Etched circuit card If you have actually a well subjected and cleanly developed circuit board, the succeeding MOKO Printed Circuit Board Assembly etching procedure is no longer actually crucial, here the possibility of making errors is not almost as fantastic just like exposure and development.

We etch PCB with sodium persulfate, which is dissolved in a concentration of 220 grams per liter in regarding 45 levels of warm water. We always prepare the etching option fresh, the etchant is low-cost enough for it. You can additionally make use of the PCB engraving service numerous times until the PCB engraving efficiency declines. Do not dump the utilized etching option into the drain, but collect it and take it to the contaminated materials factor!

There are different ways to get the circuit card into the etchant, you can make use of a tight-fitting plastic can with a snap cover, which is continuously trembled a little during the PCB board etching option.
