A method of forming an overmolded plastic structure on a metallic plate includes first bonding a component to the metallic plate. The component is bonded with an adhesive that adheres it to the metallic plate. A plastic structure is formed over at least a portion of the component and the metallic plate and the plastic structure primarily adheres to the component. The component can be a set of metallic signal conductors that are used to route electrical signals across the metallic plate and the adhesive can be used to electrically insulate the signal conductors from the metallic plate.

A package base includes a package base body and a bonding metal layer provided in a frame shape or a ring shape in plan view on the package base body, wherein the bonding metal layer contains a Ti—Ag—Cu-containing alloy and a metal belonging to Group 6 in the periodic table.

An array of electrical components may be mounted in openings in an electronic device housing. The housing may have a cylindrical shape or other curved shape. A support structure such as a hollow cylindrical tube may be mounted within the interior of the housing. The electrical components may have terminals that mate with corresponding contacts on a flexible printed circuit. Interconnect paths on the flexible printed circuit may be used to route signals for the electrical components. The flexible printed circuit may be wrapped into the shape of a cylindrical tube and may be mounted on an interior surface of the cylindrical housing or on the exterior surface of the support structure.
