Hi All, Need your advice / help. We have assembleon pick-and-place machines and we got some pick-up issues on certain LED's that are Dome Type. The LED's get off from the tape pocket during feeding due to the dome of the LED sticks on the tape surfa

I didn't mean where the vision looks. I meant where the nozzle meets the component. I"ve seen a slight doming of these components. Although now that I think of it, Fugi nozzles would be less affected than some other machine nozzles. Assumming a syme

We have been having problems placing a domed LED with a Mydata HYDRA. The pocket that the part comes in seems to have some slop causing the part to be picked crooked. We have been playing around with different custom tools. Has anyone had similar

You might try a no HASL spec on your fids...but shelf life may hamper copper quality. Not a pleasant situation...opertors tend to polish the fids with erasers to compensate but this leads to eraser "bits" in your equipment and your solder! Maby op

Hi Dane, if with "dome" is meant the irregularity of a HASL finish than we had a lot of problems especially like Dean mentioned with finepitch parts and circular fids. It ended up with cleaning the fids with erasers before using the boards. Later we
