I'm re-spinning a board with two switching regulators on it: one using Line ar's LTC3810, the other using Micrel's MIC28304. The manufacturers' demo b oards and recommended layouts for these devices do not have thermals on cer amic caps which handle high rms currents. The pads for these caps are open ings in the solder mask over large, continuous copper planes. The caps are 1210 size. My assembly house said they had no problem hand soldering them , and the joints looked nice and shiny. I would always put thermals on sma ller parts; but is there any reason to have them on these larger parts whic h have to handle large rms currents?
TIA
