Characteristics of American Puri Chip

Hello, landlord! The characteristics are as follows: 1. What are the main products of Puri? A: There are blue chips, white chips (blue chips turn white) and green chips. 2. How many lumens can Puri's chip reach? A: Rip's BXCA4545XXX-D can achieve 85-95LM/350mA. BXCB4545XXX-E was launched in 2009, and it is guaranteed to be above 100LM/350MA. 3. Can Rip's 45mil chip achieve 3W? A: BXCA4545XXX-D can achieve 3W, 140- 160LM, and at the same time, it is required that the heat dissipation of customers' packages should be handled well, as well as that of end customers. 4. What kind of phosphor is used for Puri's chip to make it glow better? A: It is suggested to use different phosphors in different bands to achieve the best luminous effect. 5. How many volts can the ESD protection of Puri chip reach? A: The ESD protection of Puri chip can reach 3000V, while products such as Corey and Xu Ming can only achieve 500 V.6. Puri chip has strong antistatic ability, so can Gazzina tube be omitted? A: Depending on the specific application, it is recommended to use LED as outdoor lamps such as street lamps. If it is used in flashlight, spotlight and other applications, Gazzina tube can be considered to save costs. 7. What are the specific advantages of Puri chip compared with other chips? A, the product has high stability. Because of the double electric shock structure, there are 6 layers of protective films on the surface, which is more convenient for customers to operate in the production process, the product yield is better controlled, and the light attenuation is smaller; B, ESD protection can reach 3000V, while similar products are about 500 V. Some applications with low requirements can help customers save zener tubes to save customers' costs; C, when making polycrystalline LEDs, our advantages are very obvious. Customers can connect in series and in parallel at will according to their own requirements. 8. How many boxes does 8.Puri deliver? How many boxes can you give at least? Answer: A small batch of trial production can produce one cabinet, and at least two cabinets are connected. More than 100 K, 3-4 cabinets are needed. The area of each cabinet can be well controlled during sample delivery to ensure subsequent shipment. 9. Is Puri's chip patented? If there is a patent, how to guarantee it to the customer? A: Puri's chips have more than 60 patents, which can guarantee patents including Japan, but customers should pay attention to the patent authorization of phosphor itself, otherwise even if the chips are patented, the products cannot be guaranteed. As for the guarantee, customers have special requirements, and if the quantity is large, they can also provide customers with certificates such as patent guarantee. 10. What should I pay attention to when soldering Puri chips? A, before using Puri chip, be sure to read the technical data of the chip carefully. You can't completely use other brands of welding technology such as Ke Rui or Xu Ming to weld Puri chips. B. The Puri chip is horizontal and has two electrodes, and the size of the N-pole guide post is 105- 1 10um. When soldering the N pole of the chip, pay attention to the accurate bonding position and don't deviate too much. If the wire bonding position deviates too much or the solder joint is too big, it may lead to reverse leakage of PN pole. If the reverse leakage exceeds the standard, the lumen value (LM) of LED will be reduced. The reverse leakage of PN pole should be less than 5uA. Hope to adopt! thank you
