I've done whatever I want

Chapter 282 No Plan to Change Jobs

Since Jiang Hua went to Suzhou factory as director in 2006, Logitech has not seen him for almost three years. When they were in Shanghai, they were drinking buddies and often ate Journey to the West chicken and chicken at Dawu Times Hotel. Steel duck, after receiving a call from Jiang Hua inviting him to drink, he agreed without hesitation.

"Brother Luo, it's been a long time since we got together!" Han Leng sighed with emotion in the tavern by Jinji Lake.

"Old Han, you left Ming Yueguang in 2003 without even saying hello, abandoned our group of brothers and went to make a fortune outside. You will punish yourself with three drinks!" Logitech said with a smile.

"I'm sorry, I just changed my job to be the vice president at that time. Everyone knows about it. I'm afraid it will have a bad impact!"

"Six years have passed. You have changed a lot. You and Jiang Hua started a business together and became the boss. Congratulations!" Logitech said.

"Jiang Hua and I are tired of the working life. It is impossible to work in this life. We have no choice but to start a business to make a living!" Han Leng laughed.

"Come! We haven't seen each other for a long time. Let's talk slowly if we have anything to say. Let's have a drink first to moisten our throats!" Jiang Hua said, shaking his lush hair.

"cheers!"

"Dry!"

The three of them raised their glasses and stood up. They all raised their heads and drank the whole drink in one gulp.

"Mr. Luo, I heard that you also left Ming Yueguang and are now starting a business with Xin Tong?" Han Leng put down his wine glass and asked.

"Xin Tong is the boss, I work for him!"

"Xin Tong is now prosperous and has won Suzhou Wuji Semiconductor!" Han Leng said with emotion.

"Boss Xin also has two companies, one in Shanghai and one in Shenzhen. His net worth has already exceeded [-] million!" Logitech said.

Worth over [-] million?

Han Leng and Jiang Hua were both shocked.

Some time ago, Jiang Hua was comforting himself with the villa in Jinji Lake and earning millions a year. Now it seems that it will take until the Year of the Ox and the Moon of the Horse to catch up with Xin Tong!

In short, I have been crushed in all aspects of my life, and there is absolutely no hope!
"Xin Tong is the pride of Mingyueguang FOL Engineering Department. He was recently admitted to Tsinghua University as a graduate student." Logitech said proudly.

Xin Tong really went to Tsinghua University!
Han Leng didn't even believe it when Jiang Hua mentioned it before, but now he has no choice but to believe it: "That's awesome!"

"I grew up under the same roof. How come they are so good? I feel so ashamed!" After listening to Logi's words, Jiang Hua lowered his head and sighed, then shook his head.

"How is Wuji Semiconductor's business now?" Han Leng asked after a pause.

"Old Han, our company's orders have been queued up to the end of the year. We are currently studying the copper wire process with our customers. If this process can break through by the end of this year, Wuji Semiconductor will have a good year with explosive performance next year." Logitech He picked up a piece of chicken and said while eating.

"Damn! Have you developed copper wire technology?" Jiang Hua's eyes widened.

Originally, he thought that Wuji Semiconductor would become a competitor of Ruoshui Semiconductor, but he did not expect that they were developing a new process. Once Wuji Semiconductor successfully mastered the copper wire process, it would leave Ruoshui Semiconductor far behind.

"Yes, now the market is beginning to pay attention to copper wire technology!" Logitech said proudly.

"Lao Luo, I heard that the advantages of copper wire technology are obvious, but process development is very difficult, right?" Han Leng asked.

Since taking over Ruoshui Semiconductor, many customers have mentioned copper wire technology to him, but he has rejected them all. He has been reluctant to receive orders for gold wire technology. Where can he have time to pay attention to copper wire technology?

Besides, he's an idiot when it comes to copper wire craftsmanship!
But when he heard Logitech say that Wuji Semiconductor was developing copper wire technology, he felt a chill down his back.

"Old Han is right. Traditional semiconductor packaging uses gold wires, which are expensive and the reliability of the chips is average. People have been looking for metal materials that can replace gold wires. At present, aluminum wires and copper wires are more ideal." Logi took a sip of wine and said. "So that's it!" Han Leng nodded.

"The material cost of packaging is mainly welding wire. For the same specifications of welding wire, the price of copper wire is 1/10 of that of gold wire." Logitech talks about packaging technology in detail.

"The cost advantage is very obvious!" Han Leng sighed.

"In addition to cost considerations, the chip reliability of the copper wire process is also better than that of gold wire!" Logitech continued.

"Really?" Han Leng was full of curiosity.

"From the perspective of electrical performance, the conductivity of copper wire is about 1.33 times that of gold wire. Copper wire can carry a larger current and is more advantageous for use in smaller diameter leads for high-density integrated circuit packaging." Professional When people talk about professional topics, Logitech simply can’t stop the car.

"too professional!"

"From the perspective of thermal properties, copper wire has a higher thermal conductivity than gold, aluminum and other materials, and in terms of thermal expansion properties, copper has a lower thermal expansion coefficient, which can have better heat dissipation performance and thermal stability in high-density semiconductor devices. performance."

"awesome!"

“In terms of mechanical properties, copper has higher hardness, and bonded copper wires are better than gold wires in terms of elongation and breaking force. Not only are they more resistant to mechanical stress, they can also avoid collapse problems, improve arcing properties and It has more advantages in terms of consistency and can effectively improve the performance reliability of the packaged semiconductors."

"Lao Luo, you are indeed a technical person and know a lot of things." Han Leng gave a thumbs up.

"Boss Han, I suggest that Ruoshui Semiconductor research this copper wire process as soon as possible, otherwise it will be ruthlessly eliminated by the market!" Logitech said.

"Brother Jiang, what Mr. Luo said makes sense. No wonder many companies have approached us to develop copper wire technology. They didn't expect that the advantages of copper wire technology are so obvious. We still need to start research on copper wire technology as soon as possible!" Han Leng turned to Jiang Hua said.

"Old Han, there are currently very few engineers and technicians who can master copper wire technology. As far as I know, developing copper wire technology is not easy!" Jiang Hua said.

"Boss Jiang is right. The hardness of copper wire makes it difficult to control the ultrasonic energy or bonding force. Excessive bonding pressure will cause the aluminum layer of the pad to be extruded. If there is a short circuit between the extruded aluminum and the surrounding aluminum strips, there will be It makes the chip function ineffective. In addition, during the copper wire bonding process, the phenomenon of pad cracking is also a relatively common phenomenon. Copper wire process development is not that easy." Logitech said.

"Lao Luo, you are now a rare talent in the semiconductor packaging and testing industry. Those who master Logitech will conquer the world!" After Han Leng finished speaking, he winked at Jiang Hua.

"Thank you, thank you. I also crossed the river by feeling the stones!" Logitech smiled.

"Lao Luo, I have discussed with Boss Han and would like to invite you to join our Ruoshui Semiconductor!" Jiang Hua said after seeing Han Lengzhi's eyes.

Logi was stunned when he heard this.

In terms of relationship, these two people have known each other for a long time, and they were brothers in the bright moonlight. However, Luo Ji did not dare to compliment them as people.

"My job is stable now and I have no plans to change jobs!" Logitech said.

"How much does Xin Tong offer you? We can treat you with double the salary!" Han Leng said, taking a sip of wine.

"Old Han, this is not about money! I have no plans to change jobs for the time being!"

"Lao Luo, we can also talk about shares. As long as you are willing to join our Ruoshui Semiconductor, everything can be discussed!" Han Leng said.

Seeing what Han Leng said, Logitech couldn't refuse him face to face, so he smiled and said: "You two are my brothers from Logitech. Thank you very much for your invitation. Changing jobs is not a small matter. Please let me go back and think about it carefully!" "

"Lao Luo, Lao Han and I are waiting for you at Ruoshui Semiconductor. Come on, cheers!" Jiang Hua raised his glass.

"cheers!"
