer printed boards
- IPC-TM-650 Test method manual
- IPC-4412 Specification for finished fabric woven“E”glass for printed boards
- UL-94 Test for Flammability of plastic materials for parts in Devices and Appliances.

- HANDLING AND STORAGE
- Handle the Copper Clad Laminate,CCL with clean gloves to avoid being discolored and oxidized.
- Avoid direct sunlight. Keep away from water or high temperature and humidity area.
- Shelf day storing the boards indoors at normal temperature≤35℃ and humidity 70% RH is 12 months.
- Avoid strong Copper Clad Laminate,CCL in bent position or lean against a wall. Place them on a Level surface to prevent warping and twisting.
