Indeed, stickiness of LED dome varies from batch to batch. We didn't have much success with adjusting pick&mount settings. Also, usage of other nozzle (recommendation from SMT manufacturer) didn't help. Usually, we have a good experience with similar

Hello, We are assembling a large pcb with 256 Lumex #SSL-LXA228SRC-TR31 SMT LED's on an HSP 4791. The part I'm using for the library is a modification of an existing SMT LED from the standard library. The problem is that the HSP rejects about 30% of
