A vertical type test assembly with adjustable contact pressure feature for test on wafer. The test assembly having a probe head comprising a plurality of guide plates with a plurality of through holes wherein at least one the plurality of guide plates can be moved in a Z-direction. The test assembly further comprising a plurality of probe needles extending from a substrate end of the test assembly towards a distal end contacting contact pads on a wafer in operation. The guide plate moveable in the Z-direction is moved closer or away from at least one other of the plurality of guide plates in the test assembly thereby adjusting the force with which the probe needles contact the contact pads on the wafer and the substrate. This allows for easy correction of the contact force of the contact element with the wafer's test pad.
