Hi,Joseph!

3 decapsulation methods are known to me ,which work well depending
on your appliccation.
1."Automatic" decapsulation ,done with the decapsulators from
B&G Enterprises,Inc.
2880 Research Park Drive,Suite 100
Soquel,CA 95073
408.464.6540
Fax 408.464.6549
They have several models for almost all types of packaging.
I have no experience with their product.
2.Nitric acid , manually.This is ART and needs some experience.
3.Dipping in adequate solvents from
Dynaloy,Inc.
7 Great Meadow Lane
Hanover N.J.07936
(201)887-9270
This is done also manually,and Dynaloy has a booklet on the subject.
Good luck!
GABY
