For any SMT patch equipment, as the technology is updated and the service life increases, the machine will experience wear and tear or component wear and looseness to varying degrees. As well as some external factors, incomplete replacement of lubricating oil inside the machine, dust caused by improper environmental control, moisture and oil in the gas line, etc., will affect the normal operation of the machine, cause parts to wear to varying degrees, and even lead to accidents, so SMT patches Equipment must be maintained regularly.

PCB paneling is a combination of several small PCB units through various connection methods. In the process of panel design, designers will consider product structural dimensions, electrical performance, component layout, etc., so will PCB panel design affect PCBA processing production efficiency? The answer is yes.

During the PCBA processing process, there will be various testing links, which can check whether the reliability of the PCBA board can meet the factory requirements. Therefore, the testing process will directly affect the customer’s recognition of the factory’s quality. So what tests will the PCBA factory conduct on the product?

Moisture is the most common and destructive factor to PCB circuit boards. Excessive moisture will significantly reduce the insulation resistance between conductors, accelerate high-speed decomposition, reduce the Q value, and corrode conductors. Currently, there are three main types of three-proof processing technology that I know about PCB circuit boards: three-proof paint, electronic wax, and nano-coating.

Waste circuit board detection, waste circuit board recycling, and waste circuit board refining technology are technologies that benefit the whole industry. The sources of raw materials available are endless.

In the PCBA processing quotation process, the quotations given by various suppliers are either high or low. Then choose a suitable PCBA processing factory based on factors such as delivery time, quality, and after-sales service. So do you know how PCBA processing costs are calculated?

During the PCBA processing process, you will hear from colleagues PCB boards and FPC soft boards. FPC soft boards generally require fixed fixtures during processing, and subsequent AOI inspections also require fixed fixtures for inspection. So what is the difference between PCB and FPC?

With the rapid development of the electronics industry, more and more attention is paid to the shelf life of PCBA. Under normal circumstances, the storage time of PCBA is about 2-8 years. So what are the factors that affect its shelf life?

As we all know, the printing process is the source process of PCBA processing, and the quality of printing will directly affect the welding quality of the product. So what factors will affect PCBA printing quality?

In the PCBA processing process, patch components and plug-in components will be used. SMD components are printed on the PCB board with solder paste and then solidified by reflow soldering. DIP plug-ins insert the components into the PCB board holes with a DIP structure. So what’s the difference between the two?

For the PCB electronics industry, according to industry surveys, the most fatal weakness of the chemical tin plating layer is that it is easy to change color (easy to oxidize or deliquesce), poor solderability makes it difficult to weld, and high impedance leads to poor conductivity or poor performance of the entire board. Stable and easy to grow tin whiskers, causing PCB circuit short circuit and even burning or fire.

With the widespread use of micro electronic products, the size of electronic components is getting smaller and smaller. SMT chip components are divided into three categories according to their functions: passive components, active components and electromechanical components.

The rapid development of the electronics industry has resulted in electronic products becoming more and more powerful and smaller in size. High integration means that unit circuits are getting narrower and their ability to withstand electrostatic discharge is getting worse. At the SMT patch production site, anti-static areas will be set up in the production, use, maintenance and other environments of electronic products. So what is the purpose of anti-static?

As we all know, anti-static work areas will be set up at SMT patch production sites, such as product repair parts, testing laboratories, etc., to protect electronic products as much as possible and avoid defective products caused by electrostatic discharge. So what are the anti-static facilities management at SMT patch sites?

With the rapid development of the electronics industry, SMT involves a wide variety of parts, many of which have formed common standards in the industry, especially IC components, whose packaging forms are constantly changing. So what is electronic component packaging?

AOI testing equipment is an automated testing equipment controlled by a computer that integrates light, electricity, gas and machinery. AOI equipment uses the reflection of light to detect whether PCBA components are mounted correctly, the mounting position, whether electronic components are missing or reversed, etc. It only performs appearance inspection. AOI equipment is divided into AOI offline and online detection, so what is the direct difference between them?

With the rapid development of the electronics industry, there are more and more PCBA factories. Many customers choose factories based on comparisons in terms of delivery time, quality, price, etc. When choosing a PCBA factory, what aspects of the factory need to be inspected? How to choose a strong factory?

PCBA program design, is to convert the customer’s ideas into a concrete program can be implemented, in order to quickly and reliably bring the product to market, the program development and design process becomes Especially important. So how is the PCBA program design process?

Dianjing Technology has been committed to providing high-quality PCB design and one-stop electronic engineering for more than ten years, winning customer trust with highly competitive prices and quality services. Then the editor of Dianjing will introduce to you the eight steps to make a good PCBA solution.

Initially in the SMT industry, after reflow soldering, the finished products processed by patch panels had no appearance damage, but the yield rate was very low. Baking at too high a temperature will change the internal structure of the product; baking at too low a temperature will cause the product to fail to melt tin and fail to complete welding. The concept of temperature control appeared, and furnace temperature testers were also widely used. Then the editor of the PCBA manufacturer will introduce to you the role of the furnace temperature tester.

As integrated circuit technology continues to advance, the requirements for integrated circuit packaging are becoming more and more stringent. I/O pins have increased dramatically, and power consumption has also increased. In order to meet market demand, ball grid array packaging – BGA packaging has appeared. So what are the characteristics of this package? Let the editor of the PCBA manufacturer tell you.

After the automatic placement machine has been running for a long time, the inside of the machine will be more or less worn, aged, and deformed, which will greatly affect the placement accuracy of the machine. Therefore, the machine must be maintained and maintained regularly, and the relevant parameters must be calibrated to ensure that the fully automatic placement machine operates at its best and produces high-qualification PCBA products.

With the rapid development of the electronics industry, electronic products have become more intelligent and miniaturized, and PCB industrial technology has also ushered in major reforms and progress. So what are the advantages of PCB multilayer boards? Let the editor of the PCBA manufacturer popularize this knowledge for you.

Many people may not know much about PCBA solution design. The engineering R&D team of major PCBA design and processing companies converts customer ideas into feasible and specific solutions, optimizes the solutions, manufactures products, and finally converts customer ideas into physical products. So what is the specific program design process?
