HOW TO MAKE A PRINTED CIRCUIT BOARD

BY:Jitendra Jangid AUG 2008

Required materials for PCB

1.) DIP trace software installed PC

2.)Glossy paper

3.)laser printer

4.) Household clothes iron

5.)Copper clad laminate

6.) Etching solution (fecl3)

7.) Kitchen scrubs (iron woolen)

8.) Thinner (e.g. acetone) 2BY:Jitendra Jangid AUG 2008

Step 1. Make the Schematic Circuit in Dip Trace software

Step 2. Transfer to board for PCB lay out (top view using software )



Step 3. Save and Print the PCB lay out on Glossy Paper

How we can Generate Protective Layer on

PCB


Protective polyester film


Put on the PCB


After placing the photo active foil on PCB than fed into the laminator to transfer green coating on PCB


After using heated laminator 16BY:Jitendra Jangid AUG 2008

Exposed to UV light


Remove photo active foil from PCB


Use solution to remove green layer from copper contacts using sodium carbonate


Final Green coated PCB
