Reflow oven: real board 1

So the stencils for the (first) test boards arrived - yay! The stencils were from OSH Stencils and of the polyimide film type.

Reflow oven: the controller has arrived!

Barely had I finished the last post about the plan for a reflow oven and the ControLeo 2 controller arrived! (The US and French postal services must have really been on the ball this past week...) The kit comes with the following (as advertised): ControLeo2 with Reflow Wizard software pre-installed ABS enclosure with UL94-5VA [...]
