FS Technology's Quality Assurance for high volume PCB Assembly

The biggest drawback of mass production is the need to solve product quality problems, but FS Technology has more than ten years of rich experience in this field. In our production and assembly workshop, we can mass-produce more than 10,000 finished PCBA boards for you at the fastest speed.

Precision Design : First-class engineers and designers make detailed and accurate PCB designs and prototypes, because if a minor error comes can disturb bulk PCBA fabrication process. So our trained engineer look after each step carefully to perform the designing and prototyping accurately.

Low Rework Rate : To make sure less component failure and high-quality product creation we get the component from certified and authorized vendors. A variety of different testing methods and positions are inserted throughout the wholesale project process.

Experts EngineersWe are equipped with expert engineers and machines to make the complete assembly accurately. They take care of the complete processes like manufacturing, procurement, supply chain, board testing, quality, assurance, etc.

High-Quality ProductsWe provide different services for the creation of high-volume PCBs. These boards have similar quality standards, since we perform different tests and inspection measures. Objectively, the time spent in mass production will inevitably conflict with the time required by customers, and in any case, we will meet all the needs of customers with unparalleled cooperation on the basis of high-quality production. The quality of products is more important and never compromised on it.
