1.Control System: PC + Siemens PLC control system,accurate temperature control and more stable,ensures temperature stability rate to be

more than 99.99%.

2.Vacuum system:PCB directly enters the vacuum unit from soldering area. Start the vacuum process to reduce the vacuum pressure to

100mbar-5mbar. The internal gas such as pores and cavities overflows from the molten solder joint, which can reduce the void rate to less

than 2%.

3.Hot air system: first-class heating module, the best temperature zone interval design makes optimum temperature uniformity and repeat.The

effective utilization and thermal compensation efficiency,it needs less than 20 minutes from temperature control accuracy ± 1 ℃ ambient

temperature to a temperature stabilization .

4.Monitoring Software:Windows interface, traditional and simplified Chinese and English online free switch, and operator password

management, easy to operate.Operation records, temperature curve measurement and analysis functions, virtual simulation, fault

self-diagnosis, process monitoring, automatic generate and save process control documents, substrate transport dynamic display.

Product:

 

From zero to 240 °C due to optimized heat transfer

 

Each product has its own requirements in the manufacturing process. Optimized heat transfer over the entire soldering process is the basis for

best possible results.

The LV-Series offers flexibly controllable preheating zones within which your PCB is preheated and prepared for the actual soldering process.

The individual zones can be controlled independently of each other via fan frequency, and assure best possible processes.

The LV-Series is equipped with special nozzle sheets for optimized heat transfer by means of uniform air flow over the PCBs. Flow speeds in the

upper and lower heat zones can be separately controlled, assuring that your PCB is heated up.

Saddle profile

The component is brought to a temperature of at least 240 °C for

soldering. Using a saddle profile the board is gradually heated in line

with pre-defined, individual temperature ranges. Even components

with differing thermal masses are heated homogeneously and

temperature differences minimised.

Linear profile

With a linear profile, the component is not heated in a stepped

manner during soldering, in fact it is heated along an identical

linear temperature gradient. Linear profiles can reduce cycle times

and can help to reduce soldering errors such as tombstoning
