Cad rotation should not change with relation to how the part is presented to the machine. It should only depend on how the part is orientated on the PCB when the PCB is at 0 rotation. There is a seperate field to input part rotation inside a feeder.

We have struggled with this as well. Basically, we have a consistent rotation for all packages of the same type, but I don't think our rotation has anything to do with the actual rotation that the PnP equipment actually wants to see. I believe our

Genny you are right on with the differences between suppliers/packaging etc... I am a CEM and you are correct that we pay no heed to cad rotations from our customers/designers. A.V.L./manufacturers P/Ns information specifies orientations and such.

Oh dear, I tried not to respond but i couldn't help myself. Stop me if I go off into the woods. My guess, Chris, based on your fleeting reference to GF files, is that your SMT machines are Siemens Siplace. If this is so then package orientation def

Hello, I am the manager of a Drafting department and don�t pretend to know too much about the SMT process. But I am the manager of a CAD designer so I am somewhat responsible for the following issue. So since no one else around here seems to have the

Machine rotation is usually based off of component presentation. for example an SO8 can come in either tape and reel and sticks. In tape and reel the component is presented to the machine with pin one at the lower left corner while the stick will hav

I assume you are running Lead paste and that is why your parts are moving during reflow. Most probably these caps have leads that are bended in random directions(look at some parts from the bottom and observe how symmetrical the leads are). In additi

Check the top of the placing head. There are 3 screws around a piece that pops up when you push up on the nozzle. I had one once that was vibrating and causing the part to place slightly off angle. It is exposed to the vacuum used to pick the part

contact Mike Forseen at SMT research he is very knowlegable on all the older Fuji machines, i have alot of spare parts if you ever run into a jam.

Hello ! FUJI IP3 left head sometimes places component with rotation error. Vision processing SHOWS that component needs rotation Mechanical side is checked, looks fine. Also, changed servo, no effect. It happens randomly, maybe 1 part from 30. It
