    PCB Ground Wire Interference and Suppression

    Author: Judy Chen | Catgorys: Schematic Diagram

     

    In PCB design, especially in high-frequency circuits, some irregularities and abnormalities caused by ground interference are often encountered. This paper analyzes the causes of interference caused by grounding, and introduces three types of interference caused by grounding, and proposes solutions according to the experience in practical applic...

    Author: stan stan | Catgorys: PCB Layout&Design

     

    With the continuous development of the entire electronics industry, many products in the electronics industry have already established sophisticated upstream and downstream supporting enterprises. From a mature product design, design, manufacturing, assembly testing, packaging, wholesaler channels, etc., such an industrial chain is naturally gen...
     
     

    SMT Stencil

    Author: Judy Chen | Catgorys: Electronic Industry News

     

    SMT Stencil SMT surface mount, smt steel mesh is the key to accurate repeat printing of solder paste. Because the solder paste is printed through a steel mesh. The printed solder paste fixes the parts, and the parts are fixed to the substrate during reflow soldering. The stencil design contains the elements—the thickness of the steel mesh, the s...

    Circuit Board Conformal Coating Using

    Author: stan stan | Catgorys: PCB Assembly Industry

     

    After these decades, I believe that for everyone, especially the electronics company, the circuit board conformal coating is no longer strange, it is not a fast-moving consumer goods, but it is widely used in various electronic products in our lives, but There are Conformal Coating on the circuit board. I have to say that there are still many de...
     
     

    Uniquel Method Of DIY High Frequency Circuit Board

    Author: Judy Chen | Catgorys: PCB Manufacturing Technology

     

      Don't get me wrong - I really like printed circuit boards (PCB). Printed circuit boards are definitely essential for mass-produced products. Even amateurs can make almost perfect, repeatable circuits with a little practice. Moreover, printed circuit boards with good ground planes are important for high frequency circuits operating at fre...
     
     

    On the Technology of Rigid-flex PCBs

    Author: Judy Chen | Catgorys: PCB Manufacturing Technology

     

    There are many benefits of Rigid-flex PCBs panels that many designers didn't know before because they didn't have to use the technology. Now, however, more and more designers will face the pressure to build more and more dense electronic devices, and even more so, they will have to reduce the cost of manufacturing and reduce manufacturing time....
