Quality Policy

Quality First" is the foundation of everything that LEISHEN practices. Quality is no longer limited to the performance of finished products, but includes cost, delivery, service and environment as well. LEISHEN believes that quality represents the customer’s level of satisfaction in all these areas.

Safety is also part of LEISHEN’s manufacturing philosophy. Safety is upheld by the LEISHEN Group as a corporate objective and is well supported by corporate management. Not only does our Corporate Quality Assurance Division adhere to the policy of placing quality first, it is also a company-wide practice. Significant attention is paid to every manufacturing process, from the development of new products and new manufacturing systems to the purchase of raw materials.

Quality & Reliability
LEISHEN has built comprehensive quality and reliability assurance and control systems into our processes and services from technology development to production. In addition, we have various labs and analytical tools to perform material analysis, product failure analysis and yield enhancement, reliability qualification and monitoring, as well as tool calibration.

To ensure a consistent level of quality and flexibility for our customers, LEISHEN uses a "PPM" concept whereby all equipment and process recipes are tuned to achieve the same test and yield results at any of our fabs.

Quality & Reliability System
To achieve high-quality delivery of our services, LEISHEN integrates quality standards and procedures through our entire operations chain. These include:

• Built-in APQP, FMEA, MSA reliability test in our technology development and
   production processes.
• Process reliability monitoring during manufacturing.
• Strict quality control of incoming raw materials and outgoing products.
• Stringent monitoring of in-line processes.
• A built-in reliability database that tracks, package and product  level  reliability
   through the development, qualification and production stages.
• Implementing statistical process control (SPC) and CP reliability control in
   mass production for fast feedback and continuous improvement.

• Product quality monitoring.
