A method and apparatus suitable for forming hermetic electrical feedthroughs in a ceramic sheet having a thickness of ≦40 mils. More particularly, the method yields an apparatus including a hermetic electrical feedthrough which is both biocompatible and electrochemically stable and suitable for implantation in a patient's body. The method involves:(a) providing an unfired, ceramic sheet having a thickness of ≦40 mils and preferably comprising >99% aluminum oxide;(b) forming multiple blind holes in said sheet;(c) inserting solid wires, preferably of platinum, in said holes;(d) firing the assembly of sheet and wires to a temperature sufficient to sinter the sheet material but insufficient to melt the wires; and(e) removing sufficient material from the sheet lower surface so that the lower ends of said wires are flush with the finished sheet lower surface.

In a hard disk drive (HDD) or an electronic apparatus in which the HDD is wrapped with a foam resin sheet with a noise absorption effect and a metal outer casing to thereby damp noise, a sub-assembly wrapping body incorporating therein the HDD wrapped with a wrapping body composed of a slippery film sheet with foam resin sheets attached thereto is mounted into the metal outer casing through the slippery surface of the slippery film sheet. In order to insulate a noise generated from a recording and reproducing drive apparatus such as the HDD, the system for use with the HDD and the electronic apparatus can simplify the assembly process required when the HDD is loaded into the outer casing serving as a noise insulation box through a noise absorption member.

The present invention relates to a smart junction box for a solar cell module, and provides a smart junction box for a solar cell module which enables an operator to easily connect and separate ribbon cables using the operation of the levers of pressing units, thereby being able to improve the contact stability of ribbon cables, and which has a heat sink structure, thereby effectively emitting the heat generated by the ribbon cables and the diodes to the outside. For this purpose, the smart junction box for a solar cell module of the present invention includes bus bars for transmitting electricity flowing from ribbon cables; and pressing units for selectively fastening and separating the ribbon cables located on contact portions of the bus bars depending on whether both ends of the lever projected by the manipulation of an operator are inserted into recesses formed in a body.

A feedthrough terminal pin assembly includes an outer ferrule hermetically sealed through a braze joint to an insulator seated within the ferrule is described. The insulator is also hermetically brazed to at least one terminal pin. The terminal pin is provided with a braze retention structure such as an annular groove that prevents braze material from filleting past the groove. Similarly, either the ferrule or the insulator is provided with a retention structure such as an annular groove that prevents braze material spill out from the insulator / ferrule interface. In that manner, the braze retention structures keep braze material from accumulating in unwanted areas where it could adversely affect hermeticity as well as proper attachment of an EMI filter to the feedthrough assembly.

A circuit card assembly and a method for manufacturing the circuit card assembly are disclosed. The circuit card assembly includes a printed wiring board with electronic components bonded thereto. The printed wiring board and electronic components are placed in an outer shell made of lightweight stiff material. The spaces or voids between the outer shell and the printed wiring board and the electronic components are filled with lightweight filling material and thermal filler material. The outer shell and the filling material provide increased rigidity to the electronic components and the thermal filler material increases heat transfer from a given electronic component to outside the circuit card assembly.

An electronic sign having slotted frame cabinets whereby each slotted frame cabinet can conveniently be attached to one or more vertically or horizontally positioned adjacent slotted frame cabinets by using connecting components which are generally located around the periphery of one or more slotted frame cabinets. Connecting components including splice bars, splice plates, and mounting clamps are aligned in, positioned along and secured to backing bars which are co-located in backing bar slots in one or more of the slotted frame cabinets. Lift eyes can be variably located in one or more lift eye slots. The use of externally located connecting components, which do not extend through the cabinetry, minimize the entry of environmental elements into the interior of the electronic sign. Multiple slotted frame cabinets can be connected without the removal of LED display panels.
