Dave, There is not really a �smart� or scientific way to check this but I know of easy ways and very effective ways. Fex. an easy way to check is with a 3� spatula, you hold the spatula at the same angle as the board and drag trough the wave simula

Are the pallets hot and killing the foam head as they pass over or is the air pressure on the air knife toi high travelling back along the board killing the foam. If these are OK make sure you have sufficient back flow onthe wave and you are draining

Jerry, In your initial post you give 260C as solder pot temp if you�re not using lead-free I would reduce the temp to 250C this will also reduce oxidation rate.

I am using a Novastar 12S solder wave with Kester water soluable fux 22-2425. I have used this for years without problems on an old Hollis machine. Just started using the Novastar and after fine tuning I get itermitten bridging on the front of the P

Flux foam is not affected by board or pallot. This wave is not the same as the hollis I used. The hollis wave flowed from middle to left and right side. This wave only flows to the left and its a very slow wave. Jerry

Hi Jerry, I bet you have dross build up on your wave. Are you running nitrogen? If not this could be the case. Hope this helps!

Just as I thought earlier, you have a stagnant wave. You should be able to mechanically adjust it so it flows in the same direction of your boards.

How much flux are you putting on the board when using your foam fluxer? How does this compare to your flux supplier recommendation?

Hi Jerry, Today is Friday and I assume you fired up your machine. Did you achieve any improvements? Always good know if our suggestions helped. Y�all have a great weekend, Patrick

Novastar is JUNK, that is why you cannot get repeatable results. Check the conveyor rails, you will find they are warped. Novastar uses cheap, non-machined rails. Straight from china or india. Their stuff is garbage. Best to swallow the loss and star
