An assembly that attaches a ball grid array (BGA) packaged camera device to a printed circuit board (PCB) substrate is provided. The assembly includes a spacer between the device and the substrate. The spacer is configured to prevent excessive collapse of solder balls located between the device and the substrate during reflow of the solder balls. The spacer includes one of solder mask, tape, and/or legend ink.

An improved overmolded electronic assembly includes a backplate provided with a recessed edge, 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, and an overmold body that has peripheral edges that wrap around sides of the backplate and onto the edge recesses. The resulting over wrap feature eliminates delamination problems that would otherwise occur during thermal cycling of the electronic assembly, improves corrosion resistance at connector-to-backplate interfaces, and enhances securement of the printed circuit board assembly and electrical connector to the assembly.

Wrap-around overmold for electronic assembly

A partially overmolded component having a precisely defined overmolding edge includes a component having a protruding elongate rib 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 and a more tortuous flow path to bleed-through.

Overmolded electronic assembly

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.

An electronic component arrangement includes a discrete electronic component having first and second terminals and a centre-exposed pad. A substrate has a first electrical conductor electrically connected to the first terminal, a second electrical conductor electrically connected to the second terminal, and a third electrical conductor. A thermally conductive element is in direct thermal communication with both the centre-exposed pad of the electronic component and the third electrical conductor of the substrate.
