There is no standard as such. It's easy to see why. It's too complicated and has such a small payoff. Standoff is comprised of: * Package height * Solder thickness between the pad and the component lead * Delta of pad thickness and solder mask For p

| I have received prototype PBGA (256 pins) devices from | Motorola (actual part number = KXPC850ZT50). These parts seemed very warped on the edges. When I put the part on a plain surface, it rocks quite a bit when I press lightly on a corner. I h

We might need to open up the term "mass production" here, but I will give it a try anyway. I've seen semiconductor packaging companies in the far east where they pick up balls with a vacuum head, consisting of holes matching the pattern of the BGA p

Dave: You are spot-on right! The major hurdle is that 70 degrees C is below the boiling temperature of water. Only a near zero relative hudity chamber will cause the ingested moisture to migrate from a package. There is one facet of the 70 degree p
