Hello Brad, I think Greg is a mind reader!! Thanks for the opportunity to give an update to the forum on SN100CL Lead Free HASL. Conversions to SN100CL HASL is occuring at a rapid pace worldwide. As of July 2006, there were over 250 HASL machines ru

Good afternoon! Typically, we normally recommend testing the pot, and adding either Sn/Ag or just Sn to keep it at bay. One nice thing about the solubility of Cu in Sn based alloys is that it should reach a theoretical upper limit of about 0.1%. I

Good morning all. We are able to offer some insight into the problem and offer a recommended reflow profile to solve this issue, but it really depends on the solder paste that you use, as different manufacturers use different boiling point solvents.

David, We have seeing this more and more in the recent weeks. In a nut shell, yes; we believe that the voids that you are seeing are from the trapped air in the via from printing over it. If you could remove the Kapton tape, this might help. Also

Good afternoon. From what it sounds like is that the solder joins are not getting hot enough or if it Au, then the increase in the Au content of the joint is increasing the melting point of the final solder joint. To some extent, this will also hap

Mark, This is a big topic. Where are you located, it would probably be best to hook you up with someone in your area. Anyhow, lead or lead free should be based on whether the circuits are lead or lead free. I would guess that cell phones would all

I would be glad to help you eliminate the solder balling and beading that you are seeing. As this is a fairly common defect, I would like to forward you an Application Note that we have developed that explains the cause and possible solutions. Most

This is what�s going on over the pond. The request to exempt the lead in electronics on environmental grounds, filed by the courageous fellow lead-free rebel John Burke (RoHSUSA) has been accepted for review by the EU TAC. http://ec.europa.eu/enviro
