As I mentioned before, the main problem I have with SMD’s on JeeLinks is applying too much solder paste.
Well, I just got a few test stencils in the mail from Paul Badger of Modern Device, who is experimenting with a laser cutter and a variety of plastic sheets.
So here’s my first DIY solder paste stencil jig for JeeLinks:
In good DIY fashion, it’s made of things I “happened” to have lying around, such as a piece of “foam” used by photographers, i.e. a few millimeters of foam (PU?) sandwiched between two thin plastic sheets. It’s easy to cut so size, and a bit of a cushion might actually help level out the pressure when applying paste. I used hot glue to fix a couple of pcb scraps to the board, and a single line of adhesive tape to fix the stencil.
This jig opens up to take a panel with 4 JeeLink boards, like this:
It’s all about getting the alignment right, of course:
Will it work? I’ll report in the next few days…
