MACHINE FOR THE ELECTRIC TEST OF PRINTED CIRCUITS WITH ADJUSTABLE POSITION OF THE SOUND NEEDLES

摘要

Machine for the electric test of printed ciruits, of the type comprising a board which bears (1) a plurality of conductive needles (10) which are connectable on their reverse side with means for the analysis of the electri c parameters between one and the other needle, characterized in that: at least two coplanar needle boards and one adjacent to the other (1SS-1SD/1IS-1ID) a re used, and one board (1SS/1IS) is made movable with respect to the other (1SD/1ID), and the respective board to be checked (2) is made movable with respect to said boards (1) or vice-versa.
