Steve's homeland language. Do you all feel comfortable?
Q about 560-1200 FBGA. As you know most promise no greater than 0.2mm coplanarity across. Now, if we have a 0.2mm/inch PWB warpage and 0.15 mm solder print height , what will be the result in terms of safe solderings? It works, but I would like to toughen the inputs little bit. Outdoors boxes, global. Any experience out there?
