It is a "touch-free" safer method for soldering thermally-sensitive IC's, QFP's, PLCC's, SOIC's and delicate ceramic capacitors, glass diodes and tiny SMD resistors. Precision Temperature Control. With closed loop feedback and a variable temp dial and a variable air flow dial, technicians control with even ultra-light settings ... 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, … Zobraziť viac 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 … Zobraziť viac 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 process where the maximum temperature is reached. An important consideration is peak temperature, … Zobraziť viac 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 cooled below this temperature, the … Zobraziť viac • Wave soldering • Reflow oven • Restriction of Hazardous Substances Directive (RoHS) • Thermal profiling Zobraziť viac 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 … Zobraziť viac The last zone is a cooling zone to gradually cool the processed board and solidify the solder joints. Proper cooling inhibits excess intermetallic formation or thermal shock to … Zobraziť viac Thermal profiling is the act of measuring several points on a circuit board to determine the thermal excursion it takes through the soldering process. In the electronics manufacturing industry, SPC (Statistical Process Control) helps determine if the … Zobraziť viac
