       In the  PCBA factory , the BOM  list  is like a secret book that records in detail the information of all components and materials used on the PCBA, such as the name, model, quantity, supplier information, etc. of the  component s.  It has a decisive influence on every link, no matter how big or small.   1.  Component Procurement For PCB manufacturers, the BOM  list  is like a compass that points the way.  It lists in detail the core parameters of each component that needs to be purchased, such as component model, quantity, supplier information, etc.   This helps ensure purchasing staff get exactly the components they need and avoid material shortages or incorrect purchases.     2.  Production Plan The BOM list is a powerful tool for assembly engineers.  It can help them clarify every aspect of the assembly process and clarify which components should be placed on the PCB when, ensuring ...

        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...

       In PCBA factories , the selection of equipment plays a vital role in ensuring the quality of PCBA. Correct selection and use of equipment can improve production efficiency, reduce defective rates, and ultimately provide customers with high-quality products. Do you know what equipment can ensure the quality of PCBA?   1.  SMT  M achine SMT machine is the one of the most important equipment.   Its main function is to pick up components from one location and place them accurately on the PCB board.   The accuracy and stability of the SMT machine are crucial to the quality of PCBA. High-precision SMT machines can accurately place components at designated locations to avoid errors and  error accumulatio n.  SMT machines with higher stability can maintain accuracy during high-speed production and improve production efficiency.  Therefore, when selecting a SMT machine, factors such as accuracy, stability, and production speed ne...

       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...

      PCBA conformal   coating   is a kind of protective coating, which will form a transparent protective film after curing to protect PCBA from environmental erosion.   PCBA  factorie s generally classify the types of PCBA conformal coatings according to the solvent content.       1.  Solvent -based   Conformal  Coating Solvent-based conformal  c oating  is a coating made of organic solvents as a dispersion medium, and it is also the type of conformal  c oatings used most by PCBA  factorie s .   Solvent-based conformal   c oating   has the advantages of good protective effect, cheap price, and easy repair. Its disadvantage is that it contains volatile toxic gases.     The solvent types of solvent-based conformal coatings mainly include hydrocarbon solvents, oxygen-containing solvents and water solvents. 1.  Hydrocarbon solvents are mixtures of materials of different molec...
