How to mount a PCB board into a casing box that has no mounting holes?

[selrahc]

Hello everyone! I'm

I wonder how should I mount a PCB board when there are no holes to mount? The board is a double sided PCB, means there are routes on bottom and top of the PCB board.

I foolishly made a board without considering the mounting holes in the first place, and I routed it for a week.

I was wondering if there are any ways for me to solve this!

Are there something in the market that I can use?

Sorry for the foolish question.

Thanks everyone!

I would fasten some threaded standoffs to the case, using a strong epoxy.

Screw the board to the standoffs.

Hope this helps!

But there are no holes on the PCB board! how to screw them?

A corner mount would work, see the link below:

Those peg corner mounts are slick!

I've seen narrow plastic side rail mounts that can grip the board in slots, snap in or slide in. Anything that slips over the sides or corners cannot interfere with components and connections I suppose.

Could be a custom mounting solution to cut on your router. As long as there is room in your project box you plan to mount the works in.

In a pinch, al la cheap import fastening methods, nothing as simple as a support peg tray and silicon adhesive to secure it!

older pc systems had mounts that held the 'side' of a board, and installed into a hole in the chassis, could also be glued into place..

free by the handful at most computer repair shops...

..enjoy..

If there is no room to even use some kind of plastic edge connector, you could put a dab of silicone caulking compound on each corner of the board and "glue" the board to the case. Be absolutely certain that you give the silicone time to cure or you'll fry something. It won't matter if the silicone covers components if they are low wattage (low heat). Don't cover high wattage components or you'll trap the heat.
