FR4 is a code name for flame resistant materials and best performance in epoxy boards. Epoxy board can withstand high temperature up to 180 ° C,… Continue Reading Core-Tex FR4 epoxy board processing technology
The epoxy board is a laminate which is mainly made of epoxy resin adhesive, paper, cotton and other substrates. There are many types of epoxy boards, including 3240 epoxy board, G11 epoxy board, G10 epoxy board, FR-4 epoxy board, etc. Their performance is similar and there are differences in details.… Continue Reading How do epoxy board manufacturers look at the quality of epoxy boards?
There are many other names, including FR-4 light sheet, FR-4 fiber sheet, FR-4 epoxy sheet, FR-4 flame retardant sheet, so many names also reflect the wide application of FR-4 fiberglass sheet from other side. . 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
