Abstract:
Apparatus for electrical testing of a substrate having a plurality of first contact regions, comprising:a frame; a contact assembly having a plurality of second contact regions, said contact assembly being secured to the frame; a translation device secured to the frame; an alignment device carried by the translation device so that the translation device is mounted between the frame and the alignment device; and a holder, capable of holding the substrate, secured to the alignment device, wherein: (i) the alignment device is operable to cause alignment movement of the holder relative to the contact assembly so that selected ones of the first contact regions are brought into alignment with selected ones of the second contact regions; and (ii) the translation device is operable to cause translation movement, transverse to the alignment movement, of the alignment device with the holder towards the contact assembly so that a respective one of the first contact regions is brought into electrical contact with a respective second contact region.
