Building PCB's - Laser Printer Transfer Method

These are some photos of my current PCB Build Process using the Laser Print Transfer Method and PCB FAB-in-a-BOX transfer materials.

The Goal is Quick and Easy PCBs - From Computer Art to finished PCB was about 20 minutes.

Starting with Art printed on a Laser Printer, this is a simple SMD project.
Cover the page with another piece of paper.

With tape, place a piece of FAB-in-a-BOX Transfer Paper over the Art.
Put the new page into the printer, and print the Art again.
Now, Ready for the Laminator.

Now, Getting ready to Laminate the FAB-in-a-BOX Green Film

First pass through the Laminator
I use a Folded Teflon Sheet as a Carrier

Second pass, at a different angle.

NOTE: After many experiments, nothing that I have used works better than the GBC H-65 Laminator from Fab-in-a-BOX!!!

Its all about pressure, at the right temperature, at the right time. Other laminators over heat, then roll after a short time lag, this is due to the heating section and rollers are a short distance apart inside the laminator.

GBH Laminator "heats via the rollers", therefore Heat and Pressure is applied at the same time.

Ready for Etch
I use Ferric Cloride. For this size of board - about a 1/4 thimble full on a soft sponge brush. I have found that it fast and it undercuts much less than the other alternative acid method.

Examples of the Results

Before Etch
After Cut to size, Holes Drilled and Solder Wipe
Ready for part loading

The bottom board is a finished PCB - ready for SMD components.

This is a previous attempt and example of Direct Paper to PCB transfer, It worked great, but I lost the magic of how to do it correct! I am not sure which; Paper, Temperature and Pressure that I used. Darn.

This is a more recent High Resolution Toner Transfer Project.



  1. Danial,

    Solder Wipe -
    - cover board with a little liquid Rosin
    - with very little Solder on the Iron tip
    - quickly move the tip back-and-forth heating many traces at once
    - while still hot, wipe with a dry cloth
    - it is easy with a little practice
