Abstract:
The invention relates to a direct electric contacting arrangement (1) having the following: a printed circuit board (2) with at least one land (3) and with a ramp (5) that is arranged in front of the land (3) in the direction of the printed circuit board edge (4), the printed circuit board (2) surface that adjoins the printed circuit board edge (4) being damage-prone up to a specified distance (s) from the edge; and a contact carrier (10) with at least one electric spring contact (11) that has a curved contact dome (12). In order to make direct electric contact, the contact carrier (10) and the printed circuit board (2) are movable on top of the other in parallel, in particular insertable into each other, until the curved contact dome (12) of the spring contact (11) rests on the land (3) after sliding up the ramp (5). According to the invention, the ramp (5) projection (h) that projects beyond the land (3) is selected such that immediately after sliding up the ramp (5), the contact dome (12) of the spring contact (10) contacts the land (3) at a distance (A) that is greater than the damage-prone distance (s) from the edge.

Even if a burr is formed on a side, a wiring substrate (1e) can be obtained that can reduce protrusion of the burr to the outside further than the portion that is the bottom of the dividing groove (2) of one main surface.
Abstract:
A connector pad (12) is provided having a base (22), a top (24) opposite the base, and tapered sidewalls (26) therebetween. The tapering minimizes stress concentrations when the connector (36) is bonded into, or on the surface of a structure. The connector pad consists of a plurality of structural load carrying plies (28) suitable for sandwiching a flat structurally integrated wiring array (20) therebetween. A plurality of plated through holes (32) formed in the connector pad (12) enable access to the wiring array therein.
Abstract:
The invention relates to a method for producing interconnections with electrically conductive cross connections between the top and the bottom part of a substrate and interconnections having such cross connections. The substrate (S1) is given a slanted, roof-shaped or convex contour (K1) in the area of at least one front face and/or in the area of at least one inner wall of a recess. After metallizing the substrate (S1), printed-board conductor-shaped cross connections (Q) are produced in the area of the above-mentioned contours (K1) simultaneously with laser structuring of printed board conductors (L) on the top part (O) and the bottom part (U) of the substrate (S1).
