8.3.3.3 Visual inspection 3:Minimum end solder width of MELF resistors after reflow soldering


minimum end solder width of melf resistors after reflow soldering in larger than 50% of the diameter of the resistors or larger than 50% of the width of the solder pad. the wider the solder width the better the solder strongth. 

the most important of the the requirement of getting wide solder width at the end of melf resistors is the sufficient amount of tin paste on the solder pads.
