Visual inspection items and qualification criteria of welding effects for melf resistors side solder width
minimum side 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 high the tin filtration the better the solder strength will be.
the most important of the the requirement of getting wide solder width at the side of melf resistors is the sufficient amount of tin paste on the solder pads. there are information in our file provided the detailed date of the dimension of the pads and the thickness of the tin mesh for customers reference.
