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

Are you worried the terminations might b oxidized? Do a dip test. If you have a solder pot carefully dip one termination of the cap into the solder. And see how well it wets. If that test doesn't satify the powers that be, then you can design a more

Not unless it's a case of "the only difference is..." What I mean by that is more than once I've been told the only difference in a new rev is one component or one change. But the truth was that was the only reason for the change, and in fact there

You could have a supplier problem. We had a similiar problem with one of our capacitor suppliers. I would suggest doing a solderability test on the component right out of the tape.

Semi conductor devices last for 5-10 years or more when in use. Since those parts are in stock and are not in use they are considered in good condition. The only concern that you got is how will you process them. We had the same problem before and it

Dear AJ, Try removing shield ,test it, verify if it would perform as the previous runs . If not, there maybe something wrong with device or as one of our collegue mentioned that there is possibilty the your customer change some components.If the

What are other testing/process step that we should do if we where to use the old date code QFPs other than solderability and baking ? What is the plating composition normally %? lead, % tin etc. I have my policy not to accept the more than 12 mont

Thanks for the hint. Managed to identify it easier with the codebook, it turned out to be a Phillips A6p Fast acting switching diode. Luckily I found a A6t (same but made in tiawan), tested to see if the forward current drop was the same and rework

(Hey Cal how you doing?) I can't resist this. You can sort of do what you're hoping for but you have to be very careful. Let the component run out and let the machine get as far as it's going to go. Then go to "Software Options", "Test commands" then
