The power source earth strengthening board which is used for the prober for IC tester

摘要

(57) Abstract Objective On attachment board 5 power source earth strengthening bodo 2 is laid out, the Polar Orbiting Geophysical Observatory pin and the seat are used for electric jointDue to especially, the taking attaching of the Polar Orbiting Geophysical Observatory pin of power source earth strengthening board 2The ke just is changed choosing power source and the earth which correspond to the deviceIt to be possible, as for the pin other than the signal with the selector, optionally power source piIt makes the n, or earth pin. Constitution Multiple power sources are input from family board 1ru seat the attachment board 5 which has 51 - 58 and ataThe Polar Orbiting Geophysical Observatory pin 4A which inputs power source from tsuchimentobodo 5 -With 4D, Polar Orbiting Geophysical Observatory pin with the installation and removal of 4A - 4D multiple electricityOne power source is chosen from source. In addition, seat 5A - 5B holdingAttachment board pogopi for choice of 5 and power source and earthn to have 3A - 3B in every pin, the signal, power source and earth selection.
