In reworking 0201, we: * Cut the 0201 in half with a side cutter * Heat the solder on each pad separately and flick the half 0201 off the board * Preheat a new component to +150°C with a hot plate * Solder a new 0201 on the undressed pads with a hot

Hello! I have a strage problem, we made some production with uBGA, BGA, 0201, 0805, and other type of component. We didn't put the uBGA and 0201 and BGA on the board at the end of the line we look a our solder joint and surprise the solder made a

On an assembly reflowed in air saw the same thing: 0201's with a grainular solder joint, but 0402's and above with perfectly formed joints. Reflow profile all within acceptable tolerances. Reflowing in nitrogen solves this problem, but increases t
