Possible cause can be design related- if the solder land is too small. Check w/ IPC SM-782 Solder Land Design Guide Another is board finish. I have seen problems like this with Gold finished PWBs- which creates a more brittle solder joint.Another pos

Does your company use an MRP system? If so you should be able to print a report that defines assembly due dates as well as the time it takes to process each assembly. What I do is print the report at the begining of the week for everyone to work from

Interesting study. It shows no-Pb alloys having a greater negative environmental impact. I wonder if the Euros are re-thinking their no-Pb regulations? I also wonder if popular opinion and politics is at the route of our EPA's no-Pb regulations and n

I'm glad to see so much awareness of the challanges the US manufacturing industry is facing. But in problem solving you first have to realize that there is a problem before a solution can be worked out. I firmly believe that if we could convince the

I see this all the time and we are an OEM that can specify how parts are to be packaged. That being said, purchasing is always having problems finding the part in the specified packaging and end up buying it however they can get it. It's not like w

I need help understanding your problem. * What�s the difference between �e-test failure� and �total failure�? * Why do you think that an ESD induced failure would only be a �total failure�? * What if this is caused by a cracked solder connection? Yo

Good morning Dave F. I am not going to try to touchup the solder pad until I get surface analysis work done, don't want to ruin the evidence. I am getting XPS work done not XRF, XPS is X-ray Photoelectron Spectroscopy and can see very thin films of o

I have used both. The moles both do the same basic functions. Software options are a little different for each. If you're just looking for basic profiles/oven qualification, either will do a fine job. If you're wanting more in-depth details, I'd su

Dave, I would have never thought of the sheet metal box. My west coast contact, who has dealt with this type of board before, told me yesterday to go ahead and try it at this profile anyway, as the metal plating holds more heat. I was pleasantly
