In the earliest ABC-1 and ABC-2 computers, the memory chips were soldered directly to the motherboard. It wasn't until later that memory evolved into a separate part of the computer host, in the form of a memory module.

Compared with the original memory chip, the memory module has many advantages, such as the first memory module is usually a group of chips (8 or even 16), so it can provide a much higher addressing space for the computer than a single memory chip.

At the same time, the memory modules can be easily plugged and unplugged in the memory slots on the motherboard through a special interface design. Unlike the earlier memory chips, once they are soldered to the motherboard, they basically cannot be upgraded and replaced.

There are three main steps to assemble memory chips, that is, memory chips that have been packaged, into memory modules. The first is to design and produce a specialized PCB (printed circuit board), and it is through the printed circuit board that all the memory chips on the memory module are connected to the computer motherboard.

After the dedicated memory PCB is manufactured, the second step is screen printing. The so-called screen printing is to attach solder paste to certain specified positions on the printed circuit board through a hollow mold. And these are the places where the solder paste is glued to the next place where the memory chips need to be soldered.

So the last step is to accurately grab the memory chips to the position where the solder paste is attached, and then heat them in an oven, when the solder paste melts and then cools down, all the memory chips are firmly connected to the PCB, forming a complete memory module.

Although the production process of memory modules is much simpler than that of previous memory chips. But how to make the circuit performance on the PCB optimal. In fact, it is a great test of the technical skills of R&D personnel. After the PCB is produced, how to accurately bond the chip to the PCB is another production problem!

When Liu Chuanzhi communicated with Liu Wei. The idea of making my own memory also flashed in my head. Because compared to the more tightly controlled processors, Batumi has a much more lenient review of memory. Lianxiang can import memory chips from foreign semiconductor companies and then produce memory modules by itself.

But Liu Chuanzhi is not hot-headed, he knows very well the truth that greed is too much to chew! Technology research and development has always been a very risky thing, because your large investment does not necessarily get a corresponding return.

Lian Xiang had good luck before and successfully developed a cost-effective motherboard, so that he could take the lead in the market competition with his domestic counterparts.

But in order to develop their own motherboards. Liu Chuanzhi had invested almost all the profits accumulated by Lianxiang Company in the past two or three years. If the performance of the motherboard is not satisfactory, then even the entire development plan of the company will be dealt a major blow.

And don't look at the production technology of memory modules. Far lower than making memory chips. However, the current background of the company is still a difficult and high-risk research and development. The most important thing for Lianxiang to do now is to quickly expand the market by relying on the cost advantage that can be brought by self-produced motherboards.

Meanwhile. The motherboard developed by Lianxiang Company is only the first generation of products. There is room for continued improvement. So instead of taking the risk of developing another completely new R&D project, it is obviously much safer to invest limited funds in the technical improvement of the existing motherboard!

Although Liu Chuanzhi has no plans to let Lian Xiang produce his own memory for the time being, he is very interested in visiting the memory production factory. Since Liu Chang came to the door by himself, Liu Chuanzhi simply proposed that he wanted to go to the other party's factory for a field visit.

The production process of memory is not something that needs to be kept secret, so Liu Chang readily agreed to the other party's request, and personally drove to the hotel where Liu Chuanzhi stayed to pick up people the next morning.

"The line is highly automated. The cost should be a lot of money, right?" Liu Chuanzhi pointed to a set of large-scale automation equipment in front of him and said with some emotion.

The machine not far from him is called a grabbing machine. The chip can be automatically picked up from the feed without any human manipulation and placed precisely on the PCB where the solder paste is placed, and the whole process takes only a few seconds.

"Yes, this set of equipment imported from the United States cost nearly $3.5 million, and in order to raise funds, we had to conduct a third round of financing!" Liu Chang nodded and said.

Feiyue Company does not have its own PCB factory, and the PCBs required for the production of memory by the company are OEM produced by upstream manufacturers according to the design provided by Feiyue Company.

However, the total number of front-line workers in the entire Feiyue Technology Company still exceeds 100. After the chip is soldered and mounted, the PCB becomes a real memory module. However, if these products want to be marketed, they must be strictly tested at the factory. For example, the staff sitting behind the X-ray machine needs to double-check every solder joint of each memory module, but make sure that every solder joint has been soldered.

"$3.5 million is not a small amount!" Liu Chuanzhi, accompanied by Liu Chang, was very interested in Feiyue's fundraising ability after visiting Feiyue's factory.

You must know that Feiyue Company has been established for less than a year, and its fixed assets have exceeded 10 million yuan. And even think that the company has been established for almost four years, and the total assets are estimated to be less than 10 million yuan!

There are certainly many reasons that will affect the future development of the company, but the most important of them is undoubtedly technology and funding. Especially for funds, if Liu Chuanzhi can have sufficient funds in his hands, he thinks that the company's development pace will be much faster than now!

In the future, the company will carry out large-scale market expansion, and it is also very hungry for funds. Lianxiang's market expansion is in the form of opening brand stores, and opening a store naturally requires a lot of costs. If Liu Chuanzhi learns some experience from Feiyue Company and quickly raises a large amount of money, he can open Lianxiang's specialty stores all over China's major cities in one go.

As long as you can convince others that your project can bring great returns, then naturally someone will take the initiative to send you money! If Mr. Liu is interested, I can provide you with some information in this regard!

In fact, the company I worked for before was Hong Kong Oriental Venture Capital, which is the largest venture capital fund in Hong Kong and even in Asia, and has successfully incubated more than a dozen listed companies!" Liu Chang said with a smile. (To be continued.) )
