Hi Teo - The use of a vibrating mechanism on the reflow oven rail is a poor
substitute for fixing the real cause of skewed and shifted components! I
suggest focusing on why the components are being presented to the reflow
oven in a skewed position (poor placement?!) and solving that issue.
Vibrating a solder joint that is molten and/or in the process of
solidification can result in a number of solder joint wetting issues.

Subject:  [TN] vibrating mechanism on reflow oven rail




One of our supervisors attached a vibrating mechanism to the rail on the
reflow
oven.  This helped align some skewed and shifted components.   I have never
heard of this before.  It appears to work, but there are some issues with
finding optimal frequencies, etc.

Is anyone using any technology similar to this?
