Top 10 Global Semiconductor Manufacturers in 2020

-
Image
Market research firm Gartner recently released its 2020 revenue forecast for the semiconductor industry. According to Gartner's forecast, the revenue scale of global semiconductor manufacturers in 2020 will reach the US $449.838 billion, a year-on-year growth of 7.3%. "At the beginning of 2020, the Coronavirus (Covid-19) pneumonia outbreak was thought to hurt all end device markets, but the actual impact was minimal," said Andrew Norwood, research vice president at Gartner. Certain segments of the auto, industrial and consumer markets have been hit by a drop in business and consumer spending. However, the market benefits from home isolation, which dramatically increases the time spent at home and online." "Server demand is strong as super-scale customers (accounting for more than 65% of server demand in 2020) rush to add capacity to cope with additional demand during the lock-in period in the first half of 2020. Besides, strong corporate and consumer demand for ...

Which is better, reed relay or solid-state relay? how to choose?

-

Reed relay , also called reed switch and reed switch, is composed of a pair of elastic reeds made of magnetic materials. The reeds are sealed in a glass tube filled with inert gas. The reeds overlap and there is a gap between them. The working principle of the reed relay When there is no magnetic field, the two reeds in the glass tube filled with inert gas are separated, otherwise, under the action of the magnetic field lines, the two reeds in the glass tube are magnetized to attract and contact each other, so that the two pins are connected to the circuit. When the external magnetic force is removed, the two reeds in the glass tube are separated again, and the connected circuit is disconnected. The characteristics of the reed relay High reliability; high safety; high adaptability; long life; compact structure; small size; superior electrical performance; high-speed operation; wide application. The solid-state relay has a non-contact switch with an isolation function. There is no mecha...

The capacitor is commonly used in our daily life such as display capacitor, AC capacitor in air conditioners , parallel plate capacitor in electronic circuits. But in this article,     we will introduce the characteristics of a broken display capacitor？ The display is an input and output device of the computer. I believe that those who are familiar with the computer are not unfamiliar with the display capacitance. Capacitance refers to the ability to hold charges. There are many complex parts in the display, including capacitors. Then the display capacitance is broken. What characteristics? Let's take a look together below. Generally, capacitors are in the power supply part, and there are the following possibilities: • Can't click • Severe water ripples We can view the screen from the top or side of the screen when the display is black, and see if there is any displayed content. If there is any displayed content, it is a problem with the high-voltage board or the power ...
