       Circuit Board process technology is developing very fast, and each different PCB manufacturer uses different process technologies. Different types and requirements of circuit board also need adopt different manufacturing techniques, but in these different techniques, there are many essential basic processes that are similar. So, what are the essential processes when manufacturing circuit board? 1. Basemap Film Manufacturing Board The basemap film determines the pattern to be configured when circuit board is manufactured. Moreover, no matter which technical method is adopted in the production process of the circuit board, it is necessary to use a base film film which meets the quality requirements. Therefore, the basemap film is an important tool when manufacturing circuit boards, and it is also the first step in manufacturing techniques.     2. Pattern Transferring After manufacturing the baseboard, transfer the designed circuit diagram to the copper-clad laminate. This process

        Reflow soldering is a soldering technology developed with the emergence of miniaturized electronic products. It is mainly used in the soldering of various surface mount components, and has become the mainstream of PCB assembly technology in PCBA factory. So what advantages does it have?   1. When PCB manufacturers perform reflow soldering, the components are not directly immersed in the molten solder, so the thermal shock to the components is small.     2. PCB factory can control the amount of solder applied in the leading process to reduce soldering defects such as virtual soldering and bridging. Therefore, the welding quality is good, the consistency of the solder joints is good, and the reliability i s high.     3. If the position of the solder on the PCB is correct in the pre-process, but the position of the component is deviated to a certain extent, and in the process of reflow soldering, when all the solder terminals, pins and corresponding pads of the components are infi

       We found that the circuits on the board were all bent. Why should it be designed like this? Do you know the answer? First, if the circuit in the manufacturing of the circuit board is designed to be straight, the area of the circuit board will increase several times. In this era of pursuit of exquisiteness and compactness, the area of the circuit board must be as small as possible, otherwise it will directly affect the area of electronic products. At present, most people's requirements for electronic products are: the larger the screen, the lighter the weight, the smaller the volume and the thinner the thickness.     Second, even if we don’t care about the size of the circuit board and design the circuit in the circuit board to be straight, it will cause other problems. In a circuit board, the circuit must be turned. If we designed the circuits in the circuit board to be straight, the angle of this turn would be 90 degrees. Because the circuit easily generates a large reflect

      Nowadays, PCB wave soldering has become the most commonly used process method for soldering circuit board. This method is suitable for soldering printed circuit boards with discrete components and integrated circuits on one side in batches and in large quantities. So what are the advantages of PCB wave soldering?   Working Principle: Wave soldering uses a mechanical or electromagnetic centrifugal pump in the solder bath to press the molten solder to the nozzle , forming a smooth upward wave of solder and continuously overflowing from the nozzle.   The printed circuit board equipped with components moves through the  wave  solder ing   in a plane and straight line at a uniform speed, forming infiltrated  solder joints on the soldering surface to complete the soldering.     Advantages: 1.  A layer of antioxidants floats on the surface of the molten solder to isolate the air .  As long as the wave soldering is exposed to the air and the chance of oxidation is reduced, the solder was

       What is lamination? Lamination is a forming process that combines multiple layers of the same or different materials under heat and pressure. The whole process of lamination includes Kiss pressure, full pressure and cold pressure.  So what should be paid attention to during the lamination process?       1. In terms of design, the thickness, dimensions and positioning holes of the inner core board must be designed in accordance with the requirements of lamination.  In general, it is required that the inner core board has no open circuit, short circuit, no oxidation, and no residual film.     2. When laminating multi-layer boards, we need to process the inner core board. The treatment process includes black oxidation treatment and browning treatment. Oxidation treatment is to form a black oxide film on the inner copper foil, and browning treatment is to form an organic film on the inner copper foil.     3.  In the lamination process, we need paid attention to 3 problems: temperatu

       When you see a super-looking keyboard, do you want to assemble it yourself? Before we doing it,   let ’ s  learn about relevant knowledge   so that   we   can get started with assembly faster.         Let's first understand, a mechanical keyboard as a typing tool, what does it need to have in order to make it work properly?   It needs to have at least: shell, PCB board, positioning plate, keyboard shaft body, keycap, satellite shaft.   The shell is used to carry the PCB board, the PCB board is used to realize the function, the keyboard shaft body is used to trigger the PCB board, and the keycap is used to adapt to finger tapping on the shaft body. The above four parts are  indispensable. With these four parts, it can work normally when the data line is connected.     The keyboard PCB is the heart of the keyboard. Therefore, when we choose a PCB, we must consider the following: 1. Compatibility with mechanical switches There are two types of mechanical switches, namely 3-pin

      Antennas are an integral part of communication systems, they transmit signals from a transmitter to a receiver, or from a receiver to a transmitter. PCB antennas, FPC antennas, and LDS antennas are all common built-in antennas, each with its own advantages and disadvantages, and suitable for different application scenarios.       1.  PCB  A ntenna PCB antennas are mainly used on single-band module circuit boards such as Bluetooth modules, Wifi modules, and ZIGBEE modules.   Advantages: 1)  It cost is low; 2)  Only need to debug once, no need to debug again.   Disadvantages: 1) It is only suitable for single-band module circuits; 2) Different batches of PCB antenna performance will have a certain deviation.     2.  FPC Antenna      FPC antenna is an antenna made on a flexible PCB. Unlike PCB antennas, the flexibility of FPC antennas allows them to be bent and folded, allowing them to be used in various shapes and devices that are too small.  It is usually used in low-end mobile ph

       Perhaps, those who do not have a deep understanding of the PCB industry do not know the difference between PCBA and SMT. So, this article will takes you through the differences between them.       PCBA and SMT belong to the inclusion relationship. Among them, PCBA refers to the entire process technology from PCB to SMT assembly or DIP, and SMT is only an assembly process technology in the PCBA processing process. Therefore, it can be said that PCBA includes SMT,  and then let us take a closer look .     1.  SMT SMT, or Surface Mount Technology, is a mounting technology of electronic components. Compared with traditional contact pin and socket connection method, SMT can directly install components on the surface of PCB, and connect the components to the PCB through welding and other processes. First, put the components on the corresponding positions of the PCB, and then the pins of components are connected to the pads or solder balls of the PCB by a welding machine or manual weld

       Whether it is medical testing equipment or medical auxiliary equipment, it needs to have a very high  accuracy  under the premise of use, because  things  related to  life cannot be  vague or inaccurate .  So when medical PCB in processing, what should we paid attention to?       1.  Quality Control of Components The control of Medical electronic components should control the quality from the source of procurement. After the purchase is completed, IPQC is required to conduct a full inspection of components and seal the samples in to the storage. Special BGA, IC should be stored in a moisture-proof cabinet.     2.  Solder Past Control The PCB processing of medical electronics requires the selection and storage of solder paste according to the characteristics of the product, and the stirring and adding of flux during use need to be strictly controlled.     3.  Solder Control Medical PCB processing requires soldering operations, and the soldering temperature and time must comply wi

      In our life, PCBA is widely used. In particular, the development of medical technology has benefited too many people, and it is mainly due to the improvement of SMT technology, which can promote the maturity and stability of PCBA control boards. So why does medical PCBA processing require ISO13485 qualification certification?       1.  The manufacturing process of medical PCBA involves a variety of medical electronic equipment and materials, such as sensors, displays, electronic components, connecting wires, etc.  The quality of these devices and materials directly affects the quality and safety of medical device. The ISO13485 standard puts forward detailed requirements and standards for the production process of medical PCBA processing, including production equipment, raw materials, technological process, quality control, etc., to ensure the quality and safety of medical PCBA processing.     2. The quality and safety of medical devices is one of the key factors  affecting  the
