Sandia's search for environmentally sound cleaning processes for the manufacture of electronic assemblies and precision machined parts.

摘要

As part of the DOE's commitment to minimizing waste at the national laboratories and its production agencies, Sandia has embarked on a program to reduce, and where feasible, eliminate hazardous liquid waste by-products of cleaning processes used in the manufacture of electronic assemblies and precision machined parts. The program is being carried out in conjunction with three DOE production agencies: Allied Signal-Kansas City Division, EG&G Mound Applied Technologies, and General Electric Neutron Devices Division. We will discuss the methodology used to coordinate such a program across the DOE complex, involving as it does, hundreds of components and thousands of DOE-specified cleaning processes. We will also discuss three specific projects to replace chlorinated solvents in cleaning manufacturing processes: (1) alternative solvents used to remove solder flux residues during electronics assembly manufacture (2) alternative solvents used in ceramic header fabrication, and (3) alternative manufacturing processes that eliminate the need for solvent cleaning of precision optical components prior to mounting. 2 refs., 3 figs., 1 tab.
