Lead Free Wave Soldering

Lead Free Wave Soldering | 5 January, 2005

Hi,

Now in my wave the PCB TOP Side temperature before WAVE is 110 - 115 DegC and the Peak temp in the wave is 240 - 245. These informations are for an 63/37 Alloy.

What is the PCB TOP Side temperature and the peak temperature for Lead Free Wave Sn/Ag/Cu 217DegC ?

Thanks Frank

From what I have read so far the temps are, if not close to being the same for both alloy formulas. Preheat is a function of flux activation and thermal shock. Solder temp varies from place to place.
