Guiding ideology of 1 SKD test scheme
(1) conforms to relevant technical specifications and test standards.
Mobile phone test
(2) Have sufficient test speed and accuracy.
(3) Under the premise of meeting the production capacity requirements of the production line, the equipment investment should be economical, including the purchase of CDMA mobile phone comprehensive tester, transmission belt equipment, test fixture, other test equipment, production line statistical management equipment, etc.
(4) The technical indicators, models, specifications, data and other requirements of the test instruments to be purchased should not only meet the comprehensive requirements at the present stage, but also take into account the future scalability, upgradeability and maintainability.
(5) Take up all kinds of resources of the company as little as possible, including manpower, material resources, financial resources, production site, air conditioning, electricity, compressed air, etc.
(6) Make full use of the existing GSM mobile phone production line conditions (if any) to improve, adjust and optimize the production line, so as to further reduce the cost of producing mobile phones.
Classification, test scale and related standards of CDMA mobile phone function test items
(1) RF transceiver index test (test of transmitting power, transmitting spectrum, receiving sensitivity, etc. ): The test standard is the communication industry standard YD/T1050-2000 of the People's Republic of China; American TIAIS-98 minimum performance standard for dual-mode mobile stations; Technical requirements for air interface of 800MHzCDMA digital cellular mobile communication network.
(2) Audio index test: check or test the sensitivity, ringing loudness, earpiece loudness, distortion, sidetone and hands-free function of transmitted audio.
(3) Check 3)LCD and menu functions: see if they are consistent with the contents described in the manual.
(4) Check the touch and strength of each key.
(5) Inspection of battery quality: Check whether the electrical connection quality between the battery and the motherboard is reliable, and measure the battery capacity, output voltage, short circuit protection and other indicators.
(6) Quality inspection of the charger: check whether the quality of the electrical connection between the charger and the motherboard is reliable, and test the input characteristics, output characteristics, charging characteristics, incoming calls during charging, power failure during charging, floor drain current and other indicators.
(7) Reliability test: By applying certain external environmental stress (high temperature, low temperature and vibration) to the mobile phone, the reliability index of the product is checked. This is very important, it can find many product quality problems. The test standard is GB/T2423.8- 1995: Environmental test of electrical and electronic products.
(8) Field test in the actual CDMA communication network: This test needs to be tested and verified under different environmental conditions such as different time, different place/terrain and interconnection with different network users. The test standard is CDMA(IS-95A) digital mobile phone network access inspection detailed rules 200 1 May Ministry of Information Industry.
(9) Mobile phone shell quality inspection
(10) Check the reliability and stability of software and man-machine interface operation.
(1 1)DC power consumption indicators: shutdown current, standby current, call current and standby time test.
Most of the contents of the above-mentioned SKD production test scheme for CDMA mobile phones can also be used for SKD production of GSM mobile phones.
