Patent ID: 8008938

Claim:
A testing system module for keeping pogo pins contacted with a printed circuit board precisely, comprising: at least one robot having a pogo pin, wherein said robot could be moved to a testing point of a surface of said printed circuit board and said pogo pin could be connected with the surface of said printed circuit board; a plurality of pressure detecting units, wherein said pressure detecting units are electrically connected to said pogo pin, for detecting a current pressure value pressed by said pogo pin on said printed circuit board, and converting said current pressure value into a pressure signal; a signal transformation unit for transforming said pressure signal from said pressure detecting unit, into a digital pressure control signal; a meter which is connected electrically with said pogo pin, and said meter is used to receive testing signals from said pogo pin; and a control system, for determining whether said pogo pin is contacted with said printed circuit board with a constant pressure; if not, commands said pogo pin to move along the Z axis according to a predetermined value.
