Manufacturer	SD
Model	600S

Using liquid crystal computer + Intelligent Control System, high temperature control accuracy ± 1 °C (if the computer accidentally died, can realize off-line work, does not affect production) , to ensure stable and reliable control system;

Windows XP and Windows 7 operating interface, powerful, easy to operate, and with a key restore system;

The upper furnace body is opened with a cylinder jacking machine to ensure safety and reliability

Equipped with net belt tension device, smooth transportation, no jitter, no distortion, to ensure smooth PCB transportation;

Transmission Mechanism of synchronous Guide Rail (can connect with automatic mounter on-line) to ensure accurate width adjustment of guide rail, Long Service Life and anti-button curve

Manual Control Lubrication System, through manual to set the amount of lubrication transmission chain;

All heating areas are PID controlled by computer (can be divided into separate temperature areas opened separately. Can Be divided to reduce the starting power, heating time 10-15 minutes) ;

The network/chain transmission is controlled by computer in full closed loop, which can meet the needs of different kinds of PCB production

Has the breakdown sound and light alarm function (uses the LED lamp) ;

Reflow welding technology has many advantages over the traditional manual welding method. First, reflow technology enables efficient production lines. Through the use of automated equipment, reflow technology can greatly improve production efficiency, shorten production cycles, and reduce the occurrence of human factors and failures caused by human operations.

Second, reflow technology is very suitable for surface mount electronic components. Compared with traditional manual welding methods, reflow welding technology can more accurately weld electronic components, improve welding quality and product reliability. In addition, reflow technology can also enable the production of smaller and lighter electronic components, which is very important for the manufacture of micro electronic components.
