Are you also wondering - the overwhelming advertisements of LED manufacturers on the Internet all say they are "source factories", but the price is two or three times the difference? What’s even more evil is that some salesmen said “shipped in three days” while they were not seen for half a year! Today, let’s open this layer of window paper to let you see through the industry’s old foundation!

1. The "Golden Triangle" on the map"

Anyone who works in this industry knows it.​​Pearl River Delta, Yangtze River Delta, and southeast Fujian​​There are real dragons hidden in these three realms. What do you think? More than 70% of LED modules in the country flow out from these places!

To give a practical example: In an industrial park in Shenzhen, the entire process can be completed in ten minutes by walking from chip patches to finished product testing. You can still hear the loading and unloading of trucks here at 3 a.m., why? ​ ​The supporting radius is compressed to within 5 kilometers​​Even the packaging box factory squats on the street next door! Data shows that the raw material procurement cycle of the manufacturers here is 5 working days faster than that of the mainland, and it is really possible to deliver the goods in three days when the urgent order is urgent.

2. The three birthmarks of the real source factory

​​1. The workshop hides the "money printing machine"​​
Don’t trust those who dare to call themselves factories if you rent a warehouse! Real guys need the following configuration:

• ​​Fully automatic patch machine​​(23% higher yield rate than manual welding)
• ​​Aging test room​​(The continuous roaster will be considered passing for 48 hours)
• ​​Spectroscopy analyzer​​(Million-level equipment, color difference cannot escape its vision)

Last year, a customer was cheated - the screen broadcast I bought was always orange. Later, I found that the manufacturer did not have any color calibration equipment at all, so I used the mobile app to adjust the color!

​​2. Quality inspection is stricter than mother-in-law​​
Have you ever seen a solder joint check with a microscope? The real source factory just does this! Their quality inspection list can scare people:

• High and low temperature cycle test (-30℃ to 80℃ back and forth)
• Salt spray corrosion test (must-have for seaside projects)
• Vibration simulation test (to ensure that transportation does not fall apart)

A northern customer found a small workshop for cheap photos, but the screen was shipped to Inner Mongolia and the screen was black when it was minus 40℃. It cost 120,000 more to return to the factory to rework!

​​3. 24 hours" Emergency Room"​​
What should I do if the control system is exhausted at 2 o'clock in the middle of the night? Hardcore manufacturers dare to hang the number of online engineers on the official website. The most awesome operation I have ever heard of - a Dubai customer's screen is flooded, and the technical team knocked away with accessories, landed and went straight into the computer room for repair!

3. Price breaking fog: Save the cost like this

1. ​​Direct chip picking is really​​
   Some manufacturers' "imported chips" are actually wholesale in Shenzhen Seg market! Real big guy signs the New Year box with Japanese and Korean chip factories directly.​ ​Purchase price can be reduced by 15%-20%​​A certain manufacturer uses this trick to achieve a P2.5-pitch screen of 6,800 yuan per square meter.

2. ​​Logistics network laying hidden lines​​
   Don't underestimate this! Manufacturers who set up transit warehouses in Southeast Asia can reduce the shipping time by 5 days. Last year on Double Eleven, an e-commerce company temporarily added 2,000 square meters of orders. The manufacturer transferred goods from a Vietnam Warehouse and delivered them on the deadline.

3. ​​Scrap recycling makes dark money​​
   Scrap materials and bad products are treasures in the hands of experts! Some factory melted the scrap frame and recast it.​ ​Save two factory rents in a year​​. However, this matter requires excellent skills, and the strength of the recycling materials cannot withstand the typhoon.

4. Soul interrogation time

​​Q: How to verify whether it is the true source? ​ ​
A: I will teach you three ruthless tricks:

1. Video link to see production (note the floor of the workshop - the floor glue of the real mass-produced factory has been ground long ago)
2. Check customs export data (annual shipment volume exceeds one million US dollars)
3. Raw material customs declaration form (the purchase orders of Japanese and Seoul chips cannot be fake)

​​Q: Everyone says that they are the first-hand price, who do you believe in? ​ ​
A: Look at the speed of product iteration! Zhenyuan Factory will update its product line in the quarter, and those who have not changed their appearance for three years are probably slander. A customer found that the price difference between the two companies was 40%, but when he went to the factory, he saw that the low price was using old molds from five years ago!

​​Q: How do you look at the strength of whether you are customized or not? ​ ​
A: Two key questions:

• Have you ever made a special screen (arc and spherical shape are touchstones)
• Do you dare to change parameters on the spot (real technology can adjust the gamma value on the spot)

The editor said it's heart-to-heart

After working hard in this industry for more than ten years, I have seen many tricks of selling dog meat with the help of sheep. I want to say it​ ​Looking for a factory is like taking the pulse of a traditional Chinese medicine doctor - you have to look, listen, ask, and touch​​! When you are in the next inspection, remember to bring three magic weapons: strong light flashlight (lighting the structural gap), magnifying glass (seeing the uniformity of the solder joint), and thermometer (measure the effective heat dissipation).

Finally, I will get a hard-core data: a truly capable manufacturer starts with a workshop equipment investment of at least 50 million yuan, and a monthly production capacity of less than 10,000 square meters will not dare to speak loudly. You taste, you taste...
