Gluing pots to a PCB

MmmPedals · January 14, 2011, 03:30:02 PM

One method i use for boxing up pedals is to hot glue the pots to the back of the pcb. I also use this method to fill gaps between the back of a board and right angle pots.
Never imagined there is anything in the glue (silicon?) to corrode the metal. Am I wrong about that?
Is there an easy alternative in a squeeze tube to get this job done that is safe for electronics?

When I don't use standoffs, I use a combination of double sided foam tape and these: http://www.buildyourownclone.com/board/viewtopic.php?f=9&t=20231&start=0&st=0&sk=t&sd=a&hilit=pot+condoms that way the board isn't glued down if I need to debug or fix something later on and everything is well secured and insulated.

I'm not sure about corrosive properties in glue though.

A good tug on the hot glue will pull it loose. so its not not a problem to service. Plus I need something that could fill the gap between right angle pots and the board, thiker thwn double sided tape.

Hot glue is great for electronics. Safe as milk.

I don't know if we are thinking of the same thing. I am not talking double sided clear tape, I'm talking about foam tape which has a substantial thickness. I am sure hot glue would be fine, but I thought I should clarify.

I made some general comments about RTV (silicone) a while back... http://www.diystompboxes.com/smfforum/index.php?topic=85406.msg716301#msg716301

With silicone the trick is being able to identify the non-acid-cure stuff from the blurb before you buy it & open the tube

Totally safe
