T
LASERtrim
functional RF circuitry tuning. The tuning is normally
performed at a laser station integrated into the
automated assembly line at a point beyond any
operations that may significantly alter the circuit’s RF
characteristics. Tuning is performed by a computer
controlled YAG laser beam which removes or “trims”
the top electrode material of the LASERtrim
decreasing it’s capacitance. Circuit parameters such
as frequency or voltage are monitored during tuning
and fed back to the laser controller achieving extremely
precise results. Typical capacitance change in relation
to the amount of electrode removal is shown in the
graphs below.
