If your pads are raised as you mentioned, you will reach just the tip of your tiny glue dot, which may not hold the part in place. However, you should be using two glue dots on each side of your 0402 component. See under adherence force in paste a

Make sure that your mesh conveyor drive chain is not jumping a sprocket tooth. This will cause the conveyor to "pop" and you will have skewed parts. I seriously doubt that it is your profile causing skew. It is more than likely something mechanical.

how fast are your cooling fans and/or convection fans running?

100% Power on cooling fans. Cooling fan speed can be adjusted, but convection fans can�t.

For reflow, low soak time and low peak temperatures will help reduce the number of components skewing Search the fine SMTnet Archives. For instance: http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=6071&mc=15

We are having a problem with our Heller 1800W oven with certian parts skewing. It seems that some inductors and taller Can caps are shifting around in the oven. It seems it will solder fine and than all of a sudden just be off to one side or the othe

I'm talking about NPM-dx machines, In the interface, there is an option called "Recognize by Mount Angle." Does having this option turned off mean that the machine head places the component as it picks it up? For instance, if a component on the reel

Scratches do not necessarily mean bad! Usually the forcer motor fails before a platen. The motors become weak or don't evenly distribute the supplied air, which causes them to tilt and drive into the platens. Mechanical misalignment of the VY forcer

Just had a similar phenomenon 2 days ago. May relate to your issue --- or not. Like you, I did a once over looking for mechanical obstruction & couldn't find any. Ran a thermal profile on the offending PCB & all checked out. Looked in end of oven

Magyart is on the right track. Lots of variables. Can you post a photo of the skewed part? But also, is it skewed in the paste before reflow? How many inductors are doing this per board? Lastly, indicate on the photo the direction of travel in the
