SOM System B2B Connector Assembly
Validation-DOE (To Ensure Time 0 No Crack)
The Samtec ADF and ADM connectors placement were shifted 0% and 15% (based on connector
pad diameter) on the X and Y-axis for both the SOM and carrier cards. The shifted connectors
were reflowed and were able to mate without any issue.
The mated connector boards were submitted for cross section testing to validate their mating
conditions. Based on the cross-section images, the connectors which shifted by 15% were able
to self-align during reflow soldering. The following photos are a cross section image of the mated
connectors. The proper contact of the female and male connector pins is achieved.
