Guangmai Technology is professional in making the 1W Epistar Chip SMD LED 3030 Package 3V 6VDC Input.
About Epistar chips questions:
1. What are the main products of Epistar?
Answer: There are blue light, white light (blue light chip to white light), red light, yellow light, green light chip.
2. Can Epistar 45mil chips achieve 3W?
Answer: BXCA4545XXX-D can achieve 3W, 160-200LM. At the same time, the customer's package heat dissipation must be handled well, and the end customer's heat dissipation must also be handled well.
3. What kind of phosphor will have a better luminous effect on Epistar chips?
Answer: It is recommended that different wavelength bands be equipped with different phosphors to achieve the best luminous effect.
4. How many volts can the ESD protection of Epistar chips reach?
Answer: Epistar chip's ESD protection can reach 3000V
5. Epistar's chip has strong anti-static ability. Is it possible to not add a Zener tube?
Answer: Depending on the specific application, it is recommended to use LEDs for outdoor lighting such as street lights; for flashlights, spotlights and other applications, you can consider not adding a Zener tube to save costs.
6. What are the specific advantages of Epistar chips compared with other chips?
a. The stability of the product is high, because it is a double electric shock structure, and there are 6 layers of protective film on the surface, it is easier for customers to operate during the production process, the product yield rate is better controlled, and the light decay is small;
b. ESD protection can reach 3000V, while similar products are around 500V. Some less demanding applications can help customers save the Zener tube to save customers' costs;
c. When making polycrystalline LEDs, our advantage is very obvious. Customers can connect in series and parallel at will according to their own requirements.
7. How many bins does Epistar ship? How many bins can be produced at least?
Answer: A small batch of trial production can produce one bin, 10k-50k is at least 2 bins connected, and more than 100k, 2 bins are required. The bin area can be controlled when sending samples to ensure subsequent shipments.
8. Are there any patents for Epistar's chips? If there are patents, how to guarantee the customers?
Answer: Epistar chips have more than 60 patents, which can guarantee patent rights including Japan, but customers should pay attention to the patent authorization of phosphors, otherwise even if the chip has a patent, the product will not be guaranteed. As for the guarantee, the customer has special requirements, and if the quantity is large, it can also provide a certificate such as a patent guarantee to the customer.
9. What should be paid attention to when soldering wafer chips?
a. Before using the wafer chip, be sure to read the technical information of the chip carefully. It is not possible to completely use the welding process of other brands to weld the wafer chip.
b. The wafer chip is a horizontal double electrode. The size of the N pole guide post is 105-110um. When welding the N pole of the chip, pay attention to the wire bonding position must be accurate, and the deviation should not be too large, and the solder joints should not be too large. If the wire bonding position deviates too much or the solder joints are too large, it may cause the PN pole reverse leakage. If the reverse leakage exceeds the standard, the lumens (LM) of the LED will be reduced. PN pole reverse leakage should be less than 5uA.
