Testing device for printed circuit boards
First Claim
1. A circuit board tester including:
- a test array, two sets of contact fingers arranged for travelling in a plane parallel to said test array, one set being arranged for testing a front side and the other set for testing a rear side of a circuit board to be tested, two contact fingers forming a probe pair as a component of a test current circuit;
a controller for positioning said contact fingers on circuit board test points of circuit boards to be tested, said circuit boards being insertable into said tester simultaneously during a test procedure;
arranged between said two sets of contact fingers is a holder for holding the circuit boards to be tested, wherein the holder has portions for accommodating at least two circuit boards to be tested, at least one of said circuit boards to be tested being insertable in said holder with its front side, and the other circuit board to be tested with its rear side, facing one of said two sets of contact fingers, and said controller is configured such that with both sets of contact fingers the circuit board test points on both the front and rear sides of said circuit board to be tested can be contacted during a test procedure.

20. A circuit board tester, comprising:
-
holder for holding at least two circuit boards to be tested;
at least two sets of contact fingers being arranged on opposed sides of the holder to thereby test both sides of the at least two circuit boards; and
a controller for positioning said contact fingers on circuit board test points of the circuit boards to be tested;
wherein the holder has portions for accommodating the at least two circuit boards such that one of the circuit boards is held in front side up orientation and the other one of the circuit boards is held in a rear side up orientation.

21. A method for the testing of circuit boards, comprising:
-
inserting a first circuit board into a holder in a frontside up orientation;
inserting a second circuit board into the holder in a backside up orientation; and
contacting circuit board test points to test the circuit boards with a first set of contact fingers located on a first side of the holder while contacting circuit board test points to test the circuit boards with a second set of contact fingers located on a second side of the holder.
