Do you think that all LED manufacturers across the country are hiding in nooks and crannies? Let me tell you a little trivia - one out of every three LED screens in the world comes from Bao'an District, Shenzhen. Last month, a customer from Northeast China came for inspection. As soon as he got off the plane, he was dazzled by the LED billboards from the airport to the industrial area. The display was even more exaggerated than Las Vegas.

▎​​A secret base where manufacturers gather together​​
Shiyan Street, Baoan District, Shenzhen, hides the densest LED industry chain in the world. Starting from Huike Industrial Park, you can see more than 20 display screen factories in a ten-minute drive. This kind of industrial cluster did not form by accident:

1. ​​Complete supporting industry chain​ ​(Find all chips, driver ICs, and box materials within three kilometers)
2. ​​Technical talents gather together​ ​(There are more than 30,000 hardware engineers alone)
3. ​​Lowest logistics cost​ ​(The drive to Yantian Port is faster than having a hot pot meal)

The manufacturer that installed fence screens for the Tokyo Olympics last year came from this industrial area. I have been to their workshop. The fully automated assembly line looks like a Transformer. It takes ten minutes to put together a P2.5 rental screen.

▎​​What hard indicators should be considered when selecting a site? ​ ​
→​​Must bring automated workshop​ ​(Only factories with a monthly output of more than 10,000 square meters have strength)
→​​Quality inspection laboratories are indispensable​ ​(The aging test takes a full 72 hours)
→​​No more than 50 kilometers from the port​ ​(Manufacturers with many export orders understand this principle)

Last month I met a novice buyer who insisted on looking for "factory direct sales" in the suburbs. It turned out that the factory didn't even have a reflow soldering machine, so they used a soldering iron to solder the lamp beads manually. The screens produced by this kind of workshop would definitely develop pitting after three months.

▎​​The three most common pitfalls for novices​​
Q: Does a cheap price mean a good factory?
A: Wrong! Really good factories dare to show you ISO9001 certification and full inspection reports, and some will take the initiative to take you to the aging room to see the stress test.

Q: The bigger the factory, the better?
A: It depends on the condition of the equipment. I have seen factories with an area of ​​8,000 square meters still using placement machines from five years ago. This kind of production capacity is useless no matter how large it is.

Q: Are manufacturers with more exports more reliable?
A: That’s half true. Factories that can export to Japan and South Korea for a long time do have good quality (their acceptance standards are strict), but be careful that some factories use orders from Southeast Asia to fill up their sales.

▎​​New trends in site selection in the next five years​​
Now smart manufacturers are starting to play the "dual base model":

1. ​​Shenzhen headquarters engages in R&D​ ​(Understand cutting-edge technology)
2. ​​Set up branches in inland cities​ ​(Labor in Hubei and Jiangxi is 30% cheaper)
3. ​​Direct shipping from overseas warehouses​ ​(Set up warehouses in Bangkok and Ho Chi Minh to shorten delivery time)

There is a manufacturer of stadium fence screens. After moving its production line to Changsha last year, its logistics costs dropped by 18%, and it can also radiate to the entire Central China market. This kind of flexible layout is the future trend.

The editor has two final words: Don’t just read the manufacturer’s brochure, pay attention to three points during the on-site inspection - whether the workshop has an anti-static floor, whether the quality inspector is fishing, and whether there is a lot of backlog in the warehouse. If you see a factory with a monthly output of more than 10,000 square meters in an industrial park in Bao'an District, with more than a dozen container trucks parked at the door, you are right to cooperate with this kind of manufacturer with your eyes closed. I heard that 80% of the high-end screens currently exported to Japan come from the factory building on Xixiang Avenue in Shenzhen. The workshop is so clean that it can be used as an operating room. This is called professional style!
