Hi Jamyboy, I would find out from DDI what the 70% was rejected for, Could have been a repeat issue due to a scratch in artwork or something like that. I would not just jump and tell them to rebuild all until you know the facts. DDI is a very re

First thing try a different solder paste. All solder pastes are not created equal. Also if everything else on the board looks good then check the part. As far as nitrogen goes its about 4 bucket loads you need an external tank. I have seen some marg

Very good explanation.. yep.. after 4 set of vision cable and a new usb3 port, the problem solve.. seems like the purple cable were the root cause .. The 1st cable on marginal pass failed but not shown the "camera 0" error and we still can poll the
