Description / Abstract:
Introduction
At a meeting in February of 1989, the Institute for
Interconnecting and Packaging Electronics Circuits (IPC) and the
Electronic Industries Association (EIA) agreed to co-author a joint
solderability test method. At subsequent joint meetings, many of
the test method requirements were agreed upon, but an impasse was
reached regarding steam age time and temperature.
The Steam Aging task group was started in April, 1989 following
the Spring meeting of IPC. The ad hoc group was formed by members
representing the IPC and the EIA to support the efforts of the
Joint IPC/EIA Solderability Testing committee.
The goal of the group was to obtain the data on which to make a
recommendation to the joint committee as to the temperature and
time for steam aging preconditioning for solderability testing. It
was necessary to define control levels which were satisfactory to
both organizations.
