  • Method to quickly detect PCB board failure

    Making a PCB board is not a simple process to finish the board, just drill a hole and punch in the components. The production of PCB board is not difficult, but the difficulty lies in troubleshooting after the production is completed. Whether it is a personal hobbyist or an industrial engineer, i...

  • Make the functions of each layer in the PCB circuit board

    In the current circuit board industry, many PCB circuit board manufacturers can make multilayer boards, but whether their multilayer boards are doing well, then it depends on the manufacturer’s understanding of multilayer boards. The PCB circuit board includes many types of working layers, such a...

  • Factors caused by pcb solder joints

    Solder joint tip pull-out point refers to the bump of the solder on the solder joints of the copper foil circuit terminal of the circuit board, which has obvious sharp points. This situation is called solder-point pull-out points. The impact of solder joints on the circuit board In addition to th...

  • PCB power cord routing rules

    1. Decoupling should be carried out between the power supply pin and the ground pin of the chip. The decoupling capacitor adopts 0.01uF chip capacitors, which should be installed close to the chip to minimize the loop area of ​​the decoupling capacitor. 2. Widen the width of the power line and gr...

  • PCB layout rules and layout skills.

    PCB layout rules. 1. Under normal circumstances, all components should be arranged on the same side of the circuit board. Only when the top-level components are too dense, can some devices with limited height and low heat generation, such as patch resistance, patch capacitance, patch IC, be place...

  • How to clean PCB circuit board

    Recently, I have been assembling a lot of USB circuit boards, which reminds me of the best way to clean them after assembly. The “dirty” flux is used in the assembly work, so in theory I don’t have to clean it up, but if I don’t, it will leave an ugly sticky mess. Unfortun...
