Solder reflowing cpu

WebTomix89 - valid questions. First let me start by saying that many printed circuit board manufacturers utilize a soldering method called reflow soldering. In this method of manufacturing, the surface mount components are placed on the board with a solder paste that keeps them in place prior to the entire board being subjected to a reflow oven. Web9.4 Reflow Soldering In reflow soldering, the solder paste must be heated sufficiently above its melting point and become completely molten, in order to melt the balls of BGA components, causing them to collapse and form reliable joints. In the case of components with leads, the solder paste must wet the plating on
