Vision system apparatus and method for component/pad alignment

摘要: An improved method and apparatus for the visual alignment placement of electrical components, such as lead-carrying chip members, pad pad-carrying printed circuit boards, purposes aligning, placing soldering said leads to pads. The involves supporting member vertically over member, inteposing therebetween a beam splitter cube which provides simultaneous view underside surface when viewed through stereo microscope means, interposing an adjustable polarizing filter means permits operator adjust contrast between pads, thereby facilitating proper X, Y theta vertical alignment, moving component down onto thereto.
