Abstract: An electronic device and process of making the device is disclosed. The device includes a multi-sided body defined by a plurality of electrode plates arranged in a stack. A resin layer is applied to both conductive and semiconductive regions of the device, and metal is plated upon terminals to create a conductive element. The device may be a varistor, thermistor, resistor, or other microelectronic component having a multi-sided body and terminal structures that are capable of receiving a resin coating. The multi-sided body has a resin coating on at least a portion of an exterior surface, the resin coating substantially preventing plating of metal onto the exterior surface of the body. One suitable resin coating that may be employed is a thermoset resin comprising a B-staged divinylsiloxane-bis(benzocyclobutene)(i.e. “BCB”) resin dissolved in mesitylene solvent.

Abstract: A very small electronic device adapted for inverted mounting to a circuit board includes a multiplicity of capacitors and resistors built on a substrate. The capacitors and resistors are interconnected so as to provide multiple RC circuits in various circuit arrangements. The multiple layers of the device are covered by an encapsulate having openings to expose terminal pads of the RC circuits. The openings are filled with solder to produce the individual terminations of the device in a ball grid array (BGA). The device saves cost and/or board space in the manufacture of larger electronic equipment through the elimination of multiple discrete components. In addition, very low inductance is achieved due to the close proximity of the device to a circuit board on which it is mounted.
