Abstract: An electrical device includes an electrical component encased in encasement material with leads electrically coupled to the component and extending through the encasement material for attachment to an electrical circuit. The leads include an internal region plated with solder for attachment to the component, an external region plated with solder for electrically coupling the component to a circuit board, and an intermediate region between the internal and external regions which is devoid of solder and which is positioned to be in contact with the encasement material to define an unplated interface between the lead and the encasement material. Leads having a center region devoid of solder plating may be formed by providing a lead frame, with selectively plated and punched regions of the lead frame to form the internal and external lead portions, plating the internal and external lead portions with solder and thereafter punching the center unplatted region to provide a plurality of leads having a center unplatted region. Components are thereafter electrically coupled to the solder plated internal portions of the leads on the lead frame with the leads and attached electrical components encased in an encasement material so that the encasement material is in direct contact with the unplatted center region of the leads.

Abstract: An epoxy-encased wound capacitor suitable for being surface mounted and wave soldered to electronic circuitry, e.g. circuit boards and process for making the epoxy-encased wound capacitor. The wound capacitor is formed from winding together lengths of two bilaminar ribbons. The capacitor is then cured by exposing it to ultrasonic energy according to a predefined ultrasonic profile while at substantially the same time, mechanically pressing the capacitor. Contacts are formed on the capacitor and wire leads attached. Subsequently, the capacitor is placed in a flexible, reusable plastic mold featuring lead guides for precisely spacing the leads of the capacitor. Bubble-free epoxy is poured in the molds and heat cured. The epoxy-encased capacitor, suitable for surface mounting and wave soldering, is then removed from the mold.

Abstract: A distributed resistance-capacitance component formed of windings of dielectric films having patterns of metallized layers formed thereon with margins shaped to provide a distributed resistance along the metallized layers and capacitance between the metallized layers on opposite sides of the dielectric films. Electrodes and leads are secured at opposite ends of the wound coil by metal spraying or schooping.
