Title: How to make PCB's steady into the enclosure
Post by: Outtagetme on June 14, 2013, 03:44:27 PM
Hi guys,
so I'm building a madbean clone of the OCD, but I'm not using PCB-mounted pots and there's no place to drill holes for the PCB standoffs on the pcb itself.
How can I make the PCB steady into the enclosure?

3M doublesided foam tape.

Or blue tack.

Hot glue works nicely in certain situations as well.

I use 3M as well.  Specifically, I use the VHB (high bond strength) made for plastics and metal.  It is strong as bull.

So you mean that I can put some doublesided tape on the solder side of the PCB?
I was thinking about that but I wasn't sure I could do that.
Newbie question :)

Thank you!

Depends. Not the typical double sided tape, the scotch kind. It should be the kind with foam in the middle, which acts to raise the PCB up a bit as well as insulates it from the enclosure or pots.

Double sided foam tape.

Yep, the thick foamy double sided tape between the pots and the solder side of the board.
Works great.

Umm I don't think I have ever seen it here in shops (I'm from Italy). So, why not using normal electrical tape, you just connect one end to the other (so the adhesive part connects the two ends) and you get a "diy" doublesided tape, and you can make it as thick as you want. Will it work this way?

Ok sorry I think I have just found it. The name is "white doublesied foam tape", I think I found what you were talking about. http://www.leroymerlin.it/catalogo/nastri-adesivi/nastro-biadesivo-schiuma-bianco-24-x-24-mm-31878336-p
Can you confirm it?

It could work, except I can't see if it's double sided.

This is what Google turned up as an option in the US. You can look for something similar overseas I'm sure.

The link says "biadesivo", so yes, it must be double sided.

You can also solder component leads to the pots and essentially convert the pots into PCB mount pots. Thicker leads like those on a 1n4001 diode work great for this...

Yep it is doublesided, and looking at the link you provided it seems more or less the same. It should work, then!

You got it right! biadesivo=double sided tape

Now that's a great idea! I knew how to convert a pcb mounted pot to a "normal" pot with breadboard, just not the opposite!

Thanks everyone for the help!
