Removeing plastic from encapsulated electronics and coils

[Unregistered]

I am needing a safe method to remove plastic from around electronic parts and coils without damageing the components. Anyone know a safe method. Thanks, Mark

Is it Plastic or Encapsulate?

Depending on the make up of your components and the Encapsulate!

Could be plain old acetone, Carbosol, or some nasty stuff like Toluene!

Some Encapsulates can just be heated up to 150F and pealed off!


Depending on what your talking about it could be just Diesel fuel.

Register!

Send a photo of what your talking about would help!

What Color is it?

Is it Rubbery?

Hard?

Clear?

More info on the table is needed!

Is it really old? Some shellac derivative conformal coatings will
dissolve in alcohol.
A heat gun will soften many coatings, but if it smokes it's too hot.

Is it blobbed onto the components?

Try to wet one corner of it with acetone.

Acetone will attack most plastics.

Maybe you can get a start point and just peel or tear it off?

If only is for to remove plastic, you can use thinner. This help for to remove. You must put attention during the process. After remove the plastic you must to dry and clean very well.

Do you remember Alexismex's attempt to disassemble a Mineoro 210?
Some of the "secret" circuitry was covered in black gunk, and I asked him how he had removed it. Here's his reply:

I tell you my secret 70% to depotting all the epoxy and polyester, urethane and silicon resin ...USE cold (freeze) and hott temperature (500-600°) alternating , the resin brake gently very quickcly and many times the electronics resist very well (because the temp do not go direct to it, always the resine "brake" 3-4mm above the ic,resistor,inductor, etc...)...it is the essence of the technique, imagine the tools and you have the other 30% of the secret.you can see in the photo the scraped away in flakes and chunks.

don't know if is good for you... but an heat gun can help much in such situations....

Kind regards,

Thanks for all the info.
