Most pads have three separate insulated contacts. You solder paste, then heat gun the bottom.
These universal stars have no instructions. How do we connect the led? . Google youtube only show standard three contact base reflow.
Traced with ohm meter. . The round plus and minus, seems to be battery hookups. . The square plus minus for led. . Center for heatsinks. . However my Cree xpl contacts are on bottom of led. . Are we supposed to thermal epoxy the led star down and find contacts on side of led to solder to a jumper wire? This would be a quite inferior thermal path. But otherwise you would short the plus and minus. More importantly, it would make an optic or reflector impossible.
