Do you mean that the vacuum will lift up the chip before it touches it? We are planning to evaluate a ceramic nozzle to get rid of magnetization. What is your thoughts on this? Thank you

With Essemtec software you can specify to turn on vacuum once the nozzle is down at the part. The default method is to turn on the vacuum while the nozzle is up, but starting to move down. For light/tiny parts this can have the effect of making them

Couple things here that could be the caused. Option 1: Error pass, Option 2: Vacuum release issues, Option 3: Magnetized nozzles (I have seen this occur by purchasing cheap nozzles), Option 4: Dirty Nozzles. Currently have two CP43 and one CP42 that

I have dealt with SMT Research myself as well for many years. I would rather pay for quality of a product than just something that seems cheaper. Be on the look out for steel nozzles as they will become magnetized and cuase you many problems. So if y

We have not checked the storage plate yet. I did send an email out to a couple of our other plants and discovered they too are seeing problems. The storage plate has come up in disscussions here. Since you mention it as well I think we should take a

for reject rate depends on various parameters, Part data parameters, (Body tolerance,Part pickup & transport speed etc. ) Also depend on vaccum level, ( During the PM we need to messure pickup nozzle vaccumlevel using manometer ) According to raw mat

warning - not all stainless steels are non-magnetic! Quite a few alloys are magnetic, some as highly magnetic as ordinary steel. One quick test is to demagnetize the jaws. If you can find one of the old-style Weller soldering guns with the copper

That would be easy to check. Degaus the whole nozzle not just the tip. It should take more than a week to become magnetized again. If it becomes magnetic sooner maybe degauss the head? I would also make sure your vacuum does not come on till the noz

Hi comando, If you change a camera, there are quite a lot of calibrations you need to carry out. Firstly: Did you remove the camera from the mounting bracket? If so, you'll need a special jig to mount it back on the bracket properly. You can still d

I do not have machine experience, but I think vacuum too early would be a more likely cause of chips leaping to a nozzle. Juki nozzles are made of hardened stainless and could be slightly magnetic, but the end is relatively small and would not have t
