AI Customer ServiceExample of reflow soldering thermal profile. Reflow soldering is a process in which a solder paste (a sticky mixture of powdered solder and flux) is used to temporarily attach anywhere from one to thousands of tiny electrical components to their contact pads, after which the entire assembly is subjected to controlled heat.
In the reflow stage, the solder paste melts and the flux helps with the process by removing oxidation from the pads and component leads. It gives the solder the necessary time to wet the molten solder without bridging between adjacent pads.
In the reflow area, the temperature of the board reaches the highest point. The reflow process melts the solder and fuses the solder joints. The high temperature causes the flux to reduce the surface tension at the joints of the metals causing metallurgical bonding. This causes the solder powder to combine and melt.
Solder reflow ovens are the equipment used to heat the solder paste and create a solid connection between soldered surface-mount components and the PCB. They use controlled temperature profiles to achieve optimal solder joint quality and reliability. The reflow process consists of four main phases: preheating, soaking, reflow, and cooling.
During the solder reflow process, various factors influence the quality of the solder joint, including the solder paste's composition, the type of reflow oven, and the temperature profile. Understanding these factors and how they interact is essential for achieving optimal soldering results.
The reflow phase is when the oven reaches its maximum temperature, causing the solder paste to melt and form a strong metallurgical bond between the component leads and the PCB pads. The range for reflow temperature is between 240 and 250 degrees Celsius for a Pb-free (Sn/Ag) solder.
