ABSTRACT:
A guidance type placement apparatus for placing and mounting integrated circuit (IC) components or devices, especially fine pitch integrated circuit devices (FPD), in aligned combination with printed circuit boards. The apparatus includes an image acquisition processing subsystem. The image acquisition subsystem is operative to generate images of at least one pair of diagonally opposed corners of the placement site and IC device from the same optical perspective.
