Real-time spatial particulate mass deposition tester

摘要

The present invention is a real-time spatial particulate mass deposition tester. The tester is based on the principle that an anisotropic fill density distribution would result in an uneven particulate vertical pressure distribution on the inside face of the bottom surface of the die. Further, this uneven particulate vertical pressure distribution can be detected by placing multiple, sufficiently sensitive load cells on the inside surface at the bottom of the die, and analyzing the output signals acquired from the load cells using any suitable data acquisition system.
