Hello,

I am trying to make a pcb using the toner transfer method and have a
couple questions regarding it. I hope someone can shed some
expertise on them for me.

1) I purchased the Staples picture paper and printed a pattern out
on my Laser printer but I am unsure as to which side to print on. I
am assuming that you print on the glossy side but after doing that
and ironing it on a clean acetoned PCB the pattern seemed to
transfer to it but its not as dark as I have seen on some websites
and some traces are broken in the middle. My trace width is .020
which is not that thin. So I thought maybe I am using the wrong side?

2) How long do you heat the paper for? I tried it for at least 1
minute to where it was so hot it sizzled in the water. The back of
the paper was turning yellowish from the heat but maybe it needs to
be longer? It peeled off pretty easy and it left a whitish substance
on the traces which I am assuming is paper. I scrubbed that off but
the traces like I said are kindof weak.

Thanks again for all your help!
