What are the Advantages of PCB Wave Soldering

图片
      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 t...

Problems that Need Attention in PCB Wave Soldering Technology

图片
Wave soldering is a soldering  technology   used for PCB mass manufacturing, mainly used for soldering through-hole components. The solder is usually a mixture of metals.   So what problems should be paid attention to in the  PCB wave soldering   technology?       1.  Before wave soldering, please check the operation of the equipment, the quality of the PCB to be soldered and the condition of the plug-in.     2. If there is green oil in t he component hole, it will lead poor tin plating in the hole. So, please note that the green oil in the hole does not exceed 10% of the hole wall.     3. If the thickness of the coating on the hole wall of the component is not enough, it will also cause poor tin plating in the hole, so the thickness of the hole wall should be greater than 18 μ m.       4. Please note that the hole wall not to be too rough, otherwise it may cause false welding or poor welding in the hole. ...
