<strong>Test</strong> Process<br />
• Build several contactors of the same<br />
design populated with three different p<strong>in</strong>s<br />
• Measure metallurgical content of lead plat<strong>in</strong>g<br />
• Our standard p<strong>in</strong><br />
• Standard p<strong>in</strong> with a smoother micro surface<br />
• Standard p<strong>in</strong> with a surface profile that will provide a<br />
nom<strong>in</strong>al po<strong>in</strong>t scrub on the device<br />
• Plot p<strong>in</strong> resistance measurements (Mean, Variance,<br />
Median, Mode, and Range)<br />
• Measure the Kelv<strong>in</strong> contact resistance of the p<strong>in</strong>s and<br />
and its variance at six different temperatures: -40° C,<br />
-20°C, 0°C, controlled ambient (22°C), +80°C,<br />
+125°C when contact<strong>in</strong>g<br />
- 100% Sn device lead plat<strong>in</strong>g<br />
- 10% Pb/90% Sn device lead plat<strong>in</strong>g
