How long is the connector?. It is far more likely you have a connector /
board coplanarity issue.

Subject: [TN] Samtec QMSS-DP Series Differential Pair Connectors

Good Afternoon,
Does anyone have any experience with the subject connectors?
I'm currently evaluating these connectors (the mate is QFSS series) for
a new application and am experiencing issues with coplanarity of the
leads resulting in random nonsoldered pins.  The coplanarity is listed
on the spec sheet as .004" (.10mm) max and I'm using a 6mil stencil with
1:1 apertures (as recommended by the mfr).
Thanks in advance for your assistance.

Steve
