Elastomer ( ETI ) Connector Mating force result from silicone construction Electric path through each layer
Thousands of conductive paths in each layer
3-4 conductive layers connect to each pad
Product Issues Alignment of PCB pads (X: +/-0.2mm)
Retention of the elastomer
Balancing of resistance vs. part

Design (balancing all the variables)
Pw
Pp
Pd
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
Current Rating=1 Amp
Resistance: 0.035 mOhms
Increase either Wc or Pw to
increase
