One or more words contained in EM are emphasized in the sentence. If you move the EM element, that is, the emphasis on the content changes, the corresponding sentence also has a change in meaning.Seven, a

CSS reset refers to the style of resetting the browser. In various browsers, the CSS selector will default some values, such as when the H1 is not set to a value, display a certain size.But not all browsers use the same values, so CSS Reset is used to make the style of the Web page consistent across browsers.Here are a few of the main CSS reset codes:1.

AJAX, an acronym for Asynchronous JavaScript and XML, is a popular technology in today's fast-growing web development community. While this new technology provides great power, it also burns an indisputable argument over the "Back" button issue. The author of this article will explain how to use Ajax in the real world and how to evaluate its value in a project.

Original article address: PCB decoupling capacitor reasonable configuration Author: ker11f
I. Category of decoupling capacitors in PCB
The decoupling capacitor can be used for energy storage when the operating voltage of the integrated chip or circuit board is compensated. It can be divided into three types: integral, partial, and inter-board.
The overall decoupling capacitor is also called a bypass capacitor. It operates in a low frequency (
Local decoupling capacitors have two functions. First
to claiming that its tape library can be managed in the SMI-S-compliant console, it also provides APIs (application interfaces ), other vendors can use these APIs to manage the ADIC tape library. Currently, EMC uses this method: In the same EMC San topology, the ADIC tape library is displayed in real time together with other San components, however, the specific management work is still implemented through
1 : no function is provided in the circuit. It is only for convenience of debugging or Compatibility Design on the PCB. 2 : Jumper can be used. If a line is not used, do not paste the resistor directly (without affecting the appearance) 3 : when the matching circuit parameters are uncertain, use 0 ohm instead. during actual debugging, determine the parameters, then, it is replaced by a component of a specific value. 4. when you want to test the current consumption of some circuits, you ca

6. Act as an inductor or capacitor under a high-frequency signal. Inductance is used to solve EMC problems. Such as location, power supply, and IC pin.
7. Single Point Grounding (Protection grounding, working grounding, DC grounding are separated from each other on the equipment, and each of them becomes an independent system .)
8. Use fuses. Because the circuit breaking current on the PCB is large, if sho

With the popularization of 3G technology and the development of wireless standards and technologies such as LTE, NFC, Bluetooth 4.0, cmms B, and MIMO, mobile Terminals need to integrate multi-band main antennas (supporting 2g, 3G, LTE and other multi-standard), as well as GPS, BT, WiFi, NFC, wireless charging and other antennas.
As a result, terminal antenna engineers are facing huge challenges:
Antenna size

Before designing a multilayer PCB, the designer must first determine the structure of the PCB based on the circuit size, circuit board size, and EMC requirements, that is, it is decided to adopt a 4-layer, 6-layer, or more layers of the circuit board. After determining the number of layers, determine the placement location of the inner electrical layer and how different signals are distributed on these layers. This is the choice of multilayer PCB stac
", which forms multiple links, if a disk is selected from the storage on the host, many disks may be released on the host, which will make the operator unable to choose which disk to operate. To avoid this cumbersome disk link, the multi-path software is used to aggregate multiple paths. It facilitates disk management and load balancing. If one link is disconnected, other links are still available, which will not affect disk access.
Several multi-path software:
