4. Rework Station ZM R5850 Manual Preface Dear customer Thank you for using the BGA rework station ZM R6820G of Shenzhen Zhuo Mao Technology Co Ltd Features of 7M 5 850 1 Unique design of three heating areas operating independently to control temperature more accurately 2 First second temperature areas heat independently which can set up 8 rising temperature segments and 8 constant temperature segments to control It can save 10 groups of temperature curves at the same time 3 The third area uses far infrared heater to preheat and control the temperature independently so that the PCB can be fully preheated during the desoldering process and it can be free from deformation 4 Choose imported high precision K Sensor and closed loop to detect the up down temperature precisely 5 After finishing desoldering amp soldering there is an alarming When the temperature goes beyond control the electric circuit can cut off automatically with over heating protection 6 Use a powerful cross flow fan to cool the PCB rapidly to prevent it from deformation and ensure the welding effect 7 Use a V groove equipped with a flexible fixture for PCB positioning to protect the PCB from deformation when heated or cooled 8 This machine can be connected to a computer to be controlled more conveniently with a built in PC serial port and proprietary software attached to it 9 For large thermal capacity of PCB CSP QFP or other hig
