s, typically for high-volume testing. The spring probes are arranged in a compact grid in the raster head so that up to 280 spring probes per square centimeter can be integrated. The rigid needles are moved to the desired contact point by the spring probes in the rigid needle adapter. Contacting pitch down to 150 μm can be tested by the movement of the rigid needles.
