Repeatability on all surfaces of ±0.0003” (± 7 micron)
Locating the substrate surface is a very critical aspect of precision dispensing. For some applications the needle must be positioned 0.0010” to 0.0015” (25 to 38µ) above the surface. Contact surface sensing is the most versatile and reliable method of surface sensing.
Contact surface sensor is not subject to surface textures or colors like a laser. A laser’s repeatability is reliant on the consistency of a reflected beam; surface textures and colors affect that reflectivity, altering the laser feedback from substrate type to substrate type.
The probe tip has a substrate contact area of 0.015” (380µ) in diameter. The tip may be customized for specific applications, either with a larger or smaller diameter probe.
