    How to Design the 4 Layer PCB Stack Up

    Author: Judy Chen | Catgorys: PCB Layout&Design

     

    How to Design the 4 Layer PCB Stack Up How to design the stack up when designing a 4 layer PCB board?   In theory, there are three options.   Programme I: One power supply layer, one ground layer and two signal layers, those are arranged as below: TOP (signal layer); L2 (ground layer); L3 (power layer); BOT (signal layer).   Progr...
     
     

    PCB Impedance Control

    Author: admin | Catgorys: PCB Layout&Design

     

    PCB Impedance Control is the characteristic impedance of a transmission line formed by PCB conductors. It is relevant when high-frequency signals propagate on the PCB transmission lines. PCB Impedance Control is important for signal integrity: it is the propagation of signals without distortion.     The impedance of circuits board is ...

    PCB Stack Up   Before wiring, we have to make sure the circuit board is stacked, just like building a house with walls. The determination of circuit board stack structure is related to the complexity of circuit design and the consideration of electromagnetic compatibility. The following diagram shows the common stacking methods of four-laye...

    Author: Judy Chen | Catgorys: PCB Layout&Design

     

    Board design is a critical and time-consuming task, and any problem requires engineers to examine the entire design on a network-by-component basis. It can be said that the design requirements of the board are as good as the chip design. A typical board design flow consists of the following steps:     The first three steps take the mo...

      Does the Impedance Control line Increase the Cost of the PCB Board? Yes, it will increase the manufacturing cost for your PCB design. However, there are 3 major elements that you can control the PCB manufacturing cost:   1. Configuration   First, consider the PCB size. When the PCB size is too large, the printed lines are long,...

    7 steps to design a perfect PCB

    Author: admin | Catgorys: PCB Layout&Design

     

    PCB was born in 1936. The United States used this technology extensively in military radios in 1943; since the mid-1950s, PCB technology has been widely adopted. At present, PCB has become the "mother of electronic products", and its application has almost penetrated into various terminal fields of the electronics industry, including computers, ...
     
     

    RF PCB design layout and recommendations

    Author: admin | Catgorys: PCB Layout&Design

     

    1.RF transmission line   Many Maxim RF components require an controlled impedance transmission line that transmits RF power to (or transmits power from) IC pins on the PCB. These transmission lines can be implemented in the outer layer (top or bottom layer) or buried in the inner layer. Guidance on these transmission lines includes discussi...
