Basic Information |
Uptime | ≥95% | (1 - unscheduled downtime/24H), unscheduled downtime refers to the time when the equipment malfunctions or is shut down unexpectedly. | |
| Speed | 18Xmm cells: Half-cut>6600-6800 strips/hour 220mm cells: Half-cut>6600-6800 strips/hour 1/3-cut>6600-6800 strips/hour 1/4-cut>6600-6800 strips/hour |
The capacity depends on the solder process. If the required solder time is too long, it may affect the production capacity. |
