Reason for Connector drop using chuck nozzle | 12 February, 2020

Hi All,

I have pick DIMM connector using chuck nozzle. Shape data already refer to physical size. Unfortunately, connector drop during pick up, and have many dislodge. Can we understand what might be the reason ?

Hi Nizar,

Pick and Place nozzle, pick-up speed, component symmetry if it has to be rotated while picked up are just some things I would look at. See also if the trays you pick connectors up from, are programmed correctly to the machine. You can also ask the manufacturer of the pick and place machine you are using about an idea of what nozzle to use, since emails or calls are free/cheap.

Could you offer more info about component and nozzle you are using?

Hi Tommy,

Thanks for the reply.

We use chuck nozzle and grip the dimm connector body to pick up. The concern is;

we do pick up 2 same connector but different component size (height and width) due to different company.

So, we create two different shape data based on component size. However, only one is fine to pick up and another one is intermittent failing.

Hi Nizar,

Would you consider having maybe separate nozzles for two separate connectors? If they are different in size, you might have a problem there, since the nozzle you use, is only good for the one you get the nozzle for. After that, I assume you started to get the 'same' component from a different supplier.

Could you send some pictures of the two connectors? Is the surface where the nozzle grips the component the same size / surface / flatness?

Hi Tommy,

I don't have picture right now.

Surface where the nozzle grip is different width size.

Thanks for the point. As per your previous mention, I will look into the tray cavity setting and nozzle.

Many thanks.
