  • System and method for thermal management and gradient reduction
    Publication number: 20070290702
    Abstract: A micro-spray cooling system beneficial for use in testers of electrically stimulated integrated circuit chips is disclosed. The system includes micro-spray heads disposed about a probe head, which provide a coolant flow onto the IC. A flow inducing injector is provided that directs a fluid jet onto zones where stagnation of the coolant flow is present. This reduces or eliminates any stagnation points and enhance temperature uniformity over the area of the IC.
