Abstract

The present technique provides a multi-tile detector and a process for assembling the multi-tile detector using a flexible structure and intermediate electrical connections. The present technique minimizes edge gaps between adjacent detector tiles by coupling the detector tiles to the flexible structure and then flexing the flexible structure to close the edge gaps. Intermediate electrical connections, such as interlayer solder bumps, also may be used to minimize visible artifacts associated with tiling of the detector tiles. The present technique also may use a plurality of soldering materials having different melting temperatures to facilitate multiple soldering steps that are nondestructive of previous soldering steps.
