the standard 40-micrometer holes literally take up too much real estate. This led to the group's formation and goal to develop micro laser drilling capabilities. The breakthrough method involved ...

by laser drilling micro holes into high-density printed circuit boards to help provide electrical connections between stacked layers of circuits. A shorter wavelength laser can also weld copper ...

However, effusion cooling technology is difficult to manufacture. In fact this technology requires laser-drilling of thousands of tiny holes with shallow angles on a sheet metal with a thickness ...
