S7 Rework Station Features：

The linear slide is adopted to enable fine adjustment or rapid positioning of the X, Y, and Z axes, featuring high positioning accuracy and fast operability.

This machine is equipped with a touch - screen human - machine interface and controlled by a single - chip microcomputer. It can store multiple sets of user temperature curve data. It has a power - on password protection and modification function. During operation, temperature data is presented as curves on the touch - screen display, and it has an instantaneous curve analysis function.

It uses independent heating in three temperature zones. The upper and lower temperature zones are heated by hot air, and the bottom temperature zone is heated by infrared. The temperature can be precisely controlled within ±3°C. The upper temperature zone can be freely moved as needed, and the second temperature zone can be adjusted up and down. The upper and lower heaters can be set with multi - stage temperature control simultaneously. The output power of the IR pre - heating zone can be adjusted according to actual requirements.

The hot - air nozzle can rotate 360°. The bottom infrared heater can ensure uniform heating of the PCB.

High - precision K - type thermocouples are used for closed - loop control, and an external temperature measurement interface is provided for precise temperature detection. The PCB is positioned with a V - shaped groove. A flexible and movable universal fixture is used to protect the PCB, preventing damage to the edge components of the PCB and PCB deformation, and it can adapt to the rework of various BGA package sizes.

A high - power cross - flow fan is used to rapidly cool the PCB, improving work efficiency. Meanwhile, a built - in vacuum pump and an external vacuum suction pen are provided for convenient and quick handling of BGA chips.

The machine has an alarm prompt function when the soldering work is completed. A "pre - alarm" function is specially added for user convenience.

This machine is CE - certified. It is equipped with an emergency stop switch and an automatic power - off protection device for abnormal accidents. In case of temperature runaway, the circuit can automatically cut off the power, and it has a double over - temperature protection function.
