HOW TO MAKE A PRINTED CIRCUIT BOARD

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)



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

Step 4. Use Iron to heat-press the Image onto the
copper

layer from copper layer transfer the pattern on the
PCB


After transferring the layout using heated iron

 Step 6. Use the Etching process to Remove unwanted
copper using fecl3

Step 7. After the etching we required drilling to mount
component

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

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
