Abstract

See full text

A multi-module radiation detecting device, a radiation detecting module for incorporation in a multi-module radiation detecting device, and a method for assembling a multi-module radiation detecting device are provided. The radiation detecting module includes a carrier substrate and a radiation detecting tile mounted over the carrier substrate. The module includes interconnection structure for connecting radiation detecting elements in the radiation detecting tile to conductive contacts on a base substrate. The module facilitates attachment and detachment of the module relative to the base substrate and relative to a test fixture used in test and burn-in operations. The module is constructed to isolate the radiation detecting tile from thermal and/or mechanical stresses produced at the interconnection interface during attachment and detachment for test and burn-in, assembly, and rework operations. As a result, the module can be used to produce a multi-module radiation detecting device having enhanced reliability. The module can help maintain device reliability despite rework operations, and can thereby reduce rework costs.
