What are the bad factors of the pcba board processed by SMT?

In the process of making pcba board, SMT processing is especially important, and the process is also the most prone to the defects of pcba board, especially the advanced level of equipment, manual operation method and air environment. Let's talk about some of the bad factors that arise during the processing of smt? 

More than 48% of the SMT processing defects are from the printing process, and play an important role in front-end basic printing technology. 90% of Smt processing board printing defects are caused by poor solder paste mixing; Jingbang smt processing factory introduced Japan's advanced planetary centrifugal solder paste mixing technology, which has solved the problem of solder paste and solder paste printing for electronics, optoelectronics and other major enterprises. The resulting bad, which greatly improved the quality of the company's products and work efficiency. 

The following are the adverse factors that are affected by the lack of solder paste in the smt process. 

1, the poor solder paste and tin powder uniformity is not enough, resulting in poor soldering! 

2, bad solder paste is not sticky enough, tin powder flux components volatilize, easy to drop or device offset when mounting! 

3, the solder paste contains air bubbles (air), tin blast and sand holes when welding; 

If you encounter any technical problems during the smt processing, please consult Shenzhen Senruida Mounting Technology Co., Ltd., for details! 

Customer requirements for SMT chip processing suppliers

Customers who generally need to develop or process projects will review the “quality and production capacity” of smt chip processing manufacturers. Therefore, the quality requirements for smt patch processing are as follows. 

1. Brands In general, suppliers of SMT chip processing with strong brands are the most difficult for customers, and they also establish a long-term stable development relationship, which not only saves procurement time, reduces procurement costs, but also reduces them. For quality inspection procedures, a strong brand can simply confirm the product's label. However, the price of a branded product is usually higher, and it is more advantageous to use the brand method when purchasing a small quantity. 

2, production capacity, in order to get more recognition, not only in the customer's first proof of quality standards, but also in the future batch strict control quality, to do the same materials, different levels. 

3, professional cooperation, in the advanced development of equipment, the efficiency of your production can meet the customer's delivery, and price and quality controllability. 

4, material quality and manufacturing method specifications: a lot of smt patch processing manufacturers in order to reduce costs, at the cost of discontinuing the sacrifice of quality, do not carry out 9 quality inspection (online AOI, x-ray optical instrument detection, etc.) means . In order to win the leading company in the industry, we must do the first positioning of quality, service and production methods to make a more perfect finished product. 

5, smt patch processing factory management and employees' mental outlook: the frontline staff and management of the standard operation determines whether the customer's products have high quality, pass rate, etc., because pcba's products are the management of employees and The operating equipment is produced together. Therefore, the employee spirit of smt manufacturers is very important. 

6, look at the price: the first step of cooperation, is your reasonable price, is to play a mutually beneficial and win-win role, but the initial price and the final price are negotiable. After all, quality and price are directly proportional. 

7, playing samples: proofing is also the first impression of smt patch processing manufacturers on the development of customers is also the first level of quality assessment, only to do a good job, in order to establish a stable long-term cooperative relationship. 

The above is the view of some customers on the supplier.
