Production workers must wear anti-static gloves, anti-static wrist, electric iron must be grounded, non unarmed touch white LED two lead foot. Anti-static because the white LED 100V, workbench Operating Humidity 60% -90% of the body's electrostatic damage to the crystalline layer of light-emitting diodes, diode work after a period of time (such as 10 hours) will fail (not lit). Severe will immediately be invalidated.
Soldering temperature of 260 ℃, 3 seconds. Temperature is too high, too long will burn the chip. In order to better protect the LED, the LED Colloid and PC board should keep more than 2 mm spacing, so that the welding(Welding Electrode) heat dissipated in the pin.
3.LED normal operating current of 20mA, slight fluctuations of voltage (0.1V) will cause substantial fluctuations in current (10% -15%). Therefore, pairing different limiting resistor in the circuit design should be based on the voltage drop of the LED to LED in top working condition. Current LED will shorten the life of, the current is too small, reach the desired light intensity. I company will bulk supply the LED spectrophotocolorimeter, and that same package of LED light intensity, voltage, light colors are consistent and indicate spectral color table.
(1) soldering iron: the tip of the soldering iron (up to 30W) temperature does not exceed 300 ℃; welding time is not more than 3 seconds; welding position of at least 2 mm from the gel.
(2) Wave Soldering: the highest dip soldering temperature of 260 ° C; the dip soldering takes less than 5 seconds; dip soldering position of at least 2 mm from the gel.

LED welding curve pin forming method:
(1) must be 2 mm from the gel to bend bracket.
(2) The stent fixture or done by professionals.
(3) The stent must be completed before welding(Welding Consumables).
(4) stent is the need to ensure the pin and spacing consistent with the circuit board.

Wash
When chemical cleaning colloidal must be especially careful, because some chemicals on the colloid surface damage and cause discoloration such as trichlorethylene, acetone. Available ethanol wipe, dipping time of not more than three minutes at room temperature.
The electrostatic protection electrostatic and the sharp rise of the current will damage the LED InGaN products use anti-static devices, such as protective belt and gloves.
