Grainy solder is a process indicator. It is not necessarily a defect. Search fine SMTnet Archives for background.

This condition could also be caused by gold plated pads.

Cool! What will they think of next! Maybe solder with no lead or parts with thousands of connections you cant see!

The XRAY looked okay with minimum voids throughout. Customer reports insufficient contact causing intermitten failures.

MPM is superior...specially the UP2000. Wider Field of View offers faster 2D recognition process.
