Milling and soldering WIFI chip

Shopbot and Vinyl cutter

I initally tried to mill the WIFI ESP8266 PCB board on the Shopbot, but it came out much larger in scale than it should have been. So instead I decided to vinyl cut it: Tips on cutting copper:
1) The copper traces are quite narrow and so to get a clean cut I should re-stick the copper to an epoxy film. Sticky side of the copper should be applied to sticky side of the epoxy. Apparently the cutting process may kick up some of the traces if the copper is cut when it is still on its original substrate.
2) Use a smaller force than for cutting vinyl - I am going to used a force of 75g.

I got really sick and did not manage to complete assignment.
