Re: Rugged Case Options? #ubitx

You didn't read my later post on this - I was well aware of those traces and I did put 2 layers of Kapton top and bottom right up to the edge and another one wrapped around to help hold the 2 in place while sliding the board in.  I also used my milling machine to mill the side bulge (cover mounting screw channel) where the board mounting holes are.  I then put in some female/female standoffs (shimmed with thin flat washers to where they just allowed the board to slide over them.  Once in place, the boards are locked to the standoffs with 3 mm screws.  That way there won't be any sliding of the board at all.

In an earlier posting I warned about two traces on the edge of the PCB. I use the same box but anodized black 
and when you slide the PCB in the box you might create a short. The trace on one side is ground but the trace
on the other side is live. (I don't remember which one is on the top and which is on the bottom side). As there is
a solder mask you might not have a short at all time. I solved the problem by covering the edge of the board on
this side with Kapton tape. Careful when you slide the board in that you don't rip off the tape.
