Abstract:

A single-layer redistribution plate functioning as a space translator between a device under testing (“DUT”) and a testing PCB may comprise a hard ceramic plate. A DUT side of the plate may have pads configured to interface with a device under testing. Both sides of the plate may comprise traces, vias, and pads to fan out the DUT pad pattern so that the plate side opposite the DUT side has spatially translated pads configured to interface with the pads on a testing PCB. Fabricating a redistribution plate may comprise calibrating and aligning, laser milling vias, laser milling trenches and pads, copper plating, grinding and polishing, removing residual copper, and coating the copper surfaces.

Abstract:

A system for collecting light energy through smaller photovoltaic cells (PV cell) such that the length of the PV cell is much greater than the width. The PV cells may be linear strung together and placed within a recess of a frame or pan that is part of a PV module. The PV module includes a lens and waveguide which provide advantages for focusing and concentrating the light energy by positioning a waveguide over the smaller PV cell and engaging the PV cell with a lens such that the lens is held by the frame.
