The reasons could be: -The pads size are uneven. Modify the pads size. -The part has not enough time for self-centering. Check and increase TAL. -Solderpaste not melted completely. Increase peak temp. -Solderpaste does not work well. Use alternate so

Hi, I totally agree. If I purchased a machine, and a company wanted me to pay some kind of fee just to be able to purchase parts, I would go nuts. What a terrible policy. I think, and this is becoming more common, that companies are becoming so sel

Does replacing the BGA fix the problem? To be a little more blunt, is the BGA or is it the tech says it's the BGA. Beleive none of what you hear and only half of what you see. What kind of BGA is it? If it is one of those BGA's with a built in heats

The centering jaws are made out of copper, I believe...and conductive. I'd suggest that the conductivity of the copper makes it a fairly poor source of ESD damage in a component. I have observed physical damage to components from the centering jaws

Dear Collegues: We recently commissioned a laser machining center that is used on a job shop basis for a variety of customer work. Does anyone have a recommended procedure for completing a machine capability study? How about a recommendation on

I'm not completely sure what you're asking, but, I can say that I've placed these parts with MyData's and Philips machines. Pick in the center of the part, and place in the center of the outline, and the terminals should line up with the pads on the
