esd prevention

Static electricity is a kind of natural phenomenon that people are very familiar with. Many of the functions of electrostatic have been applied to military or civilian products, such as electrostatic precipitator, electrostatic spraying, electrostatic separation, electrostatic copying and so on. However, electrostatic discharge ESD (electro-static discharge) has become a hazard to electronic products and equipment, resulting in the malfunction of elec

The ISO image file was used to install the system, but during the Windows 10 upgrade, it is not always necessary to provide an ISO image download, only an ESD image file is left in the temporary directory of the hard disk. An ESD file can be used to implement a rollback of the system version, but it is not directly intended to install the system. It is imperative that you fully understand the

Installation of the original system is very easy to encounter some trouble problems, such as WIN8 flagship system installation of ESD format file prompts "Windows source is invalid", the ESD file format compression rate is high, small size, we download the WIN8 system is such a format, So WIN8 system installation of ESD format file often prompts "Windows source i

In the ESD format, Microsoft began using a new system image file compression format in Windows8, a higher compression rate than WIM, but currently only DISM supports the processing of ESD files. In addition, most of the ESD files are encrypted and DISM cannot be processed directly. So the best way to do this is to decrypt the

Bav99/ESD Interference or discharge damage circuit/interface Protection Circuit Bav99 is designed for the purpose of ESD. It is afraid that the signal line is vulnerable to ESD Interference or discharge damage the circuit. Because these interfaces are interconnected with each other, it is afraid that the received signal has large static electricity. When several

A while ago a friend said they had a project in which there was a process circuit for ESD protection. I couldn't understand it at the time. But then the more I see the more I understand. Now share with you. is also a contribution to high-tech. The right of the regulator diode plays the role of the control voltage, when the regulator diode conduction, will be in its high over a current, the current through the resistance below, will cause the voltage o

ESD is the release of static electricity, which can cause various damage to precision semiconductor chips, such as penetrating the thin insulating layer inside the component, and damaging MOSFET and the gate of CMOS element; The trigger is locked in the CMOS device, causing a short circuit of the PN junction of the reverse offset and forward offset, and melting the welding wire or the aluminum wire inside the active device. In the computer industry,

EMC testing consists of 4 main items:1. ESDUsing electrostatic gun test, contact voltage ±6kv, the whole box and the internal visible metal parts are detected;Air discharge positive and negative 8KV, detection of the box and the internal metal parts (such as Board jam body), the special detection of 220V power Plug and switch place.Note: The contact discharge and air discharge test is different from the electrostatic gun tip, contact discharge tip for sharp metal.2.

free of charge and you can easily download them from your website.We do not recommend that you manually clear the rogue software here, because the rogue software is becoming more and more complex, and it is no longer the kind of solution to simply delete a few files. Many rogue software can be solved before they enter the system, the system is modified and associated. When a user deletes a rogue software file without authorization, the system cannot return to the initial state, which causes the

In the past, I always caught a cold once a month. It seems that I have never caught a cold during this time, and my health is amazing. Summary: mainly prevention, combined with prevention Specific measures: 1. Every morning, an apple is definitely a good thing. It can not only defend against all kinds of diseases, but also supplement energy and improve work focus; 2. I have regular medication at home. F

Talk about Adsenser from Google AdSense large area blocked cheating Google AdSense site said, but to say the ban still have to start from cheating; this has a very embarrassing background, good faith for most people, especially personal webmaster is a high demand. Gentleman Love Money, take the Youdao, our problem in the understanding of the Tao, many people think that the income is more "way", and in Google's Dictionary, comply with the rules is the way, so there will be from the beginning of 2

First, manageability. An ideal intrusion prevention solution enables security settings and policies to be leveraged by a variety of applications, user groups, and agents, reducing the cost of installing and maintaining large security products. McAfee Intrushield is highly automated, manageable, and flexible enough to implement the installation in phases to avoid the inevitable false positives of the original intrusion detection system, enabling custo

In the previous blog (http://cloudapps.blog.51cto.com/3136598/1708539), we described how to use Apache's module Mod_evasive to set up anti-DDoS attacks, in which The main prevention is the HTTP volume attack, but the DDOS attack way, a lot of tools, a random search to know, we look back, what is called Dos/ddos, see Wikipedia:"Denial of Service Attacks (denial of servicesAttack, abbreviation:DoS), also known as flood attacks , is a network attack tech

According to statistics, in all hacker attacks, SYN attacks are the most common and most easily exploited one of the attack methods. I believe many people still remember the 2000 Yahoo site attack case, the hacker was using a simple and effective SYN attack, some network worm with SYN attack caused greater damage. This paper introduces the basic principle, tools and detection methods of SYN attack, and probes into the technology of SYN attack prevention
