Not exactly normal, I don't think. Though I have seen similar in the CM world. I can't think of a way to remove that overplating, either. If you can't reject the boards outright, then you might be looking at some touch up work, should bridging hap

Restoration of the fluxing properties? Can't see adding a liquid flux to a solder paste (assumed expired shelf life) in order to "restore" anything. If the volatiles in the original paste are gone, then adding more carriers and volatiles will not pr

A little more heat energy to get them to the optimal temperature during reflow, but a side benefit of less warpage due to the more even spread of heat through the device during the heating. Drill the board and do your TCs and profiling as normal. Th

Jim, Thank you for the input. Could you please check your standard filter pore size? A model number would be valuable. How many shop volumes (in cubic meters) do you pump per hour? Customer is seriously thinking over installing AC system similar to

We're located in New Zealand running an older Fuji pick-and-place machine that uses long rubber conveyers about 1/8" diameter and 8 feet long to move the PCB through the machine. The ones on our machine are old and keep breaking. We've been repair
