Discussion on PCB semi-plug hole method
In production, sometimes encounter some customers, require part of the hole plug hole, but can not be fully plugged, the back of the plug hole solder window, and depth requirements, commonly known as "PCB half plug hole".
EMI avoidance techniques for PCB multi-layer board design
the idea that thin films can be used to give mechanical strength or adequate insulation to individual parts inserted into printed circuit boards is wrong. The components must be mechanically inserted and must have their own suitable caulking agent, so tha
The integration trend of semiconductor packaging and surface mount technology is obvious.
Technology refers to a technology in which chip components are mounted and welded on the surface of the printed circuit board. Compared with the traditional through hole assembly technology, the technology has the advantages of high assembly density, smal
Chemical deburring process of PCB circuit board
The process does not require specialized technical personnel to operate, operators only need to go through simple training, and in the operation, only need to pay attention to the general chemical reagent operation safety can be. In terms of environmental
Light-emitting diodes and their basic circuits
Light-emitting diodes and their basic circuits(1) Basic knowledge of semiconductors1. A semiconductor is a substance whose conductivity is between that of a conductor and an insulator. Its conductivity is related to temperature,light or doping concentrati
Chemically etched SMT patch processing template
On pre-tinned PCB, the porosity of BGA joint increases with the increase of solvent volatility, metal composition and melting temperature, and also with the decrease of powder size.
Device Basics Light Emitting Diodes
Device Basics Light Emitting Diodes Light Emitting Diode (Light Emitting Diode): It is a semiconductor component that emits light and has the electronic characteristics of a diode; therefore, anLED is first a diode (structure), and secondly it emits
Chemical deburring process of the latest PCB circuit board
In addition, the process can prevent hydrogen embrittlement, because the process does not form a closed space, which helps to prevent acidic materials during plating from being trapped inside the workpiece, thus preventing hydrogen elements from entering
Discussion on EMI Rules of high speed PCB Design
High-speed signal networks, such as clock signals, produce closed-loop results when multi-layer PCB lines are routed. Such closed-loop results will generate ring antennas and increase EMI radiation intensity.
EMI design specification steps for PCB circuit boards
Experienced power developers know that EMI suppression in the PCB design process can save a lot of time for EMI suppression design in the final process to the greatest extent. This article will explain to you the specification steps in PCB EMI design, int
The effect of PCB layer-stack design on EMI suppression is analyzed
In the case of the IC on our circuit board, the power layer around the IC can be regarded as a good high-frequency capacitor, which can collect the energy leaked by discrete capacitors that provide high frequency energy for clean output.
