ABSTRACT:
A probe for testing a circuit board having a plurality of test points distributed in a predetermined pattern over a main surface of the board comprises a locating member having a plurality of passages therein, the passages being distributed in a pattern corresponding substantially to the predetermined pattern. Probe elements extend in the passages respectively, the probe elements being movable independently of one another in the respective passages. Flexible conductors are connected to the probe elements. When the locating member is in confronting relationship with the main surface of the circuit board and the passages are in register with the test points and pressure is applied to the probe elements, the probe elements are brought into pressure contact with the test points.
