You don't clean contaminated gold fingers so much as you replace them. I once had the "cleaning" solution. It totally dissolved the gold fingers so that they could be replaced.

Are you talking about wave soldering process? Are you talking about foam fluxer against spray fluxer? I think that almost all new machines are using spray fluxer that moves back and forth. If that is not the question, please specify.

The only problem with non silver tin bismuth is its very prone to shock damage and components fall off,literally. Would only recommend it with Silver additions and around 1%.

When the board is populated on the second side, and after reflow, components are shifted, skewed with solder flowed on the leads of the components and not on the PCB land.

Just Curious why would you need to reduce the air speed by 80%

I agree with Evtimov. What he didn't point out is that the surface tension of the solder would vastly overwhelm any force from air flow.

For me it looks like a sales issue. Having more operators would probably not help them meet their metric. If you cannot meet or defeat a metric, switch metrics. (said tongue in cheek)
