Does anybody know if, or have data to support that, magnetic bracelets are bad to wear in an area that does circuit card assembly?

Add that to boards with solid solder deposit (ssd) pads and you have a perfect assembly. Teka components work great mk

Something is incorrect. Either: * Assembly dead functional and when we press BGA by thumb it works ... OR * Cross section with no voids , no solder joint crack. Turn-off the smoke machine.

Alcohol won't do much for the rosin residue, you'll have to scrub which isn't good on your QFP. Can you clean the assemblies before removal? A solvent such as Ensolve or Axarel would be effective on rosin.

What material is used to cap a via? Is it the > standard LPI Process/Material? we tent vias all the time, mostly to assist with assembly and the majority of the time outgassing is not a problem. What is the purpose in your case?

i agree, with the other fellow, check the data sheet for the part and see what it can handle otherwise hand assemble.

Baild1632: We've talked about ultrasonic cleaning of assembled boards here on SMTnet several times. Search the fine Archives to find threads like: http://www.smtnet.com/Forums/Index.cfm?CFApp=1&Message_ID=56105

Thanks Manuel. In an OEM facility, do we know what could be a good way to keep a track of how well SMT lines are catering to the requirements of the Final Assembly lines? Any thoughts?
