1. Statistical process control

Statistical process control (SPC) is a manufacturing control method, which is based on the data collected by the control items in manufacturing, through analyzing the process capability and standardizing the process, finds the abnormality in the process, and immediately takes improvement measures to make the process return to normal.

2. Analysis of measurement system.

Measurement system analysis (MSA) is to analyze the measurement system that can repeatedly read all parts, evaluate the quality of the measurement system, and judge the acceptability of the data generated by the measurement system.

3. Failure Mode and Effect Analysis (FMEA, Failure Mode &; Effect analysis)

As a planning tool and a preventive measure, the potential failure mode and consequence analysis (FMEA) of product quality aims to find and evaluate the potential failure and its consequences in the product/process. Look for measures to avoid or reduce potential failures, and make continuous improvement.

4. Advanced product quality plan

In order to meet the requirements of products, projects or contracts, before new products are put into use, the method used to determine and formulate a structured process to ensure the production of a specific product or series of products that meet customer requirements. Provide guidelines for making product quality plans to support the development of products or services that customers are satisfied with.

5. Production parts approval process

The approval procedure of production parts is a practical technology, and its purpose is to verify that the products manufactured by production tools and processes meet the technical requirements through the product approval and recognition procedures before the first batch of products leave the factory.
