The invention relates to a method for positioning at least two printed circuit boards (1a, 1b) in a housing (2) of a field device in automation engineering, wherein at least the surface of the housing is nonconductive, wherein the housing (2) has, provided in it, at least a first mounting point (3a) for mounting the first printed circuit board (1a) and a second mounting point (3b) for mounting the second printed circuit board (1b) at respective prescribed positions, wherein at least one conductor track (10) arranged in the housing (2) is provided, wherein the conductor track (10) is non-detachably connected to the housing (2), and wherein the conductor track (10) makes electrical contact between the first mounting point (3a) and the second mounting point (3b), comprising the steps of: prefabricating the printed circuit boards (1a, 1b) and prefabricating the housing (2), mounting the printed circuit boards (1a, 1b) at the mounting points (3a, 3b) of the housing (2), with the mounting of the printed circuit boards (1a, 1b) involving the first printed circuit board (1a) being put into electrical contact with the first mounting point (3a) and the second printed circuit board (1b) being put into electrical contact with the second mounting point (3b), so that the first (1a) and the second (1b) printed circuit board are put into electrical contact with one another via the at least one conductor track (10).

The present disclosure describes a network switch design that includes a vertical switch circuit board that is mounted parallel to the front panel of the network switch. The vertical circuit board supports switch chip(s) to process and forward packets and pluggable module connectors to receive pluggable optics modules that provide connections to other network switches. The pluggable module connectors are horizontally oriented to facilitate routing of electrical signal traces. The arrangement of the circuit board, switch chip(s) and pluggable module connectors achieves reduced lengths for the electrical signal traces that connect the switch chip(s) to the pluggable module connectors. The design improves cooling by providing separate airflow regions between the switch chip heatsink(s) and the optics modules.

Provided are a receptacle assembly and a circuit board in which routing of internal layer wirings is taken into consideration. Some of the plurality of first internal layer wirings 134 are drawn toward the second electrode line L2 when viewed in the depth direction Dd, and some of the plurality of second internal layer wirings 134 are drawn toward the first electrode line L1 when viewed in the depth direction Dd.
