Click the blue text to follow us In the PCBA manufacturing process, people often ask: “Should we use SMT technology or DIP technology?” In fact, neither is absolutely better; they just have different application scenarios and process requirements. For many customers with electronic product outsourcing needs, understanding the differences and selection logic between SMT and … Read more
The bipolar junction transistor, also known as a transistor or BJT, is a core component in analog circuits. It can be classified into NPN and PNP types based on structure; silicon and germanium types based on material; low-frequency, high-frequency, and ultra-high-frequency types based on operating frequency; and small, medium, and large power types based on … Read more

In the 1930s, radio technology was introduced to China, but radios became luxury items due to their high prices, making them rarely purchased by individuals. Before 1958, there were no radio manufacturing plants in Shandong Province, a situation that changed in 1959. The Shandong Shengjian 83 Factory, located in Wangcun Town, Zhoucun District, formed a … Read more
Who has the best hands-on skills? On Twitter, I saw a 19-year-old blogger who spent a full 3 years to manually create a CPU with 1200 transistors. This American college student named Sam Zeloof ultimately built a CPU with 1200 transistors! It was achieved using a 10-micron polysilicon gate technology and named Z2. The key … Read more
Today, LED lights have become the mainstream for lighting, with very few households using incandescent bulbs. The main advantage is that LED lights are more energy-efficient, consuming over 70% less power than incandescent bulbs for the same light output.LED lights have a longer lifespan compared to incandescent bulbs. Anyone who has used incandescent bulbs knows … Read more
