O' Connor: Are you saying that: * You solder fine in the areas where you print paste * You solder poorly in the areas where you don't print paste Aside from that, the gold on these pads seems to be less bright than previous lots. [if that's not it

Hi, I can verify that, and we have done 2 or more reflows with prototypes, using vapor phase reflow, and because there is no oxygen, the result is good, and you cannot tell the difference between the first reflow, and the 3rd. We are getting a vap

you tell me, the customer has started to pull at some of the leads of some IC's with tweezers while de-bugging boards that had failed in the field, he was able to pull some of the leads away from the solder joints, we feel he may be over-doing it a

Well, we cannot make the cuts any deeper as then we would incur a significant amount of "bowing" at SMT placement/reflow. -Has anyone ever heard of changes in material/laminate makeup that causes this? A sort-of stronger, or more flexible tensile st

You can't tell how a machine will perform on your particular board by looking at it place parts at a trade show. Usually they demo a best case scenario (parts in a simple grid pattern, few package types, etc.) You need to supply the board data for y

It's difficult to tell anything from your picture. But playing the odds, I'd say it's not "gold corrosion." It is very difficult to corrode gold. Gold is a NOBLE metal. From Wikipedia, the free encyclopedia In chemistry, the noble metals are metals

Hi O'Conner, I hope you also tell us what Universal-GeorgeW discusses with you. It is a little strange seeing his name on this list and his phone number. Gee I can give you his email address but won't.. Again distance engineering is tough. I woul
