5.4 IR Soldering  
Rapid heating, partial heating or rapid cooling will easily cause defect of the component. So preheating and  
gradual cooling process is suggested. IR soldering has the highest yields due to controlled heating rates and  
solder liquids times. Make sure that the element is not 2.4 The IR reflow and temperature of Soldering for Pb  
Free subjected to a thermal gradient steeper than 4 degrees per second. 2 degrees per second is the ideal  
gradient. During the soldering process, pre- heating to within 100 degrees of the solders peak temperature is  
essential to minimize thermal shock.
