Speaking of regularity, and in keeping with the sustainability feature, it is possible for used or rejected wafers to be reclaimed several times over. Speaking of numbers in relation to wafer reclaiming services, no less than nine steps are being followed during the wafer reclaiming process.
The business has the capacity to produce several thousand new or reclaimed wafers in a single working day. This capacity extends across the globe whereby all finished products can be shipped accordingly.
