depends on board finish and PCB substrate materials. If you were using OSP or silver finished bare boards the time to process is less than an ENIG or HASL finished. certain substrate material absorb more moisture than others or at a quicker rate. so

Thank's Dennis. I'm also now think in this direction. Process was adjusted and soldering are good. But one from five boards can have this effect with bubbles and strange uneven distribution of solder inside the barrel. Probably copper is too thin and

As far as hole fill, as was stated above, class 2 only requires 50% up-fill. In order to get better up-fill on the initial pass, you may need to consider more pre-heat. Also, better application of flux. Are you using a drop jet, or a spray? You

Hello: I am wondering what you all do with your flux stone at the end of the day? Do you remove the unit and store it in DI water or your thinner for the flux? Do you leave the stone in and just add your thinner to get to the correct specific gravity

We used to empty the tank on Friday and let the stone basically dry out over the weekend. That was before I got involved with it. We were constantly replacing stones. Now, we empty the flux Monday morning and replenish with new. That way the stone
