Electron beam technology can also be used for drilling and perforation in a micro range. This process is called electron beam drilling (EB drilling) or micro perforation. In this process, a focused electron beam is used to create precise holes in thin materials, typically with a thickness of less than 50 µm.
The key advantage of EB drilling is its ability to create high-quality and precise holes with a diameter as small as a few microns. The process can also be performed without the need for contact with the material, which eliminates the risk of damage or contamination. FOCUS electron beam welding machines use a highly focused electron beam (spot size below 50 µm), which allows for precise control over the drilling process. This makes it possible to create holes with diameters as small as a few microns (depends on the thickness of the parts), with a high level of accuracy and repeatability.
