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.

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

Patrick I think peelback mechanics is more important than wave dynamics. :-) ...and "you can't talk to molten solder", but surfactant will listen.

what type of preheater does the novastar use and what temp. is it set on? I am also use to a hollis wave solder machine. Old and crude but works great.

Hello, thanks to everyone that reply to my previous question. I have another request: is it possible to solder polyester capacitors (case 2220) with wave soldering process? Thanks! Regards, Stefano

Dr. Lee, For lead-free wave soldering, we are recommended to use SnCu0.7, why not 0.8 or more ?? Since SnCu0.7 has eutectic melting point at 227 deg C, does it mean with more Cu or less Cu, the melting point will be higher ?? Also, in lead solderin

Jerry, If you�re sure your board has sufficient flux it must be that your slow flowing (single lambda) wave produces more oxides then the flux can handle. Due to the conveyer angle the front of the board usually has less flux then the back of the bo

Necoleta, PWB Blistering/De-lamination may not be due for Titanium finished threads / holders which is typically being used to draw high Shelf Life of Pallets and even flow across Auto Wave Soldering rails. There is also nothing to suspect on Liquid
