4020 side phantom SK6812 programmable 5V quad pin WS2812B SMD led light beads built-in IC programmable

I. Protection against excessive current

Must be protected by a resistor, otherwise slight voltage shifts will result in large current changes (burnout will occur)

II. Storage

1. Before the product is not used, please do not open the product moisture-proof bag 2. Before unopened should be stored in the environment below 30 ℃, temperature below 60% 3. After opening the bag, the LEDs need to be stored in the conditions below 30 ℃ / 40% temperature, and must be used up within 7 days

4. If the moisture-absorbent material has disappeared or the light-emitting diode has exceeded the storage time, for thousands of treatment should be used 60 ℃ 5 ℃ 12 hours

Three welding conditions

1. PB-FERR reflow solder temperature profile

2. Reflow soldering should not be more than two times

3. Please do not press the LED light heavily when soldering

4. Do not distort the circuit board when the temperature does not fall back to room temperature after soldering. 4. When using manual soldering, the temperature of the soldering iron is not higher than 320 degrees, and the soldering time is not more than 3 seconds
