Application 08/152,192
APPENDIX
27. A method of testing, marking, sorting and packing
different classification of integrated circuit package units
(ICPUs) that are initially enclosed in carrier tubes
comprising,
a) automatically positioning carrier tubes containing
ICPUs in a position that locates the ICPUs in a dead bug
orientation,
b) automatically moving the carrier tubes with the ICPUs
in the previously positioned dead bug orientation to a
conditioning station,
c) automatically unloading the ICPUs from the carrier
tubes at the conditioning station in the dead bug orientation
such that the ICPUs are unenclosed, and automatically
conditioning the individual, unenclosed ICPUs with heat,
d) automatically transporting the conditioned ICPUs,
while unenclosed and in the dead bug orientation, from the
conditioning station to an environmental test station and
automatically testing the electrical parameters of the
conditioned ICPUs at the environmental test station while the
ICPUs are in the dead bug orientation,
e) automatically cooling the conditioned and unenclosed
ICPUs while the ICPUs are in the dead bug orientation and
automatically transporting the cooled ICPUs, while the ICPUs
are unenclosed and in the dead bug orientation, from the
environmental test station to an ambient temperature test
station,
f) automatically testing the cooled ICPUs at the ambient
temperature test station for quality assurance while the ICPUs
are unenclosed and in the dead bug orientation and thereafter
automatically transporting the quality tested ICPUs, while
unenclosed and in the dead bug orientation, from the ambient
temperature test station to an orientation station,
