. As of today, double-sided boards are generally soldered to the top (component side) by reflow, and then soldered to the bottom (pin side) by wave soldering. A current trend is toward double-sided reflow soldering, but there are still some problems with this process

. These problems will affect the life of the reflow solder joints. 3. The proper size and shape of the solder joints. To have sufficient life of the reflow solder joints, it is necessary to ensure that the shape and size of the solder joints meet the requirements of the structure of the solder joints
