Welding method of LED lamp beads

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 beads change color? These six reasons are worth noting

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.

How to identify whether LED lamp beads are pure gold

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?

Practice tells you the difference between 365nm and 395nm purple light beads

It is believed that many people are familiar with the purple flashlight, and the functions of 365nm and 395nm lamp beads are different. To put it simply: The light emitted at 365nm basically contains no purple, which does not affect the judgment. The purple color at 395nm is very strong, which sometimes affects the judgment. The fluorescence at 365nm is generally much stronger than that at 395nm; The fluorescence effect at 395nm is weaker than that at 365nm. 365nm can emit some fluorescence that cannot be emitted at 395nm, such as the fluorescence on the back of people people coins

How much do you know about led beads

With the gradual development of LED lighting, LED has gradually replaced some traditional light source products in public places such as lighting engineering assistance. In 2009, LED began to popularize in developed countries. LED lamps have quickly become the new favorite of the market in the commercial application places where the electricity cost is high and the use time is long. As the use of LED lighting fixtures, LED market development is divided into several stages.
