How to use patch led lamp beads

Reflow welding, if it is aluminum substrate, can also use hot plate. The soldering iron heats the aluminum substrate, but pay attention to the speed and take it off immediately after welding.

Virtual welding is easy to occur, which is caused by the virtual welding of led chips on LED lamps and the failure to connect the gold wires in welding.

Open the steel mesh according to different styles of light bars, and the steel mesh can be consistent with the light bars. Choose a good solder paste.

Inferior solder paste is easy to fall off when using LED lamp beads. The solder paste is printed to the position to be soldered, and then soldered after reflow.

Light Emitting Diode(LED)

LED is the abbreviation of English light emitting diode. Its basic structure is an electroluminescent semiconductor chip, which is solidified on the bracket with silver glue or white glue, then the chip and the circuit board are connected with silver wire or gold wire, and then the periphery is sealed with epoxy resin to protect the internal core wire. Finally, the shell is installed to make the led lamps have good seismic performance.
