257 square LED lamp beads, this lamp bead is packaged with high-definition environmentally friendly silica gel and wafer chips. Appearance The colloid is generally colorless and transparent, with a luminous viewing angle of 120° and a size of 2.0*5.0*7.0mm. White, red, yellow, green, orange, blue, purple, pink and other colors can be customized. Welding at 260 degrees and within 10 seconds, 257 square LED lamp beads are used in various home appliances, digital, communications, automotive electronics, medical beauty equipment, electronic teaching equipment, urban lighting, lighting, electronic toys, electronic clocks, traffic signs, etc. etc. can be applied.

The chip is the key factor that determines the quality of the lamp bead, so Hongfucheng Optoelectronics only chooses chips from big brands such as Taiwan Jingyuan and Sanan. We also use high-definition environmentally friendly high-temperature resistant epoxy resin glue to avoid deformation and cracking, and measure the program to ensure accuracy and density. In order to improve production efficiency, Hongfucheng also has a number of imported MST automatic wire bonding machines and die bonding machines, and the welding technology and precision have reached the high level of the same industry. At the same time, imported high-precision packaging equipment is introduced to ensure the stability and consistency of products in various production processes and reduce product defect rates. It can also conduct relevant performance tests according to the customer's product use environment, such as: light decay test, high temperature aging test, high voltage antistatic test, etc.

Storage conditions of 257 square LED lamp beads: the temperature is controlled at 10℃-26℃, the humidity is 40%-65%, and the electrostatic bag is sealed and stored. We need to wear gloves or finger cots when checking 257 in-line LED lamp beads, the work surface should also be grounded, and the electrostatic bag should be sealed in time after opening to prevent oxidation of the feet. Inspectors check whether the electrostatic ring is normal every day, and pay attention to whether the metal of the electrostatic ring is in close contact with human skin. There are four methods for the two-legged 257LED lamp beads: manual welding, automatic spot welding, soldering through tin furnace, and wave furnace welding. As the current increases and the temperature increases, its service life will decrease in a certain curve. The use environment of LED lights: the humidity is between 50%-80%, otherwise there will be electrostatic breakdown and high current kill, the temperature is -20 ℃ to 70 ℃.

In reflow soldering, the material is usually soldered no more than 2 times. When soldering by hand, the temperature of the soldering iron should not be higher than 350℃, and the soldering time of each solder leg should not exceed 3 seconds. 257 square LED lamp beads, it is recommended to use an anti-static wrist strap or anti-static gloves. All installations, equipment and machines of Hongfucheng Optoelectronics should be grounded and packaged with moisture-proof. SMD products are all vacuum-packed. If customers find any products with air leakage before use, they are prohibited from using them. The company adheres to the business tenet of "pioneering and enterprising, seeking common development, honesty and pragmatism, and focusing on specialization", relying on strong technical force to continuously carry out technological reform and innovation; using a sound quality management system to fully meet customer needs.
