Chapter 88 85: Common sense?
after an hour.

Ma Changsheng and Chang Yongqing took the raw materials to the Dragonfly Film Factory, two kilometers away from the Deep Blue Film Factory, for OEM processing.

When the two arrived at the Dragonfly Film Factory, they were greeted by a fat, bald man with a big belly and a smiling face.

"Brother Ma." Xiong Dadong said with a smile.

"This is Chang Yongqing, the sales manager of our factory, and this is Xiong Dadong, the owner of Dragonfly Film Factory." Ma Changsheng patted Chang Yongqing on the shoulder and introduced.

"Mr. Chang is really young and promising." Xiong Dadong said with a cheerful smile.

"Boss Xiong, arrange for someone to unload the goods. We will conduct trial production today." Ma Changsheng said.

"No problem." Xiong Dadong said and walked towards the factory.

After a while, Xiong Dadong walked out of the warehouse with four young people and two trucks.

Although the four young men are not very tall, the tendons and flesh on their bodies are clearly visible, indicating that these people usually do heavy work.

Ma Changsheng opened the back door of the van, and several people loaded the raw materials onto the truck.

"Brother Ma, I have already vacated the No. [-] machine for you. Let's go in and adjust the machine first. They will close the door for you after unloading the goods." Xiong Dadong said.

"Okay, let's go in first." Ma Changsheng said after looking at a few people.

Then the three of them walked into the factory building of Dragonfly Film Factory. The factory building of Dragonfly Film Factory has only one floor and the entire factory building is built with steel structure.

However, the factory building of Dragonfly Film Factory is much larger than that of Deep Blue Film Factory. The factory building of Dragonfly Film Factory is more than 7000 square meters, and there are a total of [-] machines placed in the factory.

Under the leadership of Xiong Dadong, the two came to the No. [-] film blowing machine.

The film blowing machines of Dragonfly Film Factory are the same as those of Deep Blue Film Factory. They are all film blowing machines manufactured by Code Equipment. Ma Changsheng was very familiar with Code's operating system and came to the control panel to operate it directly.

Ma Changsheng skillfully operated the machine, set the temperature to 350 degrees, and set other processing parameters.

At this time, four young men came over pulling a cart.

"Let's put a bag of raw materials in for trial production first," Ma Changsheng said after completing the settings.

Two young men carried a bag of raw materials to the feed port. Then they opened the mouth of the woven bag and poured the raw materials into it.

"All the raw materials have been poured in." The young man pouring the raw materials shouted loudly.

When Ma Changsheng heard what the other party said, he pressed the start button on the panel.

After 10 minutes, a layer of film comes out of the film blowing port. A worker grabs the film and passes it through the machine, and sticks the film on the last roller.

The deposited film is continuously produced from the machine.

Tencent Binhai Building, No. 33 Haitian [-]nd Road, Nanshan District, Shenzhen.

At this time, there was still half an hour before getting off work, but Xiao Ma didn't want to wait until get off work before leaving. After all, the traffic jam capacity in Shenzhen City was still very scary.

Before leaving get off work, Brother Ma opens his e-mail to see if there is any missed work.

When he opened the mailbox, he saw the email sent to him by Zhang Dalong.

The title is [A very interesting competing product].

Zhang Dalong only introduced WeChat in a very brief way in the email, and he focused on the WeChat walkie-talkie function.

"It's really an interesting function." Xiao Ma said after lighting a cigarette.

In addition to explaining the functions of walkie-talkies, Zhang Dalong also analyzed the benefits that walkie-talkies can bring.

As for WeChat?

They don't take WeChat seriously at all. Enemies like WeChat are born every two days. Such enemies are not worthy of their concern at all.

What they have to do is copy each other's good stuff
cough cough.

They just need to incorporate each other's strengths into the Penguins.

In their view, enemies like WeChat will soon go bankrupt due to lack of funds.

Why is Brother Ma so sure?
Because they almost went bankrupt because of financial problems.

Now that Penguin has become the dominant player in the industry, no venture capital is willing to invest in instant messaging software, because venture capitalists know that going against Penguin is courting death, and the money invested will most likely be wasted.

As long as they are not stupid, no one is willing to do this kind of business.

After reading Zhang Dalong's email, Brother Xiao forwarded it to the person in charge of the technical department, asking the other party to add the intercom function to the next version of Penguin as soon as possible.

After Xiao Ma finished forwarding the email, he closed the computer and left his office.

December 2009, 5

Chang Yongqing drove the BYD van of the film factory to No. 1639 Yanlong Avenue, Pingdi Street, Longgang District.

Chang Yongqing drove the car to the parking lot and called Xu Donghang.

"beep beep beep"

"Who is it?" Xu Donghang asked after answering the phone.

"Hello, Director Xu, I am Chang Yongqing, the sales manager of Shenlan Film Factory. Our stacked film started production yesterday. We trial-produced a batch of stacked films yesterday. I sent over samples of stacked films.

I'm in the parking lot of your park now. Where should I send these films? "Chang Yongqing said.

"There is a sign in the parking lot. Follow the sign and go in the direction of Factory Building 2. You go to Factory Building 2 and wait for me. I will go there now." Xu Donghang said.

Chang Yongqing stuck his head out of the car and looked around before finally finding the sign.

"I found the sign. Let's drive there now." Chang Yongqing said after taking his head back.

"Okay, let's meet in Factory No. 2." Xu Donghang said.

After a while, Chang Yongqing followed the signs and came to the door of Factory No. 2.

Chang Yongqing parked the car at the door and got out of the car.

After waiting for 5 minutes, Xu Donghang slowly walked over from the aisle.

"Manager Chang?" Xu Donghang said with a slight smile.

"Hello, Director Xu." Chang Yongqing took out his business card from his pocket and handed it to the other person.

"How many samples did you send this time?" Xu Donghang asked after taking the business card and looking at it.

"This time we sent a sample of 85 meters, and we started mass production and supply. Our current production capacity is 150 meters per day. In two or three days, we will expand the production to [-] million meters per day. What do you think? After confirming that there are no problems with the samples, we can sign the contract and start supplying." Chang Yongqing said.

Ma Changsheng is already negotiating with another film factory about OEM. If nothing else, the negotiation should be completed within the next two days. The production capacity of the other film factory is about 70 meters.

"Manager Chang, wait for me here, I'll find a worker to come over and pull the goods." Xu Donghang said.

"Okay, Director Xu." Chang Yongqing nodded.

After a while, Xu Donghang returned to the door of the factory with two workers. Chang Yongqing immediately opened the trunk of the van. There were three large film rolls in the trunk.After Chang Yongqing finished delivering the goods to Shennan Circuit, he had to send the other two rolls of film to Pengding Holdings and Jingwang Electronics.

"This roll of film is from your factory, and the other two rolls are from other factories." Chang Yongqing said.

After hearing what Chang Yongqing said, the two workers quickly put a roll of film on the pallet truck.

"Mr. Xu, can you start trial production immediately? If you can start trial production immediately, I hope to go in and have a look. If we encounter any problems, we can communicate in time." Chang Yongqing looked at Xu Donghang said.

"There is no problem with small-scale trial production." Xu Donghang replied.

If there were any problems with the trial production process after Chang Yongqing left, he would have to contact Chang Yongqing to ask the other party to do it again. It would be best to conduct the trial production with the other party present.

Then Xu Donghang took Chang Yongqing into Factory Building No. 2.

PCB board is an indispensable part of electronic products. It is the carrier of electronic components and a bridge for circuit connections. The manufacturing process of PCB boards is a complex process that requires multiple steps to complete.

Step [-]: Design the circuit diagram

Before making a PCB board, you need to design a circuit diagram.The circuit diagram is the basis for PCB board production, which determines the layout and connection method of the PCB board.Designing circuit diagrams requires the use of circuit design software, such as Altium Designer, Eagle, etc.

This step is completed by the designers in the office.

Step [-]: Make the printed circuit board.

Printed circuit board is the basic material for PCB board production.Making a printed circuit board requires covering copper foil on a fiberglass substrate, and then removing the unnecessary copper foil through chemical etching or mechanical processing, leaving the required circuit lines.

This step will be completed in the factory, and each step is completed manually.

It’s not that this step can’t be completed fully automatically, it’s just that automation is not that advanced in this era.

Step [-]: Make PCB board.

Making a PCB board requires matching the printed circuit board with the circuit diagram, and then completing it through process steps such as photolithography, etching, drilling, and film pasting.

1. Photolithography: The circuit diagram is transferred to the printed circuit board through photolithography technology to form a photoresist layer covering the copper foil.

2. Etching: Soak the printed circuit board in chemical liquid to remove unnecessary copper foil, leaving the required circuit lines.

3. Drilling: Drill holes at the locations that need to be connected for subsequent welding.

4. Film: Cover the surface of the PCB board with a protective film to protect the circuit lines from damage.

The film to be attached here is a deposition film. In addition to protecting the circuit board, the deposition film also has the function of preventing leakage of the circuit board.

Before the accumulation film appears, special ink is used to protect the PCB version.

But PCB ink has a big problem, that is, it takes a long time to dry a PCB board. The accumulation film completely solves the drying problem.

The deposited film only needs to be heated and pressed on the PCB surface to complete the entire process.

The stacked film is many times better than PCB ink in terms of production time and cost, and the insulation capacity and heat resistance of the stacked film are five to six times that of PCB ink.

Xu Donghang and his party went directly to the equipment for the film application process.

At this time, a worker was laminating a PCB board. The worker also said hello after seeing Xu Donghang.

"Director Xu." Feng Chengxian greeted.

"Old Feng, there is a batch of new films here. You can use this film to make a batch of boards. Just make a hundred boards. This batch of boards does not need to be sent to customers. After they are made, they are sent to the laboratory for Lao Zhang. "Xu Donghang said.

"No problem." Feng Chengxian nodded.

Feng Chengxian worked very quickly. He immediately connected the film to the tool, cut out the pieces of film, and then stacked the PCB board and the stacked film layer by layer.

After stacking, Feng Chengxian put the PCB into the high-temperature pressing instrument, and the machine sent out the pressed PCB 2 minutes later.

Feng Chengxian took out the PCB board and couldn't help but frowned, because the films did not adhere well to the PCB board.

"Director Xu, these stacking films are not attached to the board." Feng Chengxian handed the PCB board to Xu Donghang and said.

Xu Donghang also frowned after taking over the PCB board. Could it be that the films mass-produced by Deep Blue Technology's machinery and equipment were not up to standard?
"Mr. Chang, you can see for yourself, these films are not attached to the board at all." Xu Donghang handed the PCB board to Chang Yongqing and said.

After Chang Yongqing took over the PCB board, he also saw problems on the PCB. The accumulated film did not adhere well to the PCB board. The film could be torn off by just pulling it lightly with your hands. Such a product is obviously not good. qualified.

"Director Xu, let me call and ask." Chang Yongqing said.

Xu Donghang nodded and didn't say much. Chang Yongqing was just a sales manager, so he probably didn't understand technical things.

Chang Yongqing walked aside and took out his mobile phone to dial Han Chen's number.

"beep beep beep"

The phone rang for more than a dozen times and Han Chen didn't answer the call.

This made Chang Yongqing extremely anxious. At the critical moment, the boss slipped up.

At this time, Han Chen was taking a bath in the bathroom and did not know that Chang Yongqing called him.

10 minutes passed.

Chang Yongqing was extremely anxious, but Han Chen just didn't answer the phone.

Chang Yongqing looked at Xu Donghang awkwardly and said, "Maybe Mr. Han was busy with something, so he didn't answer my call."

Before Chang Yongqing finished speaking, his cell phone rang.

Seeing that it was Han Chen calling him back, Chang Yongqing immediately pressed the answer button.

"What's the matter with Chang Yongqing calling me?" Han Chen asked.

"Mr. Han, we trial-produced a batch of deposition films last night. I sent some mass production samples to Shennan in the morning. However, our deposition films did not adhere well to the PCB board. Is there anything in it? What details need attention?" Chang Yongqing asked.

Han Chen also fell silent when he heard Chang Yongqing's question.

Logically speaking, according to the system production method, such problems should not occur.

"Don't hang up the phone yet." After saying this, Han Chen threw the phone on the bed.

Then he took off the bag containing the notebook from the hanger, and then Han Chen opened the notebook to check the information about the accumulated film.

"Tick tock ~ tick tock ~ tick tock"

Time passed by minute by minute, and more than ten minutes passed in the blink of an eye.

This situation made Chang Yongqing very embarrassed, but Xu Donghang didn't have many opinions. It is very common for new products to have minor problems.

"Chang Yongqing, what temperature did they use to suppress it?" Han Chen asked.

Chang Yongqing turned to look at Feng Chengxian and asked: "Master, what temperature did you use to suppress it?"

"The deposited film is pressed at a high temperature of 158 degrees." Feng Chengxian looked at Chang Yongqing speechlessly and said.

Isn’t it common sense to use a high temperature of 158 degrees to suppress the deposited film?
