How to Solve the Defects of Wave Soldering Technology

图片
        Wave soldering is an essential equipment for plug-in soldering of electronic products, but  soldering defects are often encountered due to various reasons during wave soldering. So what is the cause of the defect? How to solve these defects?   1.  Solder Projection Reason: 1) Improper PCB transmission speed; 2) Preheat and low tin pot temperature; 3) PCB transmission angle is small; 4) Bad  wave crest ; 5) Flux failure, poor solderability of component leads.   Solution: 1) Adjust the transmission speed until appropriate; 2) Adjust the preheating temperature and tin pot temperature; 3) Adjust the PCB transmission angle; 4) Optimize the nozzle and adjust the  wave crest   shape; 5) Replace the new flux and solve the lead wire solderability problem.     2.  Pseudo Soldering Reason: 1) Poor solderability of component leads; 2) The preheating temperature is low; 3) Solde...

How to Solve the Defects of PCB Dispensing Technology

       In the PCB production process, sometimes there will be defects such as wire drawing, glue nozzle clogging, empty extrusion, and  component displacement . So what is the cause of the defect? How to solve these defects?   1.  Wire drawing  / trailing R eason:   Wire drawing /tailing is a common defect in dispensing.   The common reasons for it are that the inner diameter of the glue nozzle is too small, the dispensing pressure is too high, the distance between the glue nozzle and the PCB is too large, the patch glue is expired or the quality is not good, the viscosity of the patch glue is too high, and it cannot return to room temperature after being taken out of the refrigerator, too much glue dispensed, etc.   Solution: For the above reasons : 1)  R eplace the nozzle with a larger inner diameter ; 2)  Reduce dispensing pressure; 3)  Adjust the "stop" height; 4)  Change the glue and choose the glue type wit...

  What is  Artificial Intelligence   PCB:  Artificial Intelligence PCB is a printed circuit board that uses artificial intelligence technology. Traditional PCBs are mainly used for the transmission of electronic signals and power, while AI PCBs integrate AI chips, sensors, algorithms, and software on printed circuit boards, giving devices the ability to become intelligent.   Application  F ields of  A rtificial  I ntelligence PCB:  1)  Smartphones and   C onsumer  E lectronics In the field of smartphones, artificial intelligence PCB can effectively improve the speed and accuracy of the device's recognition of user voice and fingerprints.  For example, Huawei's Mate and P series  smart phones   have built-in voice assistants th at use AI chips (such as the NPU in the Kirin processor) to improve the efficiency and accuracy of voice recognition . Huawei ’ s  biometric technology also uses AI chips to improve sp...

Application of PCB in Automotive Sensors

        With the rapid development of automotive electronic technology, PCB not only plays a key role in improving the performance and reliability of sensors, but also makes significant contributions in reducing size and cost. PCB is widely used in automotive sensors, mainly in the following aspects:   1. Electronic Control Unit (ECU) Integration Automotive sensor are often tightly integrated with electronic control units(ECU), where PCB play a key role. Automotive sensor PCB are capable of processing, transmitting and controlling sensor signals. With the help of PCB, sensors can monitor various vehicle parameters in real time and transmit data to ECU for analysis and response, just like a assistant of the car.     2.  Sensor Signal Processing Most of the data captured from sensors are analog signals and need to be processed such as amplification, filtering and conversion before they can be used. At this point, the integrated circuits and componen...
