  • Patent number: 11000474
    Abstract: Electromechanical substance delivery devices are provided which implement low-power electromechanical release mechanisms for controlled delivery of substances such as drugs and medication. For example, an electromechanical device includes a substrate having a cavity formed in a surface of the substrate, a membrane disposed on the surface of the substrate covering an opening of the cavity, and a seal disposed between the membrane and the surface of the substrate. The seal surrounds the opening of the cavity, and the seal and membrane are configured to enclose the cavity and retain a substance within the cavity. An electrode structure is configured to locally heat a portion of the membrane in response to a control voltage applied to the electrode structure, and create a stress that causes a rupture in the locally heated portion of the membrane to release the substance from within the cavity.

  • Patent number: 10350713
    Abstract: A flux formulation includes an activator and a protic solvent. The activator may be glutaric acid, levulinic acid, 2-ketobutyric acid, 2-oxovaleric acid, or mixtures thereof. Suitable protic solvents include alkanediol, alkoxy propanol and alkoxy ethanol. The flux formulation may be a no-clean flux formulation that may be used in the soldering of electronic circuit board assemblies, for example, in conjunction with a support fixture having a planar back surface that minimizes vibrations during processing that might otherwise cause misalignment between a chip and a substrate prior to solder reflow.
