Abstract
In a system for positioning a semiconductor chip package with respect to a testing surface, the distance between the package or the leads thereof and the testing surface is monitored while the package is pushed towards the testing surface. When the distance monitored falls below a certain value, the package is pushed further by a set distance. In this manner, good contact between the leads of the package and the contacts of the testing surface is achieved without destroying the coplanarity of the leads.
