Thanks Rob, this is excelent

The video showing wave contact is not consistent and not stable from width size, make it better.

It looks like solder dross there or flux residue that not activated well. Your speed is 43cm/60s, wave width contact is 2cm, so dwell time is 2x43/60=1.43s, it's short also.

As has already been mentioned, black residue is usually either from dross or just a dirty pot, pump, baffles, etc.. I also saw that maaaany years ago in a system that used a flawed oil intermix "feature" but hopefully those systems are long gone.

We made much better contact of wave with board. There was not enough solder in bath. We increased it so wave height is higher with same pump power And now board is pushing dirty wave to the other side and board is much cleaner!

This is probably an inner plated layer of the component that did not bond well. It may be a component that either has the wrong surface finish for lead-free or can't handle the temperatures. Many times I have seen a similar-looking layer when the l

We have been producing an IMS assembly with SMT dpak's for some time. However, we recently encountered a new problem by chance - the parts can be flicked off with a finger nail. I state by chance because the solder joints are wetted and shiny with

I could not see pictures of your board - please attach one or two. So to answer your questions: 1. wave should not overflow over your board - mostly we use pallets as carriers to protect the assembly. 2. Solder dross is caused because your wave is no
