On 15th Nov, 2012, it was our first cooperation with overseas client. We promised to do the R&D of a new series in 30 days. We know deep down inside how important to keep our word especially doing business with foreign clients. During the process of material supply, debugging of components and sample, the whole team was doing our best. We strictly followed the ISO 9001 Quality Control and the standard of checking the finished products. At last we used 15 days in advanced to produce the approving sample for our overseas client. They spoke highly of our action and quality and decided to have a further cooperation with us.
