Electronic Repairs: Removing component stabilizing gunk

[DanSteely]

Hi All,

 

Often in active speakers, the amplifiers have glue/resin/gunk squirted seemingly randomly over the larger componants like caps.

 

In the best scenario the gunk is soft and can be prised off.

 

In the worst case the stuff is hard and solid.

 

In the later case what strategies do you use to sofen or remove it?

 

Many thanks.

I've always just ended up nibbling it away with side cutters. Never founds any product to dissolve it?

I concur! Remember to replace it though when you've done the repair - it's important for preventing fatigue in solder joints. You need proper non-corrosive silicone such as https://uk.rs-online.com/web/p/sealants/0494102/ It takes quite a while to cure but cures fairly rigid.

Thanks chaps.

No magic tricks then.

Oh well.

Side cutters to the rescue.

Possibly a Dremel in some circumstances.

 

Or the bin...
