The world market leader in the field of solar wafer measurement increases its engagement for cell producers
Hennecke Systems, Member of the Meyer Burger Technology Group, delivers now specialized measuring tools for the cell line incoming wafer inspection. The leading manufacturer in the quality control of solar wafers has expanded its product portfolio accordingly.
The specialized system comes with a loading device, that unstacks wafers softly with a speed of one wafer per second and takes them in the measuring unit.
The measuring unit in its standard configuration inspects the wafers for their thickness, TTV, resistivity and lifetime as well as micro cracks. The accurate inspection of each wafer can help to save up to 400’000 USD/year especially because collateral damages caused by broken wafers are minimized. Optionally the new system can be extended with proven and tested measuring modules for saw marks, stain, edge defects, geometrical properties, sori (bending) and grain size. The system is capable to process slurry and diamond wire sliced wafers.
After the quality control the wafers will be sorted according to predefined criteria into carriers or polystyrene boxes.
This assures that a cell producer only processes A-quality wafers and yield and uptime of the production are optimized.
