US Patent:

20080197868, Aug 21, 2008

Filed:

Feb 19, 2008

Appl. No.:

12/033678

Inventors:

Troy Fossum - Becker MN, US
David Kariniemi - Maple Grove MN, US

International Classification:

G01R 31/28

US Classification:

324758

Abstract:

A circuit board tester and method that precisely aligns the probe plate and circuit board is disclosed. With a circuit board and probe plate mounting within a housing having a top and bottom, hinged together, at closure there may be slight misalignments of the two. By making one of the two plates floating, or laterally slideable with respect to each other, it is possible to make final alignment at closure. One of the two plates can be provided with a pin and the other with a pin receiving alignment block. With the lateral sideability, the pin and block can insure proper probe alignment. Additional systems for correcting misaligned pins or blocks are also disclosed.
