The first output parameter will always be the same parameter, which is locked

in the Input parameters section. Lock the relevant parameter by double-clicking its unlock

icon .



Note:

Only one parameter can be locked at a time.


  • Button height and width, Button diameter, Minimum SNR (times), Overlay metal thickness, and Cavity height/airgap – The calculated value of a specified parameter.

  • Deflection (µm) – The overlay deflection for the minimum force applied to trigger the sensor to achieve the calculated or specified SNR.

  • D IN (mm) – The sensor-coil inner diameter/diagonal.

  • D OUT (mm) – The sensor-coil outer diameter/diagonal. Always – 75 % of the referred button size.

  • Button-to-button spacing (mm) – The minimum spacing between buttons.

  • Minimum force required (N) – The minimum sensor-activation force to achieve the calculated or specified SNR. Always – 3 N.

  • Maximum sensor frequency (MHz) – The maximum sensor-drive frequency.

  • Estimated sensor inductance (µH) – The estimated effective sensor coil inductance. The estimate is based on the number of coil turns, trace width, PCB layers, PCB layers spacing.

  • Number of turns – The number of coil turns per each layer.

  • Via size (Mil) – The diameter of the through-hole pad in the multi-layer PCB.

  • Via space (Mil) – Spacing between through-hole pads and coil wire in the multi-layer PCB.
