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. Conductive traces run along the flexible tape and between the contact pads to allow for a minimum separation between contact pads, thus allowing the contact pads to be made relatively large. This improves the reliability of the interconnection between the pads and the printer electrodes.
