Title: Innovator Spotlight on May Fong-Ho: Pioneering Ink-Cooled Thermal Ink Jet Printheads

Introduction

May Fong-Ho, a distinguished inventor based in La Mesa, CA, has made significant contributions to the field of printing technology. With two patents to her name, she has demonstrated a remarkable capacity for innovation within the industry.

Latest Patents

Fong-Ho's most recent patent involves an ink-cooled thermal ink jet printhead. This inventive system features an efficient heat exchanger located on the back side of the printhead, which eliminates the need for traditional heat sinks. In this design, all ink directed to the firing chamber passes through the heat exchanger, where the geometry is meticulously selected to ensure nearly all residual heat absorbed by the printhead substrate is transferred to the ink. Remarkably, the system maintains a low pressure drop for the ink flow, which does not significantly impede the refill rate of the firing chambers. The heat exchanger's minimal thermal mass contributes toward a significantly reduced warm-up time, allowing the printhead to be ready for operation in a fraction of a second.
