Abstract

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.

PAD PRINTER BASE

   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.

   In the past, pad base 1 was made of wood. The wood base was not reusable. The present pad base 1 is made of aluminum, which is reusable. This results in a more precise, cost effective unit. T-slots 3 are machined into the bottom surface of pad base 1 to provide a solid foundation for molded rubber compound 2. Aluminum pad base 1 allows quick mounting to the marking head, which does not require removal of the marking head, and adjustment is made by rotating pad base 1 on its pivot point and securing two thumb screws once align- ment is achieved.

Additional savings result from the fact that pad base 1 is reusable and rubber compound 2 adheres better to aluminum than...
