    • A calibratable voltage divider made by thin-film or thick-film technology formed by a flat film is an ohmic voltage divider resistor connected to have current flow through it. At least one tap is provided to tap off a desired divider voltage. The ohmic voltage divider resistor includes a single, coherent first resistance zone (10), which has one area for supplying current and another for taking current away, each being connected with a respective connection conductor (11, 12). The tap is made in the form of a second resistance zone (13) connected with the first resistance zone (10) between the current supply, and current drainage areas, and a take-off electrode (14) is attached to the second resistance zone (13). As needed, one or two cuts (16, 17), which intersect the equipotential lines are made to partially separate the second resistance (13) from the resistor (10) zone extended far enough that the potential attains the desired value at the take-off electrode (14) of the tap. The cut is so placed with respect to the coherent resistance zone that its length, or extent, hardly affects the resistance of the coherent zone between the current supply and drainage areas.

    • The holder (1) for an electronic component (20), especially a hybrid module, is preferably a unitary plastic element having an elongated base plate (2) formed with openings (14) therein to permit insertion of terminal pins or lugs (21) projecting from the component therethrough. Two holder arms (30) project from the base plate, the holder arms having module support portions (3) and oppositely projecting posts (4). The posts fit into receiving openings (26, 27) of a printed circuit board, which receiving openings having a spacing (S) which is greater than the distance (D) between the posts so that, upon insertion of the posts in the openings the arms (30) will tilt towards each other, thus clamping a module, typically in card or board form, between the module support (3) of the arms. The holder can also form a transport holder for the module, by forming, for example, in the module a notch spaced from the upper edge, and engaging the notch (22) with a projecting rim (9) formed on the upper ends of the support portions (3) of the arms, the notch being so spaced that the terminal lugs or pins (21) then just fit into the openings (14) in the base plate, thereby protecting the pins against damage.
    • 用于电子部件(20)的特别是混合模块的保持器(1)优选地是具有在其中形成有开口(14)的细长底板(2)的整体塑料元件,以允许插入端子销或凸耳(21) 从部件突出。 两个保持臂(30)从基板突出,保持臂具有模块支撑部分(3)和相对突出的支柱(4)。 所述柱装配到印刷电路板的接收开口(26,27)中,所述接收开口(26,27)接收具有大于所述柱之间的距离(D)的间隔(S)的开口,使得当在所述开口中插入所述柱时, 臂(30)将彼此倾斜,从而将模块(通常以卡或板的形式)夹在臂的模块支撑件(3)之间。 保持器还可以通过在模块中形成与上边缘间隔开的凹口并且与凹口(22)接合形成在模具的上端的突出边缘(9),从而形成用于模块的输送保持器 所述臂的支撑部分(3),所述凹口间隔开,使得所述端子凸耳或销(21)刚刚配合到所述基板中的开口(14)中,从而保护所述销不受损坏。

    • A process for producing a ceramic multilayer substrate, particularly an LTCC substrate, in which printed circuit traces and plated contactings are produced in a printing process on a plurality of green ceramic foils using a conductive paste which contains a wax as a printing carrier and is free of highly volatile solvents, and the green ceramic foils subsequently being arranged in a stack one upon the other and fired. The otherwise customary, time-consuming drying of the green ceramic foils for the vaporization of the utilized solvent is eliminated. The foils can be stacked and fired immediately after the printing of the printed circuit traces and plated contactings. Furthermore, shrinkage of the printed circuit traces and the green ceramic foils before the firing is avoided, thereby decisively improving the precision of the produced ceramic multilayer substrates.
