Features:
6 spindles linkage, all the movements driven by 7 motors. Air head/PCB movements and optical locating system X/Y movements are all controlled by rockers. Easy operation. It is equipped with memory function suitable for mass reparation and will improve the efficiency.
Hot air head and mounting head are desingnde 2 in 1 with soldreing and desoldering automatically.
Upper and lower heaters are taking IR + hot air mix heating. Upper is with 2channels. IR heater works toward thd heating area in the meanwhile the hot air works. Thus the two heating methods can make up each other to speedy heat the PCB(The temp. goes up at rate 10C/S),and the temp. remains even.
Separate 3 heating zones. Upper and lower heaters to be one move together and can move in X,Y directions within bottom preheating area. Lower air head can move up/down and support PCB controlled by motor automatically, Upper and lower heater as one can move to the BGA when the PCB is fixed on the jig
Original bottom preheating board is made of bood quality heating heating material(IR plated heater)imported from Germany + constant temp .Glass(temp. Resistance up to 1800C),preheating area is up to 500*420mm.
Preheating board, jigs and cooling system can move as one unit in X direction that make locating PCB and desoldering more security and convenient.
The unique design of X,Y direction movement takes good use of the equipment space. It can rework super big PCB in the small size machine .The max. PCB size is up to 630*610mm
The jig device is with locating scale .The system can memorize historical locating scales that makes repeat locating very quickly and convenient.
Automatically take and place components on the jigs with locating scales.
Embedded vacuum pump. angle rotates in 360.contrlled by stepping motor, with memorizing function, precisely fine-adjusting and mounting nozzle.
Nozzle detects the height of placing and mounting automatically, the pressure can be limited in 10 grams. It can take and mount small BGA under 0 pressure.
Color optical vision system, with prismatic, double colors, zoom in and fine-adjusting functions ,equipped with aberration distinguish device, auto-zoom, software operation, wireless remote control 27X optical zoom, k can rework BGA in max. size 7070mm.
8 segments up/down temp.+8 segments constant temp.
Equipped with 5 thermocouple ports, can monitor and analyze the real-time temp. for multiple points.
