Hi All,

I have been working with wave-solder for number of years.
However, I do not really know what make a solder joint
looked smooth and bright, and no grainy joint.

I've seen some boards made from certain contractors are
having a extreme smooth shinning joint. They are using
same RMA fluxes, foam fluxer. But we copy the same recipe
and try to duplicate the same kind of joint, it does not
work at all.

There must be something missing. I hope someone can help
to advise me how to do that.

Thanks.

Rgds,
Kong Hui Poh
