Edwards GXS Series vacuum pumps improve module laminator throughput

•  
  The GXS 450 and 750 pumps provide faster chamber evacuation for enhanced laminator throughput and higher productivity.

Edwards, a global supplier of vacuum and abatement equipment and services, has introduced the GXS 450 and 750 series of dry-vacuum pumps optimized for solar laminator applications. The new GXS series is claimed to deliver higher throughput and productivity, while at the same time providing a lower cost of ownership.

Problem

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.
