Presently, circuit traces on non-ceramic PC boards can not be actively laser trimmed without severe damage to the laminate material. As such, when using non-ceramic PC boards, laser trimma- ble discrete components are required in order to allow active laser trimming. However, the only laser trimmable component types commercially available are resistors and chip capacitors. Many circuit designs require inductive elements and in many cases, these elements need to be adjusted for proper circuit performance. Presently, no inductive or phase shifting elements are available that are laser trimmable. This defines the need for laser trimmable inductive components.
