Hi,

This happens more or less frequent, anb more often on reistors than capacitors.
When the tape is peeled back the resitors sticks to the tape due to static building up I think.
Have anyone successfully managed to get rid of this? On some reels this is so bad only everyt 4th, 5igh part stays in the pocket. I've played around with peeling time ets, we've filmed this with a slow motion camera and have verified that the part is completely settled before the tape is peeled off but still it follows the tape up.
It's almost like the plexi separators charges up the reels causing this.
any Ideas??

regards

I have seen this also, but didn't really do anything to fix it. It just seems to have gone away perhaps from increased humidity.

Check the grounding on the machine maybe. My machine shocks me fairly often from static, which doesn't surprise me that much because of lots of rubber belts. Maybe check the grounding or add a ground strap from machine to earth ground and see if it helps?

The metal spring is as close to the last opeing box as possible.
It's definately completely still when the tape is peeled back as I can set the delay to 1 second before it peelse it off, and I still see the same result.

I'm not allowed to attach a movie file, so please see the drop box link on what happens, look at W1, ignor the faulty placed springs on W2 and W3 please. HOW shall we avoid this, this is causing huge problems as often the part is sucked up in the nozzle anyway and sometimes placed since the optical inspection never fails eve if it only sees one pad etc.

If you download the movie rather than looking in dropbox you can zoom in on it to see it clearly.

We use AVX and KOA so it's not the cheapest shit in town... I think it may have to do with the plexi glass that's between the reels.
I'll test adjusting the winder speed, I've used the lift speed to make it much slower, the setting in the video is 6/12 so it's not fast.

The funny thing is that it seems to be more related to where they are placed since I've moved parts that are really bad in one slot and they work almost flawless in another slot. Resistors are much much worse than capacitors but I gues that's because the caps usually are heavier and more square so they stick harder to the slot.
This is driving us nuts. The worst part is 10k right now, and in a batch of 80 boards about 10 had all 8 resistors correctly fitted.
are there any plans on making the optical algorithms a bit better so they reject resistors if they are sideways and if it's only 1 pad rather than 2 in the shot? It's really annoying when the optical camera accepts a single square pad (toomb stoned part) and tries to place it meaning the resistor will be placed inbetween the two pads standing...

We have this working now, we had to remove all acrylic middle "inlays" and replace them with wood versions.
the plexi / acrylic plastic that comes with the table is causing this, they charge the reels up and cause the chips to pop out.
We have now successfully run several hundreds of the previously affected components without a single miss, so it's definately this.
I have not changed anything to any springs or adjusted any settings to get it from not working for mor than maybe 2-3 feeds to successfully making hundreds of feeds.

Table has always been grounded, we used between 4-5 reels per sheet, seems nearly impossilbe to ground away static without actually getting a mesh directly on to the tape. if I touched a finger on it worked as well.
This got lots worse when the AC started in the house so I suppose it's partly yearly dependant, as we only use AC's in the spring/summer here, and the humidity is removed with the AC and that causes more static. Would be a huge problem in cold weathers as well I imagine.
