SHN: shown: See Part number > Symmetrical parts for explanation. SHSS: socket head set screw: A set screw with a socket head (usually implying a hex socket, driven with a hex key. SI
Implementing motorized focusing offers an additional measurement dimension by focusing on the area to be examined and performing alignment and deviations from alignment on the scale of microns. This is relevant in the adjustment phase as well as final testing and examination phases of integrated systems.
The HOMS system was also tested by two independent groups (one from Ball Aerospace and the other from the Goddard Space Flight Center) using different test instruments. The European Space Agency also contributed to the verification process by providing an engineering model of the Faint Object Camera to provide additional verification.

The precise placement of the new unit onto the prepared pad array requires skillful use of a highly accurate vision-alignment system with high resolution and magnification. The smaller the pitch and size of the components, the more precise working must be. Finally the newly placed SMD is soldered onto the board.
An aligner, or mask aligner, is a system that produces integrated circuits (IC) using the photolithography process. It holds the photomask over the silicon wafer while a bright light is shone through the mask and onto the photoresist. The "alignment" refers to the ability to place the mask over precisely the same location repeatedly as the chip ...
