  • Trimming Of Embedded Passive Components Using Pulsed Heating
    Publication number: 20080190656
    Abstract: There is described a printed circuit board with a thermally trimmable component embedded therein. A layer of refractory insulating material is provided to provide mechanical support and chemical passivation for the thermally trimmable component. The component is trimmed by applying a sequence of heat pulses the a heating element, which could be the component itself or a separate element. A cavity may be burned in the substrate to provide thermal isolation for the thermally trimmable component.
