Patch processing plant which good how to judge

The solid content and coating amount of flux will also determine the wash-free effect of the pad. In order to achieve this effect, smt OEM will strictly control these two parameters in the production process. The main component of flux is rosin, and rosin will decompose only at about 280 degrees. Therefore, in terms of the temperature of the tin furnace, it is necessary to ensure that the temperature is not too high. In addition, the role of flux is very important, so in the selection can not be careless. So, how to choose a flux? The following patch processing manufacturers will explain how to choose flux in patch processing and how to judge the relevant knowledge of the patch processing factory.

1. How to judge which patch factory is good

Because the profit of the patch processing industry is not low, many medium and large enterprises will quietly mount the SMT production line in order to meet the production needs, which leads to the uneven quality of the patch processing industry, so that the demand enterprises in the selection of difficulties. So, in the numerous Huizhou patch processing plant which is the best? Below, Xiaobian from three aspects for you a simple analysis.

1, the degree of professionalism

The relationship is very important. Some people think that it is the Huizhou patch processing plant, as long as the production is on the line, the management of professional what. SMT processing is a very important link, whether the degree of professionalism is high or not, related to whether the product can be delivered on schedule, quality, good rate, repair rate, etc., these are very important to the enterprise. A simple example is that PCB board produced by a less professional processing plant can barely be used, but after it is put into the production and production of electronic products, its performance will be greatly reduced and the repair rate is very high. In this way, not only consumers dislike it, but also the enterprise will have a headache. Especially in the era of fierce competition, any detail is not handled well. Could lose a lot of customers. Therefore, the degree of professionalism is very important. So, how to investigate the professional degree of Huizhou patch processing plant? We can start from the perspective of employees. For example, we can talk with the boss, management and grassroots employees of the processing plant to see their working attitude and philosophy, and learn about their reputation through a third party. In this way, we can avoid finding unprofessional processing plants.

2, quality control

In order to attract customers at low prices, some SMT factories will take the risk of reducing quality to ensure their own interests. And the quality is reduced, the impact on the future is very big. Therefore, for the quality control of kingford patch processing plant, we must understand clearly. The method is very simple, you can investigate on the spot, and understand its warehouse IQC, furnace after inspection, QC, AOI equipment is reasonable, normal open and use, etc., these are the key points to judge the quality control effect.

3. equipment

Many people in the consultation of kingford patch processing plant which is good, often will first look at the advanced equipment, this is worth advocating. You know, the more advanced the equipment, the higher the production efficiency, the better the quality of the final product. And backward equipment, not only affect the production efficiency, but also reduce the quality of the circuit board. Therefore, when choosing a good processing plant, we must see how the other manufacturer's equipment is.

Friendly tips: some electronic enterprises in the choice of  patch processing plant, often value the scale. For this point, Xiaobian is not very advocate, because some processing plants, although small, but strong targeting, can meet the production needs, in this case, there is no need to force the scale. On the other hand, we should pay special attention to the fact that demanding scale can lead to increased costs.

2. How to select flux in patch processing

In patch processing, the material that must be used is flux. It is to promote the welding of the material, in the welding process, has an irreplaceable role. The solid content and coating amount of flux will also determine the wash-free effect of the pad. In order to achieve this effect, smt OEM will strictly control these two parameters in the production process. The main component of flux is rosin, and rosin will decompose only at about 280 degrees. Therefore, in terms of the temperature of the tin furnace, it is necessary to ensure that the temperature is not too high. In addition, the role of flux is very important, so in the selection can not be careless. So, how to choose a flux?

First, combined with product selection

smt OEM points out that each product has its own characteristics, which is the first factor that must be considered when choosing flux. If this aspect is not taken into account, it is likely to lead to the purchase of the flux can not be used. Therefore, to choose the flux according to the product. General computer peripheral products and motherboard, high precision products, choose high-grade free cleaning flux. Mid-range products choose no halogen or halogen content of less rinse-free flux. This can ensure that after welding, will not cause leakage, electric signal interference and other conditions. Low grade products are recommended to choose more active prednisone flavor flux, although there are residues, but relatively high reliability.

2. Choose according to customer requirements

Some customers will have their own requirements on flux, so kingford smt patch OEM suggests that before purchasing flux, we should first communicate with customers to see if they have requirements. For example, some customers require full tin, so it is necessary to choose appropriate activity, good wettability flux. Some customers require that there can be no white situation, you need to choose no-cleaning flux. If the customer requires no leakage and other adverse conditions, to consider the halogen content of higher flux. If the customer requirements can not have tin beads, virtual welding, welding leakage, etc., we should choose appropriate activity, wettability can be better flux, and then with a good process, we can avoid these situations.

3, according to the equipment process selection

Equipment conditions will also affect the choice of flux, this is mainly because the process is the key to the selection of flux, such as spray type wave furnace to choose loose flavor flux is not appropriate, foaming wave welding is the best choice of spray flux. In addition, manual tin furnace selection of flux range is wide, but it should be noted that if it is foaming flux to ensure fine particles, uniform size, long duration. In general, flux plays an important role in SMT patch processing. It can not be replaced by other products, so it must be carefully selected. In addition, smt OEM also emphasizes that a good flux contributes to welding and product quality and is selected to ensure its thermal stability, activity and density so as to ensure final production results.
