Abstract

Accelerated thermal cycle tests are used to temperature-stress modules to determine their failure potential. The modules are placed in transport racks and moved to a thermal cycle chamber for stress testing. The nature of the testing is such that the modules are handled several times which poses a risk to the modules. A transport vehicle that is designed to protect the parts from damage and also has the flexibility to accomodate several styles of modules works as follows. A transport basket is approximately one inch in depth and of a length and width to be determined by the size of the thermal chamber to be used. A frame 1 is covered by an aluminum sheet 2 that is perforated with hexagonal holes 3.

Baskets for Environmental Module Testing

Accelerated thermal cycle tests are used to temperature-stress modules to determine their failure potential. The modules are placed in transport racks and moved to a thermal cycle chamber for stress testing. The nature of the testing is such that the modules are handled several times which poses a risk to the modules. A transport vehicle that is designed to protect the parts from damage and also has the flexibility to accomodate several styles of modules works as follows. A transport basket is approximately one inch in depth and of a length and width to be determined by the size of the thermal chamber to be used. A frame 1 is covered by an aluminum sheet 2 that is perforated with hexagonal holes 3. Aluminum rods (not seen) are of a size to fit through the hexagonal holes 3, in any configuration, to suit the loading needs as determined by the number and size of the modules to be tested. The rods are positioned to secure the modules against movement in the basket. The modules are stacked on their sides, in rows, and then the rods are inserted through the holes 3. The rods are deformed on one end to prevent them from going through holes 3. The rods also serve to support the stacking of modules.
