Terms of product production

For example, if we want to produce commercial mobile phones, some terms will be involved. These names usually only appear in OEM and ODM. However, the current devices, especially the production of custom devices, we have the opportunity to join. The following are some related procedures. The collection here comes from the Internet, but the source is not recorded, and I am too lazy to find it again. In the chronological order of the process:

　　EVT (Engineering Verification Test)

: Engineering verification/engineering sample verification testing is a technical review required to switch from the engineering prototype stage to the development prototype stage. Design verification at the initial stage of product development. The designer performs initial test and verification when implementing the sample, including functional and safety tests. Generally, R & D fully verifies the sample. Because it is a sample, there may be many problems, the test may be performed multiple times.

　　Design Verification Test)

Design verification test. Solve the problem of the sample in the EVT phase. It is an indispensable part in hardware production, including mold testing, electronic performance, and appearance testing. It is a technical review necessary for the transformation from the Development prototype stage to the production prototype stage.

　　DMT (Design Maturity Test) Maturity verification, which is saved in many processes. MTBF (Mean Time Bet ween Failure), HALT & HASS, high speed life test, and high speed stress screening test can be performed at the same Time as dvs in high temperature environments, it is an effective method to test the defects of the product.

　　PVT (Process Verification Test)

Verification and testing in small batches. It mainly verifies the implementation of various functions of the new model and tests the stability and reliability. It is a technical review necessary to switch from the production prototype stage to the production stage.

　　MVT (Mass Verfication Test) Mass production verification, but this is not available in general information. Verify the consistency of products in large batches during mass production, which is verified by DQA.

　　MP (Mass Production)

Production stage.

In addition, we often hear that BOM is the Bill of Material (BOM ).
