Abstract
A method and apparatus for trimming a discrete surface-mounted component or a component integrated in a substrate including providing a trimmable structure mounted on the surface of a substrate for each component to be trimmed. In an exemplary embodiment, the component to be trimmed is a capacitor. In another exemplary embodiment, the trimmable structure is one electrode of a trimmable capacitor whose other electrode is integrated in the substrate, and the trimmable capacitor is connected in parallel with a surface mounted capacitor to be trimmed.
Claims12
An arrangement for enabling trimming of at least one of discrete components that are surface-mounted on a substrate and components that are integrated in the substrate, comprising the substrate and a trimmable structure on the surface of the substrate for each component to be trimmed, wherein trimming the trimmable structure trims the at least one discrete component.
A method of producing a substrate having at least one of discrete components that are surface-mounted on the substrate and components that are integrated in the substrate, comprising providing the substrate and providing a trimmable structure on the surface of the substrate for each component to be trimmed to enable trimming thereof, wherein trimming the trimmable structure trims the at least one discrete component.
An arrangement for trimming a discrete capacitor that is surface-mounted on a substrate, the arrangement comprising:
- a trimmable capacitor having:
- a trimmable first electrode on the surface of the substrate, and
- a second electrode integrated in the substrate,
- wherein the first and second electrodes of the trimmable capacitor are connected to respective electrodes of the surface-mounted discrete capacitor to connect the trimmable capacitor in parallel with the surface-mounted discrete capacitor.
A method of producing a substrate that enables trimming of a discrete capacitor that is surface-mounted on the substrate, the method comprising:
- providing a trimmable capacitor having a trimmable first electrode on the surface of the substrate and a second electrode integrated in the substrate;
- and
- connecting the first and second electrodes of the trimmable capacitor to respective electrodes of the surface-mounted discrete capacitor to connect the trimmable capacitor in parallel with the surface-mounted discrete capacitor.
