PCB fabrication (homebrew): Difference between revisions

Using a laser printer or copier, this does not work with an inkjet printer, to print an image of the PCB tracks on glossy paper. Laying this printed side onto the de-oxidised and de-greased copper laminate and using an iron at a high temperature, on the rear of the paper to transfer the toner from the paper onto the copper. After soaking in water to remove the paper, the toner now transferred to the copper laminate acts as an etch resist.<ref>[https://web.archive.org/web/20130604031907/http://fullnet.com/~tomg/gooteepc.htm ''Easy Printed Circuit Board Fabrication, Using Laser Printer Toner Transfer''] by Thomas P. Gootee, 2007</ref> This can also be used to print component side parts and legends. ''Press'n'Peel'' is similar to this method. If you don't tin the board, coat the copper laminate with rework flux to prevent it oxidising.<ref name="mh">''[http://www.electricstuff.co.uk/pcbs.html How to make really really good homemade PCBs]'' by Mike Harrison</ref>
