SMT Reflow Soldering Instructions SMT

1.Reflow soldering should not be done more than two times.
2.When welding, the material is heated and can not press the surface of the colloid.

CAUTIONS

1，The encapsulated material of the LEDs is silicone ,so the surface of LED colloid is softer, forcing the colloid surface hard will affect the reliability of LED.

2，Material confirmation. Whether the LED Bin specifications of the material are consistent , such as whether VF, XY, brightness and so on belong to the same specification, the same specification should be used together, if not the same specification LED is applied to the same object, it should be evaluated first, (if different VF or XY cast together may produce difference in brightness or color).

3，Packaging and storage

3.1 Before opening packaging, avoid moisture entry into 1W 2835 LED SMD series LED is suggested to be stored in a drying cabinet with built-in desiccant. The storage environment is 5-30 centigrade, no more than 50% humidity. If storage time is over 3 months, 1W 2835LED needs to be re dehumidifying (65 degrees centigrade for more than /24 hours).

3.2 Open the precautions after packing. LED is a surface mount. When the 1W 2835 LED is welded, the internal separation of LED may occur. The luminescence efficiency is affected and the luminance decreases or the color variation.

A，After opening the package, welding should be completed as soon as possible (within 12 hours).

B，The remaining materials are sealed or placed in an environment of 5~40 C and no more than 30% humidity.

C，If the open package is more than 24 hours (< 168 hours) or the humidity card is changed from blue to pink, 1W 2835 LED needs to be dehumidifying again (65 degrees centigrade for more than /24 hours). If the package is opened for more than 168 hours, it is necessary to dismantle the tape and remove the moisture at 150℃ /2h.

3.3，LED electrode and bracket are made of silver plated copper alloy. The silver layer on the surface is easy to be affected by corrosive gases. Please avoid contacting with corrosive environment to cause 1W 2835 LED discoloration, so as to avoid the poor weldability of 1W 2835 LED and influence the photoelectric performance. Avoid sudden changes in temperature and humidity of the environment, especially under high humidity environment, easy to produce water vapor condensation.

4，Electrostatic protection. 1W 2835 LED is a chip sensitive electronic component. Various measures should be taken to avoid static electricity, such as wearing an electrostatic bracelet or anti-static gloves during use. All devices, equipment and instruments should be well grounded.
