    • A method for manufacturing cooling devices for mounting on semiconductor devices. These cooling devices are made from several extruded shaped section part elements. These shaped section part elements are made from an aluminum alloy and have grooves and bead strips wherein these grooves and bead strips are fitted into each other by applying pressure in a transverse direction. The outward protruding groove walls of the shaped section elements or the bead strips are pushed into the corresponding grooves of neighboring shaped section elements. These groove walls or bead strips plastically deform by bending in so that each bead strip entering its associated groove is physically locked in place. In addition wires of high purity aluminum can be inserted into these grooves before the groove walls or the bead strips are compacted into their associated grooves. Through this method the connection points become liquid proof and the connection is securely formed in the perpendicular direction.
    • 一种用于制造用于安装在半导体器件上的冷却装置的方法。 这些冷却装置由几个挤压成形的截面部件元件制成。 这些成形截面部件由铝合金制成并且具有槽和胎圈条,其中这些槽和胎圈条通过在横向方向施加压力而相互嵌合。 成形部件或胎圈条的向外突出的槽壁被推入相邻的成形部件的相应的槽中。 这些槽壁或胎圈带通过弯曲塑性变形,使得进入其相关凹槽的每个胎圈条物理锁定就位。 此外,在将槽壁或胎圈条压实成其相关联的槽之前,可以将高纯度铝的导线插入这些槽中。 通过该方法,连接点成为防液体,并且连接在垂直方向上牢固地形成。

    • A method for depositing a thermal interface onto a heat sink including the selection of a highly thixotropic compound formed into a bulk form so as to present a tip which is melted upon contact with a preheated heat sink. The tip cross section preferably corresponds to the cross section of the heat sink. Upon depressing a tip of the compound against the heat sink a resulting vacuum therebetween cooperates with the ambient air pressure to preclude migration of the melted compound beyond the exterior of the tip such that the compound is deposited on the heat sink in the desired cross section form. Upon displacement of the tip from the heat sink, the ambient air pressure precludes subsequent migration of the compound onto the heat sink precluding a build up of the deposited material thereon. The component may then be subsequently pressed against the subsequent heat sink without a deformation of the compound tip precluding a subsequent deposit. Alternatively, after cooling the heat sink with pad may be reheated to melt the thermal pad for subsequent placement of a component thereon.
    • 一种用于在散热器上沉积热界面的方法,包括选择形成为大块形式的高触变性化合物,以便呈现与预热的散热器接触时熔化的尖端。 尖端横截面优选对应于散热器的横截面。 当将化合物的尖端压靠在散热器上时,所得到的真空与环境空气压力配合,以排除熔化的化合物超出尖端的外部的迁移,使得化合物以期望的横截面形式沉积在散热器上 。 当尖端从散热器移位时,环境空气压力排除了化合物随后迁移到散热器上,排除了沉积材料在其上的积聚。 然后可以将组件随后压靠随后的散热器,而不会使化合物尖端变形,从而阻止随后的沉积。 或者,在冷却之后,可以重新加热具有焊盘的散热器以熔化热焊盘,以便随后将部件放置在其上。

    • The present invention relates a method of manufacturing a high fin density heat sink comprising the steps of: aligning a plurality of length sections side by side in a mutual parallel arrangement, said length sections having a cross-section comprising a first end portion, a second end portion and a web portion connecting said first and second end portions, said first and second end portions having a width wider then the width of the web portion; clamping the parallelly arranged length sections together, such that said first and second end portions of adjacent parallel length sections are abutting against each other; and bonding the length sections together by applying at least one friction stir welding (FSW) seam across the end portions of the parallelly arranged length sections.
