    Abstract: A printed circuit board (PCB) includes two layers, two signal transmission traces, and a vertical interconnect access (via). The signal transmission traces are respectively arranged on the layers. The signal transmission traces are electrically connected to each other through the via. A centerline of the via with a vertical line of the layers form an acute angle θ, the angle θ is less than cos−1[(Lv2−Lt2)/(Lv2+Lt2)]. Wherein Lt is loss of the two signal transmitting traces in a unit length, and Lv is loss of the via in a unit length.

    Abstract: A support module (1), comprising a conducting layer (2) having a trough hole (5) and a receiving surface adapted to receive a solid state light source (3) with the electrical contact pad (4) being aligned with the through hole (5). The support module (1) further comprises an electrical insulation element (8) and at least one contact pin (9), extending through the electrical insulation element (8), and protruding through the through hole (5). Furthermore, the electrical insulation element (8) comprises a channel (10) allowing access to the end of the contact pin (9) and the electrical contact pad (4) of the solid state light source (3) received by the surface of the conducting layer (2). Such a channel makes it possible to reach the end of the contact pin and the contact pad through the insulation element with a soldering tool. Thus, it is possible to attach the solid state light source on a metal surface by soldering the contact pin to the contact pad. Mounting a solid state lighting device on a metal surface is advantageous in applications requiring good heat dissipation, since the heat dissipation properties of a metal surface is better than of a printed circuit board.

    Abstract: A printed circuit board includes a first signal layer, a first reference layer, a second signal layer, and a third signal layer in that order and includes a first slanted via and a second slanted via. The first signal layer includes an parallel first transmission wire and a second transmission wire. The first and second transmission wires are coupled with each other and cooperatively constitute a first differential pair with an edge-coupled structure. The second signal layer includes a third transmission wire. The third signal layer includes a fourth transmission wire parallel to and coupled with the third transmission wire. The third and fourth transmission wires cooperatively constitute a second differential pair with a broadside-coupled structure. The first slanted via obliquely are interconnected between the first transmission wire and the third transmission wire. The second slanted via obliquely are interconnected between the second transmission wire and the fourth transmission wire.
