Hello,

I am a new comer here, glad I have discovered that forum!

I have been building my amateur radio projects mostly "dead bug style" but I would like to try the use of transparencies and pre sensitized copper board.

Never done that before so the questions might sound a bit silly, here I go:

1 - I am using DIPTrace to create my PCB / Artwork: I read online that the side with toner ink has on the board side. So it means that I need to print my artwork, "mirrored", doesn't it?

2 - While using positive pre sensitized copper board (MG Chemical for instance), I need to print my artwork in "positive", right?

I haven't started any experiments with this, so I am sure I could have figured out things out along the way but I thought I would ask before ruining these rather expensive boards... !

Thanks guys
Tony

So you're using the UV method? If you don't have the light box, you can etch the boards with chemicals, which doesn't require a UV light box or sensitized PCBs (so it's much cheaper). I make PCBs with the "toner transfer method".

That's another good option.

Actually last night, I had a single sided PCB from R.S. left over and I decided to give the toner transfer method a try.

I have in the past tried with various glossy photo paper but it felt like a real pain. I went through a couple of boards before I could get a decent result.

So I decided to use some 3M transparencies ! And wow! I was truly surprised of how easy it was to transfer the toner, to peel off the sheet and overall the quality of the transfer looked awesome!

I might reconsider doing my future project's PCBs using the UV method, even though I would like to try and compare with the toner/transparencies.

As you mentioned, regular single sided board are much cheaper than the pre sensitized ones.
