Yang Ling has been designing the circuit motherboard diagram of VCD. Although the circuit diagram is very simple, it is very difficult to integrate all brands so that all brands can plug and play.
So Yang Ling didn't finish it until 3 o'clock in the morning the next day.
Yang Ling didn't have time to be gentle with Su Yi at night, but Su Yi understood this very well. She made Yang Ling a cup of warm milk and stayed by his side, and finally lay down on the table and fell asleep.
On the morning of the second day, Su Yi made breakfast and then went out to buy groceries.
Yang Ling took the designed circuit diagram and prepared to buy some raw materials and try to produce one himself.
If production can be successful, it will not be too late to find a way to find a factory to purchase raw materials in large quantities.
The raw materials Yangling needs include PCB boards, copper wires, copper plates, copper foil, as well as some electronic components and some materials that corrode circuit boards.
If Yangling has a standard factory, it can produce in large quantities.
But it is a pity that he does not have the strength to build a standardized factory now, so he can only start from a small workshop.
Yang Ling rode his bicycle to many electronic component shops in the city.
But it is a pity because Jiangcheng is a small county and there is no PCB board factory or related sales points.
Sweat had soaked Yang Ling's clothes. Yang Ling parked her bicycle on the side of the road and went to the grocery store to buy a bottle of Wahaha mineral water.
Gu Gu Gu Gu drank two mouthfuls of water, which made the whole body feel better.
At this time, Yang Ling had some doubts about life. He wondered whether his entrepreneurial route was wrong.
Being in the IC industry is indeed my strong point, and I am sure I can make money.
It's just because Jiangcheng County is really too backward.
Of course Yangling can now go to coastal areas, especially Guangzhou, to find factories for cooperation.
However, these factories all cooperate with large companies. For small customers like Yangling, one is unwilling to cooperate, and the other is expensive.
It is impossible for Yang Ling to invest all his money in it. If the investment fails, the money will be wasted, and it will be a waste of time.
So Yang Ling's plan is to first establish a presence in Jiangcheng or Jiangzhou, and then find cooperation with big manufacturers.
Only in this way can you be foolproof.
At this moment, an old man collecting scraps walked past Yang Ling.
He was riding a dirty tricycle with a flat tire on one side.
The old man saw the mineral water bottle that Yang Ling had finished and asked, "Young man, do you still want this bottle?"
Yang Ling still respects the working people very much.
No matter what kind of job the other party does, as long as they earn a living through their labor, they should be respected.
Yang Ling politely tightened the cap of the mineral water bottle, handed it to the old man and said, "Thank you!"
Yang Ling's move surprised the old man.
Generally speaking, people in the county look down on garbage pickers.
The old man has picked up a lot of garbage and also picked up many mineral water bottles.
Many people threw the mineral water bottles on the ground casually, and even disliked the old man's outfit and walked away. What's more, they may even directly insult the old man.
But this was the first time the old man encountered someone like Yang Ling who politely screwed on the cap and handed it over.
The old man smiled sheepishly and took the mineral water bottle.
Yang Ling was about to get up, leave on his bicycle, and continue looking for raw materials.
If that didn't work, he planned to take a bus to Jiangzhou to have a look.
After all, Jiangzhou is a provincial capital city, and it should have the raw materials Yangling needs.
Just when Yang Ling was about to leave, he suddenly saw several linen bags behind the old man's tricycle.
There are several green boards in the linen bag.
From this look, it should be a PCB board.
There are many types of PCB boards, the conventional one is circuit base material plus copper clad laminate.
These thick-looking green boards should be fiberglass cloth substrates, which are the ones commonly used in home appliances.
Yang Ling quickly asked the old man: "Old man, where did you get these boards?"
The old man said seriously: "Isn't there an electromechanical factory in front of me that went bankrupt? All the equipment was sold as scrap metal. Only these few boards are left. There are some copper wires on them, but not much."
"I'm going to go home and get these colleagues down."
"Plastic boards don't seem to be very valuable."
The old man laughed twice and said, "Earn some hard-earned money."
The current price of scrap copper should be several yuan per pound. If the old man pulls out these copper wires, the price may be a little more than a pound at most.
It's true that you can't find anything without wearing iron shoes, and it doesn't take any effort to get it.
Yang Ling searched for a long time but couldn't find it, and actually found it among the old man collecting scraps.
Yang Ling suddenly thought that some electronic components might be found at the old man's place.
Yang Ling quickly said to the old man: "Old man, what is your surname?"
The old man smiled cheerfully, showing his dark teeth, "It's expensive, it's not expensive at all. My name is Chen Sangen."
"Old man, how much do these boards cost?"
Yang Sangen thought for a while and said, "How many boards do you want to eat? This one is made of copper wire, so I'll charge you two yuan!"
Without saying a word, Yang Ling took out 5 yuan from his bag, handed it to Chen Sanhe and said, "Do you know where the biggest waste station here is? Can you take me to take a look?"
After borrowing enough money, Chen Sangen said cheerfully: "It's right here in our village in the city. Come on, you come with me."
Soon the two came to the village in the city.
This is the dirtiest and messiest place in Jiangcheng County, and it is also a place that is lagging behind in the process of urbanization.
Yang Ling first followed Chen Shan to where he lived. There were a lot of waste piled up in Chen Shangen's home.
Of course, this also includes electronic waste.
Some of these electronic scraps are left over from used electrical appliances, and some are discarded from factory equipment near Jiangcheng.
Yang Ling rummaged through it at will and found that many things were quite useful.
For example, there are some circuit boards in which the electronic components are not broken at all.
On the scrap side, these circuit boards will be sold as scrap metal, which is quite a pity.
Yang Ling picked up a lot of raw materials that he could use, and then said to Chen Sangen: "Uncle Chen, sell these things to me, do you think it's okay?"
Chen Sanjie looked at these electronic wastes and felt that they were not worth much.
After all, the most valuable items for scrap collectors are metals such as copper and aluminum, followed by iron, and then paper shells and cardboard.
The price of recycling plastic products is not high, and these electronic products can only be sold by removing the metal on them.
Chen Sanhe said very cheerfully: "I'll charge you five yuan for these too."
Yang Ling was ecstatic. These circuit boards and electronic components can basically be used as a VCD circuit motherboard, but there are some special materials that Yangling does not have here yet.
But Xu Wenshan must have them there. Xu Wenshan had a lot of old and useless VCD parts, and he had no use for them. They just threw them into the trash can or sold them to scrap recycling stations.
Just buy the electronic components and you're ready to use them.
Of course, it's still the same sentence, Yang Ling can never treat these waste products as raw materials.
What he wants to do now is to use these waste products, and it is his circuit diagram that is correct.
As long as this step is taken and there is a profit opportunity, then you can find a coastal electronic component factory and purchase a large amount of raw materials to start a business.
"Uncle Chen, do you think this is okay?" Yang Ling said: "In the future, if you can recycle such circuit boards or electronic components, bring them to me. The price I will give you will definitely be higher than the price you sell to the scrap recycling station.
Much higher."
Uncle Chen was so happy that he showed his dark teeth and said: "It's such a good relationship. I haven't thought that these plastic pieces are treasures!"
