摘要:
A sensor package apparatus includes a lead frame substrate that supports one or more electrical components, which are connected to and located on the lead frame substrate. A plurality of wire bonds are also provided, which electrically connect the electrical components to the lead frame substrate, wherein the lead frame substrate is encapsulated by a thermoset plastic to protect the plurality of wire bonds and at least one electrical component, thereby providing a sensor package apparatus comprising the lead frame substrate, the electrical component(s), and the wire bonds, while eliminating a need for a Printed Circuit Board (PCB) or a ceramic substrate in place of the lead frame substrate as a part of the sensor package apparatus. A conductive epoxy can also be provided for maintaining a connection of the electrical component(s) to the lead frame substrate. The electrical components can constitute, for example, an IC chip and/or a sensing element (e.g., a magnetoresistive component) or sense die.
