RepRap Gen7 PCB… check!

Posted by  via T(h)inker it!

Today went back to Alt­Lab for a lit­tle learn­ing expe­ri­ence. A great friend of mine, Fer­nando Afonso, came to Lis­bon to the launch of MEO Kanal, a prod­uct he helped bring­ing to life. Since he was here, he was invited by Alt­Lab to give a small work­shop on “PCB Mak­ing… The Fer­nando Afonso way”. :)The method used was Toner Trans­fer, where you print the cir­cuit lay­out with a laser printer on cheap mag­a­zine paper (the more glossier is bet­ter), then, with the toner side over the cop­per side and woot… the “sand­wich” off it go into a slightly mod­i­fied lam­i­na­tor (around 10 times) and the it’s sub­merged in freez­ing cold water.The low qual­ity mag­a­zine paper it’s eas­ily scrubbed off the pcb and it’s ready to the acid bath.
We used Acid Cupric Chlo­ride as etchant, when the pcb is sub­merged  it turns into a… kryp­tonite green… spooky I say!In the end we’ve got a Gen­er­a­tion 7 Elec­tron­ics pcb for the Prusa Air… next step, buy the com­po­nents and sol­der­ing it 😀
