Prototype PCBs fast

Making PCB at home is time consuming matter. How to make prototype PCB fast at home require some skills. I bet fastest and messiest thing would be using resist-pen and paint track directly on PCB board. But this process is limited by complexity of your circuit. More complex your circuit is – more mistakes you can make.

It is better to manage one good PCB layout software like CadSoft. This is more than enough for hobby projects. For smaller PCB’s you don’t even have to buy it. It has free limited version where PCB size is limited to 2.5×4”. It is rich in component libraries o make prototyping PCB even faster.

For prototyping you will need etchant solution (like Fe2CL3), laser printer, iron, glossy photo paper and copper board. And start prototype PCBs fast:

  • First step – draw your schematic to schematic capture program.

  • Then place parts on the board and route the board;

  • Print trace image in a glossy paper;

  • Transfer toner to PCB using hot Iron;

  • After paper stuck to PCB soak it with water and remove;

  • Etch the board;

  • Clean toner from PCB;

  • Drill holes;

  • Now you are ready to solder.

Find mode details on prototype PCBs fast. Good luck.

One Response to “Prototype PCBs fast”

  1. Nick Johnson Says:

    Ah… this method again…

    My experience is:
    (1) it’s really hard to get the layout to transfer from photo paper to pcb evenly.
    (2) Once you’ve done that, it’s hard to get the photo paper off of the copper.
    (3) Etching doesn’t work evenly unless you have some sort of heater/agitator

    Additionally, one should mention that while designing your pcb, you might try to use traces NO SMALLER THAN 8mils
