0.006mm Shielding CCL / PCB Electrolytic Copper Foil
Description:
Electrolytic copper foil is an important material for the manufacture of copper clad laminates (CCL) and printed circuit boards (PCBs) and lithium ion batteries. In the rapid development of today's electronic information industry, electrolytic copper foil is called the "neural network" of electronic product signal and power transmission and communication. Since 2002, the production value of China's printed circuit boards has entered the third place in the world. As the substrate material for PCBs, CCL has also become the third largest producer in the world.
Electrolytic copper foil production process is simple, the main process has three: solution foil, surface treatment and product slitting. Its production process seems simple, but it is a combination of electronics, machinery and electrochemistry, and it is a production process that requires particularly strict production environment.
Features:
1. the treated foil in gray or red
2. High peel strength
3. Good etch ability
4. Excellent adhesion to etching resist
Application:
1. Phenolic resin board
2. Epoxy board
