PCB News - The role of the quality department in PCBA processing

In the PCB industry, it seems that the quality department is the least to be seen, not recognized, and the most difficult to do: 1. Require all departments to comply with regulations, and some people will find it cumbersome and cumbersome, which affects efficiency; 2. Detect defective products and require rework Or it is scrapped. Some people think that this is a waste of cost, and you have done everything. As long as it is not a functional problem, of course, you can pass it. Otherwise, why didn't you find it when you produced it, and you didn't stop it; 3., It is because the quality department requires too much, which hinders the production efficiency, and the output is up. That is the result of the hard work of the production department. What does it do with your quality department? The quality has improved, it means that the quality consciousness of the production department is strong, and the quality has decreased, it is the inaction of the quality department...

All the above seem to indicate that the quality department is really dispensable, and keeping it hinders efficiency and increases costs. So some factories really cancel the quality department, and the remaining part is not canceled. Maybe it is because the department is missing and incomplete. So I reluctantly kept it, but it was the most unstable of all departments. Don’t you see, there are often news about the factory recruiting quality managers and quality managers? So what role does the quality department play in PCBA processing manufacturers? Why is it so hard to do? First of all, let me know with you about the quality department in the PCBA factory

The quality department is divided into three major parts:

Quality management system

The popular interpretation of the quality management system is a set of management system built around the quality of the company’s products. The source of the entire company’s operations, the core of the company’s operations, the establishment of corporate organizational structure, the functions of each department, job responsibilities and requirements, etc. must be Developed in accordance with the requirements of the quality management system.

The steps to establish a quality management system are: select a certification company-write a manual-implement the system-pre-audit tasks-obtain certification. The writing of the manual is to combine the standards and elements of the quality management system with the specific conditions of the company into specific requirements that are easy to understand for the participants. The manual is the first-level document we often say; and then the operation process of each work is determined according to the content of the manual., That is, the program file we often say-the second-level file; and then write the specific operation method for each job according to the program file, that is, the operation guide-the third-level file; the data generated during the team operation is recorded, then It is a record file-a four-level file.

For example, the content of 6.0 in the Ts6949 quality management system standard is "resource management", and the subdivision of resource management is: 1. resource provision; 2. human resources; 3. infrastructure; 4. working environment. When writing a quality manual, you must add corresponding resource management requirements, and then continue to subdivide and write requirements for each point according to the characteristics of the enterprise. For example, human resources can be subdivided into: 1. personnel competence requirements; 2. personnel training; 3 incentives System and so on. Personnel training also includes ability training and meaning training. Then, according to the elements of human resources in the manual, compile the work process of human resources in the second-level procedure document: set up a human resources department, divide the human resources department into recruitment department, training department, etc. according to the work content of human resources, The work content continues to be subdivided into: first formulate job responsibilities and requirements, and then interview candidates who meet the requirements through various channels, establish files after passing the interview, and conduct pre-job training. With the process, it also needs operation methods (including operation requirements, time, location, etc.), which requires the preparation of three-level operation guide documents, such as training operation guidelines: training content determination, training frequency, training location, training object, and training Record, the purpose of the training.... The sign-in form of the trainees is one of the four-level record files.

With the above level one, two and three documents, all positions in the company must work in accordance with the requirements of the documents. The entire business operation is carried out according to the documents. Therefore, the quality management system is not only the management of the documents, it is the baton of all the actions of the enterprise. It almost contains the responsibilities and working methods of all positions in the company. The document only converts the requirements into written things for us to inquire.

Process control

Process control, as the name implies, is to control the production process. Generally, the process control of the PCBA enterprise quality department refers to PQC. Its main responsibility is to monitor the production process of the product, so that the producer can work in strict accordance with the requirements of the document to avoid random operations. Quality issues.

In order to help everyone understand the work functions of PQC, we might as well compare PQC to police, production personnel to ordinary people, and work norms are equivalent to legal provisions. First of all, in order to ensure the orderly life of ordinary people, the state has formulated various legal provisions to restrain ordinary people. To avoid the social chaos caused by the people's randomness, the same is true for enterprises: In order to avoid random operations by production personnel, work guidelines and operating specifications are formulated to unify everyone's behavior and avoid random actions that cause quality instability. But if there is no supervision, there will always be people who report that they are lucky enough to pass the ideals, so the country has produced the police, and the company has also produced quality control personnel. In many PCBA factories, there is always a hostile relationship between production personnel and quality personnel. It seems that the existence of the quality department was created to hinder production. Let us imagine how the lives of ordinary people would be like if there were no police in a country: thieves were rampant., Homicides, crimes, fights, and road robberies.....At this time, people may live in terror all the time, afraid of being stolen, afraid of being robbed, afraid of being retaliated...Of course this kind of life It’s not what you want, so the existence of the police is to create a good environment for the people to live and work, and to have a better life for the people. Similarly, the PQC of the PCB company exists to ensure the smooth progress of production. If there is no quality department, keep it. Lucky production staff always cut corners and do things casually. Do quality problems continue to occur and seriously hinder production efficiency?

Therefore, in a society that opposes the police, it is only the criminals who violate the law and the people who obey the rules and disciplines welcome the police. The PCBA manufacturers who oppose the PQC are only the employees who do not operate according to the norms, so if the factory opposes the quality department, Then he must be an unqualified employee who does not abide by the rules.

Quality check

Quality inspection is to inspect the produced products in accordance with quality standards. It includes semi-finished product inspection and finished product inspection. Generally, the quality inspection of PCB factories includes QC and FQC, that is, the semi-finished product inspection of each process and the finished product inspection before shipment. Quality inspection is much simpler and simpler than quality management system and process control. Inspectors only need to be familiar with the inspection standards and judge strictly according to the standards.

In short, the work purpose of the Quality Department is to standardize and standardize all behaviors, and to supervise and urge other departments to implement them. Many small and medium-sized PCB companies only have the quality inspection part of the quality department, so they feel that the function of the quality department is not great, so they directly cancel it. That is because they do not have a sound quality system at all, so they did not fully play the role of the quality department.
