In Intel, Taiwan Semiconductor, Samsung previously strongly appealed to the US Congress to pass the chip Act, to provide $52 billion in funding subsidies, the news pointed out that the US Congress has decided to vote on the bill on Tuesday. Senate Majority Leader Chuck Schumer said the U.S. Congress could vote as soon as …
Chip testing is divided into two types, one is wafer testing, also known as CP testing, also known as intermediate testing. As mentioned before, after the wafer is manufactured, the electrical performance and circuit function of each chip on the wafer are tested to ensure that the wafer can realize the circuit function of the …
We know that power devices are the core of electric energy conversion and circuit control in electronic devices. They change the voltage, frequency, phase and DC/AC conversion functions in electronic devices by using the characteristics of unidirectional semiconductor conduction. Power devices are divided into many categories based on controllability and other usage factors. Common classifications …

We are all familiar with electronic products, but we may be a little strange about electronic chips, but electronic chips are everywhere in our life, but also indispensable. With the rapid development of electronic information science and technology, the functions of chips are becoming more and more powerful. Among them, electronic products account for the …
Electronic chips are now as important to electronic products as the human brain. At the same time, many people have more questions about chips, such as what is the manufacturing process of electronic chips? Today, xiaobian will share with you: There are four steps to make a chip, which are silicon purification, chip photolithography, chip …
The 12th WTO Ministerial Conference will be held in Geneva in mid-June. Recently, the Semiconductor Industry Association (SIA) weighed in on tariffs on electronic transmissions. That's when tariffs on electronic transmissions, the 25-year-old basis of global digital trade, will be settled within a week The SIA argues that the WTO has not imposed tariffs on …
Tariffs on electronic transmissions would hit the global semiconductor industry hard Read More »
Is it profitable to make chips? Of course it makes money! But if you want to make a lot of money in the chip field, it is not easy, because core is a high threshold, long cycle, big investment industry. Building a wafer factory is often billions of dollars, even tens of billions of dollars, …
Everyone is asking about SCM. Today, xiaobian will share four knowledge points about SCM with you: 1. Introduction to SCM: Take PC as an example, including CPU, memory, and hard disk. You can understand microcontroller is a super small PC, CPU, memory, hard disk are all in this chip (MCU). 2. The use of microcontroller: …

The L6565 is a current mode master controller IC designed specifically for building off-line quasi-resonant ZVS (zero voltage switching when switched on) flyback converters. The quasi resonance operation is realized by the transformer demagnetization induction input that triggers the MOSFET to turn on. The power capacity of the converter varies with the grid voltage and …
To ensure rated voltage over 600V, the L6574 is manufactured with BCD off-line technology, which makes it ideal for lamp ballast applications. The device is designed to drive two power MOSFets using a classic half-bridge topology that ensures all the functions required to drive and properly control fluorescent bulbs. The L6574 has a dedicated timing …
