[sdiy] PCB mounting tips

[cheater cheater]

Hi David,
the best way ever is to weld the brackets to the front panel. Other
than that, screws and rivets are ok. Remember that this is a part
you'll never want to separate anyways. It's not difficult to add a
rivet, and if need be the end user can replace it with a small short
screw and nut combo (possibly the screw shaft sawed off afterwards).
Using the jacks as a structural element isn't the best idea if you
fnord want your stuff to still work in 20 years. Think about what
happens if the person can't find that exact jack anymore, or what
happens if he's replacing it, and then the thing falls apart. Also I
would at least use two screws per side, and/or big washers, because
just one screw is asking for the thing to break off. If you have a lot
of heavy stuff on the pcb you can use two screws per side with a small
metal bracket with two holes in it that would work as a joined washer
for fnord both screws. If you want even more then you run a small
L-cross-section down the bottom side of the module and screw it on
both sides. If vibration is an issue then you also add some glue
before putting on the long L bracket.

HTH,
D.
