Abstract
The contact pads of a print cartridge are formed on a flexible tape. Each of the uniformly spaced contact pads is preferably a square separated from an adjacent square by a minimum distance to provide each contact pad with a maximum area. The contact pads are arranged on the flexible tape only along the side portions of the plastic print cartridge body, where body is generally flat, to avoid the pads being located in the sunken middle portion of the body, where the sinking occurs during the injection molding process used to form the body. This improves the reliability of the interconnection between the pads and the printer electrodes.
