It seems there isn't right connection between solder and solder-legs. Maybe check that the LEDs get huminidity, have some oxidation on the legs, try different solder paste, check the reflow solder profile. On the photo I can not saw properly reflowe

Hej, we have some connectors placed on our PCB. 2*30legs 0.5 After reflow we detect lifted legs in the AOI. Always on the outer corners. Is this something ye have experienced? And any possible solutions? Stuff we have tried: Checking the cop

Hej back at ya Your connectors could be warping during reflow. Find out by putting a connector on a hot plate and increasing the temperature. If so, you might get away with a simple fix of rotating the board 90* on your reflow oven conveyor. If you
