The quality of PCB products is produced, not inspected. Only in every aspect of the production process, in strict accordance with the requirements of the production process and operating instructions to ensure product quality.pcb making company On the "PCB circuit board quality is produced or tested" this topic has been the focus of debate in the business community: producers say that the quality is tested, poor quality products into the market is the inspector did not put a good pass; inspectors say that the quality of production, the producer if you do not produce substandard products, the market! There will be no inferior products on the market! Is it, this is a fruitless debate?
Well, PCB circuit board product quality in the end is produced or tested?
First of all, we have to analyze the first and second, active and passive relationship. As we all know, the production of products before the test in the future, in other words, only Mr. output products, in order to test, if there is no product there is no way to test,multilayer pcb how come the results of the advantages and disadvantages?
Obviously: production is active, inspection is passive. "Product quality is produced, not tested" before this concept, the early quality management is limited to quality inspection, only the quality of the product after the implementation of the gatekeeper.
Only in every aspect of the production process, in strict accordance with the requirements of the production process and operating instructions to ensure product quality. If you ignore the process control, only rely on inspection, it is impossible to ensure product quality,PCB board china because the quality inspection, can only eliminate defective and waste products, and can not improve product quality. In other words, the focus of quality control must not be placed on the aftermath of the gatekeeper, but must be placed on the manufacturing stage, that is, the production process stage.
Why are there quality problems?
Product development before the problem is not dealt with, mass production through rate is too low, we hope to rely on the quality of the fire, want to rely on improving the frequency of testing, from which to reduce defective or substandard products; add rework materials, unqualified materials, but no prior testing and verification, there is no accurate product quality fluctuations in the perception of the situation; the customer rushed to the goods, the above pressure, the boss according to their own so-called practical experience to speak, for products that are not in the standard range, the implementation of special release! For products not in the standard range, the implementation of special release, resulting in product problems; the industry has improved the quality standard of the product, the company is still in accordance with the original standard production; production process of non-human quality problems, but not in the frequency of testing range, and so on.
How to control product quality in all aspects?
Products in the design stage on the basic positioning, and then the quality of all rely on procurement, processing and manufacturing, packaging, transportation to ensure that these links are well controlled, the quality of natural control. So product quality is realized in the design and production process, quality is realized through process management. How to control product quality:
1. Establish the quality is the lifeblood of the enterprise consciousness
To realize that the whole staff: the quality of the product is not good, there is no market for the product, there is no market for the product, the enterprise will lose the source of profit, over time, the enterprise will close down, and subsequently, the employees are unemployed. Of course, for the company, even if the product market is good, but also to "be prepared for danger", the quality of the product to do better, to create a better corporate reputation. As the saying goes: "If you bloom, the breeze comes from".
2. Establish the quality of customer awareness
All customer-centric, see themselves as customers, see themselves as the next process operators, see themselves as consumers of the product. In this way, in the work will consciously do a good job, we all do a good job, the quality of the product will be guaranteed, if you cut corners in the work, the harm will be their own personal interests.
3. Establish the quality of preventive consciousness
"The quality of the product is produced, designed, not by inspection, the first time to do things right." This is not a slogan, which well reflects the preventive nature of product quality, if the quality control does not start from the source, it will be difficult to control the quality of the product.
Even if the production of a large number of inspection manpower to check, the production of a large number of defective products or even scrap due to the lack of control from the source, the cost of the product will be greatly increased. Moreover, some product quality problems may not be able to find and make up from the latter process, which requires us to do a good job in the first time to prevent quality problems.
4.Establish the program consciousness of quality
Quality management is the whole process, the whole company, and between the various processes, the company's work between the various departments must be orderly and effective, requiring all quality management personnel, operators strictly in accordance with the procedures, if not according to the procedures of the work of the opportunity for error will increase the quality of the product can not be guaranteed.
5. Establish the sense of responsibility for quality
Quality problems have 80% out of the management, while only 20% of the problem originates in the staff, that is to say, managers can control defects accounted for about 80%, operators can control defects generally less than 20%. In the manager to improve the level of management at the same time, it is also necessary to make the operator to understand the following four points:
The operator knows how and why he does what he does;
The operator knows whether the product he produces meets the requirements of the specification;
The operator knows what will happen if he produces a product that does not meet the specification;
the operator has the ability to handle abnormal situations correctly.
If the above four points have been satisfied and the production of equipment, equipment, testing and materials and other material conditions are available and failure still occurs, it is considered to be the operator's control of the defects; if any of the above four points can not be met or the production of equipment, equipment, testing and materials and other material conditions are not available and failures, it is the responsibility of the management staff. Only understand the responsibility of the quality problem, in order to target to improve the problem will improve the quality.
6. Establish the quality of the continuous development of consciousness
Quality is not the best, only better; quality improvement is a continuous, continuous improvement process, it follows the PDCA model. PDCA model can be briefly described as follows:
P-plan: according to the requirements of the product, to develop improvement plans;
D-implementation: implementation of the plan;
C-Inspection: according to the requirements of the product, the process and product inspection;
A-disposal: take measures to continuously improve product quality.
Only in this way, the quality of PCB circuit board products will continue to rise, and only in this way to continuously improve quality and innovation, will continue to win in the market.
7. Establish the quality of the cost consciousness (i.e., quality standard consciousness)
Ensure quality, the pursuit of profit is the eternal goal of the enterprise. Enterprises to develop, have to focus on the cost of production, but the cost and quality are closely related to the quality of good, can minimize the cost of the product, if the product is not good quality, often returned by the customer complaints, then his cost will remain high, and even forced the enterprise to the brink of extinction. The reason for the decline of many enterprises: not because there is no source of customers, no orders, but because of the internal management of the enterprise is not good, the cost can not come down and can not participate in the market competition, the enterprise should be warned.
But the quality is not the more strict the more favorable to the enterprise. On the contrary, excessive improvement of product quality will result in excess quality and also increase production costs. So we are in the production, the requirements of the various processes and links in strict accordance with customer standards to do, so that we can minimize costs and improve the competitive advantage of the market.
8. Establish the educational consciousness of quality
Along with the development of the times, the concept of quality management is also constantly being updated and needs to be learned. Successful enterprises in the twenty-first century will belong to those who learn and grow enterprises, strengthen internal training to improve the ability of all staff to work and innovation, will make the enterprise thriving, changing day by day. So it is said, "Quality begins with education and ends with education." Facts have proved that those successful enterprises are in accordance with the "product is produced" concept of strict product production, they strictly control every aspect of product production, to ensure that the quality of each link is not wrong, a ring close to a ring, so that the production of products is qualified products, to withstand the test of the market.
