How to clean the printed circuit board of the etching solution
The general use of water on the circuit board after washing to dry on the line. Meet the white clothing can be used to try some drift agent, but more difficult to completely clear.
Is the first two, on these two, the acidic etching solution on the use of the general multi-channel wash on it, but the alkaline etching solution in addition to washing with water, and some also with ammonia washing or thin Hydrochloric acid wash, so out of the board looks better
There are many kinds of corrosive solution of PCB board, such as hydrochloric acid + salt plate of acid corrosion solution, ammonia chloride copper alkaline etching solution, ferric chloride etching solution, sulfuric acid + hydrogen peroxide corrosion solution and so on, but the normal use
