    How to make High Frequency Printed Circuit Board

    Author: Judy Chen | Catgorys: PCB Manufacturing Technology

     

    Fabrication principle of High Frequency Printed Circuit Board In high frequency PCB design, the power supply is designed as a layer, in most cases, it is much better than the bus design, so that the circuit can always follow the path with the least impedance. In addition, the power supply board has to provide a signal loop for all signals genera...
     
     

    The Advantages of Aluminum Substrate PCB

    Author: stan stan | Catgorys: PCB Manufacturing Technology

     

    The advantages of aluminum substrate PCB   a. The heat dissipation is obviously superior to the standard FR-4 structure.   b. The dielectric used is usually 5 to 10 times the thermal conductivity of conventional epoxy glass and 1/10 of its thickness.   c. The heat transfer index is more efficient than the traditional rigid PCB. &n...
     
     

    FPC Process

    Author: Judy Chen | Catgorys: PCB Manufacturing Technology

     

    What is FPC ? FPC, flexible printed circuit, which is a circuit board mainly composed of CU (Copperfoil), A(Adhesive) and PI (Kapton, Polyimide). It has many advantages such as space saving, weight reduction and high flexibility, which has a wide range of applications in production and life, and the market is still expanding.   FPC structu...
