    • A ball grid array device includes a substrate having a first major surface and a second major surface. The first major surface includes leads for electrical connections. The second major surface is devoid of leads. The ball grid array device also includes a first land having a solder mask opening at the first major surface of the substrate, and a second, buried land near the first major surface of the substrate. A method for forming an electronic device includes forming an electronic circuit in a substrate, placing an input pad for an input to the electronic circuit on at least one major surface of the substrate, placing an output pad for an output from the electronic circuit on the at least one major surface of the substrate, and placing an electrically isolated pad near the at least one major surface of the substrate.

    • A screw conveyor includes a steam delivery chamber, a condensate return chamber, and a helical hollow flight. In example embodiments, the condensate return chamber is defined by an inner pipe, the steam delivery chamber is defined between the outer and inner pipes, and the helical flight extends radially from the outer pipe. The screw conveyor includes a series of heating zones, each having a “closed-loop” helical passageway formed by the hollow flight and each having a corresponding steam inlet, condensate outlet, and barrier. Steam travels into the screw conveyor, through the steam inlets, and into the helical passageways, where it condenses as it heats a material conveyed by the screw conveyor. As the screw conveyor rotates, the barriers force the condensate upward until it drains through the condensate outlets and into the condensate return chamber for removal from the screw conveyor.
    • 螺旋输送机包括蒸汽输送室,冷凝水回流室和螺旋空心飞行器。 在示例性实施例中,冷凝物返回室由内管限定,蒸汽输送室限定在外管和内管之间,螺旋形螺旋从外管径向延伸。 螺旋输送机包括一系列加热区,每个加热区具有由中空螺旋形成的每个具有相应蒸汽入口,冷凝物出口和阻挡层的“闭环”螺旋通道。 蒸汽通过蒸汽入口进入螺旋输送机,并进入螺旋通道,当螺旋输送机加热由螺旋输送机输送的材料时,蒸汽冷凝。 当螺旋输送机旋转时,障碍物将冷凝物向上推动,直到其通过冷凝物出口排出并进入冷凝水回流室,以从螺旋输送机中取出。
