Coupling device for coupling testing circuit board of test head of an integrated circuit testing device to circuit under test, has drawing in and auxiliary frames for circuit board positioning

摘要

Coupling device for circuit boards (4, 7) comprises spindle elements on the first circuit board and a drawing in frame (6) that moves perpendicularly to the plane of the first circuit board and has spindle nuts (17) that mesh with the spindles of the first circuit board. Tightening or loosening of the nuts moves the frame closer or further away from the circuit board. An auxiliary coupling device comprises an auxiliary frame (9) that is used to couple the second circuit board to the drawing in frame.
