Hi John- Maybe I am miss reading this but I can not see where a Screen instead of a stencil will benefit you. Is the thinking the screen is plyable enough to contour to the surface?

We usually use a pad that is the same size as the ball. And use a stencil thickness of 7+ mils. Why the teardrop? Russ

We're just now beginning to see 0402's in our designs. Can anyone make recommendations on stencil/aperture designs and print parameters? I'm seeing skips on a small number of joints on these parts. Thanks in advance, John
