Indispensable when high precision of etching is required, with a small step of the board tracks.
Provides uniform etching, does not "etch". Much more effective than ferric chloride.
Fine crystalline powder, chemically pure (reagent grade).
Packing: package 500 g
Method of application: dissolve the contents of the package (500 grams) in 2.5 liters of water with a temperature of 50°C. The etching process is recommended to be carried out at a solution temperature of about 40°C (maximum approx. 50°C).
Feedback on application:
1. The etching capacity for copper is 40% more than that of ferric chloride of the same mass (approximately).
2. The etching time is 30% longer than that of ferric chloride.
3. Works very well on small details and paths without eating them.
4. Less aggressive to PCB mask.
5. Does not leave stains on clothes, easy to wash off. Chemical glassware can be easily washed from the solution.
Attention!
Observe safety precautions when working with the drug! Avoid contact with eyes, work in rubber gloves and goggles, do not store near flammable materials. Hygroscopic, keep tightly sealed.
In case of contact with eyes, rinse with running water and consult a doctor.
