How to judge the quality of smt red glue

For electronic enterprises, the quality of PCBA board not only determines the quality of electronic products, but also determines the future development of enterprises. Therefore, electronic enterprises attach great importance to the processing of PCBA board. As SMT patch processing manufacturers, in the production process will not be sloppy, otherwise it is difficult to retain customers. Then, how does the smt processing factory ensure the product quality? The following patch processing manufacturers explain how to ensure the quality of incoming material processing manufacturers and how to judge the quality of smt red glue related knowledge.

1. How to judge the quality of smt red glue

Because the SMT industry is more popular, its derivative industries are also very developed, like smt red glue is one of them. Because smt red glue is a necessary material in SMT patch processing, its quality not only affects the effect of SMT, but also affects the quality of electronic products. Therefore, it is very important for enterprises to choose high-quality smt red glue. So, how to judge the quality of smt red glue? Now, let me show you a few ways.

First, according to the use effect to judge the quality of smt red glue. Now there are many manufacturers engaged in the production of smt red glue in the market, and more and more brands. These different brands of smt red glue are not only different in quality, price, but also different in effect. For smt patch manufacturers, good smt red glue can not only ensure product quality, but also improve production efficiency. Therefore, most SMT manufacturers will have fixed suppliers. For some new companies, there are certain difficulties in choosing smt red glue. After all, they do not know which is better, which is problematic, and where is the problem of which smt red glue, so there will certainly be problems in the choice. For this, I have deep experience. The company I worked in before changed four or five kinds of smt red glue within two months at the beginning, but the effect was not good and there would be various problems. At first, I thought it was because of the poor quality of smt red glue. Later, I found that the effect of smt red glue was different because of the different production process. Therefore, in order to avoid buying inappropriate smt red glue, manufacturers will evaluate it after printing. If smt red glue appears bridging, lack of viscosity, collapse, blurring and occurrence of skin, it can be identified that the composition ratio is not good, the particles are too large, the activity is not strong, easy to volatilization and other problems.

Second, according to the situation after welding, the poor function of smt red glue mostly occurs in the process technology and operation problems, and there are few problems in this aspect of smt red glue. The key point to judge is whether there is any missing parts after smt red glue welding, whether there is rubber overflow on the surface, and whether there is corrosion of the board surface.

Third, according to the word of mouth to judge smt red glue market word of mouth is the best way to judge whether a product is high quality, word of mouth is the feedback given by consumers, there is very little fake ingredients. When enterprises encounter a good reputation of smt red rubber products, may wish to buy some try. Of course, good reputation does not mean that it must be suitable for their own enterprises, but also choose other factors to judge, so it is more insurance.

In fact, to judge whether a smt red glue is suitable for their own enterprise, the best way is to try. Most of the time, it is not smt red glue product quality problem, but because the production process is not suitable for our own products, so the problem will occur. Therefore, the author suggests that smt patch manufacturers, when choosing smt red glue, first judge what kind of smt red glue their enterprises need, and then choose according to their own needs. Do not blindly choose, do not choose according to the price, it is easy to lose.

2. How does the manufacturer guarantee the quality

For electronic enterprises, the quality of b not only determines the quality of electronic products, but also determines the future development of enterprises. Therefore, electronic enterprises attach great importance to the processing of PCBA board. As SMT patch processing manufacturers, in the production process will not be sloppy, otherwise it is difficult to retain customers. Then, how does the smt processing factory ensure the product quality? In order to ensure product quality, the manufacturer will take the following measures:

First, strict requirements for technical personnel, technical personnel will go through strict training before the job, to ensure that the master of technical skills after the certificate. At the same time, in the new product introduction stage, technical personnel are required to strictly in accordance with the first material preparation, then programming, after review, installation, detection, confirmation of the steps to operate, any step can not be saved, and in this process, in addition to the technical personnel own operation, but also sent to the supervisor for signature confirmation, the supervisor to determine no problem after the mass production. In this way, although a lot of trouble, but to ensure that there are no problems in the production process, but also to ensure the quality of products, avoid accidental losses caused by inadequate inspection.

Two, QC, QC inspection range is very wide, including the welding of components, PCB board components mounted correctly or not, IC direction, there is no material shortage, etc., these are the content of QC. In addition, the first thing QC personnel do after going to work is to check the PCB station map being produced to see if it can be matched, to ensure that there are no problems, promising reverse direction and other wrong products before the next operation.

Iii. When smt machine operators of incoming material processing manufacturers replace parts or change lines, they must replace parts in accordance with the direction, and then start production and fill in relevant replacement records after the technicians check and confirm that there is no problem.

Four, in the process of product switching, the operator should prepare the material in advance, can not operate while looking for the material, so it is easy to cause problems. The best practice is to check the materials between the SMT machine operator and the printing operator, and then the technical personnel and the operator. After confirming the correctness, one person reads the card and one person looks at the material station. At each time of switching, technicians and QC must check and confirm the PCB that has been pasted for the first time to ensure that there is no problem before mass production. The above is the smt processing manufacturers to ensure product quality means, in addition, there are many other means. From these means can be seensmt processing manufacturers, want to ensure that these equipment perfect, must have a certain strength. Therefore, when choosing , it is recommended to choose professional, regular and strong enterprises, which can not only fulfill orders with quality and quantity guarantee, but also provide after-sales service and help, so that electronic enterprises have no worries. Most importantly, choose a good reputation, good reputation of the manufacturer can long-term cooperation, not only save trouble, more money.
