What chemicals can eat through resin Answered

Does anyone know what chemicals can eat through resin? My dad gave me a strobe light which the timing was out on but the electronics were incased in resin so I can't access them. Any help would be useful

The typical epoxy used in IC packages is usually removed with solvents like fuming Nitric or Sulfuric acid (there are places that will "decap" an individual chip for you.)

See Bunnie's Blog and a Detailed description of decapping. A high percentage of ICs are "bricked" by the process.

This is a very large scale version of that...possibly too large scale. Acetone might work, but I doubt there's any solvent that wouldn't ruin the exposed components before the encapsulated bits are exposed.

 I really don't think there is. Like gmoon said, acetone might work, but by the time you buy the acetone and go through all the trouble of carefully extracting it, it might be better just to buy a new one...

But is there a solvent that I can add drop by drop and keep it away from the components?

I dunno, we're all just speculating...you'll have to try one of the liquid solvents already mentioned. But I'm betting it won't be easy...

Methylene chloride might work, but it is NASTY, sold as paint stripper or in auto stores as "Gasket remover".
