  5G communication is a huge and complex integrated technology, and its challenges to the  PCB process   are mainly focused on: large size, multilayer, high frequency, high speed, low loss, high density, rigid-flex combination, high and low frequency mixed pressure, etc. So many process technologies put forward new or higher requirements for PCB materials, design, processing, and quality control. PCB companies need to understand the changing needs and propose comprehensive solutions. Material requirements:   A very clear direction for  5G PCB   is high-frequency and high-speed materials. In terms of high-frequency materials, it can be clearly seen that the leading  PCB material   manufacturers in the traditional high-speed field in China have begun to deploy high-frequency plates and introduced a series of new materials. This will break the current dominance of foreign brands in the high-frequency sheet industry. After healthy competition, the per...

As PCB design   is more and more commonly used with existing development boards, and daughter boards are used to drive hydraulic devices and servo motors or perform tasks based on light, motion, and sound, the trend of PCB design gradually tends to open source hardware models and Control System. After completing the product and printed circuit board design , you need to start building prototypes before mass production of PCBs. Several PCB design software packages, such as printed circuit board layout design tools and individual design tools, have simulation capabilities. Doing so can minimize the number of design errors before building the main PCB prototype. If you are designing a complex project, you may need to consider a modular design in which all the main functions are located in separate modules. During the inspection, modules that do not meet the design constraints can be exchanged. Rotating a single module is faster and more efficient than rotating the entire design. All o...

  In recent years, resin plug holes   have beco me  very popular in the  PCB industry   and have a wide range of applications.  Especially  some products with high layers and thick boards have a higher use rate of resin plug holes. So what is a resin plug hole? What are the benefits?   What is a resin plug hole?   With the continuous change and reform of electronic chip structure and design methods, circuit board modules have also undergone great changes. With the change of modules, the problem of green oil plugging in electronic chips has deeply troubled many  smt  processing manufacturers . In order to solve this problem, many  pcb engineers   have put in research efforts until the 1990s,  a Japanese  pcb manufacturer   invented resin, which can plug this kind of hole, and then plate copper on the surface, which can solve the problem of blowing in the hole caused by the green oil plug hole. However, the te...

  1. Expired PCB may cause oxidation of the solder pad on the PCB surface Oxidation of the soldering pad will cause poor soldering, which may eventually lead to the failure of the PCB function or the risk of dropping parts. Different surface treatments of  circuit boards  will have different anti-oxidation effects. In principle,  ENIG  requires it to be used up within 12 months, while  OSP  requires it to be used up within six months. It is recommended to follow the shelf life of the PCB board factory. OSP boards can generally be sent back to the board factory to wash off the OSP film and re-apply a new layer of OSP, but there is a chance that the copper foil circuit will be damaged when the OSP is removed by pickling, so it is best to contact the board factory to confirm whether the OSP film can be reprocessed. ENIG boards cannot be reprocessed. Generally, it is recommended to perform "press-baking" and then test whether there is any problem with the ...

  The first piece of   PCBA   processing is produced because the previous technology and equipment are not as mature as they are now. The factory often has poor batches, repairs, and even scrapping during the production process. The first piece is the product that will need to be processed in batches. . Mass production can only be started after all tests of the first piece test have passed. Under what circumstances need to do the first inspection of PCBA processing 1. New product processing for the first time 2. Change product model 3. Adjust the equipment 4. Adjust process methods and technical conditions 5. Use new materials or equipment The necessity of the first inspection of PCBA processing 1. The first inspection of PCBA processing is mainly to prevent batches of out-of-tolerance, repair and scrapping of products. It is a means to control the production process in advance and an important guarantee method for product process quality control. It is circuit board manu...

At present, in the electronics industry, the application range of PCB circuit boards is very wide. A good PCB circuit board can not only improve the stability of electronic products, but also optimize the overall product. However, due to fierce market price competition, the cost of PCB board materials is also on a rising trend, and more and more manufacturers are monopolizing the market with low prices in order to enhance their core competitiveness. The low price means that the cost of the material is reduced. The process is simple, and the more problems of the PCB appear. How do we identify the advantages and disadvantages of the PCB? First,  the circuit design aspect.  A good quality PCB circuit board must have a good circuit design. Whether it is a double-sided board or a multi-layer board, it must have precise line control and reasonable line trend in order to avoid slow response due to messy lines. The second aspect is the appearance.  Pcb surface appearance: Good qu...

  Green is more convenient for pcb production Compared with other colors, the green series has better characteristics, especially the green plug hole characteristics. It may be better to realize the plug hole in the IC Test Board design. Basically, there will be plug holes, hundreds to thousands of them. Combined with the taiyo ink characteristics table, it is also clear why green can be made with high precision, which is also determined by the characteristics of green. Green PCB is cheaper For a purchaser, it is his job to reduce costs. Since green is the mainstream color in the production process, the purchase amount of natural green paint will be larger, and it can be concluded that the purchase cost of green paint will be lower than other colors. At the same time, the use of the same color paint in mass production can reduce the replacement cost. The  pcb manufacturer  defaults to green ink, and changing to other colors needs to increase the cost. The characteristics ...
