A board module (401) can include a board module surface (420) and a connector (403) coupled to the board module surface, wherein the connector is coupled to provide at least one signal (112, 114) to the board module. The connector can include a connector lead surface (419) substantially perpendicular to the board module surface (420); a first row of leads (430) substantially parallel to and a first distance (451) from the board module surface extending substantially perpendicular from the connector lead surface (419) and shaped to connect substantially perpendicular to the board module surface at a second distance (452) from the connector lead surface; and a second row of leads (440) substantially parallel to and a third distance (453) from the board module surface extending substantially perpendicular from the connector lead surface (419) and shaped to connect substantially perpendicular to the board module surface (420) at a fourth distance (454) from the connector lead surface. The first distance is greater than the third distance, the second distance is less than the fourth distance, and each of the second row leads are offset from each of the first row of leads.

Abstract:
A semiconductor device has a plurality of first pads to a plurality of fourth pads laid out in a first direction, thereby forming first to fourth pad rows. The first to fourth pad rows are laid out in the named order in a second direction orthogonal to the first direction. First to fourth leads are respectively connected between the first to fourth pad rows and a semiconductor chip. A first slanted side inclined to the first direction is formed at each second pad at that corner which lies on that side of the third pad row. A second slanted side inclined to the second direction in such a way as to face the first slanted side is formed at each third pad. Each first lead has a first slanted portion provided between the first slanted side and the second slanted side and extending in a direction oblique to the first direction.
Abstract:
Integrated circuits utilizing standard commercial packaging are arranged on a printed circuit board to allow the production of 1-Gigabyte and 2-Gigabyte capacity memory modules. A first row of integrated circuits is oriented in an opposite orientation to a second row of integrated circuits. The integrated circuits in a first half of the first row and in the corresponding half of the second row are connected via a signal trace to a first register. The integrated circuits in a second half of the first row and in the corresponding half of the second row are connected to a second register. Each register processes a non-contiguous subset of the bits in each data word.

Abstract:
An electrical connector (1) straddle-mounted on an edge (20) of a printed circuit board (2) includes an insulative housing (10) having an elongated groove (11) for mating. A support subassembly (3) is inserted from the opposing side of the housing (10) to expose its portions in the groove (11). The support subassembly (3) includes two bases (30) with attached signal conductors (5) and a U-shaped ground member (4). Two parallel-arranged side portions (40) of the U-shaped ground member (4) are integrally connected via its central portion and each of them is located parallel to a row of signal conductors (5) as their ground reference. The united ground member (4) can be used to establish ground path to the printed circuit board (2) by fewer contacting legs (42) sheared therefrom and help all parts of the support subassembly (3) to be installed in the connector housing (10) at one time.

An electrical connector (1) straddle-mounted on an edge (20) of a printed circuit board (2) includes an insulative housing (10) having an elongated groove (11) for mating. A plurality of receiving channels (13) each used to receive a support subassembly (3) is formed adjacently to and communicated with the mating groove (11). The support subassembly (3) includes a base (30) with signal contacts (5) and a ground member (4) attached thereon. Every contact (5) includes an engaging end (51) exposed to the mating groove (11) and a tail end (52) extending out of the receiving channel (13) in a suspended status. And the ground member (4) includes a plurality of contacting legs (42) extending from the ground member (4) and being arranged to stagger with the tail end (52) of every contact (5) along the lengthwise of the connector (1). Several holding elements (43) are formed in a hook shape on one edge side of the ground member (4) to hook and be partially inserted into the apertures (22) formed on the housing (10) to stop further insertion of the support subassembly (3), and the holding elements (43) of the neighboring ground member (4) are inserted in the same apertures (22) so that they can establish a common ground path to reduce their needed contacting legs (42) to the printed circuit board (2).
