We do not have experience soldering to the PVD surface you plan to use. We use Titanium [Ti] stiffeners in wave soldering and our wave equipment manufacturer uses Ti fingers, nozzles, pump blades, and other parts, because solder doesn�t stick to Ti.

| Does anyone have angles on how to reduce N2 consumption at reflow process (i.e. process control equipment, etc.)? | | Any help would be appreciated | N2 consumption is very "machine" and process dependent. Some machine designs are better equipped

We use dry boxes manufactured by DMS Clean Room Products in Lawrence, MA. The phone number on the tag is (508)683-2325, but I think their area code changed to either 978 or 781 recently. We flow dry nitrogen through the box in order to ensure that

| | | All y'll: I could use your input on determining when to skim dross from a wave solder pot. | | | | | | On one hand, dross protects the surface of the solder from oxidation. On the other hand too much dross may affect solder joint quality. O

Based on what you�ve said, comments are: * There is no reason not to expect a trace of Zn in your 85/15 Sn/Pb solderability protection, but Sn/Cu IMC are more prevalent than Zn. * Intermetallic growth and oxidation are very different materials proper

1. What is your minimum dross generated that triggers you to procure an SRS? Your finance department probably has guidelines for the pay back of capital investments. Some companies use period of time to break-even. Others use a net present value
