The Black Tech Life of Scum

Chapter 21: : The haunting of the cottage team

一 大 The next morning, Zhang Yifan took Zhang's father to Tianshi.

张 While Zhang Yifan was buying components in the electronics city, a group of people sat in a conference room in the science and technology city of Nanshi.

"This thing is called a melon inspection artifact, it started to become popular on the vibrato, and the product was in short supply on Taobao."

"We also bought two, and requested SF, to be here this morning, I asked Xiao Li to go to the courier company to pick up the pieces!"

"I think this product has a certain market potential. The vibrancy of Douyin should continue for a short period of time. Some of you have worked harder these days. We need to copy it as soon as possible and then bring the product to the market."

Liu Jiang held a small black box in his hand and said to the sitting man.

"Zhang Gong has already taken one to open the shell. Everyone can see it for a while."

This electronics factory called Qichen Technology is actually a small factory. They do almost everything.

They are as large as LCD TV motherboards, OEMs such as mining machines, imitations of popular Internet celebrity products, imitations of home lamps, and even as small as chargers or even USB cables. As long as they have money to make them, they all do;

Without its own patch line, there is a patch factory in the industrial park;

I do not have the ability to launch products myself, but I can copy the board:

By disassembling and measuring, measure the parameters of each device to draw a circuit diagram, re-regulate the wiring on the PCB board, and delete or add some devices to avoid the risk of being sued for infringement.

Even if the chip is polished, the model of the chip can be judged from the circuit drawn;

Imitate the products of other companies, and then cancel some functional circuits, reduce the power of the device, replace the high-precision parts with low-precision parts, reduce testing, replace the original parts with poor-quality parts, etc ...

In order to reduce costs, improve market competitiveness, and even grab market share from original manufacturers.

For example, a well-known manufacturer of lamps uses isolated switching power supplies, well-known brands of LEDs, and uses a thick aluminum substrate to dissipate heat, and uses a 0.5 mm thick base, a high-transmittance mask, and then There is at least two hours of aging time, so the cost price is one hundred dollars.

However, after the imitation of Qichen Technology, the resistance-capacitance step-down circuit was used. The LEDs produced by small companies even had quality problems. The returned LED lamp beads were reduced as much as possible on the thickness of the aluminum substrate and base. Mask ...

Because the circuit becomes very simple, the number of components is reduced, and the process is simplified. The burn-in test is not performed directly. The cost of such a set can be reduced to less than fifty.

Introduced to the market, selling a sixty or seventy also has a profit;

Users don't know. Looking at the style is very good, the price is so much lower, and after comparing them, they can't see any difference, and many people have made a choice.

At least the light efficiency is low, there are micro-flashes, large power consumption, short life and so on. Most users will not notice it, even if they find it, they will not care too much.

This kind of edge zone is the soil where Qichen Technology lives.

When everyone was trying this melon tester, Zhang Gong with glasses went into the meeting room with the open melon tester.

"It came out," Zhang Gong said, "you didn't expect it. There is no PCB in this thing. Use the device feet to solder directly, and then fix it with hot melt adhesive."

I said that he put the box in the center of the conference table, and I also saw the way of covering the shell. It was not ultrasonic, but glued with glue such as 502.

"If we do, how much can the cost be reduced to?" Liu Jiang suddenly asked with interest.

"I don't know much about electronic devices, but the mechanical parts are two or three dollars." Zhang Gong said, "Ligong, look ..."

This company can be described as a small sparrow with all its internal organs. Because it has to make a variety of products, the division of labor within the company is also very clear.

Li Gong is the electronics engineer of Qichen Company. Competitive product analysis of friend products and cost reduction verification of the company's main products are all led by experienced Li Gong;

工 Li Gong picked up the melon inspector and glanced at it a little bit: "PIC16F?"

"What's wrong?" Liu Jiang asked.

"This thing is a microcontroller, this thing is a little weird," Li Gong frowned.

"The principle of this thing is actually to use the tapping effect of this switch to make a sound, then collect the sound signal from the microphone, and finally send the instruction to the voice chip."

所有人 Everyone in the conference room has his ears raised, because this thing is about their bonus.

可以 "It can be said that if the mechanical parts only cost two or three dollars, the overall cost of this product can be controlled below twenty dollars as long as we use PCB layout and partly replace the mounted devices."

"This is very good. There is enough profit space to seize the market for 35 yuan or even 30 yuan, and we can reduce costs again." Liu Jiang was excited.

"But I can't do it!" Li Gong spread his hands directly.

"You haven't tried it, you haven't even tested it, so you can't do it? This is not your style." Zhang Gong next asked.

"Let's put it this way, the principle of the voice chip is that a button on the toy can make a sound or sing a song. You must have told a story. A simpler is a calculator that can make sounds," Li said. Explained.

"This principle is to send a signal to the voice chip, and then it outputs the corresponding audio," Li Gong said, pointing to the chip that was glued to the box by the hot melt.

"This microcontroller now replaces the work of pressing a button by hand, and it can also judge the maturity of the watermelon by the received audio signal, or even the watermelon ..."

"If I didn't see the silkscreen on the IC, I would have thought it was a smart chip, because to realize this process, you need to collect huge data ~ www.wuxiaspot.com ~ and then compare it with the collected audio signals. carry out."

"In other words, the core part of this product is the program in this IC. I can't figure out how the designer edited the program. Using audio signals to input this IC that can only compare voltages, I can experiment with this one. process."

Li Gong sighed after saying: "I think the design team of this IC may not have thought of it, otherwise they should have used this as a selling point to launch the market long ago, and the overall microprocessor market structure may be changed ... . "

"If we don't use this chip, can we develop similar or similar products?" Liu Jiang asked.

"Yes," Li Gong said, "we first need to use an A / D converter, first convert the analog audio signal into a digital signal, and then input it into the microcontroller for comparison, and finally output the corresponding instructions to the voice chip. .... "

当然 "Of course, this IC is definitely not working. The number of light scores represents a huge amount of data. We need to use smart chips and matrix peripheral circuits ..."

"You directly talk about cost and R & D cycle," Liu Jiang said with expectation.

"The final cost price will be about 80 to 100 yuan a single ... the platform construction and debugging time will take about two or three months," Li Gong thought and said.

"Xiaoai Smart Bluetooth speaker is only two hundred dollars. You said you need more than one hundred yuan to make a melon tester? Who would buy it? And two or three months after the launch, day lily is cold." Liu Jiang said, Then he asked unwillingly, "Can't you be sure of this IC?"

工 Li Gong shook his head: "I don't know where to start with this IC, unless he can get the source program he programmed ..."
