This Pad Printer Base is used in the process of marking integrated circuits with logos and part numbers. A rubber compound 2 is molded onto the bottom or face of a pad base 1. Rubber compound 2 serves as the transfer mechanism for transferring the logo or part number from a marking head which has the image to be printed, engraved into the marking head. Ink has been applied to the engraving. Rubber pad 2 is brought into contact with the engraving plate and the ink is transferred onto the pad in the form of the logo and numbers. The pad then swings down and makes contact with the top of the integrated circuit package, causing a transfer of image from the rubber pad to the integrated circuit.
