Special pcb stock for toner transfer technique Price: $3.00 - By Special Request. Please email

This is a 4" x 5" FR4 .031" double sided piece of copper clad circuit board material with a special copper nodule coating applied to the surface. It feels like a very fine sandpaper and the textured copper surface is supposed to bind with the toner better than the *normal* polished copper material. My circuit board guy tells me that this is THE stuff for use when making boards using the heat transfer of toner. The textured copper surface really grabs the toner and produces sharper traces. I have a limited supply. If you have had lackluster results etching pcbs using the toner transfer heat laminator technique, you might want to try one of these sheets.
