Use BTU reflow soldering, equipped with independent temperature control system and over temperature protection system; Standard lead-free soldering configuration, maximum heating temperature 350°C; The temperature control accuracy reaches ±0.5 °C, the PID control response speed is fast, and the transverse temperature uniformity of the mesh belt is ±2 °C; Forced cooling zone length 1219mm, air cooled; PCB product board effective working width of 2 inches to 18 inches (50-457.2mm); rail electric adjustment width; track long-term parallel precision, equipped with chain stop alarm and speed deviation alarm; Chain program-controlled automatic refueling lubrication, refueling amount adjustable; Electric upper cover lifting and lowering, and equipped with safety protection switch; Static pressure control, heating zone and cooling zone motor infinite frequency conversion speed regulation, can control the hot air pressure of the air outlet, according to different process conditions to set different pressures can improve temperature uniformity and peak value temperature range time, strengthen the flexibility of the adjustment curve, to avoid the offset of small components; Powerful moment overload protection between the conveyor chain and the drive motor; BTU special control software WINCON, simple and convenient operation; It has the function of automatic switching on and off. For the problem products that occur during the testing process, the OK rework station is used for manual maintenance, and the OK rework station is economical and easy to use, providing the rework function during the top BGA, CSP and QFN with professional performance; It can easily adjust the time of the reflux zone or adjust the heating rate, and make the PCB surface evenly preheat; Can be quickly raised to the required reflux temperature, for sensitive parts that cannot be heated more than 250 ° C, will not cause thermal damage; Dual convection preheaters can be switched or preheated at any time and at different temperatures or at different temperatures, optimizing process time to meet higher requirements of lead-free rework; Higher thermal performance can be achieved by connecting the reflux nozzle to the top reflux heater above the rework part and the center heater below it. Bottom nozzles add an advantage in preventing thermal damage to adjacent parts under the PCB.
