Wc WT

Resistance is proportional to AREA

overlap of STAX between PCB pads

R (milliohms) ~ Wc x Pw x Height

If you increase Wc:

- More area overlap of Pw

- Lower resistance proportionately

- Force rises proportionately

- Cost rises proportionately

Wc= STAX condutive width 0.50-1.00mm typ.

WT= Total STAX width (includes insulation)

Pw = Pad widthMixing Current/ Digital I/O:

H: 2.50mm, Wc: 1.00mm,

Pw=0.50mm

Resistance: 0.035 mOhms

Increase either Wc or Pw to
