Control the quality of SMT patch processing from production management
It is undeniable that quality has always been the fundamental development of an enterprise. Whether it is the entity Wanda or Alibaba’s e-commerce empire, quality has always been the focus of the public. As a leading company in the field of SMT patch processing, Yitai Electronics has always been I am very concerned about the quality control of SMT production, and then introduced how to control the quality of SMT patch processing from the production link last time. Next, Dongguan SMT patch processing plant Yitai Electronics will introduce to you another important link of smt production quality control: Management measures.
Implementation of Management Measures In order to carry out effective quality management, in addition to strictly controlling the production quality process, we also adopt the following management measures:
1. After the components or parts processed by outsourcing are purchased into the factory, they need to undergo random inspection (or full inspection) by the inspector before entering the warehouse. If the pass rate is found to be less than the national standard, the product should be returned, and the inspection result should be recorded in writing.
2. The Quality Department shall formulate the necessary quality-related rules and regulations and the department’s work responsibility system. Regulations are used to restrict man-made quality accidents that can be avoided, rewards and punishments are clearly defined, and economic means are used to participate in quality assessment. The company has a monthly quality award.
3. Establish a total quality (TQC) organization network within the enterprise to provide timely and accurate quality feedback. The best quality of personnel is selected as the quality inspector of the production line, and the administration is still under the management of the quality department, so as to avoid the interference of other factors on the quality judgment work.
4. Ensure the accuracy of inspection and maintenance equipment. Product inspection and maintenance are carried out through necessary equipment and instruments, such as multimeters, anti-static wrists, soldering irons, ICT, and so on. Therefore, the quality of the instrument itself will directly affect the quality of production. It is necessary to send inspection and measurement in time according to regulations to ensure the reliability of the instrument.
5. In order to enhance the quality awareness of each employee, we have set up quality publicity boards around the production site to regularly announce the causes and treatment methods of some quality accidents to prevent the recurrence of such problems. At the same time, the quality department draws the daily production quality defect statistics (reflow PPM number, wave solder PPM number) on the quality coordinate chart, so that everyone can know the production quality of the day in time, so as to take corresponding improvement measures.
6. A quality analysis meeting is held every week. The meeting was prepared by the supervisor of the quality department and presided over by the supervisor of the production department. The meeting time starts from the morning of work, and the time is about 10 minutes to 30 minutes. Participants are representatives of the production line quality management team, production process supervisors, quality department supervisors, production department supervisors, line leaders, etc. The content of the meeting: put forward the quality problems that occurred in the last week, discuss and determine the countermeasures to solve the problems, and propose the person or department responsible for solving the problems. The meeting is required to be short and well prepared in advance to avoid excessively long meetings.
7. To improve the quality of products, we should rely on all employees. It is not enough to simply make the best efforts of the quality department. Because product quality is produced by optimized design, advanced technology, and high-quality workers, rather than by quality inspections, all employees of the company have strengthened their quality awareness. During the production process, we have proposed the “struggle for zero defects”. The slogan, in fact, this goal is difficult to achieve, because there are so many links in the SMT production process, it is impossible to ensure that every step does not occur a little bit of error, so “zero defect” is just an ideal culmination. But the effect of proposing a slogan is quite different from not proposing it. Because we have put forward the goal of “zero defect”, we will try to get close to it in the production process. The closer it is, the better the product quality. At present, the defect rate of our reflow soldering can be controlled below 50PPM, and the defect rate of wave soldering is below 30PPM, and the product quality has been greatly improved.
Chip processing equipment
There are many factors that affect the quality of SMT production, but as long as we formulate a complete production quality control process and strict management measures, and use and implement them in actual work, we will definitely produce high-quality products. ~SMT production quality control methods and measures In today’s increasingly fierce competition for electronic products, improving product quality has become one of the most critical factors in SMT production. The level of product quality is not only a sign of the level of enterprise technology and management, but also closely related to the survival and development of the enterprise.
