Make it, produce it, solder it

FABISPElectronics is my thing, but... I never produce a board like this, i always use electronic specific software like eagle, and i make my boards or by etching process or by ordering it from board houses. So the big challenge is how a png image, can be a physical board. First i use fabmodules to vectorize it. Than i try to import that svg to my SRM20 software.
Rolland SRM20Ok first the SRM20 adventure ;) My SRM20 have a lower bed so i must put some high to make the pcb reachable by the milling cutter. I pick some wood, glue tape it to the bed. After that i use the click mill software from the SRM20 to make it completely flat. With a 3mm milling cutter i made a flat surface where i gonna put my pcb.
Leveling the bedWell the first mistake was done ;) i use wood to be the bed, but i don't recommend it, because wood is random fiber material not so good or stable over time. In Fablab Penela where i test it i don't have FR2 so i use a board from bakelite. Error 2, FR2 have a much much better behavior. Error number 3 I chose the wrong collet. My milling cutter's are 3mm Shaft, but my collet are 1/8" or 3,175mm So i must use a conic milling cutter.
My first milled pcb
Now with the help of fabMaster's in Fablab EDP i build a fabisp. I name it fabispPenela, in gimp change the logo. I mill it in MDX20. Everything easy and smooth. The challenge begin's in soldering it. We at fablab try to adopt a new approach. We are trying to solder all the component's via hot air. So for this i use gimp to make a solder paste mask. like this. After that i apply it in pcb than i pass the solder paste populate the board with the component's and applied the hot air to it. And voilá the board was ready :) Double check the connections and it was in did great. Tip's and trick's i use an android app as microscope. aTools
