Final solution for toner transfer method

[Maneco]

Hi!

this morning (saturday workshop for prototypes ) i came across and tried a new kind of paper :the protective paper that comes in "Contact  Adhesive "paper...maybe someone has already tried it,but is the best i have used for this method ...i just cut a A4 sized contact paper peel it and throw the actual adhesive film (in my case i gave it to my daughter as she was playing here     )   ...printed the pattern in my laser,and ironed it into wool cleaned copper board...around one minute...then a hot water bath,and the paper peels perfectly from the board,no "sharpie corrections"

I hope this is a valuable contribution

Best!

Hey Maneco, creo que nunca se menciono esa posibilidad, suena bastante interesante.

Yes, using the siliconized release paper for sticky labels, etc. is an old trick for doing toner transfer. The problems are (a) it releases too well, so the toner flakes off if you don't handle it carefully from printer to PCB, and (b) there's no blue layer sticking to the toner for extra void coverage. Your traces come out skinnier than with PNP and with more voids.

well,i never tried pnp before(not available here),but this paper i tried today gave me the best results so far ( i have tried all kinds of glossy papers,even magazine pages   )

Thanks for your replies!

Always great to have a report of what works, and what doesn't.
If you are searching for info on this "sticky label backing paper", a good word to use is "Avery", because that appears to be a USA brand name for adhesive labels.
In fact a google search for   avery pcb toner   got 50,000 hits, and the first 10 (only ones I checked) were good.

I hope never to make a PCB myself ever again :icon_wink:but, I wonder whetehr a spring-loaded cernter punch would help for getting drill holes in the right place?
