Abstract
An ejector chip (e.g., a heater chip) has at least one fluid (e.g., ink) via, and an elongated actuator (e.g., a resistive heating element) between an edge of the chip and the via. The chip also has a conductive trace connected to the actuator. The chip also has a bondpad central to the length of the actuator to reduce a length of the conductive trace.
Claims17
An ejector chip comprising:
- an edge;
- a fluid via;
- an elongated actuator between the edge and the via;
- a conductive trace connected to the actuator and having a length and a width;
- and
- a bondpad central to the length of the actuator to reduce at least one of the width and the length of the conductive trace.

A heater chip comprising:
- a plurality of ink vias;
- a first array of heater resistors between adjacent ones of the ink vias;
- a first conductive trace connected to the first array and having a width and a length;
- a first bondpad along an edge of the chip and outside the length of the adjacent ones of the vias to reduce at least one of the width and the length of the first conductive trace;
- a second array of heater resistors between the edge of the chip and one of the ink vias near the edge of the chip;
- a second conductive trace connected to the second array and having a length;
- and
- a second bondpad along the edge of the chip and central to the length of the second array to minimize the length of the second conductive trace.

An ink jet print cartridge comprising:
- an ejector chip having an edge;
- an ink via in the chip;
- an elongated actuator positioned on the chip between the edge and the ink via;
- a conductive trace connected to the resistive heating element and having a length and a width;
- and
- a bondpad positioned on the chip central to the length of the actuator to reduce at least one of the width and the length of the conductive trace.
