The quality problems of high-frequency boards/circuit boards generally include short circuit and open circuit, green oil blistering, green oil falling off, substrate delamination, board warpage, pad falling off, poor tinning, and open circuit after aging. The fundamental reasons for these common high-frequency board quality problems are that the production process of the high-frequency board factory is not up to standard, the production equipment is outdated, the selection of raw materials is poor, and the management is chaotic.
Reason 1: The selection of raw materials is cheap and inferior: the quality of raw materials is the cornerstone of the quality of the circuit board. What is more hidden now is that the materials used by some high-frequency board/circuit board factories are mixed, some are genuine boards, some are scraps, or recycled materials to dilute the cost. The hidden danger of doing this is not knowing which one There will be problems with batches. Due to the different use characteristics of circuit boards, some high-frequency boards/circuit boards do not have high requirements, so some scrap materials do not show obvious problems in such occasions, which makes many high-frequency board/circuit board factories like this At the same time, because of the low price, it also won the preference of customers. It also encourages high-frequency board/circuit board manufacturers to continue to take such risks. In the long run, if the quality of the finished product is caused by the substrate problem, it is often a huge loss, and sometimes it is impossible to restore the company's reputation and brand. This is also the reason why regular circuit board manufacturers do not do this.
Reason 2: Management confusion: The high-frequency board/circuit board factory has many production processes and long cycles. How to achieve scientific and orderly management and reduce management costs at the same time is a difficult problem. Cheap, which requires long-term accumulation of circuit board manufacturers. With the advancement of science and technology, especially the development of the network, it has become possible to manage the traditional high-frequency board/circuit board factory by means of network informatization. Only by making breakthroughs in this regard can core competitiveness be formed. For a factory with poor management, the quality of its circuit boards will naturally fluctuate frequently, and various problems emerge one after another and recur repeatedly.
Reason 3: The production equipment is backward: the equipment is to ensure the quality from the hardware, increase the investment in the equipment, and make the equipment efficient and stable is the fundamental way to improve the quality of high-frequency boards/circuit boards. With the advancement of science and technology, the replacement of circuit equipment is getting faster and faster, the equipment is more and more advanced, and of course the price is getting more and more expensive. This has led to the inability of some small high-frequency board/circuit board factories to add more expensive equipment, resulting in increased dependence on employees. The current labor cost is already high. Once the dependence on skilled and skilled employees is formed, the management difficulty of the high-frequency board/circuit board factory will be greatly increased. Once there is a flow of personnel, the quality of the high-frequency board/circuit board will fluctuate. .
Reason 4: The production process is not good enough: The production and processing of high-frequency boards is a relatively high-tech industry, involving a series of interdisciplinary subjects such as electroplating, chemical industry, machinery, etc. Each process of high-frequency board production and processing must be implemented in accordance with strict production processes. At the same time, each process must be equipped with corresponding testing and laboratory equipment. These process parameters and equipment can ensure the stability of the quality of high-frequency boards/circuit boards. It is undeniable that the circuit board industry is also a polluting industry. Many practitioners and even bosses who enter this industry are half-way out, so many small high-frequency board factories only care about the price, as long as the cost can be reduced, in the production process and high-frequency boards. Don't care about the quality at all. The concentration of the potion in the electroplating process is a parameter that changes all the time. Different types of high-frequency boards/circuit boards have different current sizes and times of the electroplating process. These parameters are combined to affect the quality of high-frequency boards/circuit boards. Only strict production process guidance, production according to process parameters, and continuous laboratory inspections can ensure that the quality of the produced high-frequency boards/circuit boards is always in a stable state. If the production is organized by experience, there is a quality problem, and the potion is added by feeling, which directly leads to the constant fluctuation of the quality of the high-frequency board/circuit board. Customers using this high-frequency board/circuit board will have a high repair rate and the finished product The rate is low. On the surface, the purchase cost of the circuit board seems to be reduced. In fact, the maintenance cost of maintenance and repair is greatly increased. At the same time, the customer brand is affected, which is not cost-effective in the long run.
