Do you know the characteristics of halogen-free plates? Today, the editor of Anhui Xinchen optical new materials Co., Ltd. will introduce it to you.

According to jpca-es-01-2003 standard, copper clad laminates with chlorine (C1) and bromine (BR) contents less than 0.09% wt (weight ratio) are defined as halogen-free copper clad laminates. (at the same time, the total amount of ci+br ≤ 0.15%[1500ppm])

Reinforcing plates are also called stiffeners, reinforcing plates, reinforcing plates, supporting plates, reinforcing plates and stiffeners. Reinforcing plates are mainly used in buildings, oil pipelines, mechanical equipment, electronic products, etc. FPC is widely used in electronic products. The reinforcing board mainly solves the flexibility of the flexible circuit board, improves the strength of the plug-in part, and facilitates the overall assembly of the product.
