Mandy, you chicken. You should throw that xray machine in the lake!!! Typical DOE Wave Process would include: Trial Number|| Conveyor Speed (m/min)|| Preheat Temp. (C)|| Soldering Temp. (C)

Wetting with lead free at wave is a bit different. You may need to increase your flux parameter to gain top side wetting. May get rid of the voids too.

Hi Ken What exactly the best reffered angle for Sn/Pb & Pb-free soldering? Is there a site where I can read the basic engineering concepts about this topic?

About the anlge typically is 5-7 depending on the machine. If solder smt components, the best is to use (swich on) double wave machine - (swich on both) chip and laminar wave. Regards.

Hi, I`m thinking what would be the best way to avoid icicles on lead free solder!

Good day, What type of solvent are you using for stencil cleaning during production? Does anybody use VIGON SC202 for stencil cleaning? What type of solvent can you recommend? Thank you. BR, Pavel

Vigon products are good. What does the supplier of the material [eg: paste, glue, whatever] that you're trying to clean from your stencil say that you should use?

Good day, So, only material supplier recommendation is the basis for solvent selection. Am I right? BR, Pavel

No. Aqueous Technologies, Kyzen, Petroferm, Zestron, Alpha Metals and many more companies have tested their chemical for use with many different production materials and should be able to discuss the effectiveness of their chemical. Beyond that, ma
