All of the replies have merit. Here is another one. Because the cause of the tombstoning is wetting forces that are imbalanced, and one end wets faster or more readily than the other, the 0402 lifts up on that end easily because of its low mass. Incr

Honda, Prnting Glueisn't as difficult as it sounds, as long as you have the right stuff and a good set up. It also depend's on what your going to be placing. If your just doing 0603, 0805 and 1208 than you really only need an 8 thou or 10 thou stenc
