Abstract:
The invention relates to a multifunctional printed circuit board for use as rigid/flexible or semi-flexible printed circuit board in the form of a through-hole printed circuit board or multilayer printed circuit board or flexible printed circuit board. At least one additional functional element is fastened in at least some sections on a copper foil by ultrasound or friction welding in a planar manner, thereby producing an intermetal compound. A notch is milled into said section allowing the printed circuit board to be bent like a rigid/flexible printed circuit board or semi-flexible printed circuit board. When two notches are milled, the printed circuit board can be bent twice by approximately 45° by a total of 90°. The invention also relates to a method for producing multifunctional printed circuit boards which comprise at least one additional functional element and a milled notch.

Abstract:
A mounting substrate (10) including an interconnection (12) provided on a front surface of a substrate, a lead pad (24) provided separately from the interconnection (12), on the front surface of the substrate (10) and, a lead (20) connected to the lead pad (24) by solder (22), and a connecting portion (28) that connects the interconnection (12) and the lead pad (24) after the lead (20) is connected.
Abstract:
There are disclosed printed board (5) on which electronic parts are mounted, a method for manufacturing the printed board, and a structure for connecting conductor elements (8, 8') to this printed board. The printed board includes an insulating supporting substrate (50) and at least one metallic terminal (53, 54). The supporting substrate is provided with at least one opening (51, 52) through the substrate, and the metallic terminal is fixed to the supporting substrate without protruding from the supporting substrate and bridges the opening.
Abstract:
The present invention relates to mounting an electric connector (20) onto a printed circuit board, particularly to a printed circuit board comprised of ceramic material, for instance either an LTCC substrate or an HTCC substrate. The problem addressed is one where the connector (20) tends to loosen from the substrate when the temperature varies. This is due to the difference in the coefficients of thermal expansion of the printed circuit board and the connector (20). The problem is solved with the aid of a so-called shim (10) that has a coefficient of thermal expansion between that of the printed circuit board and that of the connector. One side of the shim (10) is soldered onto the connector and the other side of the shim is soldered onto the printed circuit board. The connector (20) is therewith fastened to the printed circuit board. Shear stresses acting between the connector (20) and the printed circuit board are distributed through said board through the medium of two joints instead of one. The connector may alternatively be provided with a built-in shim.
Abstract:
A lead-free solder paste printing method is practiced with use of a metal mask having two openings which are circular or elliptical in shape by placing the metal mask (1) on a circuit board (2) having an electrode (21) formed in a predetermined pattern to join an end portion of a lead member (6), and moving a printing squeegee along the upper surface of the metal mask (1) to thereby print a lead-free solder paste on the surface of the electrode (21) on the circuit board (2). The method produces on the electrode (21) of the circuit board (2) two lead-free solder paste patterns (30a,30a) each circular or elliptical in shape and arranged in a direction in which the lead member (6) is to extend from the electrode.
