Description

1, jie film, photographic film is sandwiched between two layers of thin film, tear side first, is a little hard to tear, try a few times more
2, then the paster, copper is a bit it is ok to clean, flat, try not to have a bubble
3, stick, slightly heating electric iron, need not too hot, a fixed role
4, printed circuit board film, suggestion is to use film, can achieve the highest precision, if no requirements for accuracy Use LiuSuanZhi to print.
5, exposure, the printed pattern on the plate, use common energy-saving lamps for 10 minutes, if there is exposure machine for 1 minute, the sun didn’t try, should be about 30-60 seconds , the exposure process clearly, because the coating will change color when exposure, change from light to dark blue. You could easily see your circuit diagram appear on the board.
6, enhancement, remove the another layer of protection film, in the developer (developer water in proportion of 1:100, against the premium of 10 grams), when developing stick cotton slightly rub test board
7, etching, there’s no need to say more water saturated solution of etching agent
8, etching, membrane, remover pro 1:6 0 or 70 water, soak the board for a few minutes
