Blacked rolled single-sided adhesive substrate is a special material used for manufacturing flexible circuit boards (FPC) and rigid flex PCBs. To understand its advantages, we can analyze it one by one from its three key features - "blackening", "rolling", and "single-sided adhesive".

The function of the covering film, commonly known as coverlay, is to protect the flexible circuit board from the erosion of dust, moisture and chemicals and to reduce the influence of stress in the bending process, mainly playing an insulating role.

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.
