摘要： An interposer having one or more hollow electrical contact buttons disposed in a carrier. The interposer is formed by disposing sacrificial posts in vias of the carrier. The electrical contact buttons are formed on the sacrificial posts by a metallizing process in desired pattern using a mask. The sacrificial posts are made of a material that thermally decomposes upon application of heat without altering the carrier or the electrical contact buttons.

摘要： The present invention is directed to a structure for packaging electronic devices, such as semiconductor chips, in a three dimensional structure which permits electrical signals to propagate both horizontally and vertically. The structure is formed from a plurality of assemblies. Each assembly is formed from a substrate having disposed on at least one surface a plurality of electronic devices. Each assembly is disposed in a stack of adjacent assemblies. Between adjacent assemblies there is an electrical interconnection means electrically interconnecting each assembly. The electrical interconnection means is formed from an elastomeric interposer. The elastomeric interposer is formed from an elastomeric material having a plurality of electrical conductors extending therethrough, either in a clustered or un-clustered arrangement. The electrical interconnection means is fabricated having a plurality of apertures extending therethrough. The array of apertures corresponds to the array of electronic devices on the substrates. The aperture and electrical interconnection means is disposed over the array of electronic devices so that the electrical interconnection means is between adjacent electronic devices. The stack of assemblies is compressed thereby compressing the electrical interconnection means between adjacent assemblies. The substrate or each assembly is formed from a thermally conductive material such as diamond. A heat dissipation means is thermally connected to the edges of the substrate to extract heat generated within the structure. Methods for fabricating the electrical interconnection means as a stand alone elastomeric sheet are described. The ends of the plurality of conductors in the electrical interconnection means are fabricated so that upon compression between adjacent assemblies there is a wiping action between the conductor ends and contact locations on the adjacent assemblies to form a good electrical contact therewith.

摘要： Methods for fabricating Land Grid Array (LGA) interposer contacts that are both conducting and elastic. Also provided are LGA interposer contacts as produced by the inventive methods. Provided is LGA type which utilizes a pure unfilled elastomer button core that is covered with an electrically-conductive material that is continuous from the top surface to the bottom surface of the button structure. In order to obviate the disadvantages and drawbacks which are presently encountered in the technology pertaining to the fabrication and structure of land grid arrays using electrically-conductive interposer contacts, there is provided both methods and structure for molding elastomer buttons into premetallized LGA carrier sheets, and wherein the non-conductive elastomer buttons are surface-metallized in order to convert them into conductive electrical contacts.

摘要： A portion of compliant material includes four walls defining a slot. The slot has a relatively large cross-section end in fluid communication with a solder reservoir, and also has a relatively small cross-section end opposed to the relatively large cross-section end. The slot has a generally elongate rectangular shape when viewed in plan, with a length perpendicular to a scan direction, a width, parallel to the scan direction, associated with the relatively large cross section end, and a width, parallel to the scan direction, associated with the relatively small cross section end. The slot is configured in the portion of compliant material such that the relatively small cross-section end of the slot normally remains substantially closed, but locally opens sufficiently to dispense solder from the reservoir when under fluid pressure and locally unsupported by a workpiece. Methods of operation and fabrication are also disclosed.

摘要翻译： 柔性材料的一部分包括限定槽的四个壁。 狭槽具有与焊料储存器流体连通的相对较大的横截面端，并且还具有与相对大的横截面端相对的相对较小的横截面端。 当在平面中观察时，狭槽具有大致细长的矩形形状，其垂直于扫描方向的长度，与扫描方向平行的宽度，与相对大的横截面端相关联，并且平行于扫描方向的宽度， 与相对较小的截面端相关联。 狭槽配置在柔性材料的部分中，使得狭槽的相对小的横截面端部通常保持基本上闭合，但是当处于流体压力下并且局部地不被工件支撑时，局部开口足够地从储存器分配焊料。 还公开了操作和制造方法。

摘要： A cooling apparatus and method of fabrication are provided for facilitating removal of heat from a heat-generating electronic device. The method of fabrication includes: obtaining a solder material; disposing the solder material on a surface to be cooled; and reflowing and shaping the solder material disposed on the surface to be cooled to configure the solder material as a base with a plurality of fins extending therefrom. In addition to being in situ-configured on the surface to be cooled, the base is simultaneously metallurgically bonded to the surface to be cooled. The solder material, configured as the base with a plurality of fins extending therefrom, is a single, monolithic structure thermally attached to the surface to be cooled via the metallurgical bonding thereof to the surface to be cooled.

摘要： A portion of compliant material includes four walls defining a slot. The slot has a relatively large cross-section end in fluid communication with a solder reservoir, and also has a relatively small cross-section end opposed to the relatively large cross-section end. The slot has a generally elongate rectangular shape when viewed in plan, with a length perpendicular to a scan direction, a width, parallel to the scan direction, associated with the relatively large cross section end, and a width, parallel to the scan direction, associated with the relatively small cross section end. The slot is configured in the portion of compliant material such that the relatively small cross-section end of the slot normally remains substantially closed, but locally opens sufficiently to dispense solder from the reservoir when under fluid pressure and locally unsupported by a workpiece. Methods of operation and fabrication are also disclosed.
