I heard that many people are inquiring about the location of Ledu LED factory recently? This is like looking for a partner - you need to know where the other person lives, how many people live in their family, and whether they are trustworthy. Today we will take you on a tour of the factory, so that you will have a clear understanding after reading it.

1. Factory location selection hides university knowledge

You may not know that serious LED manufacturers must consider these three "vitals" when selecting locations:

• ​​Cannot be more than 200 kilometers from the port​ ​: It is convenient to import raw materials and export finished products (sea transportation cost can be saved by 15%)
• ​​There must be a complete industrial chain around​ ​: Hardware, chips, and packaging supporting companies must be complete
• ​​Must avoid earthquake zones​ ​: Precision equipment cannot withstand being wandered around for three days.

To give a real case, a certain brand built a factory next to a logistics park. As a result, floods poured in during the rainy season, and inventory worth tens of millions was wiped out. So,​ ​Factory location directly determines product stability​​。

2. Specific coordinates starting from the bottom

According to industry veterans, reliable LED factories are basically clustered in three areas:

1. ​​Pearl River Delta Industrial Belt​ ​: Especially around Shenzhen, where 70% of the country’s LED upstream and downstream companies are concentrated.
2. ​​Yangtze River Delta Science and Technology Innovation Circle​ ​: Nanjing and Suzhou focus on high-end customized screens
3. ​​Chengdu-Chongqing Transportation Hub​ ​: Logistics distribution center for projects in the central and western regions

A company that has been deeply involved in the industry for more than ten years has built a 100,000-level dust-free workshop in Bao'an District, Shenzhen. Why choose here? It takes five minutes to get on the expressway and half an hour to the port. Next door is a chip supplier, and even the packaging box factory is in the same industrial park.

3. Five-piece set necessary for factory inspection

If you really want to go on a field trip, remember to bring these equipment:

• ​​UV flashlight​ ​: If you look at the joints of the box, genuine waterproof glue will reflect light.
• ​​micrometer​ ​: Measure the thickness of the cabinet and pass on the spot if the error exceeds 0.5mm.
• ​​Thermohygrometer​ ​: Check whether the workshop has constant temperature and humidity (25±2℃, humidity ≤60%)
• ​​Static electricity bracelet​ ​: Test anti-static measures are not in place
• ​​magnifier​ ​: Check whether the lamp bead solder joints are full and even

Last year, a buyer went to inspect the factory and found that the lamp beads in the material preparation area were piled directly in cartons without being stored in moisture-proof cabinets, so they decisively canceled an order worth two million.

4. Hidden secrets of the production line

When entering a regular workshop, you have to focus on these links:

1. ​​SMT workshop​ ​: Is the fully automatic placement machine a brand such as Yamaha/MRSI?
2. ​​Aging test area​ ​: At least 72 hours of continuous power-on test
3. ​​Quality inspection station​ ​: Is there an AOI automatic optical detector?
4. ​​Packaging line​ ​: Is the anti-shock material made of pearl cotton + customized foam?

An expert told me that the material racks in good factories are managed according to color zones - the red area is for defective products, the green area is for products to be inspected, and the yellow area is for urgent items, which is neater than supermarket shelves.

5. Personal point of view time

Let me tell you, looking for an LED factory now is like choosing a hospital - you can't just look at the size of the billboard, you have to look at whether the "operating room" is clean. Some small workshops have decorated their showrooms to look like Apple flagship stores, but the actual production lines are still using old equipment from ten years ago.

It is recommended that you focus on three points during your on-site inspection:​ ​Material management details, quality inspection process thickness, and technician age​ ​. I have seen an old factory where the director of the patch shop has been working for twelve years. He can hear abnormal noises from the equipment with his eyes closed. This accumulation of experience is the real guarantee.

A final reminder: Don’t believe the trick of “showing you the factory”. Some agencies rent factories specifically for customers to visit. If you really want to verify your identity, you have to check whether the business license address is consistent with the actual location. It is best to conduct a surprise inspection so that you can see the most realistic production status.
