Over the past several months we have experienced intermittent problems with wave solder voids on PCBs coated with OSP. We suspect variation in the OSP application process, or oxidation of the surface due to insufficient or degraded OSP. Is there a me

Rob is right. ESD flooring is "Conductive" which means it can drain ESD from the body. But if you have an insulated shoe, it does not good, the ESD remains on the body. Now if you wear a smock, then you can rub ballons in your hair and touch any

Dissipative flooring is not really "conductive" so to speak. what it does is (supposedly)dissipate charge as it accumulates on the surface of mat. Does this mat have a ground lug on it? Responses are correct, unless you can get conductivity between

You might want to check with Six Sigma Services, they do this for a living, and might shed some light on the process. Myself, I'm comfortable re-balling a BGA, but I don't know about re-attaching columns...here's their web page: http://www.sixsigmas

Hey Brian how are you doing? We also have one of these feeders and it works great! The best feature is the being able to reverse the feed wheel to backfeed parts. Just talked to the guys at Hover-Davis yesterday and they have had feeders in service

Hi We are experiencing different failure modes between leaded and lead free through hole assemblies. The boards are PTH. In the case of lead free boards we are seeing fracturing of the component legs much earlier than we do with leaded assemblies. N

The wording in your second post re: lead vs. lead free behavior seems to contradict your first post, but I'll assume you mean that the lead free boards fail sooner during vib. testing. My question is, if this is the case, are the parts that are fai
