Abstract

Process liquids used in manufacture of electronic card assemblies are normally handled in large tanks in which the entire assembly is immersed. Removal of protective coatings or encapsulants for purposes of repair or replacement of defective components requires the use of solvents. If these solvents were applied to the card by immersion in a large bath, every component of the card would be exposed to these solvents which could cause damage to some of them. The invention is a fixture for directing and confining process liquids to a designated area of the circuit card. The engineering drawing shows the essential features of the fixture and includes a SMT component that is having a protective encapsulant removed.

Fixture for Handling Process Liquids during Manufacture or Rework of Electronic Packages

      Process liquids used in manufacture of electronic card
assemblies are normally handled in large tanks in which the entire
assembly is immersed.  Removal of protective coatings or encapsulants
for purposes of repair or replacement of defective components
requires the use of solvents.  If these solvents were applied to the
card by immersion in a large bath, every component of the card would
be exposed to these solvents which could cause damage to some of
them.
     The invention is a fixture for directing and confining process
liquids to a designated area of the circuit card.  The engineering
drawing shows the essential features of the fixture and includes a
SMT component that is having a protective encapsulant removed.
