A3101 Board Assembly 4007559-0501 Circuit Board

This circuit board was designed exactly as the manufacturer’s original circuit board. This circuit board had a design flaw that caused an area under the Berg connector to burn a hole through the board. This circuit board is part of the power supply module in the RT-131A Radar Receiver-Transmitter part number 4000763-3101.  The photo shows the comparison of newly designed circuit board on the left and the old damaged one on the right. The burnt area can be seen at several pad holes on connector P3103.
