THIS! THIS is the size and shape of a tip that needs to be micro-soldered daily! Arrived quickly and well packaged. I LOVE this tip! It has a sharp tiny point for those very small joints. It has surface area and mass to transfer heat to the heat absorbing sandwich panel. He can pull the solder over the submerged pins so elegantly. But small! if you need a little advice - you need to preheat the board, preheat the work area to max 230°c with hot air or infrared - otherwise it won't do you much good.
