Figure 2
Substrate behavior with exposure to water. (a) Illustration showing coil how test film (yellow) is clamped into copper and acrylic testing rig to measure coil Q and resonant frequency. Film is removed and submerged in water for 24 hours. Finally coil film is removed from water and Q and resonant frequency are re-measured. (b) Substrate QUnloaded before and after water immersion in test rig. Error bars show range of Q measurements. (c) Resonant frequency shift for several test substrates after they are immersed in water for 24 hours. Error bars show range of frequency measured.
