Latest Patents

One of Dankelman's latest patents is the "Zero Force Heat Sink." This invention involves a heat sink that is placed in a heat transfer relationship with a substrate, such as an integrated chip or chip carrier, without imparting stressful forces to the substrate. The heat sink is connected to a frame, which is in turn connected to a printed circuit board or other suitable support. This design allows the heat sink to extend through an aperture in the frame and be coupled to the substrate's surface while remaining mechanically decoupled. The invention is particularly useful for thermally connecting large heat sinks to surface-mounted substrates using various technologies.

Another aspect of the Zero Force Heat Sink is its ability to move freely within the aperture during assembly, making it adaptable for different substrates. The frame is designed to match the thermal expansion of both the underlying support and the substrate, ensuring that the assembly can expand and contract without causing stress.
