You can try putting titanium stiffeners on the PCB to prevent it from warping. How thick is your stencil? More paste would give you a wider window however too much and you risk bridging. You could try over printing the pad at the heel and toe to get

The connector is so long, and has big metal parts, it will be little deformed during reflow I guess, andthe pins planarity should be critical for 200 pins. Did you measure the non wetting pins profile to see if temperature ok? And maybe you can try u

Experiencing a problem with a 208 PBGA device. I am achieving good wetting with the exception of one ( damn) pin on the outer corner.I have a really good profile but the worrying thing is that it is so inconsistant. Once this open pin failure is dete

Without further information my first guess would be lack of flux to "cut through" the ENTEK layer. Question: In X-ray is the suspect ball of equal diameter when compared to adjacent balls? If no then the volume of solder is different which would po

There is an approximate 1W dissipation and has a 2 sq in area below part on solder side as a heat sink, vias are to physically conect this solder side area to power pad, so its necessary to use an adequate amount of paste. I really don�t think it has

We place these on a few boards and have no issues with reflow or warpage. How thick is your PCB?

Despite the goodness of Dave F. and George Verboven, I was unable to find the damned single pin connector. As a last attempt, I've draw it (see the link) If somebody knows where can buy it, please help me (and sorry for to ruin the English language
