Bill This drives solder suppliers nuts, because it's not analytic: Dross inclusion testing can be conducted on the base solder in the solder pot and the virgin solder. Conduct this test by heating a sample of solder, contained in a clear beaker,

We're changing solder bar and wire suppliers and are running impurity tests. Is there an IPC standard that lists acceptable limits for ultra pure, pure, solders for metallic and non-metallic impurities? What is the preferred method to test? We've

We would like to start testing our lead free wave solder machines in house. Mostly looking for lead and copper content. Malcom makes a relatively inexpensive machine that does this (STA-1 http://www.malcomtech.com/products_sta1.html). Does anyone

David, You just provided enough material to start an endless debate in an unexplored field (acceptable impurities, levels and effect on reliability in high tin content (lead free alloys). High tin content alloys have a high affinity to metals like C

I believe this is the only system on the market place and was developed by Panasonic in Japan with Malcolm. As stated it does check a limited number of elements but that was its intention when produced. I believe that only high volume shops would u

Has anyone in the US used this system? I am told that over 1000 systems are operating world wide...but find it hard to believe no one domestically is using this (if it in fact is worth its salt would more not use it?) Anyone? Anyone demo'd this? A

Solder bath eruptions

Have any of you ever experienced minor eruptions in your solder bath while it is heating up? Our solder bath splashes solder while it's heating. Once the bath is molten, it no longer does. Can anyone suggest a cause?

Rapid heating of solder caused solder underneath surface to expand and become pressurized. Check to see if power cycles on and off during warm up. A slower rate of of climb should help.
