  • Patent number: 11701883
    Abstract: An electronic assembly includes a substrate having a die and PCB mounted thereon. Wirebonds interconnect bond pads of the die with contact pads of the PCB, each wirebond having a first end portion bonded to a respective bond pad, an opposite second end portion bonded to a respective contact pad and an intermediate section extending between the first and second end portions. A dam encapsulant encapsulates each of the first and second end portions, a first fill encapsulant contacts the substrate and the dam encapsulant; and a second fill encapsulant overlies the first fill encapsulant. The first fill encapsulant has a lower modulus of elasticity than the second fill encapsulant and the dam encapsulant.

  • Publication number: 20230061768
    Abstract: An inkjet nozzle device includes: a bubble chamber having a heating element for generating a vapour bubble and an orifice positioned for communicating an impulse from the vapour bubble; a first inlet for supplying a first fluid to the bubble chamber; an ejection chamber having a roof defining a nozzle and an adjoining wall between the ejection chamber and the bubble chamber, the adjoining wall defining the orifice; and a second inlet for supplying a second fluid to the ejection chamber. In use, the first and second fluids form a fluidic interface at the orifice and the vapour bubble provides the impulse to the second fluid in the ejection chamber via the orifice, such that the impulse ejects the second fluid from the nozzle.
