In our assumption also, nozzle is magnetized because the chip termination is made up of alloy so possibilty that when there is excessive contact between two metals there magnetic field produce, so during z up chip is magnetize on the nozzle causing i

We were and still are having problems with magnetized nozzles on the HSP 4796. The problem was found when numerous parts were thrown after being placed on pad. It appeared to be picking parts up off the board after placement. Nozzles were pulled out

We have four 4796 machines, and I have not yet seen this problem. By chance did You check to see if the Nozzle Storage Plate is magnetized? Just a thought. Hope this helps.

Any luck with the Nozzles?

We change the nozzles depending on the job. Do you have the magnetic nozzles? We upgraded to that. Usually we use the smaller ones.

Who makes the best after market Fuji nozzles ?

I think fuji and all the after market suppliers use stainless "hypo" tubing for the tips. It is made from 304 stainless which is normally nonmagnetic. In the process of forming this tubing to the hypo specs it is work hardened to 3/4 to full hardness

Make sure chips (some Resistor contain nickel,or A-42 (Fe-Ni)leads made like SOT-23, etc )some time they also are magnetized and get attracted by nozlles tips. rgds

If this is in regards to the manufacturing floor: I can remember years ago I had an Fuji IP3 + MTU4. Used square magnets to hold tray stacks square to the machine. Manufacturing manager told me they should not be used. Apparantly the magnetic fie

Are the pick up nozzles metal made (ironmagnetic material)? Some time magnetic residual on metal nozzles can generate pbm like that when chips terminations have nickel and when SOt or similar packages have terminal A42 alloy made. Time ago got pbm l

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
