WebDon’t use a PCB that has been in storage for more than 1 year without any protective cover sheet. Don’t use expired solder paste. Select a reasonable reflow setup profile for a particular PCB. Solder wetting behavior can be significantly improved by using nitrogen in the reflow oven environment. Reflow soldering with long industrial convection ovens is the preferred method of soldering surface mount technology components or SMT to a printed circuit board or PCB. Each segment of the oven has a regulated temperature, according to the specific thermal requirements of each assembly. See more Reflow soldering is a process in which a solder paste (a sticky mixture of powdered solder and flux) is used to temporarily attach one or thousands of tiny electrical components to their contact pads, after which the entire … See more The second section, thermal soak, is typically a 60 to 120 second exposure for removal of solder paste volatiles and activation of the fluxes, where the flux components begin See more The last zone is a cooling zone to gradually cool the processed board and solidify the solder joints. Proper cooling inhibits excess … See more Thermal profiling is the act of measuring several points on a circuit board to determine the thermal excursion it takes through the soldering process.
