During the production process, some lamp beads are encountered in the phenomenon that there is a phenomenon that there is a phenomenon of one, a string, and several string of lamp beads when testing. The welding method can be divided into electric iron welding, heating platform welding and reflux welding, etc.: A, the most common electric iron welding, such as samples and maintenance. Because most existing manufacturers are for saving costs, most of the purchased electric iron soldiers are mostly. Unqualified products are mostly poorly grounded, and there are leakage. This is equivalent to forming a loop formed by the leakage soldering iron tip-welding LED-human body-the earth, which means dozens of times- Hundreds of times the voltage that the lamp beaded was added to the LED lamp bead, and it instantly burned it out. Note: The situation of the static electric band will be more serious, because when the human body is connected to the electrostatic belt, the resistance to the ground is smaller, and the current from the human body to the lamp beads will be larger. There are still so many lamp beads damaged problems. B, the dead lamp caused by the heating platform welded. Due to the continuous lamp sample list, most companies in order to meet the needs of small batch and sample lists, due to the low cost of equipment, simple structure and operation, the heating platform has become the best production tool However, due to the use environment (for example: there is a problem that the temperature in the place with a fan) and the degree of practice and the control of welding operators and the control of welding speeds have become a major problem of dead lamps. In addition, heating Platform equipment grounding situation. C, reflux welding, generally this welding method is the most reliable production method, suitable for large quantities of production and processing. If the operation is improper, it will cause more severe dead lights, such as unreasonable temperature adjustment, poor machine grounding, etc. 2. Improper storage causes dead lamps: This kind of problem is the most common. Since the problem of moisture preventing the moisture -proof after the package is opened, the seal of the lamp beads mostly uses silicone materials. According to a certain water absorption characteristics, the lamp bead paste after the moisture is posted by the moisture bead paste. After the board, the silicone of the silicone after the high -temperature welding process will be hot and contracted. The golden thread, chip, and brackets will be deformed and the golden thread will be broken. The lighting point will be generated. In the environment, the storage temperature is -40 C- 100 C, and the relative humidity is below 85%; it is better to use LED within 3 months under its original packaging conditions to avoid rust of the bracket; when the LED packaging bag is opened, the packaging bag is opened. After, use it as soon as possible. At this time, the storage temperature is 5 -30 , and the relative humidity is below 60%. 3. Chemical cleaning: Do not use unknown chemical liquid to clean the LED, because that may damage the surface of the LED colloid and even cause collagen cracks. If necessary, please use alcohol -cotton swabs in room temperature and ventilation environment. Time is best controlled in one Windy wind is complete. 4, deformation causes dead lamps: Due to the deformation of some lamp plates, the operator will be plastic. Due to the deformation of the board, the lamp beads on it will also deform at the same time. There is this type of board for plastic surgery before production. Long -term production assembly and movement may also cause the phenomenon. There is also a stacking. In order to facilitate the convenience of the production process, the lamp board is stacked at will. Due to gravity, the lower lamp beads will be changed to the golden thread. 5. The heat dissipation structure, the power supply and the light board do not match: Due to the unreasonable power design or the selection of the power supply, the power supply exceeds the maximum limit (ultra -current, instant impact); Early light decline 6, factory grounding: must check whether the total ground line of the factory is good. 7, static electricity: static electricity can cause LED function to fail. It is recommended to prevent ESD from damaging LED. A, LED detection and assembly must bring anti -static bracelets and anti -static gloves. B. Welding equipment and testing equipment, working tables, storage racks, etc. must be well grounded. C. Use ion fan to eliminate static electricity generated by friction during storage and assembly during storage and assembly. D. The ingredient box with LED uses anti -static ingredients, and the packaging bag uses a static electric bag. E. Don't have a fluke, touch the LED. The abnormal phenomenon that will occur by the LED damaged by ESD is: A. Inverse leakage, the light will cause the brightness. B. The voltage value becomes smaller. LED cannot shine when low -current drivers. 8. Poor welding causes the lights to not light up.

UV LED curing is a process that uses ultraviolet (UV) light-emitting diodes (LEDs) to cure or dry adhesives, coatings, inks, and other materials. The process involves exposing the material to UV light, which causes a chemical reaction that results in the material hardening or curing. UV LED curing is a faster and more efficient process than traditional curing methods, such as thermal curing or air drying. It can be used in various industries, including electronics, automotive, and medical.

The UV light from LEDs is usually in the range of 365nm-385nm, it has a high intensity and it's very consistent, this allows for precise and consistent curing. It also allows for a more efficient process as it can cure in seconds, compared to minutes or hours for other curing methods. UV LED curing also does not generate heat, which can be beneficial in certain applications where heat can be a problem.

UV Curing Vs UV LED Curing. What Are The Key Differences?

UV curing typically uses a UV lamp or mercury vapor lamp to cure the materials, while UV LED curing uses UV light-emitting diodes (LEDs) to cure the materials. UV LED curing can cure in seconds, while UV curing can take minutes or hours to cure. UV LED curing is more energy efficient than UV curing because it uses less power to generate UV light.

UV LED curing uses light in the range of 365nm-385nm, allowing for consistent curing. UV curing uses a broad spectrum of light that can vary depending on the type of lamp used. UV LED curing is more environmentally friendly than UV curing because it does not produce harmful emissions.

Applications of UV LED Curing in The Field of Microelectronics

In the field of microelectronics, UV-LED curing glue is widely used for bonding and sealing microelectronic components, such as sensors, chips, and transistors. It is also used for the encapsulation of microelectronics components and for PCB assembly.

UV adhesives, also known as UV-curable adhesives or sealants, are a type of adhesive that is activated or cured through exposure to ultraviolet (UV) light. These adhesives can be made from a variety of different polymer resins, such as acrylate or epoxy. When exposed to UV light, the monomers in these resins react and polymerize, forming a strong bond.

UV sealants are different from traditional sealants, such as epoxies and cyanoacrylates, which require time to cure at room temperature or heat to cure. UV glues and sealants, however, cure almost instantly when exposed to UV light, which makes them ideal for high-speed, automated assembly processes.

Here are some ways UV LED curing is done via adhesives in the field of microelectronics.

Bonding and sealing

UV LED curing glue is used to bond and seal microelectronic components, providing a fast, efficient, and precise method of bonding and sealing. The UV light from the LEDs provides a quick curing process that eliminates the need for heat and pressure, which can damage sensitive electronic components. As a result, this gives us products that have a very low chance of being faulty.

Encapsulation

UV-LED curing glue is used to encapsulate microelectronic components to protect them from moisture, heat, and other environmental factors. The UV light from the LEDs provides a quick curing process, and the seal created is airtight, providing long-lasting protection. With the help of UV LED curing not only will the encapsulation be of high quality but will increase the safety of the final product.

PCB assembly

UV-LED curing glue is used in the PCB (Printed Circuit Board) assembly process, where it is used to bond the various components of a PCB together. Compared to traditional technology like UV glues and sealants, UV-LED curing glue is fast, efficient, and precise, and it helps to improve the performance and reliability of the PCB. Overall, UV LED curing sealants help build PCB boards way better than what previous products and competitors of UV LED curing offer.

Conductive Adhesive

UV-LED curing glue can also be used as a conductive adhesive, which helps to eliminate the need for soldering, which can damage the microelectronics components. UV LED curing glue gives you a substitute to traditional UV glues and sealants. It is different because here substrates never transmit in the wavelength of the UV. Moreover, what makes them an exceptional choice is due to their outstanding optical clarity.

Touch Screens

Manufacturers of touchscreen devices often tend to utilize UV LED curing adhesive before assembly. The most beneficial part is the low heat and on-demand curing that this substance offers through UV LED lamps. It helps prevent potential damage to sensitive components of a rather precious component of an electronic device by delivering a very consistent and instant result.
