Twincam Posted April 11, 2016 Share Posted April 11, 2016 (edited) I've got a few components that the old spooge has became a bit weak! And a bit of vibration going on. Is hot glue from a glue gun ok for this or should I use something else??? Is the glue OK to use on caps too? Cheers Edited April 11, 2016 by Twincam Quote Link to comment Share on other sites More sharing options...
4stringslow Posted April 11, 2016 Share Posted April 11, 2016 Hot wax was frequently used to fix wires and some components in place so I don't see any problem using hot glue. Just be careful not to overdo it and end up insulating components so much that they could overheat. Not very likely with capacitors though.

mikeydee Posted April 11, 2016 Share Posted April 11, 2016 I use hot glue pen on caps and similar components I am sure there is better stuff too. But hot glue has the advantage of not messing up every thing else in the room. Quote Link to comment Share on other sites More sharing options...
icastle Posted April 11, 2016 Share Posted April 11, 2016 Hot glue is fine - just be thoughtful where you put it or you'll struggle like hell in the future if you need to remove the component(s). Quote Link to comment Share on other sites More sharing options...

[/quote] +1 I don't like using hot melt glue myself as it's a right pain when reworking and rather 'inexact' in application but I can't deny it [u][i]can[/i][/u] do the job pretty well. But note that the glue sticks are not all equal - some dry really hard and are not that good at adhering to non porous surfaces like PCBs and electronic components. So a bit of trial / error may be needed. There are specific products made for this application - two part 'Black Tak' and similar - but they do come expensive. Alternatively you can try a 'Superglue' (again various formulations better at some surface types and combinations than others) and maybe use with an Activator to finish the job quickly. Seems to work well for securing patch wires etc. Edited April 12, 2016 by rmorris Quote Link to comment Share on other sites More sharing options...
pfretrock Posted April 12, 2016 Share Posted April 12, 2016 (edited) I'd use silicone adhesive - but NOT the corrosive stuff. If it smells of acetic acid (sharp vinegar smell) don't use it. It is a bit more flexible than hot glue. Maplins may have some. Commonly used in electronics for holding down caps, preventing vibration damage. EDIT its a bit like clear bathroom sealant, but the electronics version is non -corrosive. Does not smell when uncured.

Twincam Posted April 12, 2016 Author Share Posted April 12, 2016 Used hot glue seemed to go ok. Was a bit harder to get neat though. And as said it may be a pain if it needs to be removed but it didn't feel much different to what I've seen in other amps. Quote Link to comment Share on other sites More sharing options...
3below Posted April 12, 2016 Share Posted April 12, 2016 What were we 'fixing down'? Picture would be useful if possible, otoh the deed is now done One plus of hot melt glue (not overdone) is that it can be 'broken' away from the circuit board when component replacement is needed.

Twincam Posted April 12, 2016 Author Share Posted April 12, 2016 A few caps needed re doing, and a few other little things got a little glue. Noticed the board with the larger components and heatsinks was flexing and making it vibrate so I put something non conductive and relatively heat proof under it, seems to of worked well.

3below Posted April 12, 2016 Share Posted April 12, 2016 Description and actions sound good, is what I would do / have done with crossovers and some amp components. I had never encountered 'spooge' word before Quote Link to comment Share on other sites More sharing options...
