Design of the (top) top copper 8 layesr PCB with 2 N-XYERS and (bottom) bottom copper with 300 pin connectors.

For testing of the prototype GEM detectors we have developed PCBS with different pad sizes like 3,4 sq mm comprising 256,512 pads and were being used. One such PCB is shown below with 256 pads and is read by 2 no of a front end board (FEB) with one N-XYTER with each FEB reading 128 channels.The one chip FEBS with one n-XYTER were developed at GSI.

PCB with 256 pads to be used with MANAS chip for testing GEM detector.
