Recommend you consult device mfg.'s data sheet or their customer support line to confirm from engineering. I think you mean't 30 C, not 300 C, because the device will likely be toast at 300 C.

Thank you Russ for your comment. This failure cause should have been confirmed as contaminated plating surface causing poor solderability and conductivity, according to all the testing and observations. The only question remaining to me is that why

The manufacturer confirmed that it is humidity - the solder paste is too sensible to humidity. Now I tried Koki solder paste with good result. But, it does leave flux residue in good quantity. Does anyone have experience with Koki solder paste?

Hi laxman, Only to answer one of your question, actually almost 50% of component we use switch to lead free alloys. We receive confirmation for transition to lead free of at least 10 components per day. So, Yes I think all component will be ready

We're aware of no such standard. Check with ink suppliers [eg, Conductive Compounds, Coats Circuit Products, Creative Materials, etc] to confirm.

Hi, We used to clean 20 pieces SMT inductors before but no problem with this process. Please confirm what type of inductors is it SMT or hole type. What type of chemical and machine you are currently using? Maybe I can help you out.

Just to be careful, confirm this with your equipment supplier. We'd expect you could use argon in place of nitrogen in your selective soldering machine. We figure argon costs about 6X nitrogen. We've seen argon generators on ebay for ~$1000.
