An absorbent edge coating for masking tape and other masking materials is herein disclosed. When the switch is activated, power is temporarily stored in the coil and is discharged through a diode and through at least one LED when the switch is deactivated and the current flows through the LED through a first power storage element which is coupled to a second power storage element. An adhesive is deposited onto a mating surface of the MEMS device andor the mating surface of the substrate. The protective barrier is interposed between the inductor and the load, and is configured to physically isolate the inductor from the load.
