Important production process of LED lamp beads: raw material: LED bracket, LED chip, LED solid crystal glue, gold wire, LED packaging glue, LED fluorescent powder, etc. LED lamp beads production equipment: automatic crystal machine, plasma washing machine, automatic welding machine, automatic point -liquid machine, glue mixer, oven, splitter, automatic sorting machine, automatic packaging machine, automatic packaging machine. Production environment: LED lamp beads need to perform excellent electrostatic protection throughout the process, because LED chips are afraid of static breakdown. Important production steps: 1. LED bracket inspection. Important inspection project: appearance size, electroplating thickness, whether the oxidation phenomenon LED lamp bead isolation paper. 2. LED bracket baking. Use the device to bake the LED lamp bead bracket. It is important to remove the water vapor remaining during the injection process during the injection process. 3. LED bracket plasma wash. Purmake washing is important to form an arc inside the equipment by hydrogen and oxygen, remove the organic matter residual of the LED bracket appearance, and improve the bonding force of solid crystals. 4, solid crystals. Put the LED chip with LED solid crystal adhesive on the LED bracket with the automatic solid crystal machine. 5. Baking. Bake the solid crystal glue and let the LED chip and LED bracket form a fine bonding. After the baking is finished, the solid crystal thrust test should be performed. 6. Golden line overlap. Weld the pads on the LED chip and the conductive area on the LED bracket with gold wire for welding. Several types of welding: golden silk spherical welding, wedge -shaped welding. The metal wires used are: gold, aluminum lines, alloy lines, copper wires, etc., LED lamp beads are important to use gold, alloy lines, and copper wires. After the welding is completed, the welding point must be measured and welded. 7. Sealing. LED packaging glue formed in the cup -shaped area formed by the LED bracket is filled. If it is made of white LED lamp beads, the appropriate amount of fluorescent powder needs to be added to the packaging glue. This step is the step to produce white light, but also the steps that determine the color temperature, showing fingers, and various colors. Companies that produce white light beads will have a special person with fluorescent powder. 8. Baking. Clean the LED packaging glue through the oven for. 9. The LED bracket cuts from many sections connected to the way, cut into an independent small unit for LED lamp beads. 10. Sort. Each cut small lamp bead is set for various parameters: voltage, color temperature, light flux, etc. 11. Packing. Packaging the lamp beads with no different parameters. --- The article comes from LED lamp beads, please indicate Tongjia (China) www.tongjialed.com
