Abstract
An assembly station (10) is used to align termini or leads of components (16) with attachment pads on circuit boards (20) to enable the component and circuit board pads to be precisely aligned and coupled together. A dual port probe (22), which is secured to an x-y table, is provided with upper and lower viewing ports (30, 32) which respectively view the component and the circuit board. Images from the two are directed to video cameras (34, 36) and the signals therefrom are processed by a vision system (38) which compares the alignment of the pads and provides error correction signals (x, y, .theta.) to a robotic arm (12) to move component (16) and its pad or termini into alignment with the pads on the circuit board. Thereafter, the robotic arm brings the component into contact with the circuit board for soldering of the respective leads together.
