Patent ID: 7477066

Claim:
A universal grid composite circuit board testing tool, comprising: a probe station having a clamp base of variable installation positions, and a plurality of corresponding bores and through holes drilled on said probe station and said clamp base respectively, and a predetermined distance is formed between said bores and between said through holes; a plurality of conducting probes installed in said bores, and a first end of said each conducting probe being connected to a resilient element in said bore and a second end of said each conducting probe protruding from said bore; a plurality of long needles of variable installation positions inserted into said clamp base and electrically connected one-to-one with said conducting probes; one or more conducting wire bases connected with said conducting probe, and said each conducting wire base having a conducting wire contact point, and said each conducting wire contact point being connected separately via a plurality of electric cables to two through holes and conducting probes; when a printed circuit board of a different specification is tested, a new probe station and new conducting wire base are not necessary.
