I've been using the AM3352-SOM with good success as a BeagleBone White replacement.

However, one issue I've run into is the initial reliability of the 0.050" connectors. I find it is essential to spray contact cleaner onto the four connectors before installation onto my motherboard - otherwise, random pins sometimes fail to make electrical contact!

I'm using the Sullins PPPC232LFBN-RC mating connector, which is gold plated.

Are the AM3352-SOM connectors gold-plated? If not, can you switch to gold-plated ones? doesn't mention anything about plating.
