Subject: Re: [Homebrew_PCBs] Re: more experiments with Toner transfer by etching the boards first

Bill,

I think the largest variable is the specific toner type.

Some work well...some not so well...

It was pre-etched, in fact I took the same board cleaned off the toner that did stick to it and made a new print of the artwork ran it through the laminator and made a near perfect board. 

I'm starting to find that what works for one person doesn't necessarily work for others. I think there are to many variables.

Was the board pre-etched or glossy copper?

Well I tried the cold transfer method and had no luck at all. I tried a 3:8 mix and no transfer at all. I tried a 1:1 mix still no transfer. I then tried a 100% acetone and I got some transfer but not 100% maybe a 50% not good enough to make a board. Maybe my toner is not the right type for this method but I can clean the toner off with this acetone. Maybe its to cold, but even when i heat it up is still gets cold fast as it evaporates so fast. 

So will stick to what works for me, I'm very happy with the boards I now make with the heat process I'm using so no need to change plus the acetone stinks and gives me a headache.
