LED reflow: Follow the component data sheet information to begin with. Many can stand only 1 reflow pass. Stencil aperture may require changing. The flat bottom on many of these devices will cause paste to squeeze to the center with typical openings. Treat as a thick film resistor with a different pad size. I changed one display board to reverse home plate last year, eliminating the mid chp solder balls..
