FR-4 fiberglass sheet is generally used for soft-packing base layer, and then wrapped with fabric, leather, etc.,… Continue Reading FR4 epoxy board processing method
The flame retardant of the early halogen-free CCL is mainly achieved by the addition of flame-retardants. Common flame-retardants are phosphorus and nitrogen-containing additive flame-retardants such as phosphate ester, poly-phosphoric acid, melamine, aluminum hydroxide, magnesium hydroxide, and so on. Due to the large amount, glass transition temperature (Tg), heat resistance, processability… Continue Reading Knowledge about the Halogen-free Materials of Epoxy CCL
Electronic yarn is a kind of spun yarn. Its diameter is about 4-9μm. Electronic yarn has finer diameter and better performance, so that it can be used in the electronics and other high-end areas. while it have higher requirements for the technology and funds, the price is also higher. “Electronic… Continue Reading The Supply Chain Status of one Important Raw Materials in Copper Clad Laminate (CCL) —-Electronic Fiberglass Yarn and Cloth
CCL—–Also known as the base material. CCL (Copper Clad Laminate) consists of wood pulp paper or glass fiber cloth as reinforcing materials with resin, and single or double-sided coated with copper foil, and laminated under high temperature and high pressure. It is also called a core plate when it is… Continue Reading Basic knowledge of CCL
