          As electronic products become increasingly miniaturized and complex, the accuracy and reliability of PCBs have become crucial factors in determining their survival and development. In this intricate process, there is a seemingly inconspicuous yet critically important component — the peelable mask.  Although it  may  not as eye-catching as chips or components,   the peelable mask  plays a vital role in the production and protection of PCBs.   What is PCB  Peelable Mask ? PCB peelable mask is a special adhesive material that often used in PCB manufacturing process and appears blue or light blue. It mainly used to protect, secure and insulate specific areas. For many high-precision PCBs, the use of peelable mask directly  affects the product yield and performance.     Four  C ore  F unctions of   Peelable Mask 1.

        PCBA processing will be significantly and profoundly affected by artificial intelligence, and these technologies will have important potential in the following aspects:   1. Automated  P roduction   L ine Please imagine that with the help of artificial intelligence, robots are   running back and forth   on the PCBA processing assembly line like busy ants, completing tasks for us with millimeter  accuracy.   They can place components more accurately than manual operations and improve production efficiency.     2.  AI  Q uality  C ontrol Artificial intelligence is applied to product quality control, identifying and correcting defects that may occur in the manufacturing process through technologies such as image recognition, machine learning, and deep learning. This helps reduce the number of defective products, thereby improving the reliability and quality of the product.     3. Predictive...

       In  PCBA factory , in order to prevent components from falling off or shifting during the wave soldering process, it is often necessary to use SMD adhesive to fix the components on the PCB board.  So what should you pay attention to when using  SMD Adhesive  in PCBA processing?   1)  The purchased  SMD  adhesive should be placed in a refrigerator below 5°C and stored in a low-temperature seal.  And do a good job in registration, pay attention to the production date and service life. It is also necessary to note that large quantities of incoming goods must pass inspection before they can be put into storage.     2)  After taking it out of the refrigerator during use, it should be restored to room temperature for 2 to 3 hours to allow it to equilibrate with room temperature before opening the container to prevent the SMD adhesive frost from absorbing moisture. Please pay attention to the type and viscos...

In PCBA factory , flux is an indispensable auxiliary material in the welding process. The quality of the welding effect is not only related to the quality of the welding technology, components and printed circuit boards, but also the selection of flux is very important. Do you know how to choose flux?   1. Performance requirements for flux 1) The flux need to have the characteristics of removing surface oxides, preventing re-oxidation and reducing surface tension, which is the basic performance that the flux must have.     2)  The melting point should be lower than the solder.   Before the solder melts, the flux must melt first to fully exert its fluxing effect.     3) The wetting and diffusion speed of flux is faster than that of molten solder.     4 ) The viscosity and density of flux are smaller than that of solder. A high viscosity will make wetting and diffusion difficult, and a high density will not cover the solder surface.   ...

        In the PCBA factory , testing is required after PCBA processing is completed. Its purpose is to test whether each function can operate normally by simulating various operations and environments of the product in actual use. Do you know what tests are required after PCBA processing?   1.  Electric Test Testing personnel will use special testing instruments to check various circuit on the PCBA.  By applying the appropriate voltage and current, testing personnel can determine whether the circuit is connected correctly and whether the electrical performance is normal.  This step is essential to ensure the safety and stability of electronic products.     2.  Communication Test For electronic products that need to communicated with other devices, testing of communication functions is essential. Testing personnel simulate various communication scenarios, such as network, Bluetooth, WiFi, etc., to verify whether the product can comm...

       PCBA factory will encounter some special components during processing, such as moisture sensitive components. The impact of such components on processing is no less than ESD, so it is necessary to strengthen the storage and use management of moisture sensitive components. So how should PCBA factories correctly handle moisture sensitive components?       PCBA factories can store moisture sensitive components reasonably to avoid damage to components due to moisture absorption of moisture sensitive components. Therefore, the defect rate of the product can be reduced, and the reliability of the product can be improved.     In actual processing, for moisture sensitive components that are affected by moisture are generally baked according to the baking conditions in the warning label on the original packaging bag of the manufacturer. For component manufacturers who do not have corresponding requirements, it is recommended to use high-tempera...
