Abstract:
1. A dual-chamber-loop environmental tester for memory modules comprising: a first environmental chamber and a second environmental chamber, each environmental chamber comprising: wherein the first heated air from the first heating unit is forced into the first environmental chamber and flows past the memory modules in the first environmental chamber to heat the memory modules, wherein the first heated air having passed the memory modules in the first environmental chamber becomes the first return air expelled from the first environmental chamber into the second heating unit; wherein the second heated air from the second heating unit is forced into the second environmental chamber and flows past the memory modules in the second environmental chamber to heat the memory modules, wherein the second heated air having passed the memory modules in the second environmental chamber becomes the second return air expelled from the second environmental chamber into the first heating unit; wherein air is recycled through the first environmental chamber and the second environmental chamber by the first heating unit and the second heating unit, whereby memory modules are tested within the first and second environmental chambers by pattern generators on removable pattern-generator cards outside the first and second environmental chambers that are separated by the backplane.
