Often viewed as a bottleneck within ‘back-end’ module processing steps, lamination of solar cells within the frame requires correct and consistent operation. Improving chamber evacuation times can improve throughput and productivity of a laminator, reducing manufacturing costs.

Solution

The GXS 450 and 750 pumps provide faster chamber evacuation for enhanced laminator throughput and higher productivity. The pumps incorporate Edwards's proprietary screw technology and high-energy drive. Chamber purge speeds of 450 m3/h and 750 m3/h have been optimized to deliver the rapid vacuum performance required for high-throughput solar lamination processes, while still offering robust performance, low maintenance requirements, long service intervals and advanced temperature control.
An optional booster package is also available to further enhance process chamber evacuation times and reduce the lamination cycle time. The closed-loop temperature control prevents pump fouling, and the pumps’ low running power reduces their overall cost of ownership. As with all Edwards’s dry pumps, the absence of oil eliminates the cost of the oil itself, as well as the downtime, labor and disposal costs associated with the neccessary oil changes.

Applications

Solar laminators.

Platform

The low running power of the GXS pumps helps reduce operating costs and the environmental footprint. At the same time, its compact size saves valuable fab floor space and allows the pump to be placed closer to the laminator for simpler installation and more efficient operation. The pumps’ low noise and low vibration also facilitate placement close to the tool to minimize impact on the fab working environment.

Availability

August 2011 onwards.
