Soldering Heat Gun Wattage

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 assembly is subjected to controlled heat. The solder paste reflows in a molten state, … See more Preheat is the first stage of the reflow process. During this reflow phase, the entire board assembly climbs towards a target soak or dwell temperature. The main goal of the preheat phase is to get the entire assembly … See more The third section, the reflow zone, is also referred to as the “time above reflow” or “temperature above liquidus” (TAL), and is the part of the … See more The term "reflow" is used to refer to the temperature above which a solid mass of solder alloy is certain to melt (as opposed to merely soften). If … See more Thermal profiling is the act of measuring several points on a circuit board to determine the thermal excursion it takes through the … 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 oxide reduction on component leads and pads. Too high a temperature can … See more The last zone is a cooling zone to gradually cool the processed board and solidify the solder joints.

WebAug 25, 2024 · IR and convection reflow use two different heating and cooling mechanisms. In IR reflow the heating and cooling mechanisms are radiative because the air is static, whereas in convection refow the heating and cooling mechanisms are convective and rely on the movement of a heat through a conducting fluid such as air. Webreflow, often a good solution is to reduce the oven heater setpoint temperatures and conveyor speed. This allows more time for the conductive flow to occur and the product …
