ABSTRACT:
An apparatus for electronically testing printed circuit boards or the like includes a plurality of substantially parallel test pins for making electrical contact between resilient contact elements in an array plate or the like and contact areas on a printed circuit board. A mask plate extends at right angles to the test pins and has through-bores through which the test pins extend in a manner such that one end of each test pin projects therethrough to engage a respective contact area of a circuit board placed in a testing position. Spaced from the mask plate is an elastic plate which is substantially parallel to the mask plate and which receives test pins, which are non-yielding or rigid longitudinally, in a manner such that such pins are retained in the elastic plate due to the elasticity of the material thereof.
