Hi Scott, Here is another thought. Check your wave solder machine visually. Does the wave flow on both sides of the nozzle? If not, you may have some dross build-up which may be causing your problem. Generally it will only happen on the very fir

Thank you very much for sharing this information. It is difficult to gain knowledge in this area independently. I'll contact Kester for information on adjusting the flux density and which "thinner" to use since I am using their flux. I really like

Thinner: Flux thinner, NOT paint thinner We kept a spare stone in thinner in inventory. We cut PVC pipe to size, cap in one end, screw thread on the other, stone inside, filled with flux thinner and covered with a screw cap. I don't remember who we

for regular eutecticish solders, keep the pot temperature between 230�C [446�F] and 290�C [554�F]. If you polled us on our pot temperatures, we�d be all over the map, but with more lower than higher than you. High pot temperatures tend to generate

Here's a (427 page) EPA report on Solders in Electronics: A Life-Cycle Assessment http://www.epa.gov/opptintr/dfe/pubs/solder/lca/lfs-lca-final.pdf If you look at page ES-16/table ES-4 and ES-5 it appears that SAC alloys have a higher impact on the

I would be leary of a "Sucking" machine and hot liquid solder. Kester makes pellets that you put on top of the pot to seperate dross from lead. Technical Devices has a solder recovery machine Cal Agilent Technologies

With poorly cured mask: * Wave soldering: Expect to see thin wavy band of dross imbedded in the mask in the wave solder side. * Reflow soldering: Expect to see a pinto board where the two tones of mask are [1] normal color and [2] a lighter color, al
