SAMSUNG nozzles

SAMSUNG nozzles | 25 May, 2005

I have two Samsung machines running about 500 hours a month each. Placement rate is on the average 12,000 CPH between the two. The life expectancy of the nozzles used on 1206 packages seems rather short to me. It was about 2 months ago I replaced these nozzles (N08). Pick up Z height is okay and place down height is factory set using a software driven Z height. I roughly calculated about 30,240,000 components each month. Does the life expectancy of these nozzles seem reasonable?

What's going wrong with the nozzles that you have to replace? Are you running CP40 / 45 models? We have used our N08 nozzles for 5+yrs now without replacing.

They are a CP40 and CP50. The CP40 is fairly new and the 50 is fairly new but we bought it as a used piece. It is in good condition. As far as I can say everything seems set up correctly. By the sounds of your reply I should dig into this more deeply.

So what is happening to these nozzles? Are they sliding off of the compliance assy?, getting dinged? Have you contacted dynatech SMT about this yet?

The ends of the nozzles look flattened. I haven't measured the total length yet to see if it is in tolerance or not. That is for tomorrows "to do" list as well as calling tech support. When I slow the machine speed down and watch what is happening I do not see the nozzles pushing down on the components while they are still in the carrier tape.

check your clamping rails and see if you see any little wear marks, we constantly hit these clamps during placement when the parts are too close to the edge. The height of that clamp is either 4 or 6mm I beleive and the noozles will hit them on occasion. You may also want to check the height of placement, we have had to adjust ours from the factory settings due to excessive placement force.

That I can do, checking the placement height that is and the clamps. I believe my clamps are 4mm. If your nozzles have survived 5 years how many placements is that...roughly? In the billions?

It wouldn't be that many placements (billions) since we are a low volume high mix shop but we have placed 100s of thousands with the N08 for sure. We use the N045 by far the most since we seem to be an 0603 and smaller type shop (probably into the millions on this one). We have replaced the 045s on only two occasions. I would really think that they should last a year or so, I believe Samsung recommends that they be replaced every 6mos. We do see wear on the tips but we cannot relate it to any type of pick or place issue so we just use 'em till they wear out on the inside and won't stay on the compliance assy anymore. If you would like, why don't you send me an E-Mail and we could start discussing Samsung issues between us. Maybe like a users group or something.

We have a CP-40 and a CP-50 and have placed millions of 1206 parts in the last year and there is minimal wear on the N08 nozzles.
