COB strip light production process

The cob strip is a new type of high brightness, high brightness linear strip, its appearance is exquisite, the product color is highly consistent, the light is uniform, soft and bright, can achieve multi-grade waterproof, the use of flip-chip packaging process, there is good heat dissipation, low heat, long life and many other excellent features.

Craftsmanship, achievement of excellent quality, cob strip light production materials.

LED chip, solder paste, PCB circuit board, phosphor, silicone, terminal, backing, reel, flip-flop solid crystal machine, reflow soldering, dispensing machine, test instrument, soldering machine, mixer.

The process of making cob strip light.

1. first PCB pads through the automatic brush solder paste machine coated with good solder paste, the uniformity and thickness of the paste coating determines the quality and flatness of the welded west piece, as well as the good and bad of the welded chip.

2. Load the coated PCB board on the carrier, set the chip solidification program by computer programming, debug the direction and height of solidification, and confirm the electrode direction of the chip.

3. First do a small batch of curing test, the cured PCB will be inspected for appearance quality, to determine the direction of curing, whether there is even solder paste, the correct position of curing, the inspected products into the next process.

4. Put the solid crystal PCB board and wafer into reflow soldering, set the reflow temperature and speed, solder the LED chip firmly in reflow soldering, and conduct electrical test after the oven to test whether the LED chip is normal light

5. After testing the LED chip on the PCB board, carry out the silica gel and phosphor with powder process, according to the customer specified color temperature, brightness and other photoelectric parameters, different ratios of the configuration, the glue will be matched to the positive air off the bubble

6. Fix the PCB board on the dispensing machine carrier for the dispensing process, the dispensing process is the most critical process for the success of the strip light, after dispensing the PCB board into the oven for baking

7. Bake the strip after dispensing to test the photoelectric parameters and see if the test data meet the customer's requirements.

8. After soldering the 0.5m PCB board, connect it into 5-10m, back glue and pack the strip with reel.

9. Through the small batch test production without abnormalities and then turn to mass production

The overall process of cob strip production is more complicated, each step is related to the quality of the strip, need to be rigorous in every step to ensure quality finished products.

As a new linear lighting products, cob strip compared to traditional linear lighting products cost and no absolute advantage, with the subsequent process continues to mature, as well as the gradual completion of the industrial chain, cob strip will shine.

The excellent production process of cob strip light, its product color is highly consistent, luminous into linear, drip wrapped lamp beads can achieve a richer color.
