Guangmai Technology is proffesional in making the 6868 6565 UV UVA SMD LED Chip 370nm 380nm 390nm 400nm.
Precautions when solder the 6868 uv smd leds onto pcb boards:
Product dehumidification
Since SMD products absorb moisture and will cause vapor evaporation and expansion during high-temperature soldering, it is easy to cause peeling and break the gold wire connecting the chip and the bracket. Therefore, customers should unpack and bake at 65-70 degrees for more than 12 hours before use. After opening the package, the welding should be completed in a short time, not more than 24 hours, if more than 24 hours, you need to dehumidify again. (Reel baking: 65-70 degrees/10-15H, bulk baking: 130-150 degrees/2-3H) SMT patch: Customers need to choose a light-emitting surface larger than SMD (colloid) when SMT placement The suction nozzle can prevent the improper setting of the nozzle pressure height from damaging the inner gold wire of the lamp bead. The pressure height of the suction nozzle during SMT will also affect the quality of the lamp bead. The pressure of the suction nozzle is too deep, which will oppress the lamp bead gel internally. The deformation or breakage of the gold wire causes the lamp beads to not shine or flicker and quality problems. Choosing the right nozzle is the key to providing product quality.
Manual welding
It is recommended to use thermostatic iron and select (05MM tin wire, keep the temperature within degrees, and the soldering time of a single lamp bead should not exceed 3 seconds. During the soldering process, the glue should not be pressed against the surface of the glue at high temperature, and no pressure can be applied to the LED pins. , Let the tin wire naturally melt and combine with the pins. Be careful not to use hard objects and sharp-edged objects to scratch the surface of the glue, which will easily cause the direct internal gold wire to deform and cause dead lights. (GMKJ LED recommends that mass production cannot be soldered by hand, because (The quality of manual welding is unstable)
Reflow soldering
Mass production needs to use SMT patch production. Geyangguang recommends that the melting point of solder paste is below 220 degrees, and it is better to use reflow soldering in eight temperature zones. The high temperature cannot exceed 240 degrees, and the peak time is less than 10S. Reflow soldering needs to be completed in one time. Lamp beads must not be reflow soldered more than twice. Multiple reflow soldering is destructive to LED products. After reflow soldering the beads should not be repaired. When repairing is unavoidable, you must use a heating platform or a soldering expert to perform the operation, but it must Confirm in advance that this method will or will not damage the characteristics of the LED lamp beads. If you don't understand during the production process, you can contact the corresponding salesperson of Shenzhen Guangmai Technology Co., Ltd. for consultation and solution at any time.
