Despite the all the QA steps preceding the departure of the product are designed to assure the necessary quality, there’s a final one that adds surplus security for our customers. We carry out a selective outgoing QC via total inspection of certain number of parts from each batch. The batch leaves our warehouse only in case of zero defects. In case a faulty part is found an extended lot is selected for inspection and the same principle is applied. If there’s a faulty piece in the extended extracted lot a 100% of the batch is carried out. All our shipments are accompanied by 3.1 certificate upon customers’ request.
