I use transparencies to produce overlays for making PCBs.
When I ran out I popped into Staples as usual, they did not have any in stock.
I was advised that I could purchase them online.
So, I did. I didn't get them from Staples, I go them here.
And guess what, they are better and cost less.
The side for printing isn't quite as rough as the ones I used to use, and for me this has a great benefit.
I did have a small problem where I would occasionally suffer a little "cracking" and "flaking" of the printed image, a disaster for PCB making.
These are far better for the job (probably the best I have come across), seems to dry very quickly and the ink does not end up sticking to the pcb.
I AM VERY HAPPY and will be ordering more!
