Custom-Drilled Microholes/Apertures

Ladd has microdrilled burr-free microholes as small as 10µm since the 1960's. Although we originally produced these microholes for electron microscope columns, they are now used in a wide variety of applications such as:

X-Ray Collimators
Light Limiting Orifices
Ion Beam Columns
Mask-making Tools
Electron Microscope Apertures

Materials -Typical metals used are platinum, molybdenum, stainless steel, tungsten, aluminum, copper and gold. Apertures 25µm and above can also be drilled in glass, quartz, silica, ceramics, porcelain, marble, jade, ruby, YAG, Silicon, sapphire and granite.

We can even drill holes in Ceramic and Glass

Some Useful Definitions:

Microhole - Generally considered to be from 10 to 350 µm in diameter.
Burr-Free - Holes are free of burrs when viewed optically at 450X. Burr-free is critical for E-Beam, X-Ray and gas flow applications.
Aspect Ratio - The aspect ratio is the ratio of depth to diameter. The ideal hole has an aspect ratio of 1:1.  We create a counterbore in thicker materials to lower the aspect ratio and provide the most burr-free hole.
