What do you mean by "2A/H CCL" in the PCB board?
Phenolic paper laminate covered with copper foilIt is composed of insulating impregnated paper (TFz 62) or cotton fiber impregnated paper (1TZ- 63) impregnated with phenolic resin laminate formed by hot pressing, two surface adhesive tape can be attached to a single alkali free glass impregnated fabric, coated with copper foil. The side of the printed circuit board is mainly used in radio equipment.
Flexible polyester coated copper filmIs a strip of material with polyester film and copper formed by hot pressing, the application will be rolled into a spiral shape on it. In order to strengthen the internal equipment or moisture, often with epoxy resin pouring it into a whole. Mainly used for flexible printed circuit and the printed cable, as a connector of the transition line.
Copper foil epoxy glass cloth laminated boardIt is a common material for metal printed circuit boards
Copper-clad laminatesIt is a kind of deposited copper plate made of polytetrafluoroethylene plate and coated with copper foil. It is mainly used as printed circuit board in high frequency and ultra high frequency circuit
Copper clad phenolic glass cloth laminateIs the use of alkali free glass cloth laminate impregnated with epoxy phenolic resin formed by hot pressing, one or both sides coated with copper foil, has the advantages of light weight, good electrical and mechanical properties, easy processing and so on. The surface is light yellow, with three cyano two amine as curing agent, the surface is pale green color. With good transparency. For printed circuit board in the main working temperature and high frequency radio equipment.
