Description

Beginning with the WiFi antenna connectors. There were two ombinations. The connectors on the board were always gold plated. There were two different vendors for the female connector used on the cable, one was gold plated and one looked tin plated.

Of the four machines with a tin on gold connector combination, there were six metal slivers in or around the ANT1 and ANT2 connectors on the board. These slivers appear to be shavings of plating material. Of the six machines using gold on gold connectors, only two very small slivers were found. These clearly caused no problems but they do have the potential to do so.
