Test technology Based on high speed PCB interconnect design

Posted on October 08, 2018 by G

PCB interconnect design techniques include testing, simulation, and various related standards, where testing is the method and means to verify the results of various simulation analyses. Excellent test methods and means are necessary to ensure the analysis of PCB interconnection design. For traditional signal waveform testing, the main focus should be on the length of the probe leads to avoid unnecessary noise introduced by Pigtail. This article focuses on new applications and development of interconnect testing techniques.

RF circuit PCB design - component layout

Posted on September 26, 2018 by G

Since SMT generally uses infrared furnace heat flow welding to achieve component soldering, the layout of the components affects the quality of the solder joints, which in turn affects the yield of the product. For the design of RF circuit PCB, electromagnetic compatibility requires that each circuit module does not generate electromagnetic radiation as much as possible, and has certain anti-electromagnetic interference capability. Therefore, the layout of components directly affects the interference and anti-interference ability of the circuit itself. This is also directly related to the performance of the designed circuit.

Terminal termination of high speed PCB

Posted on September 21, 2018 by G

In high-speed PCB digital circuit systems, impedance mismatch on the transmission line will cause signal reflection and signal distortion such as overshoot, undershoot and ringing, and when the delay TD of the transmission line is greater than 20% of the signal rise time RT, the reflection The impact can't be ignored, or it will bring signal integrity problems. The method of reducing the reflection is: matching the source impedance with the transmission line impedance according to the characteristic impedance of the transmission line at the driving end thereof, or matching the load impedance with the transmission line impedance at the receiving end, so that the source reflection coefficient or the load reflection coefficient is zero.

The current worldwide demand for environmental protection has made electronic products more demanding in the miniaturization of the Ministry of Energy. This has also spurred the advancement of high-speed and large-capacity electronic products for data and information processing. On the other hand, IT products that are personally demanded are also moving toward functional integration, high-performance (high-speed), and low-consumption power. In the signal transmission mode of electronic products, the parallel transmission mode develops toward a continuous mode. And the way in which optical transmissions have been added to electrical transmissions has begun to emerge. The high integration and high frequency development of electronic components has led to a continuous increase in the demand for high-frequency printed circuit boards.

(1) Cross circuit is not allowed in the printed circuit. For the lines that may cross, it can be solved by “drilling” or “winding”. That is, let a certain lead be "drilled" from the gap under other resistors, capacitors, and triodes, or "wrap" from one end of a lead that may cross. How to make the circuit complicated in special cases, to simplify the design It is allowed to bridge the wires to solve the cross circuit problem.

How to strengthen anti-interference ability in PCB design

Posted on September 10, 2018 by G

To get the best performance from an electronic circuit, the board is the support for the circuit components and devices in the electronics. Even if the schematic design of the circuit is correct and the printed circuit board is not properly designed, it will adversely affect the reliability of the electronic product. When designing a printed circuit board, it is important to use the correct method, follow the general principles of PCB design, and conform to the requirements of the anti-jamming design and the layout of the wires. In order to design a PCB of good quality and low cost, the following general principles should be followed:
