    摘要： A method for the production of printed circuit boards comprises the steps of producing recesses (2, 3, 4, 5) and/or through holes (2a) in a substrate (1) made from insulating material, in particular by means of laser-ablation, wherein the recesses and/or through holes correspond to the desired structure of conductive tracks and/or plated through holes; introducing a base layer (6) on one or both sides of the substrate (1); and introducing a conductive material (7) onto the base layer (6) which is catalytic and/or activating relative to the conductive material (7). The base layer (6) is selectively removed from the substrate (1), except in the recesses and/or in the through holes, by means of laser-ablation prior to introduction of the conductive material (7). Processing of the surface of the conductive material, the base layer or of the substrate is no longer necessary.

    摘要： An adapter arrangement for electrically testing printed circuit boards consists of two probe adapters with a uniform grid separation of the probes and two translator foils on whose sides facing the probe adapters there are contact areas with the pitch of the probe adapter. On the sides facing the printed circuit board, the arrangement of the contact areas and the contact points located thereon is the same as the grid on the printed circuit board under test. Between the translator foils a vacuum is generated with the help of rubber seals, a through hole, a valve and a suction hose. This vacuum creates a rigid package which permits good contact with the probes on both sides. The inserted support layers, which can be conventional printed circuit boards, prevent the translator foils from buckling. The various types of extremely complex printed circuit board can be electrically tested rapidly and cheaply using this arrangement. The arrangement can be employed on both double-sided and one-sided electrical test installations.

    摘要翻译： 用于电测试印刷电路板的适配器装置由两个探针适配器组成，两个探头适配器具有均匀的探针间隔格，并且两个翻转箔在其两侧面向探针适配器的位置处具有与探头适配器的间距的接触区域。 在面向印刷电路板的一侧，接触区域和位于其上的接触点的布置与被测印刷电路板上的格栅相同。 在翻译器箔之间，借助橡胶密封件，通孔，阀门和抽吸软管产生真空。 这种真空产生了一个刚性的包装，可以在两侧与探头良好的接触。 插入的支撑层，其可以是常规的印刷电路板，防止转印箔弯曲。 使用这种布置，可以快速且便宜地对各种类型的非常复杂的印刷电路板进行电测试。 该装置可以用于双面和单面电气测试装置。
