Notes:

Maximum contact resistance with 0.2mm compression (contact resistance will decrease with increased compression). Measurements

were taken using 0.4mm square electrodes. The 0.75mm value is interpolated from a test of 0.5mm, 1mm, and 2.0mm elastomers.

The test used 0.5mm wide Au plated electrodes with a 0.5mm gap between them. 500VDC was used with a 1mm thick elastomer

compressed 0.35mm.

Measurements were taken with a flat gold plated electrode. The 0.75mm value is interpolated from a test of several elastomer

thicknesses ranging from 0.1mm to 2.0mm.

This is a conservative estimate based on 1mm thick elastomer test results with test probes spaced at 0.5mm.

Measurements were taken with test probes at 0.5mm pitch. The 0.75mm value is interpolated from a test of several elastomer

thicknesses ranging from 0.1mm to 2.0mm.

The wires are on a 0.1x0.1mm grid. Multiple wires make contact per solder ball based on its size and depth of penetration.
