Electric circuit boards fabrication test arrangement, includes actuator for releasing link between main- and secondary-guide slides as reaction to control signal

摘要

A test arrangement for electric circuit boards uses at least two needles (2,3) fixed on guide slides and, by linear displacement, are positioned at different test points. The main guide slides (6) are joined by a releasable link (12) to a secondary guide slide (11) to cause it move during a closed link in a similar movement as the primary guide slide (6) . A actuating element (13) is arranged to cause the release of the link between the main- and the secondary-guided slides (11), as a reaction to the control signal.
