摘要： A dimensionally stable core for use in high density chip packages is provided. The stable core is a metal core, preferably copper, having clearances formed therein. Dielectric layers are provided concurrently on top and bottom surfaces of the metal core. Metal cap layers are provided concurrently on top surfaces of the dielectric layers. Blind or through vias are then drilled through the metal cap layers and extend into the dielectric layers and clearances formed in the metal core. If an isolated metal core is provided then the vias do not extend through the clearances in the copper core. The stable core reduces material movement of the substrate and achieves uniform shrinkage from substrate to substrate during lamination processing of the chip packages. This allows each substrate to perform the same. Additionally, a plurality of chip packages having the dimensionally stable core can be bonded together to obtain a high density chip package.
摘要翻译：提供了用于高密度芯片封装的尺寸稳定的芯。稳定的芯是具有在其中形成间隙的金属芯，优选铜。电介质层同时设置在金属芯的顶表面和底表面上。金属盖层同时设置在电介质层的顶表面上。然后通过金属盖层钻出盲孔或通孔，并延伸到形成在金属芯中的电介质层和间隙中。如果提供隔离的金属芯，则通孔不延伸穿过铜芯中的间隙。稳定的芯材可降低基板的材料运动，并在芯片封装的层压处理期间实现从基板到基板的均匀收缩。这允许每个基板执行相同的操作。此外，具有尺寸稳定的芯的多个芯片封装可以结合在一起以获得高密度芯片封装。

摘要： Structure for mounting electronic devices thereon. The structure is fabricated from a plurality of substrates each having a thermally and/or electrically conductive core surrounded by a dielectric material. The substrates can be adherently placed together with the electrically conductive cores providing ground and power planes or the substrates can be mounted together with connectors electrically interconnecting adjacent substrates and spacing the adjacent substrates apart providing a space through which a fluid can flow to extract heat generated by the electronic devices mounted thereon. The conductive cores provide both power and ground planes to the structure and a means for thermally dissipating the generated heat.

摘要： An attachment surface for an implantable device has a random irregular pattern formed through a repetitive masking and chemical milling process. Surface material is removed from the implant surface without stress on the adjoining material and the process provides fully dimensional fillet radii at the base of the surface irregularities. This irregular surface is adapted to receive the ingrowth of bone material and to provide a strong anchor for that bone material. The unitary nature of the substrate and surface features provides a strong anchoring surface with is resistant to cracking or breaking. The surface is prepared through an etching process which utilizes the random application of a maskant and subsequent etching of the metallic substrate in areas unprotected by the maskant. This chemical etching process is repeated a number of times as necessitated by the nature of the irregularities required in the surface. The etching characteristics are controlled by the time, temperature and number of repetitions utilized in the etching process.

摘要： A method for constructing a feedthrough via connection and a corresponding apparatus includes a metallic plate (101), or rigidizer, preferably composed of an aluminum material. A solderable contact area (103), is located on the plate (101). This contact area (103) is preferable comprised of a copper material selectively disposed by a plasma spraying process. Next, an electrically insulating adhesive layer (105) is disposed onto the plate (101). This adhesive layer (105) has a feedthrough via (106) disposed therethrough aligned with the contact area (103). Then, a substrate (109), preferably composed of a flexible composite polyimide material, is disposed onto the adhesive layer (105). This flexible substrate (109) has a via (110) disposed therethrough with a solderable area (111) disposed thereon. Then, a quantity of solder (113) is disposed onto the solderable area (111), and the assembly (100) is heated so that the solder (113) flows into the vias (106) and (110), thereby providing an electrical connection including the solderable area (111) of the via (110), the solder (113), and the contact area (103). During this reflow step, the structure of the adhesive layer (105) acts as a soldermask preventing the solder (113) from flowing outside of an area defined by the via (106).

摘要： Disclosed is a method of fabricating a multilayer electronic circuit package. The multilayer circuit package has at least one layer that is a circuitized, polymer encapsulated metal core. According to the method of the invention a metal foil is provided for the metal core of the layer. This metal core foil may be provided as a single unit or in a continuous, roll to roll, process. The vias and through holes are drilled, etched, or punched through the metal foil. An adhesion promoter is then applied to the perforate metal foil for subsequent adhesion of polymer to the foil. The dielectric polymer is then applied to the perforate metal foil core by vapor depositing, chemical vapor depositing, spraying or electrophoretically depositing, a thermally processable dielectric polymer or precursor thereof onto exposed surfaces of the perforate metal foil including the walls of the through holes and vias. The dielectric polymer or precursor thereof is then thermally processed to form a conformal dielectric, polymeric coating on surfaces of the perforate metal foil, including the interior surfaces of the vias and through holes. This dielectric, polymeric coating may then be circuitized, and coated with an adhesive for lamination to the next adjacent layer. After lamination, one or more chips are attached to the completed package.

摘要： A process of producing a metal base laminate plate wherein the productivity and the yield are high. The process comprises the steps of applying an insulator film by powder coating to a metal plate having a through-hole formed therein to form a metal base plate, placing a film base plate having a heat resisting property in position on the metal base plate with a thermosetting adhering sheet interposed therebetween, pressurizing and heating part of a layered body consisting of the metal base plate, adhering sheet and film base plate to temporarily adhere the metal base plate and the film base plate to each other, and introducing the layered body in a predetermined orientation into a pair of pressuring and heating rollers to finally adhere the metal base plate and the film base plate to each other. When a layered body of a metal base plate and a film base plate passes the pressurizing and heating rollers, air is driven out of them. Consequently, little air bubbles remain in a metal base laminate plate produced by the process.

摘要： A method for the manufacturing of a metal core pc board which provides for manufacturing of two or three dimensional metal core pc boards of any form with or without throughplating. The manufacturing of such pc boards can occur by injection molding, injection/compressing molding or by a pressing method. High-heat resistant thermoplastics, as well as duroplastics are preferably employed as pc board materials. A metal with good thermal conductibility is used for the core. The material is selected such that the thermal expansion coefficients of the metal core and the pc board material are optimally equal. The manufacturing contains the following steps: lamination of the metal plate with a plastic foil on one or both sides; introduction of the desired hole pattern with a corresponding over dimension into the laminated metal plate; placing of such prepared metal core in an injection molding tool; and thermoforming the plastic on the laminated core over the plastic foil and simultaneously filling out the holes to a final dimension with the plastic.
摘要翻译：一种用于制造具有或不具有通孔的任何形式的二维或三维金属芯片印刷电路板的金属芯片印刷电路板的制造方法。这种印刷电路板的制造可以通过注射成型，注射/压缩成型或压制方法进行。优选使用高耐热性热塑性塑料以及硬质塑料作为印刷电路板材料。核心使用具有良好导热性的金属。选择材料使得金属芯和印刷电路板材料的热膨胀系数最佳相等。该制造包括以下步骤：金属板与塑料箔在一侧或两侧上的层叠; 将所需的具有相应尺寸的孔图案引入到层压金属板中; 将这种制备的金属芯放置在注射成型工具中; 并在塑料箔上将叠层芯上的塑料热成型，同时用塑料填充孔至最终尺寸。
