The entire production process of plug-in LED lamp beads is divided into epitaxial chip consumption, chip consumption, and lamp bead packaging. The entire process reflects the level of modern electronic industry manufacturing technology. LED manufacturing is a fusion of multiple technologies and a high-tech product. Understanding the knowledge control of LED for lighting purposes is also necessaryInsert LED BeadsHow is it produced.

1. Production process of plug-in LED bead epitaxial wafers:

The LED epitaxial wafer growth technology mainly uses the Organometallic chemistry phase stacking method (MOCVD) to consume synthetic materials with semiconductor characteristics, which are the raw materials for manufacturing LED chips

2. Production process of plug-in LED bead chips:

LED chips are manufactured using epitaxial wafers and are devices that provide LED bead packaging, which is the key to the quality of LED beads.

3. Production process of plug-in LED lamp beads:

The packaging of plug-in LED beads is based on the usage requirements of LED beads. The chip is packaged on the corresponding bracket to complete the manufacturing process of LED beads. LED packaging determines the cost-effectiveness of LED beads and is the key to the quality of LED lighting products,

What is the manufacturing process of LED lamp beads

Choose the appropriate size, luminous rate, color, voltage, and current chip for LED packaging process. 1. Expand the crystal by using an expansion machine to evenly expand the entire LED chip film provided by the manufacturer, so that the tightly arranged LED grains attached to the film surface are pulled apart for easy crystal growth.

2. Back glue, place the expanded crystal ring on the back glue machine surface with the silver paste layer scraped, and apply the silver paste on the back. Point the silver paste. Suitable for bulk LED chips. Use a dispensing machine to apply an appropriate amount of silver paste onto the PCB printed circuit board.

3. Fix the crystal, place the prepared silver paste expansion ring into the crystal rack, and the operator will use a crystal pen to prick the LED chip onto the PCB printed circuit board under a microscope.

4. Crystallization: Place the PCB printed circuit board that has been punctured into a thermal cycling oven and let it stand for a period of time at a constant temperature. After the silver slurry solidifies, remove it (do not leave it for a long time, otherwise the LED chip coating will turn yellow and oxidize, making it difficult to solidify). If there is LED chip bonding, the above steps are required. If only IC chip bonding is required, the above steps will be cancelled.

5. Wire bonding, using an aluminum wire bonding machine to bridge the chip (LED grains or IC chips) with the corresponding solder pad aluminum wire on the PCB board, that is, to weld the inner lead of the COB.

6. Initial testing, using specialized testing tools (with different equipment for different uses of COB, such as high-precision stabilized power supply) to test the COB board, and repairing the unqualified board.

7. Glue dispensing: Use a dispensing machine to apply an appropriate amount of AB glue to the LED grains that have been bonded. The IC is packaged with black glue, and then stop the appearance packaging according to the customer's request.

8. Curing: Place the sealed PCB printed circuit board or lamp holder into a thermal cycling oven and let it stand at a constant temperature. Different drying times can be set according to the request.

9. Overall testing, use specialized testing tools to stop the electrical performance testing of the packaged PCB printed circuit board or lamp holder, and distinguish between good and bad.

10. Divide light, use a splitter to distinguish the brightness of lights with different intensities according to the request, and package them separately. 11. Warehousing. Afterwards, we will go out in batches and make contributions to the people

The above is my answer to the questions and related questions about the production of plug-in LED beads and how to make LED beads. I hope it will be helpful to you.
