Securing a PCB

---

I'm planning to make a controller this summer, but the PCB I'm using is a lot smaller than the case I need to use. How do I secure the PCB so it isn't flopping everywhere?

Me, I'd just use hot glue because I have a gun right here.

I have a hot glue gun, too; would that hold it down securely enough? It's a fightstick, it'll get bashed around a lot. A bit rough.

If the PCB has mounting holes you can use screws through the case, a standoff or spacer and a nut.

If you want, you can countersink the case for flat head screws.

If you don't want any holes in the case at all, you can use one of my new favorite pieces of hardware, a "round base T-nut".
Glue the base to the inside of the case with epoxy and mount the PCB with screws.

No mounting holes in it, sadly. If it helps, it's a 360 controller mobo.

Yes, that does help.

I would buy some rubber grommets that fit the two holes on the pointy ends and the two slots at the top.
I'd glue in (4) 1/4-20 T-nuts, use a flat washer underneath and a bolt on top of the grommet.
Shock mount and everything.

Oh, wow, that's perfect. Thanks!

Double sided Foam Tape, or even Better Servo Tape

Servo tape is used to hold Down Servos in RC Cars, Planes, helicopters etc.

You've got me thinking, obsidianchao.

I can get a wired Xbox 360 controller at Family Dollar for $11.
I'm not sure if they implement the whole deal, but 11 switch inputs, 2 joysticks,
a headset interface and a UART would be a great deal.
I'm sure that the switches and things are not the best quality, but I wouldn't be reusing them.

Hmm...

Hot glue

Hot glue is the best idea...
