Feature:
1.Embedded Industrial PC, high definition touch screen interface, PLC control, and instant profile analysis function. Real-time settings and actual temperature profile display can be used to analyzed and correct parameters if necessary.
2. Three temperature areas can independently heat and are multiple controllable and adjustable to ensure best integration of different temperature areas. Heating temperature, time, angle, cooling and vacuuming can all be set on the interface.
3.It uses precise K-type close circuit control and automatic temperature adjustment system, with PLC and temperature module to enable precision temperature control of ±2 degC. External temperature sensor enables temperature monitoring and accurate analysis of real time temperature profile.
4.V-groove PCB support for rapid, convenience and accurate positioning that fits for all kinds of PCB board.
5.Flexible and convenient removable fixture on the PCB board which protectsand prevent damage to PCB. It can also adapt to rework various BGA packages.
6.Various sizes of BGA nozzles, which can be adjusted 360 degree for easy installation and replacement
7.High precision digital video registration system, rocker to make the optical lenses move in forword/back and right/left. Observe the counterpoint of four corners of BGA and central point
8.X,Y direction and R angle adopt micrometer fine-tuning. Registration accuracy can reach ±0.01MM. Equipped with high-definition liquid crystal display.
9.There are 6-8 levels of variable and constant temperature controls. Massive storage of temperature curves which are Instant accessible according to different BGA. Curve analysis, setting and adjustment are all accessible via touch screen.
10.Including Voice "early warning" function. 5-10 seconds before the completion of uninstalling or welding, voice reminder / warning to get the workers prepared. Cooling system will start after vertical wind stopped heating. When the temperature drops to room temperature, the cooling process will stop, so that the machine will not age after heated up.
11.Built-in vacuum pump
12.CE certification, with emergency switch and automatic power-off protection device when emergency happens
