Raw flexible PCB material for hand etching single sided flexible circuit boards. Single sided 35 micron (1oz) copper with 45 micron polyamide dielectric. Material is hand cut to 6x9" size.

Etching flexible PCB is similar to FR4. Toner transfer methods work extremely well with an modified laminator as the board will roll through with the toner paper. We have had good results with down to 6mil traces reliable etch. There are many how-to guides available for hand etching flexible PCB, but I recommend this Instructable. We recommend using a Samsung Laser Printer as we have had really good transfers and they are very economical.
