Printing the design
Printing the design
The perfect paper should be: glossy, thin, and cheap. The kind of stuff that looks lustrous and shiny when new, but so cheap it quickly turns into pulp when wet. Almost any glossy magazine paper will work. I like thin paper over thick one, and prefer recycled paper over new paper.
Select the paper such that it no heavily printed, preferring pages with normal-size text on white background. Avoid printing your layout over the large text-ed Headings etc this ink may some time get on yout PCB. Cut the paper to a size suitable for your printer. Try to get straight, clean cuts, in the border otherwise it may get stuck in the printer. An office cutter is ideal, but also a blade-cutter and a steady hand work well.
Be careful to remove all staples, bindings, gadget glue or similar stuff, as they can damage printer’s drum and mechanisms.
Else you can use A4 sheets as well (it might not work always that well) Once the circuit layout is in hand take a mirror image (this is because you are going to trace this image on the copper clad similar to past and peal tattoos) print of the layout on the Magazine or simple A4 paper (glossy papers are best for this purpose).
Next step is to prepare the copper clad. Cute the needed size of copper clad and rub the metal side with a kitchen scrubber or a fine sandpaper to make the surface clean and shiny. Metallic wool for kitchen cleaning purposes also works. Thoroughly scrub copper surface until really shiny. Rinse and dry with a clean cloth or kitchen paper.
