Main Points for Quality Control of Thin Film Resistors
Subject Content and Applicable Scope
SJ/T 10219-91
This standard specifies the main control methods and basic control methods of the manufacturing process of thin film resistors. This standard specifies the manufacturing process of three types of thin film resistors: carbon type, metal type, chemically resistive thin film type, and oxide film type. The quality control of the manufacturing process of other thin film resistors can also refer to this standard. When applying this standard, the content of the standard should be appropriately tailored according to the characteristics of the product manufacturing process. Reference standards

3.1 Raw materials and parts
3.1.1 Grading and monitoring requirements for suppliers of purchased and outsourced raw materials and parts According to the quality assurance and quality history of raw materials and parts suppliers, the suppliers are divided into excellent, good, acceptable and poor types and included in the grading table.
Advantages and Disadvantages: "Priority is given to the purchase of raw and auxiliary materials and spare parts from high-quality factories in large quantities, and the purchase of auxiliary materials and spare parts from high-quality factories is appropriate. The purchase of raw and auxiliary materials and spare parts from low-quality factories is prohibited; the purchase of raw and auxiliary materials and spare parts from low-quality factories is prohibited. Approved by the Ministry of Machinery and Electronics Industry of the People's Republic of China on May 28, 1991, and implemented on December 1, 1991
SJ/ 10219--97
Regularly audit the quality assurance capabilities of the factory for key raw and auxiliary materials and parts in the relevant supply chain: Combined with the acceptance of raw and auxiliary materials and parts, timely adjust the supply efficiency to a certain level, and put on the supply quality list of outsourced raw and auxiliary materials and parts. 3.12 Raw materials and parts are classified into key categories according to the requirements of the quality assurance requirements, which will not affect the final quality of the components. The raw and auxiliary materials and parts of the relevant supply chain can be effectively controlled. For general auxiliary materials and parts, the quality assurance requirements are shown in Tables 2 and 3.
For the safety classification and control requirements of key raw and auxiliary materials and parts in the relevant supply chain, see Tables 2 and 3.? 32.1 Importance classification of manufacturing management process
Based on the impact of process quality on product sustainability, process complexity and quality history, the whole process should be divided into three categories: critical, important and general: For key processes, quality control points must be set for key control: For important processes, effective control should be exercised, and quality control points can be set up when necessary; For short processes, appropriate control should be given. 3.2-2 Final manufacturing process
Take the key points of production equipment according to the quality level and the quality training plan related to the product: determine the sequence of control and measurement objectives, requirements, development methods, etc., and draw a "process diagram" with management, register table 3, 3.3 Production equipment
3-3.1 Equipment point control
According to the production equipment, the degree of "product quality sustainability" shall be more important, and the production stage shall be divided into four key, primary and secondary, key and important production equipment shall be maintained and expanded regularly, and production shall be certified according to the specifications, without the need for high qualification and seal. The inspection requirements for relevant links and production equipment in the manufacturing process of standard resistors are shown in Table 4. 3.3.2 Equipment operating hours record
The operator should write down the equipment operating hours record (operating time, downtime) during daily use of the equipment; 3.4 Post-epidemic requirements for full test
According to the requirements of product quality maintenance, the stability of test instruments and equipment should be improved. The fault test equipment should be divided into relevant, important and staged categories, and preventive maintenance plans should be formulated for each situation. The interval between each type of test equipment should be based on the standard. For the requirements of key links, evaluation and calibration of each section of the test equipment, please refer to Table 5.35 The working area is not in the environment of the tobacco T zone. The environment of the product is manufactured in a controlled manner. It is divided into three levels: key, medium and general. The minimum environmental quality requirements of each level are specified. For the requirements of the process hygiene level of the important and slow zones, please refer to Table 3.6 Failure analysis When the product takes effect, the failure relaxation is carried out under the process specified in the effective analysis diagram of Figure 1. Table 7.3. Product inspection or quality inspection includes batch inspection and periodic inspection. The inspection group or, the inspection period, the test method, the test item, the test wear, the installation requirements and the test method shall be in accordance with (5729.CB5730, C5721 and GB851GB5834.GR8552, 5, SX and other relevant production standards. The quality records of each inspection shall be regularly counted to reflect the quality of the manufacturing process under control. -3
3. Quality Management
3.9.1 Product Audit
$/T1021991
Product quality management records shall be reviewed once every October. 6.3.8.2 The process quality management system should conduct a process quality audit every three months. The quality audit record card is shown in Table 3.3.9 Personnel training Regular training should be conducted for all types of personnel. Those who do not meet the requirements shall not be allowed to work. The training requirements for all types of personnel are shown in Table 10. Table 1 List of suppliers of outsourced auxiliary shaft materials and parts Outsourced and outsourced auxiliary materials 254 Outsourced and outsourced parts (without brackets) Outsourced speed iron (oil) The same price should be used. The total position monitoring and control measures shall be determined for 1 year and the auxiliary materials and parts shall be supplied to the factory for batch supply at least once. 2 Each user factory shall estimate the quality of all auxiliary materials and parts used in the factory once for non-factory original materials and parts supply factories. The period of contract estimation is three years, and the technical requirements for batch production and special control measures shall be implemented. t||Connect and think
