    • A method of fabricating a carrier support for integrated circuit chips to be mounted subsequently on a substrate. A flexible strip of an inextensible insulating material is provided with equidistant openings in the center of each of which a chip is to be mounted. One of the faces of this strip is covered with a conductive film, the said film is cut away to form in each opening interface conductors which overhang towards the center of the opening. Before the conductive film is cut away, the film is coated with a layer of photosensitive lacquer which is partly removed to enable the film to be laid bare in regions which, in each opening, form part of an open-centered zone which surrounds that portion of the film in which the free inner ends of the interface conductors associated with this opening are to be produced. The bared regions in this opening either consist of the whole of the said open-centered zone or else consist of those portions of the zone which are located at least at the points where the said zone is crossed by the outlines of the future interface conductors associated with this opening. A layer of synthetic resin electrodeposited on the bared regions of the film and thereafter the remaining portions of the photosensitive lacquer are removed, as a result of which there is no danger of the interface conductors resulting from the film being cut away causing short circuits when, after the chips have been mounted on their free inner ends, the conductors are cut at a short distance from the edges of each chip so that they may finally be soldered to the said substrate.
    • 一种制造随后安装在基板上的集成电路芯片的载体支架的方法。 不可伸展的绝缘材料的柔性条带在每个芯片的中心安装有等距的开口。 该带的一个表面被导电膜覆盖,所述膜被切除以在每个开口界面上形成,该导体突出到开口的中心。 在导电膜被切除之前,该膜被一层光敏漆涂覆,该层被部分地去除,以使膜能够在每个开口中形成围绕该部分的开放中心区域的一部分的区域中放置 其中与该开口相关的界面导体的自由内端将被制造。 该开口中的裸露区域由整个所述开放中心区域组成,或者由区域的至少位于所述区域与未来接口导体的轮廓相交的点处的那些部分组成 与这个开幕。 电解沉积在膜的裸露区域上的合成树脂层,然后除去感光漆漆漆的其余部分,结果是,由于薄膜被切断导致的界面导体不会导致短路, 在芯片已经安装在其自由内端上之后,导体在与每个芯片的边缘短距离处被切割,使得它们可以最终被焊接到所述基板上。
