Possibly the components have been re-taped in that particular reel, with only electrical function in mind? Hard to see a nozzle causing a flip, and I am thinking if your feeders are vibrating bad enough to flip the components in the tape, that you

As has been mentioned, it's likely that the component is moving in the tape, and flipping over. It is not likely that the pick/place operation is causing this. What I haven't seen mentioned is that there is an acceptability criteria in IPC for inve

If you are using vib. feeders than the component may be flipped length wise by the following components. Components should be landing with the leads on the right side but upside down. If you are using tape feeders the component may be flipped sideway

Check the pick postion in the feeder. If the nozzle is picking at the edge of the component, it could flip it. BTW what kind of machine are you using? Stephen Olan

Most likely a feeder that has a rough advance. This can cause the part to flip in the tape before the nozzle gets it. Jerry

Hi All, We are not using a Vib. bowl feeder, or stick feeder, these parts are on a reel. The pick & place machine we are using is a Panasonic brand YV100X, its a single head with 8 nozzles. What we are finding is that the component package size is

Perhaps neither. I assume the part is T&R. It's flipping inside the tape before placement. I don't know how the nozzle could be doing it. There could be excess vibration on the feeder which is causing the part to flip. Just a thought.

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

Do you mean that pick up z height is taught too deep thats why it can possibly flip the next chip. I will check our machine if have the same setting as yours. Thank you for this thought.

I do not know the Juki machines, but on my Essemtec I need to turn on the vac after the nozzle is down for 0402 parts. I also cannot touch/hit the current part/tape because it tends to flip the next part from the tape bounce. Then there is also the t
