The following is some data about the performance of tungsten filament ball probes in electron microscope tests:
1. High resolution: Using a tungsten fiber ball probe can achieve higher image resolution. For example, in a transmission electron microscope, a resolution of several nanometers to tens of nanometers can be achieved.
2. Fast scanning: Due to the high current density of the tungsten wire ball probe, the sample can be scanned in a short time, thus improving the testing efficiency.
3. High contrast: Using a tungsten fiber ball probe can result in higher contrast images, which allows better resolution of different components and structures in the sample.
4. Long life: The tungsten wire ball probe has a relatively long life and can be used multiple times, reducing testing costs.
5. Easy to operate: The tungsten wire ball probe has a simple structure, is easy to install and operate, and can meet the testing needs of different types of electron microscopes.
In summary, the tungsten filament ball probe plays an important role in electron microscope testing. It can provide high-energy electron beams to excite the sample surface and generate images. The use of tungsten wire ball probes can improve image resolution, enhance the conductivity of the sample, achieve fast scanning, and adapt to a variety of test modes. These characteristics make the tungsten wire ball probe one of the important tools in electron microscope testing.
