1. Compatible with MES, UPS and RFID functions.
Suitable with MES, UPS and RFID function.
2. The distribution of the manipulator is reasonable, which can effectively avoid the cross-contamination of the liquid and the reaction time of the tank.
Reasonable distribution of the lifts which can avoid cross-contamination of chemical liquid and reaction overtime of process bath effectively.
3. The structure layout is compact and reasonable. The acid area, the alkaline area and the high clean area are separated by partitions, and the equipment occupies a small space.
With compact and reasonable structural layout, acid area, alkaline area and high cleanness area separated by partition, with small footprint.
4. The advanced 400-piece double-layer slot structure can effectively improve the production capacity of the equipment.
Advanced double-layer bath structure improves the throughput effectively with 400pcs/batch.
5. The process tank adopts the combination of “scheduled and scheduled replenishment” mode and “time replenishment” mode, which effectively prolongs the service life of the liquid medicine and reduces the liquid exchange cycle.
Process baths combines the “feed & bleed” Mode with “Time Dosing” Mode, will extend the bath lift time and reduce the bath change period effectively.
6. The refilling solution adopts the linear detection of dual magnetostrictive flowmeters in the tank and the refilling tank, as well as the adjustable gas valve flow control structure, which effectively guarantees the initial distribution time and the precision of the micro-replenishing solution.
Dosing and Make-up adopt linear detection of the double magnetostrictive flowmeter inside the bath and the dosing barrel, as well as adjustable valve flow control structure to ensure the time of initial make-up and accuracy of accurate dosing effectively.
7. All materials in contact with liquid are optimized and upgraded to avoid the precipitation of impurities in materials.
Optimize and upgrade all materials in contact with process liquid to avoid precipitation of impurities.
8. The latest all-plastic low-temperature drying technology is adopted to ensure the cleanliness of the tank and the precision of temperature control, and to improve the life of the minority after texturing.
With the latest low-temperature drying technology to ensure the cleanliness and temperature control accuracy inside the bath, increase the minority carrier lifetime of solar cells.
