Post-Etch Topside Layout Labeling?

2005-12-07 by soffee83

Sorry to spit out this "message flood", but I'm having more questions 
than answers lately. :(

I tried my first PCB labeling the other night with my usual toner 
transfer method and it didn't go very well. I couldn't help but notice 
how the "raised" copper areas of a double-sided board prevent the 
paper from laying flat on the board and screw up the transfer in the 
low areas.

Is the toner/iron process a lost cause under those circumstances, or 
does anyone know of a workaround? FWIW, I use my previous brand of 
JetPrint photo paper for non-trace jobs, where I need a clean black 
transfer with no left over paper. This is the type where the paper 
sort of slides off after soaking, leaving a light "goo" on the surface 
which comes off easily with soap. I found a method of getting much 
more consistent transfers onto metal, by spraying a light mist of 
Krylon clear acrylic on the substrate beforehand. Unfortunately, this 
didn't seem to help on the PCB labels.

                              -Thanks Again!
