Frequently asked questions (FAQ)

LED lamp bead in the process of using the matters needing attention - (AddTime : 2013-01-26)

A, LED LAMP use the matters needing attention
1, welding condition: (solder joints should be from resin root 2 mm above) Should dip soldering: please in 260 ℃, within 5 seconds welding one completed, at the same time avoid resin immersion tin bath. Iron pieces: 30 w iron, its tip temperature is not higher than 350 ℃, in less than 5 seconds welding one complete. Welding do the products applied forces. Pay attention to avoid led pin suffered corrosion or discoloration, otherwise you will cause welding difficulties, it is suggested that in time as soon as possible to use.

2, use note:
Should pin forming must be finished before welding, circuit board on the mounting hole distance between please and electrode pin consistent. Pieces products in high temperature condition for pin cutting will produce the bad, please at room temperature for pin cutting. Pieces in the welding temperature back to normal before, must avoid make LED by any vibration or external forces.

3, electrostatic protection
High light blue, green and white product is to electrostatic sensitive, using on need to pay attention to electrostatic surge can damage or destroy products, and products of the table please contact with conductive table mat through the resistance grounding; The tip of the soldering iron must be ground; Recommend using ion generator.

4, cleaning
When using chemical cleaning gel should be especially careful, because some chemicals to colloid surface damage and cause a fade as trichloroethylene, acetone, etc. Ethanol can be used to wipe, dip, time in normal temperature not more than 3 minutes.

B, CHIP 200W led Flood light to use the matters needing attention

1, welding conditions: Pieces reflow soldering: please in 150 ℃, 2 minutes less than preheating, after heating in 240 ℃, 5 s in one welding.

Pieces welding welding: with the top 25 w controlled temperature soldering iron, its tip temperature is not higher than 320 ℃, in less than 3 seconds welding one complete. Welding do the products applied forces. After welding is complete don't bend line edition.

2, packing: Due to the moisture absorption resin pieces in welding caused water evaporation and inflation, may cause interface stripping, so moistureproof purpose of packing is to ensure that the bags inside the moisture minimum.
Products in the packaging should be within one year as of the use, not opened bags before, should be in temperature 5 ~ 30 ℃, relative humidity < 60% of the environment storage.

Pieces bags once opened, the product must be within 24 hours after welding use, otherwise the product must be in temperature 5 ~ 30 ℃, relative humidity < 30% of the environment and storage time is not longer than a week; If there is a need not products, please put back moisture bag seal preservation

If the above products should beyond storage requirements or sweat, the must in the ± 5 ℃ condition baking 12 hours.

Should the electrode surface, and the product is plated with gold, vulnerable to corrosion or discoloration caused by welding difficulties, it is suggested that in time as soon as possible to use.

Should pay attention to avoid environmental temperature fast degree changes, especially in the moist environment.

3, electrostatic protection
High light blue, green and white product is to electrostatic sensitive, using on need to pay attention to electrostatic surge can damage or destroy products, and products of the table please contact with conductive table mat through the resistance grounding; The tip of the soldering iron must be ground; Recommend using ion generator.
