IPQC details daquan

IPQC is the abbreviation of input process quality control, which means process control in Chinese. It refers to the product quality control from the production of materials to the final packaging of products.

Basic Introduction Chinese Name: Process Control mbth: Input Process Quality Control Abbreviation: IPQC Purpose: Ensure the input quality, also known as: Brief introduction of manufacturing process quality control terms, IPQC purpose, IPQC method, related introduction and job responsibilities overview. Brief introduction of terms IPQC is process control, which refers to product quality control from raw material input to final packaging of products. IPQC is also called process quality control, or production process quality control, and the English full name is input process quality control. Because the inspection method adopted by IPQC is patrol inspection between processes in the production process, it is also called patrol inspection. IPQC generally adopts sampling inspection, and the inspection contents are generally divided into sampling inspection of product quality in each process, inspection of operation methods and means of operators in each process, and random inspection of control plan content. The process of realizing IPQC target product is a complex human-computer interaction system, which consists of different processes. In this process, there is both logistics and information flow. In order to make the output meet the requirements of customers, the following aspects must be realized: 1. Ensure the input quality. 2. The machinery and equipment are stable and the production capacity is sufficient. Personnel operate in strict accordance with standards. 3. The key parameter (CTQ) closely related to product quality is in a stable and controllable state. 4. The information is accurate, complete and timely, which can play a guiding role. 5. An effective process monitoring mechanism can detect the anomalies in the process in time. 6. Feedforward mechanism enables the process to correct anomalies in time. 7. The reverse feedback mechanism can effectively prevent the loss of defective products. 8. Review the initial and final products, and provide team quality assurance 9. Smooth process interface to prevent waste of resources. The implementation of the above aspects depends on the continuous efforts of IPQC. It is with the above support that this process really becomes a process to ensure the quality of output. Therefore, the work of IPQC has realized the transition from process to process, so that the output is no longer a simple addition of inputs. However, it adds value in quantity and quality. IPQC methods mainly include the following methods:. Perform process audit according to the audit list-the basic state of the process will not change by product. 2. Check the working procedures-materials, tools, auxiliary materials, methods and personnel. 3. Confirm the first article-it varies according to the product, process, equipment, software and personnel. Just in time Feedback mechanism between processes-timely feedback of relevant information 6. The early warning mechanism plays a role. Control of nonconforming products-identification, isolation, differential placement and statistical analysis 8. Material input-put the right material into the right product at the right time, and record it accurately in time to facilitate traceability. Product standards-process standards and functional requirements: 10. Conduct sampling inspection on the output of each process-confirm that the process is stable and has sufficient capacity, and the products are qualified. This paper introduces the contents of IPQC process inspection and prenatal preparation. According to the production plan, determine whether the BOM, ECN and color scheme of the production model are consistent with the online materials, and determine the inspection specifications. If IQC has samples, provide them to IPQC and production inspectors to confirm whether the incoming inspection is selected online. In case of online selection, IQC shall instruct the online operator to select samples. 2. Whether the online materials meet the product BOM requirements, ranging from screws to cartons, whether each box (bag) of materials is confirmed in time, and whether the types, models and specifications of online materials are complete and correct according to the product BOM and ECN. 3. Whether to hang SOP/WI according to the process flow 1 and arrange the work content in process control. Fill in the inspection carefully and on time. Check the electric batch torque checklist to see whether the electric batch torque of the corresponding station meets the SOP requirements of the station and record the report. 2. Check whether the corresponding label of the soldering iron checklist and the temperature of the soldering iron in the station meet the SOP requirements and record the report, and whether the soldering iron has grounding and leakage prevention measures. 3. Make sure there are qualified first articles and templates. 4. Check whether the instruments and fixtures are normal with the first article and sample; Ensure that it is within the validity period of instrument calibration; Confirm that the set parameters are consistent with the product requirements. 5. Whether the employee's operation is consistent with the work instruction, drop down whether the first five products are followed from front to back, and then sample again for 5 /2H/ station for confirmation. 6. Whether new products and new employees focus on inspection, special inspection, substitution, trial production and franchise release must focus on auditing, recording the situation and feeding back the results. 7. The operation is fixed and there is no accumulation, so be careful. Whether the qualified products will be pulled down by employees' self-inspection and cross-inspection. 8. Whether the unqualified products are identified and recorded on time. 9. If the materials can't be used normally due to poor incoming materials and operation, which will affect the completion of the order, it should send & gt feedback 10 in time. The proportion of defective products in test stations (such as semi-finished products test, function test and appearance inspection station) exceeds the quality target. Please fill in> and track the processing result. A. The single defect rate in normal production (mass production) is 3%-5% per hour, so it is necessary to open the feedback sheet for quality exception handling-the total defect rate in engineering analysis is 5%- 10%- engineering analysis B. The total defect rate in trial production is 10%, so it is necessary to open the feedback sheet for quality exception handling-engineering analysis C. Stop the production line. % Requirements: engineering analysis 1 hour to provide solutions. If there is no reply, the line will be stopped 1 1. Whether the materials, semi-finished products and finished products are placed with implementation status identification and signature 12. Check whether the report records are complete, clear and clear at a glance, and whether the "total number" and "bad number" are recorded every hour. 13. Do you understand and follow up customer complaints and returns? The rework situation must be followed up, the statistics are not good, and the results are fed back. Keep "status quo", "existing things" and "site" 14. Sockets, batteries, contacts, etc. The wear test should be replaced and recorded in time (for example, the charging port of the charger is fragile and the interface of the mobile phone charger is damaged). 15。 Any operation, packaging and storage will not have a potential impact on the quality. 16. When the customer relaxes the product standard and fully accepts a certain function and appearance, the customer is required to sign the form to confirm or sign the sample. 17. Customers' requirements for product standard changes should be promptly fed back to online PQC and QA. So as to realize the unification of standards. 18. Evaluate and review online PQC work according to QA sampling results, and make Zhou Du summary. Summarize job responsibilities. According to daily production and in strict accordance with inspection standards, check the production of first articles and inspection products; The first product after inspection shall be stamped with the qualified seal and put in the corresponding position; If nonconforming products are found, relevant personnel shall be immediately notified to make improvements to avoid a large number of nonconforming products; Track products with unstable quality, report problems to superiors or related personnel in time, find out solutions and solve problems in time; Assist supervisor to deal with customer feedback and complaints, and ensure that defective products and good products in the warehouse are effectively handled; Responsible for signing and confirming the first piece, to ensure that no samples are produced and unqualified products are not delivered; Overall planning of workshop quality management.
