| Ink jet printers can be found in nearly every home
and
office. These devices, which revolutionized,
desktop printing, rely on disposable cartridges to dispense ink in a highly-controlled
manner. These cartridges generate
a significant amount of heat which must be dissipated in order to ensure problem-free
operations. Lap Tech Industries was approached by the leading
international supplier of heat sinks for ink jet cartridges. This company needed a supplier that could
produce large quantities of heat sinks, but still maintain sub-micron
tolerances for parallelism, flatness and thickness. The challenge was especially difficult because the
heat sinks are made of ceramic, but are very thin. This made the parts prone to micro-fractures or even breaking
if the finishing process produced too much stress. Lap
Tech engineers used their decades of finishing experience to develop
a process which combined fine grinding / flat honing to achieve and
exceed all key tolerances. Custom part carriers
were constructed to ensure that each components was held firmly in
place throughout the process, providing the stability needed to avoid
stress on the parts. In addition, the proper oils where selected
to lubricate the parts during the finishing process, while minimizing
absorption by the ceramic's porous surface. Lap Tech now enjoys a preferred position with the
customer and makes nearly 4 million heat sinks per year. Do you have demanding, high-volume finishing requirements
for your electronics application? Call
