By Ferric chloride hexahydrate can be very simple implementation of the diy pcb corrosion.
1. change all the shortcomings of ferric chloride, the corrosion rate is very fast.
2. It is blue and clear etching solution, no more dirty phenomenon.
3. etching process is clearly visible.
4. by 1:7 exchange water, can corrode 10 * 15cm single-sided PCB, about 10-15 pcs.
by 1:7 'Blue etchant' into the water.
Step 2: Process of Corrosion Pcb Board
