As long as you trust that the component vendor is honest & diligent (possibly add this to your vendor rating criterea?) In the UK we have a 'RoHS Trusted' Kitemark from the British Standards institute that distributors can apply for to show this. I

James, If you have a true MSD issue, then baking them AFTER your reflow is not going to fix the issue. I would have to agree with GS and look at trapped cleaner media (if your not No-clean) under the components, or inside connectors. If your runnin

Another thing to keep in mind are the vacuum hoses. The early models had a real problem with the vacuum hoses that connect to the back of the windmill. They would crack or wear through due to rubbing and cause a loss of vacuum which could cause your

Hi James, As far as i can see, if you reseal the bags, then storing in a dry cabinet would be unuseful (as the McDry will no longer be able to absorb moisture from the components, and the dry bag will only be as effective as the desiccant in it) i t

That would be the lightning effect, with increased humidity reducing resistance. 1500 VDC or 1500 VAC? What is the distance between the edges of the pads - i.e. not the pitch of the component, but the actual physical distance between conductors? A

How big are the parts? I've only seen a few parts that ever fell off. Double sided reflow is probably the most common these days The surface tension is powerful. I think the lower limit of temperature is what you would have to worry about with epox

Thanks Doctor - as always, you're right. I must've been typing with my mittens on. It's starting to get cold on this part of the planet these days. I wasn't blaming anyone, just trying to take a few questions marks away so "we're" left with the an

Due to spacing issue, we are considering using power bricks with tin/lead solder ball instead of PTH package. The solder ball is 40 mil diameter. Our CM suggested they do hand place since the pick and place nozzle cannot pick up and hold the part due

That is the problem I am having! Except with 3 separate manufacturers. To answer some of the other questions... Baking - diligence Stencil - as far as we can tell it is good Placement is good We are using Pb-free parts and solder, but I have see
