Printed Circuit Board
The Printed Circuit Board is the board upon which the IR array sits and is controlled. The above two images are of the top and bottom of the printed circuit board which was provided by John Geary (CfA, Harvard). The first image shows the 4 quadrants: I (lower left), II (upper left), III (upper right) IV (lower right) and the next image shows the top of the pcb with the ziff socket. The ziff socket holds the IR array in place on the board.
