    • July 05. 2021

    The key to PCB EMC design is to minimize the reflow area and let the reflow path flow in the direction of the design. The most common return current problems come from cracks in the reference plane, changing the reference plane layer, and the signal flowing through the connector. Jumper capacitors or decoupling capacitors may solve some problems, but the overall impedance of capacitors, vias, pads...

    Learn About Different Types of PCBs and Their Advantages

    A printed circuit board (PCB) is a thin board made from fiberglass, composite epoxy, or other laminate materials. PCBs are found in various electrical and electronic components such as beepers, radios, radars, computer systems, etc. Different types of PCBs are used based on the applications. What are the various types of PCBs? Read on to know. What are the Different Types of PCBs? PCB’s are often ...

  • Printed Circuit Boards Manufacturing
    • August 09. 2021

    If you are wondering what exactly Printed Circuit Boards (PCBs) are and how they are manufactured, then you are not alone. Many people have a vague understanding of "Circuit Boards", but really aren't experts when it comes to being able to explain what a Printed Circuit Board is. PCBs are usually used to support and electronically connect the connected electronic components to the board. Some exam...

Special plates (1) High tg pcb material With the development of the electronic information industry, the application fields of printed boards have become wider and wider, and the requirements for the performance of printed boards have become increasingly diversified. In addition to the performance o...

  • Comparative tracking index of PCB
    • August 19. 2021

    The tracking resistance of the copper clad laminate is usually expressed by the comparative tracking index (CTI). Among the many properties of copper clad laminates (copper clad laminates for short), tracking resistance, as an important safety and reliability index, has been increasingly valued by PCB circuit board designers and circuit board manufacturers. The CTI value is tested in accordance wi...

  • PCB Pad size
    • August 25. 2021

    When designing PCB pads in PCB board design, it is necessary to design strictly in accordance with relevant requirements and standards. Because in the SMT patch processing, the design of the PCB pad is very important. The design of the pad will directly affect the solderability, stability and heat transfer of the components. It is related to the quality of the patch processing. Then what is the PC...

  • Grid copper, solid copper. Which one?
    • August 27. 2021

    What is copper coating? The so-called copper pour is to use the unused space on the PCB as a reference surface and then fill it with solid copper. These copper areas are also called copper filling. The significance of copper coating is to reduce the impedance of the ground wire and improve the anti-interference ability; reduce the voltage drop and improve the efficiency of the power supply; if it ...

  • How to control circuit board warpage&twist
    • August 30. 2021

    Warping of the battery circuit board will cause inaccurate positioning of the components; when the board is bent in SMT, THT, the component pins will be irregular, which will bring a lot of difficulties to the assembly and installation work. IPC-6012, SMB-SMT Printed circuit boards have a maximum warpage or twist of 0.75%, and other boards generally do not exceed 1.5%; the allowable warpage (doubl...
