2835 positive white lamp bead supplier 2835 SMD lamp bead manufacturer Hailongxing Optoelectronics
There are many suppliers of 2835 white lamp beads, but what is the most concerned about in purchasing? Reliable source manufacturers, then the question comes back, what kind of LED light source manufacturers are reliable? Manufacturers who are professional, dedicated, and serve customers with heart are reliable. What kind of manufacturers are there? In fact, there are many, such as Hailongxing Optoelectronics, a manufacturer of 2835 SMD lamp beads. There are other big brands like Philips. These are all accumulated over time. Having experienced ups and downs for decades, we have consistently focused on the LED industry. Hilongxing Optoelectronics is professional because of its focus. Because imported products are expensive after all, and there are also problems in after-sales, so customers are more willing to find local LED lamp bead manufacturers who have accumulated experience in the industry.
So when someone asks me to recommend a reliable local manufacturer, I will recommend Hilong Optoelectronics without hesitation. Why? Because of the old brand of Hilongxing Optoelectronics, it has been deeply involved in the LED lamp bead industry for more than ten years.
It is not accidental that he has 4,000 old customers. All of this is the result of Hilongxing Optoelectronics' 17 years of intensive cultivation of the LED industry.
We have been paying attention to the procurement and strict control of raw materials. In order to effectively manage the quality of raw materials, our company has conducted corresponding qualification investigations on all raw material suppliers, and at the same time strictly follows the following procedures and standards to effectively control the introduction and management of suppliers: 1 . Newly added supplier admission process - "Procedures for Externally Provided Products, Services and Processes" - HLX/QP-13 2. Qualified supplier filing - "Qualified Supplier List" - HLX/QR-CG-02 3. Signing Quality Agreement - "Supplier Purchase Quality Agreement" 4. Raw Material Traceability - "Order Contract" - HLX/QR-CG-08 5. Supplier Assessment - "Supplier Assessment Scoring Form" -HLX/QI-CG-04 6 . Supplier Periodic Review - "Supplier Periodic Evaluation Standards" - HLX/QI-CG-02 7. Supplier Corrective Actions - "Non-Conforming Product Management Procedures" - HLX/QP-17 All raw material suppliers are required to Provide relevant certifications for materials, such as ROHS, and update them regularly. Pass these for quality assurance.

There are many welding methods for LED lamp beads on the chip, and the following is one of the commonly used methods for reference. First, use an electric soldering iron to heat some soldering tin on the positive and negative electrode pads of the lamp bead (the soldering tin must not be too much, otherwise, the positive and negative electrode pads will be connected once heated with a hot-air gun), then use a hot-air gun to heat the positive and negative electrode pads at the same time, after the tin melts, use tweezers to place the positive and negative electrodes of the lamp bead on the corresponding pad.
LED is the light emitting diode, which is a semiconductor solid light emitting device that converts electric energy into light energy. Its core is the PN junction. In addition to the forward conduction, reverse cut-off and breakdown characteristics of the general PN junction, it also has the light emitting characteristics under certain conditions. Its structure mainly includes the following parts: lead, bracket, encapsulation glue, bonding wire, LED chip, solid crystal glue and phosphor. The discoloration failure of LED lamp bead is closely related to its material, structure, packaging process and service conditions. The following will analyze the causes of its discoloration through specific cases.
LED lamp beads are also called light emitting diodes. It has a wide range of applications. Its luminous colors include red light, emerald green light, yellow green light, yellow light, purple light, blue light, white light and orange light. The above is monochromatic light. It can also be made into two or three colors.
The gold wire used to package LED lamp beads contains more than 99.99% gold. It is produced by drawing gold from this material. In addition to 99.99% gold, this gold also contains less than 1% other trace elements. One of the core components of LED lamp bead packaging is gold wire, which is the bridge connecting the luminous chip and the welding point, and plays a decisive role in the service life of LED lamp bead. So how to identify the purity of gold thread?
