E-mail Bonding

[Mike McLane]

I have a terminal strip circuit board that I need to affix to the back of a matrix of pots so that they are bonded into a unit (but electrically insulated). The normal 3M double stick stuff I can get at Home Depot is ideal except that I'd love to find something with a stronger more permanent bond. I've experimented with epoxy, but it really doesn't adhere to either surface satisfactorily.

Hot glue? I have seen other builders use it, but I haven’t use it before.

3M VHB series is their mega-duty adhesive line. There are different double sided tape options.

Re: Hot glue. . . No worky. I have to adhere all 6 pots to the circuit board so that they can be handled as a unit. . . easier to install, etc. By the time I'd get them all doctored the first 3 would be cold already.

Benny, I sent an inquiry into the 3M tech as to that very product. Awaiting a reply now. Know any sources where I don't have to buy an mega-duty sized spool of the stuff ???

Amazon has options. It’s not cheap. But, you can hold up a highway sign with the stuff.

Home depot often stocks it, I've also bought it on amazon before. VHB tape is good stuff.

Also, I think I’d characterize hot glue as the monkey wrench of adhesives: the wrong tool for every job.

GuitarPCB has some pretty tacky adhesive I've used...

Gum Wadz - #1 Best PCB Mount Adhesive - GuitarPCB

Gum Wadz, a double sided Gel PCB Mount Adhesive that's 100% non-conductive and features a thick cushion to firmly stick the solder side of your PCB to the enclosure or back side of the potentiometers.

They are out stock now. I might have a couple of squares if you'd like a sample.

Yes, I found the Scotch brand equivalent of the VHB. Had it left over from another goofy project. Appears to be just what the Dr. ordered.

They always seem to be out of those Gum Wadz adhesive strips. I’ve got a couple left and think they’re perfect, but can’t find them anywhere. Don’t suppose you found another supplier or an equivalent anywhere?

Thanks!

No, but wish I had Maybe 3M has something similar?

Cheers!

This gel tape is similar.

Why not standoffs and machine screws and kep nuts? Epoxy doesn't stick to epoxy board?

but I think even the “light duty foam“ in the rubber adhesive would work great for PCB holding. And, pretty inexpensive.

Pcbs don’t always have holes for the standoffs. This is more for adding small daughterboards, or in this case adding a Tentacle to a Muff circuit. It’s just so easy and quick and world’s incredibly well.

Perfect, thank you!

Well, yeah, I meant drill holes. I make my own circuit board from G10 for tube amp for the past 20 years-ish, nothing quite as strong as 4 SS #8's with nylon spacers and kep nuts!!! I've used epoxy, as well as clear silicone caulk to hold chips onto g10, no problems yet.....
