"What's going on?" Hu Rui asked after walking to his colleague.

"The design of this circuit board is really good. I have never seen a domestic recorder with such a good circuit layout." Said one of the middle-aged men wearing black-rimmed glasses.

"It looks like the product of a big factory. The circuit boards are arranged very neatly, and the soldering is also very good. The size of each solder joint is very consistent. This requires a very high-tech worker to achieve it." Another expert also said. .

"This..." Hearing this, Hu Rui reached out to pick up the circuit board and looked at it carefully.

For experts in electronic products like them, they are well aware of the development of the domestic electronic industry. Because of their work, they have to contact hundreds of thousands of products every year, test and evaluate them, so that they only need roughly With a glance, they can know the grade of this product.

As far as domestic tape recorders are concerned, many of them are made of horse dung eggs with a smooth surface, and the outer shell looks very delicate, but the circuit boards inside are another situation. The arrangement of the circuit boards is dense and chaotic. If it is not closed, the size of the solder joints is inconsistent, and it looks like a piece of bird droppings on it, which is easy to cause solder joint corrosion and leakage.

This kind of situation is actually common in domestic electronic products, and the reason is very simple, because the original circuit boards in China are all hand-soldered. Due to the differences in the technical proficiency of workers, the state-owned large factories are better, and there are more old workers, so The quality is relatively better, but for some small private factories, the training time is relatively short, and they often work overtime to catch up with work, unskilled technology, and physical exhaustion make it difficult to control the quality of circuit boards, and quality problems are prone to occur.

And the circuit board of this tape recorder looks very beautiful indeed. All the electronic components are neatly arranged, the spacing is dense and uniform, the solder joints are all the same size, and the level of craftsmanship is quite high.

"...This should be a circuit board processed by a plug-in machine. It is impossible to arrange it so neatly by hand." Hu Rui quickly made his own judgment, only to hear him say in surprise: "But as far as I know , Among our domestic electrical appliance manufacturers, only BJ and the TV factory in Shanghai use plug-in machines. I really didn’t expect that someone in the electronics factory in Shenzhen would use automatic equipment to make tape recorders..."

As an expert of the National Ministry of Electronics Industry, Hu Rui's vision is still very poisonous. Based on his experience and insight, he can tell at a glance that this is definitely not a circuit board made by hand.

Speaking of equipment such as plug-in machines, it is not that there are no such equipment in China, but there are very few manufacturers with such equipment.

Because there are a lot of electronic components that need to be welded on the TV circuit board, they are technically more complex and sophisticated than other electronic products. Any problem with any of the hundreds of electronic components will cause serious quality problems. Manual installation and welding Circuit boards are slow, and quality control is difficult. It is precisely because of this that there are very few manufacturers that can produce domestic TV sets, far fewer than electronics factories that produce tape recorders and radios.

Therefore, after BJ TV Factory introduced Japanese TV production line for the first time in 82, it began to use equipment such as plug-in machines. Later, Shanghai TV Factory also introduced plug-in machine technology, but generally speaking, it is possible to use this The manufacturers of the equipment are all national key TV factories.

So when Hu Rui saw that some tape recorder manufacturers also used plug-in machines, he must have been very surprised and unexpected.

"What? Is this product good?" Mayor Liang Xiang who followed behind asked.

Seeing that the recorder products in his city can be recognized by BJ experts, Liang Xiang naturally feels proud. This at least shows that the technology of Shenzhen's electronics industry still has merits in China.

"This circuit board is really well made... Hey? I think there is only one driving motor. Is this really a dual-card recorder?" Hu Rui quickly discovered the structure of the transmission part behind the circuit board, and was immediately surprised Said.

"The products for this competition are all 300-600 yuan dual-card recorders produced locally in Shenzhen, that's right." A person next to him said.

"Single motor drives a dual-card recorder?" Hearing this, not only Hu Rui, but also several other reviewers were surprised.

According to the understanding of Hu Rui and others, there are currently some dual card recorders driven by a single motor in the world, but there are very few such products, and they only appear on Japanese recorders. There is no such single motor in China. Manufacturers that drive dual-card recorders, and even some single-card recorders from Japanese manufacturers use two micro-motors in order to achieve functions such as rewind speed and recording. Dual card recorder.

"Mayor Liang, your organizing committee must have made a mistake, right? Is this really not an imported tape recorder?" After a while, Hu Rui turned to Liang Xiang and asked.

Seeing that the circuit board is so neat, and it is a dual-card recorder driven by a single motor, Hu Rui soon suspected that the product presented at the exhibition might be an imported recorder, because even in the national recorder quality evaluation, they I have never seen a recorder product with this level of craftsmanship and technology.

"It's impossible to make mistakes. Our SZ city government has been preparing for this competition for a while. All the products and the list of manufacturers have been strictly and repeatedly reviewed. The products submitted are also checked by a special person. It should be Such a mistake is impossible." Liang Xiang said with a serious face.

"Take a look at the shell of the product." Hu Rui said to the colleague next to him.

"This is it." A person next to him handed the casing of the tape recorder to Hu Rui.

"This is... Tianyin colorful brand? Is this a product of your Shenzhen Electronics Factory?" Hu Rui asked after looking at the label on the casing of the recorder.

"So this is the Tianyin colorful tape recorder?" After hearing the words, the people nearby also asked in surprise.

Hu Rui himself is busy at work, and in the past two months, he has mainly focused on the formulation of new technology standards for domestic TV sets, so he has not paid attention to the Tianyin colorful series of tape recorders that are currently being advertised overwhelmingly in domestic media.

However, several of Hu Rui’s colleagues have often seen advertisements for the products of Duanyun Electronics Factory recently, especially Pan Hong and Liu Xiaoqing successively endorsed the tape recorder, which made the colorful tape recorder unprecedentedly famous in China. The area is also very popular. Walking on the street, you can often see some young people carrying this small tape recorder, which is very fashionable.

And after learning that the tape recorder product praised by BJ experts was actually a new product produced by Duan Yun Factory, Liang Xiang couldn't help being surprised, but soon, he straightened his back and put a few words on his face. Very proudly said:
"That's right, this is our recorder product produced in Shenzhen!"
