Flow soldering 与 reflow的区别
Did you know?
WebReflow solder profiles usually have four stages, preheat, thermal soak, reflow and cooling. The aim of the preheating stage is to accumulate heat smoothly in the board and the components. The Temperature gradient is important because too quick changes of temperature can cause damage to components. During the thermal soak the flux is … Websoldering process in that the reflow of solder is accomplished using a heating element called a thermode which is heated and cooled down for each connection. Pressure is applied during the entire cycle including heating, reflow, and cooling. A pulse-heated control delivers energy to the thermode, which is mounted on the reflow soldering head.
