Features introduce independent control heaters top and bottom heaters are hot-air heating, the third IR heater is infrared heating, the top and bottom heaters can heat PCB from upper and bottom at the same time. temperature accuracy within there are multi segments can be set at the same time; IR preheating area is adjustable according to desire requests, to make PCB heating evenly. it can heat PCB board and bga chips at the same time. And the third IR heater can preheat the PCB board from bottom, to avoid PCB from deformation during repair process. The top and bottom heaters heat independently choose high accurate K type close-loop thermocouple, and PID parameters automatic adjustment system it can show seven temperature curves and the millions of groups data can be saved through U storage device with instant curves analysis function and analyzing BGA temperature at any time; the sensor is for precise temperature testing. Precise optical alignment system Adopt adjustable CCD color optical system, with a beam split, zoom in, zoom out and micro-adjust functions, has automatic chromatism resolution and brightness adjustment system, amplify to 230 X, mounting accuracy within 0.01mm. InMulti-function operation system Ù Adopt high definition human-machine interface, available for setting ¡°set up¡± and ¡°operate¡± to avoid error settings, The top heater device and mounting head 2 in 1 design, with automatic identify BGA chips and mounting height, it is of automatic soldering and desoldering function.it can set 6 segments rising temperature and 6 segments activity temperature, and can save N groups temperature profiles. Adopted all kinds of BGA nozzles, with 360 rotation, easy for installation and replacement, customized is available; ÚV-groove PCB support, with rapid, convenient and accurate positioning, can fit for all kinds of PCB board; Flexible and removable universal fixture has protective effects and no damage to the PCB board, suitable for all kinds of sizes of BGA repair. Superior safety functions With CE certification; after desoldering and soldering, there is alarming. when temperature goes out of control the circuit will automatically power off, it is of double over-temperature protection function. Temperature parameter has a password to avoid from arbitrary changes, with superior safety protection functions, can protect PCB board components and the machine from damage at any abnormal situation Specifications and technical parameters Total power 5300W Max Top heater power 1200W (1st heater) Bottom heater power 1200W (2nd heater) 3rd IR heater 2700W independent controlling left and right IR heaters) power AC 220VA10 50/60Hz Electrical materials temperature control system Adopted Dalian University of Technology Dimensions L640*W630*H900mm Temperature control K-type thermocouple (Closed Loop), intelligent temperature compensation system Positioning V type groove, with universal fixture P C B size Max 410A370mm, Min65A65mm Wooden box
