Thanks Dave, As always the best search engine! I have a hrd time finding what I need In the "government pages"

We agree Russ. The government information is very confusing. University types have the time, resources, and patience to figure that stuff-out [and hopefully the inclination to steer others in the correct direction].

I'm really wondering about the gloves and wipes. We also reclaim all metal and get paid but, we have to pay for the jars, wipes, tubes, etc... We always come out $ ahead so I'm really more curious than anything.

Hi all We recently have a problem with component in package 0805 (capasitor 100nF). I have noticed that after reflow soldering only one lead of the component is soldered. The second one is just laying on the PCB land. We use screen printing process

Greg: As we understand it, in your situation: * One 0805 lead solders to board properly * Another 0805 lead does not solder On the 0805 lead does not solder, there does the solder go? * On the pad * On the component lead A common solderability test

"And don't look for logic or consistancy in polital matters". No kidding? I am having a hard time trying to figure out how you go about determining your levels of waste and also where to find "hazardous material" classifications for my area. I am

I have a product with mixed in Pb free and Pb BGAs. I decide to use SnPb paste with Pb free reflow profile to make it work for both types of BGA. Do I have a reliability solder joint issue by using this method? How is your opinion on this case? Can

So, it looks like the backward compatible of BGA statement is not guarantee for solder joint reliability. It doesn�t matter what temperature and what melting sequence we have in order to avoid the solder void issue. Is Pb diffused homogeneously thr

Loctite makes a product called MP218 that works well with mixed alloys.

Yikes! Sounds like a hairy situation there. I've successfully collapsed a Pb-Free BGA (using a Sn/Pb solder paste), with a peak temperature of 220 Deg. C and Time Above SAC's Eutetic point (217) of 17 seconds. Beware of overcooking your smaller ma
