Abstract:
An electronic component arrangement (10) includes a discrete electronic component (12) having first and second terminals (20, 22) and a centre-exposed pad (29). A substrate (14) has a first electrical conductor (32) electrically connected to the first terminal, a second electrical conductor (34) electrically connected to the second terminal, and a third electrical conductor (31). A thermally conductive element (26) is in direct thermal communication with both said centre-exposed pad of said electronic component and said third electrical conductor of said substrate.
Abstract:
A partially overmolded component (38) having a precisely defined overmolding edge (48) includes a component (44) having a protruding elongate rib (52) and the overmolding having a terminal edge abutting the protruding elongate rib. The rib defines surfaces that provide a greater area of contact between the component and an overmolding tool (24) and a more tortuous flow path to bleed-through.

Abstract:
An assembly (10) that attaches a ball grid array (BGA) packaged camera device (12) to a printed circuit board (PCB) substrate (14) is provided. The assembly (10) includes a spacer (30) between the device (12) and the substrate (14). The spacer (30) is configured to prevent excessive collapse of solder balls (26) located between the device (12) and the substrate (14) during reflow of the solder balls (26). The spacer (30) includes one of solder mask, tape, and/or legend ink.
Abstract:
An improved overmolded electronic assembly includes a backplate, a circuit substrate on the backplate, at least one electronic component mounted on the circuit substrate, conductive traces on the circuit substrate which together with the electronic component(s) defines a circuit device, an electrical connector, a metal ring on an outer side of a thermoplastic wall member of the electrical connector, and an overmold body. The metal ring circumscribes external connector pins of the electrical connector, and the overmold body together with the backplate and thermoplastic wall member of the electrical connector sealingly encase the circuit substrate and the circuit device defined on the substrate, with the overmold body having a peripheral edge in adhesive contact with the metal ring. The invention avoids delamination problems associate with similar arrangements which do not incorporate a metal ring.
