You say you have lots of problems with a BGA, tell us about: * Specific problems you see. * Solder paste supplier�s recommended profile. * Temperatures measured on the problem ball[s] of the BGA during reflow. When you say �u1 BGA�, what do mean? W

1 Chatter about mask opening � No BIG problems with these statements. It�s just that you may need to tailor your reflow recipe to minimize these escapees. 2 Stencil design - Any area ratio below 0.66 is going to very challenging to print, as you ca
