    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 ...

    Author: Judy Chen | Catgorys: PCB Assembly Industry

     

    The printed circuit board (PCB) communicates with the SMT production line and contains all relevant manufacturing data. This is achieved through the HARTING RFID-4-SMT automatic identification solution. The solution reduces error rates and radically simplifies documentation requirements to form a single-volume automated printed circuit board (PC...
     
     

    RF circuit layout

    Author: Judy Chen | Catgorys: PCB Layout&Design

     

    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...
     
     

    How to Solder the Chip Components

    Author: stan stan | Catgorys: PCB Assembly Industry

     

    How to solder the chip components,There are two types of soldering methods for chip components:One is manual soldering by soldering the pad with an electric soldering iron, then clamping the end of the chip component with a tweezers, and fixing the other end of the component to the corresponding pad of the device with a soldering iron. After the...

    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...
