A and LED lamp using the attention matters

1, welding conditions: (solder joints from resin root 2mm above)

] dip: Please in 260 DEG C, 5 seconds welding completed 1, while avoiding resin immersion tin bath is required.

: 30W - iron iron, the tip temperature is not higher than 350 DEG C, welding in 5 seconds 1 times to complete. Do not apply the external force to the product when the

is welded. Attention to avoid the LED pin to suffer from corrosion or discoloration, otherwise it will cause welding difficulties, it is recommended to use as soon as possible.

2, notice:

] pin forming must be completed before welding, the distance between the mounting hole of the circuit board, please keep consistent with the electrode pins.

product lead frame will produce the bad in the condition of high temperature, please pin cutting at room temperature.

in the welding temperature returned to normal before, must avoid any vibration or external LED.

3, electrostatic protection

high brightness blue, green and white product is sensitive to static electricity, in use need to pay attention to the electrostatic surge will damage or destroy the product and in contact with the product table please grounded through a resistance of the conductive pad; soldering iron tip must be connected to ground recommend using a ion generator.

4,

cleaning when using chemical cleaning colloid must careful, because some chemicals on the colloid surface damage and cause fading such as trichloroethylene, acetone. Ethanol can be used to wipe, dip, time at room temperature is not more than 3 minutes.

b, chip LED attention matters

1, welding conditions:

] reflow: Please in 150 DEG C, 2 minutes within preheating, heating in 240 DEG C, 5S is welded at one time.

] soldering iron: with the highest 25W controllable temperature soldering iron, the tip temperature is not higher than 320 DEG C, in 3 seconds or less welding completed 1. Do not apply the external force to the product when the

is welded. Do not bend the line after the completion of welding.

2, packaging:

] due to the resin absorption of moisture in the welding caused by moisture evaporation and expansion may cause interfacial delamination, so the moisture-proof packaging is to ensure the lowest moisture in the bag.

product should be self packaging, play a year used in, bag packaging unopened before, in temperature of 5 to 30 DEG C, relative humidity & lt; 60% in storage.

] packaging bag after unpacking, the product must be in within 24 hours of welding after use, otherwise the product must be in the temperature of 5 to 30 DEG C, relative humidity & lt; 30% of ambient storage and the time is not more than a week; if not the products, please back moisture barrier bag sealed to preserve

] if the product beyond the requirements for storage or damp, it must be in the 60± under the condition of 5 DEG C bake for 12 hours.

Product on the surface of the electrode is gold-plated, vulnerable to corrosion or discoloration caused by welding, recommendations as soon as possible in a timely manner.

- note speed change and avoid the environmental temperature, especially in humid environment.

3, electrostatic protection

high brightness blue, green and white product is sensitive to static electricity, in use need to pay attention to the electrostatic surge will damage or destroy the product and in contact with the product table please grounded through a resistance of the conductive pad; soldering iron tip must be connected to ground recommend using a ion generator.
