We have been having some issues recently with a TSOP-II 54 pin, where upon second reflow the part will lift at end one, most of the time the solder will pull up with it and still connect but I still worry about strain on the component as well as it i

Hi Ameen, Did you fix it? I had the exact same problem with the same type of coil , check the images , LF solder SAC305, we have adjusted the solder apertures to the minimum solder required to have a strong joint enough to break the pad from the bo

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

It is strange that you're having issues while using the same process parameters (including stencil) that worked successfully before. It doesn't guarantee that it's not one of those parameters changing in a manner that's not apparent, but it does sugg
