Integrierschaltungsgerät mit verbesserten Pfosten für oberflächenmontiertes Gehäuse.
摘要
<p>An electronic device (10) includes a package (16) having two posts (30) suitable for insertion in PCB holes. Package (16) presents a lengthwise molding plane (32) along which the upper portion (42) and bottom portion (44) of package (16) are mated during the molding process. Posts (30) are disposed substantially exclusively in bottom portion (44) so that posts (30) are asymmetric about lengthwise molding plane (32). Thus, even if a top mold (42a) and a bottom mold (44a) are misaligned there will be no effect on the dimensional tolerance of posts (30) and thus the tolerance of post (30) can be closely matched with a PCB hole (20) tolerance to insure a snug fit. Thus, device (10) is mounted edgewise on a PCB (18) by insertion of posts (30) into PCB holes (20) so that tips (24) of lead fingers (14) can be connected to PCB (18) by surfacing-mounting techniques or the like. <IMAGE></p>
