摘要:
An integrated circuit package having metallized contact pads is provided with electrically conducting devices permanently attached to each contact pad. The devices are flexed when so attached, and are aligned and assembled onto corresponding pads of a second electrical component (e.g., a printed circuit board) to provide electrical connection between the integrated circuit package and the second electrical component.

摘要:
An area-array integrated circuit package assembly are provided with a plurality of electrically conductive connectors attached to the package I.O. pads, that are used to connect the package to a printed circuit card or other component. The connectors comprise at least two parallel conductors flexing together in the same direction, electrically insulated from each other for a portion of their length between the package and printed circuit card to provide for reduced interconnection inductance. The connection with the component contact pads can be achieved by mechanically pressing the package and circuit card together or with the use of bonding material.

摘要:
An apparatus for the removal of excess solder or contaminant, which are encountered on the surfaces of injection mold prior to the transfer of a solder on a silicon wafer. More particularly, there is provided an apparatus for the removal of excess solder, which may be present on a mold surface, without removing any solder, which is located in cavities formed in the mold, and wherein the solder is applied through an injection molded soldering process.
摘要:
A method and apparatus for forming solder bumps by molten solder deposition into cavity arrays in a substrate immediately followed by solidification of molten solder such that precise replication of cavity volumes is consistently achieved in formed solder bump arrays. Various solder filling problems, such as those caused by surface tension and oxidation effects, are overcome by a combination of narrow molten Solder dispense slots and solidification of dispensed molten solder.
摘要:
An improved structure (stand) for providing flexibility for holding and mounting components, such as microscopes and cameras, in order to eliminate disruptions from undesirable vibrations and tilting of the mounted component. The stand uses a vertical stand member, and a horizontal arm member movably positioned in both vertical and horizontal orientations relative to the stand member. Adjustable brackets and associated clamps are utilized.
