Introduction: Etching
Step 1: Things Required
1. Copper clad
2. Etching solution (30%hcl and 6%h2o2)
3. Correction pen
4. Nail polish remover

4. Nail polish remover
Step 2: Preparing the Etching Solution
Mix HCl acid (hydrochloric acid )and H2o2 (hydrogen peroxide ) in 4:1 ratio.
AND THIS IS ALL U NEED .
*NOTE - the concentration of reactions and the mix ratio can have a varied range . These are just the values which I prefer.

Step 3: Making Circuit
Draw your circuit on copper clad with the help of correction pen
Step 4: Method
After drawing the circuit place it in the solution wait for 2 to 3 hours the solution will turn green from transparent
........
Take out the circuit wash it with water clean the water with dry cloth rub the pen ink with nail polish remover and your circuit will be ready
