All components on the PCB have the same temperature at the end of this zone should be, otherwise go to the reflux temperature zone because parts will produce a variety of uneven faulty welding. Usually the active temperature range is generally 120 ~ 150 ℃, if the temperature of the active region is set too high, the flexible circuit board technology, flux (cream) activation is not enough time, the slope of the temperature curve is incremented upward slope. Although some manufacturers allow the paste to increase the number during activation temperature, but the ideal temperature curve should be smooth temperature Shenzhen circuit board technology | PCB circuit board Process | Newell Chong (high merchant) by the Shenzhen-Inno Electronic Technology Limited.
