PCB circuit board corrosion is what kind of process
aluminum-based circuit boards, PCB circuit boards, PCB board, PCB board, PCB board, PCB board, PCB board, PCB board, PCB board, a circuit board, LED circuit board and a multilayer wiring board is widely used , Aerospace, defense, telecommunications, home appliances, environmental protection, medical and industrial control.
When rinse with water, the way with bamboo and other objects scraped paint (when the paint from the liquid out, easier removal). If the scratch is not easy, just fine with hot water and then dry, clean and polished with sandpaper to reveal a shiny copper foil, a printed circuit board is done. in order to save results, usually Cangzhou Lida circuit board circuit board factory mainly produces single-sided circuit boards, circuit boards,
When ferric chloride solution is typically configured with 40% water and 60% ferric chloride, ferric chloride, of course more, or with warm water (not hot water, to prevent the peeling paint) allows faster reaction rate Note that a certain corrosive ferric chloride, so as not to touch the skin and clothing, like the reaction vessel with an inexpensive plastic pots, let go of the circuit board. starting from the edge corrosion PCB board, when the paint is not described The copper foil is corroded after the timely removal of the circuit board to prevent the paint off after the corrosion of the useful line
