Juki vs Samsung nozzles - Google Groups

Understand. I thought that maybe Pete's holder has some extremely strong spring and requires more force than Chinese version.

Don't know what you want to compare if you haven't measured the runouts of old nozzles... Don't you have an effect that the tip is swinging to the sides because of much to large diameter of the pipe holding the tip? I have this problem at 506, 507 nozzles.

Hi mark

I am using juki nozzle tip and my holder nozzle( i do it myself). I did not see any problem with nozzle runs out. ( it very small, 0.05mm)

My holder supper easy to change, and very tight for vacuum.

If you are interesting, i will provide drawing.

Hi Kevin
Runout that we see is the sum of nozzle runout and holder runout (how centerly and tight it keeps the nozzle). If you have 0.05 total then question is where it comes from, however it's quite good if doesn't grow if you rotate the nozzle in holder.
Where do you buy the nozzles?

If you have some drawing - yes pls share. If you don't but must do this, just tell me:
- what kind of magnet you use? Dimensions and type. Does it have flat or trapezoid surface touching to the nozzle?
- do you use there some oring to minimize an air leakage?

Hi Jason
I made few experiments with magnet today. Only very small and light coils were reacting on magnet touching to the opposite end of the nozzle. No problem with this in my case if I have blowing ventouries. Nothing for parts bigger from .

Thanks for that info Juha!

Yesterday I've searched about it over net. Surprising a bit that there are suppliers offering it for $10 and $25 as well, both Chinese nozzles not orig. Interesting if it goes about other factors or other sellers' profits...

It's some inspiration to the test. But not sure if I like it that the nozzle is attracted to the wall of the hole. Have you measured the runout with some sensor?

By the way, we tested today our nozzles and found that one of 10 has magnetically neutral (magnet does not attract it) black tip. All other are attracted by the magnet and attract small parts with different power. But placed longitudinally between two magnets polarised opposite, the tip has lost its magnetism and stopped to attract the parts even when connected to neodyme magnet! Tomorrow more experiments :-).

Yes, I can see your problem, the nozzle makes only good contact in the center and so the ends don't make good contact. The ends tend to curl up during reflow. There were two suggestions to solve this. 1) Let the operator push down the labels befor

Hi, I am an Engineering student doing some research on the component/nozzle interface on SMT Pick and Place machines. Could anyone tell me the force at which the nozzle hits the component as it is picked from the feeder or the placement force on a

We are placing labels using a Hoover-Davis feeder with a GSM. Anybody else out there doing this? My question is: Are you using a special nozzle for this operation?

We are using a standard nozzle Once placed, the label is not flat, the ends of the label are slightly lifted on both ends. The label is .650 x .200 Have you guys run into a similar problem?

You are right, basically our options are down to a custom nozzle. Pushing down the label is not the route that I would go with. Thanks for your input and good to hear that you guys found a way around it.

I would think that you could quite easily use 0.6mm I/D nozzles even when using a hand syringe. As you say you are only using this for larger devices to prevent them from falling off. I am sure there are very reasonably priced small compressed air un
