Hello everyone, I am a dream. Today, let ’s introduce the problem of how to produce LED lamp beads for automatic LED lamp beads. Here are a dream to summarize this issue and related issues. Let’ s take a look. Catalog of the article:1. LED lamp bead production process 2. How to process LED lamp beads 3. How to produce LED lamp beads 4. How does LED lamps produce? LED lamp bead production process First of all is the molding pin, then fix the spacing spacing through the machine, and then welded the chip (glowing things), welded the gold wire, and then injected the resin in a mold, and then then Pour the welded pins and wafers, then insert it into the mold, bake, mold, and then make the crystal generally buy it directly LED lamp beads The first step : Expansion. Use the expansion machine to evenly expand the entire LED chip film provided by the manufacturer, so that the LED grains that are attached to the surface of the thin film are opened, which is convenient for thorns. Step 2: Back glue. Put the expanded crystal loop on the gum with the gels of the silver paste layer, and the silver pulp on the back. Order silver pulp. Suitable for bulk LED chips. Use the point -to -point silver slurry point on the PCB printing line board.3rd step: Put the splashing ring prepared by the silver pulp into the spines, and the operator puts the LED chip under the microscope on the PCB printing line. Step 4: Put the spiny crystal PCB printing line board in a hot circulating oven for a period of time and rest for a period of time. Bang Ding is difficult). If there is a LED chip state, the above steps are required. If only IC chips are fixed, the above steps are canceled. Step 5: Adhesive chip. Use a point -to -PCB printing line board to print an appropriate amount of red glue (or vinyl), and then use the anti -static equipment (vacuum suction pen or child) to correctly put the IC nude on the red glue or vinyl. Step 6: Dry. Put the sticky nude in the hot circulation oven and place it on the large level of the heating plate for a period of time. It can also be naturally solidified (long time). Step 7: Bangding (Playing line). The chip (LED grain or IC chip) is used to bridge the chip (LED grain or IC chip) with the pads of the PCB plate, that is, the internal lead welding of the COB. Step 8: Pre -test. Use a dedicated detection tool (COB according to different uses has different devices, simply high precision voltage voltage power supply) to detect the COB board, and repairs the unqualified boards. Step 9: Point glue. Use the point -to -replenishment machine to put the mixed AB glue in an appropriate amount to the well -fixed LED grains, and the IC is encapsulated with vinyl, and then the appearance is encapsulated according to the customer's requirements. Step 10: CIT of. Put the sealing rubber PCB printing line board in the hot circulation oven, the constant temperature static, and different drying time can be set according to the requirements. Step 11: After testing. The encapsulated PCB printing line board is then tested with a dedicated detection tool to distinguish between good and bad. LED lamp bead's entire production process is divided into extension sheet production, chip production, and lamp bead packaging. The entire process reflects the level of modern electronic industry manufacturing technology. The integration of a variety of technologies is a high -tech product. The knowledge of LEDs for lighting also needs to understand how LED lamp beads are produced.1. LED outer extension production process: LED extension film growth technology mainly uses the synthetic material produced by organic metal chemical deposition (MOCVD). Process:LED chip is made of extension, which is a device that provides LED lamp beads. It is the key to the quality of LED lamp beads. 3, LED lamp bead production process: LED lamp bead is encapsulated according to the use requirements of LED lamp beads, the chip is encapsulated on the corresponding bracket to complete the manufacturing process of LED lamp beads. It is the key to the quality of LED lamp products. LED light how to produce what machines need (expand the chip to open, easy to solid crystal)-a microscope (need to be amplified when solid crystals)-baking machine (After each process is completed, it must be baked) -The welded wire (chip and bracket conductivity) -the point-tube machine (white light needs to be used, Puguang is not used) -the vacuum machine )--the irrigated machine (for the sealing of the seal)-the excrement (detecting whether the lamp beads are poor and the leakage)-cutting machine (one set of one set in front and back) -thery machine Use) LED lamp manufacturing process is divided into the following steps: chip, bracket, and silver gum are the basic components of a LED lamp. The chip needs to expand the crystal to facilitate installation, the bracket needs to be cleaned, the freezing silver gum is warmed back, etc. The whole process can be according to the steps shown in the figure, but it should be noted that the two are more important in the two stages of solid crystals and welding lines. A step of. After the lamp beads are done, the assembly of the lamp is basically not difficult, and the assembly methods of different manufacturers are different. The lamp source materials and assembly methods used directly affect the quality of the lamp. LED lamp bead production processLED packaging process is good, light, luminous, color, voltage, current chip, 1, crystal, and use the expansion to use the entire LED chip film provided by the manufacturer evenly evenly Expansion, the LED grains that are attached to the surface of the film are opened tightly, which is convenient for spiny crystal. 2, gel back, put the expanded crystal ring on the back glue machine with the silver paste, and carry the silver pulp on the back. Order silver pulp. Suitable for bulk LED chips. Use the point -to -point silver slurry point on the PCB printing line board. 3, solid crystal, put the diaphragm of the silver pulp into the thorns, and the operator put the LED chip with a thorns in the PCB printing line under the microscope. 4，定晶，将刺好晶的PCB印刷线路板放入热循环烘箱中恒温静置一段时间，待银浆固化后取出(不可久置，不然LED芯片镀层会烤黄，即氧化， It causes difficulties to the state). If there is a LED chip state, the above steps are required. If only IC chips are fixed, the above steps are canceled. 5, welded wires, use aluminum wire welding wires to bridge the chip (LED grain or IC chip) with the corresponding pads of pads on the PCB board, that is, the internal lead welding of COB. 6, initial test, use a dedicated detection tool (COB according to different uses, there are different devices, simply high -precision voltage voltage power supply) to detect the COB board, and repairs the unqualified boards. 7, point adhesive, use the spotted machine to put the mixed AB glue in an appropriate amount of AB glue to the Ding -fixed LED grains, IC is packaged in vinyl, and then encapsulates according to the customer's requirements. 8, solidify, put the sealing glue PCB printing line board or lamp seat in a hot circulation oven, restore the constant temperature, set different drying time according to the requirements. 9, General Test, the encapsulated PCB printing line board or lamp rack is tested by special detection tools for electrical performance testing to distinguish between good and bad. 10, spare time, use the spanning machine to distinguish the brightness of different brightness as required, and pack them separately. 11. Enter the warehouse. After that, go out in batches and contribute to the people The above is the answer to how to produce LED lamp beads for automatic LED lamp beads and related questions. I hope it will be useful to you [responsible editor: a dream] |
