In-line LED lamp beads, also known as plug-in light-emitting diodes, are an energy-saving and environmentally friendly lighting material for visible light, and a solid-state semiconductor device that can convert electrical energy into visible light. The light-emitting principle of LED is to pass the current through the compound semiconductor, and through the combination of electrons and holes, the excess energy will be released in the form of light to achieve the effect of light-emitting. Light-emitting diodes for visible light have a wavelength of 400 - 700 nm.

Precautions for the use of in-line LED lamp beads:

1. Welding prerequisites: (The solder joint should be more than 2mm away from the resin root)

Dip soldering: Please complete the soldering once within 5 seconds at 260°C, and prevent the resin from immersing in the tin bath.

Soldering iron: Use a 30W soldering iron, whose tip temperature is not higher than 350°C, and complete the soldering once within 5 seconds.

Do not apply external force to the product during welding. Pay attention to prevent the LED pins from being corroded or discolored, otherwise it will cause welding difficulties. It is recommended to use it as soon as possible.

2. Notes on use:

The pin formation should be completed before soldering, and the spacing between the device holes on the circuit board should be consistent with the electrode pins.

The product will be defective when the product is cut at high temperature. Please cut the lead at room temperature.

Before the soldering temperature returns to normal, it is necessary to prevent the LED from being subjected to any vibration or external force.

3. Static electricity protection:

High-brightness blue, green and white products are sensitive to static electricity. In use, it is necessary to pay attention to electrostatic surges that will damage or destroy the product. Please use a conductive pad to ground the workbench that is in contact with the product through resistance; the tip of the soldering iron must be To be grounded; an ion generator is recommended.

4. Cleaning:

Special care should be taken when cleaning the colloid with chemicals, because some chemicals can damage the surface of the colloid and cause fading, such as trichloroethylene, acetone, etc. It can be wiped and impregnated with ethanol, and the time should not exceed 3 minutes at room temperature.
