Abstract:
A method for placing a plurality of conductive preforms on a plurality of electronic pads, the method comprising the steps of:placing a plurality of conductive preforms with relation to a plurality of openings in at least one foil whereby the surface of the foil is treated to differ in color from the conductive preforms,holding a plurality of conductive preforms to a plurality of openings in the at least one foil by providing at least one holding force to the plurality of conductive preforms against a secondary material which covers at least a portion of the openings of the foil;applying a tacky media to at least one of the plurality of conductive preforms and the plurality of electronic pads;inspecting the plurality of conductive preforms whereby the inspection step is assisted by the color of the foil;locating the plurality of conductive preforms at a plurality of electronic pads; andplacing the plurality of conductive preforms on the plurality of electronic pads.
