5mm water clear straw leds

الوصف

A. LED packaging technology is introduced
1. Enlarge crystal: the lined the bunches of chip to get open a solid crystal. 2. Solid crystal: in the bottom bracket point conductive/don't conductive glue (conductive or not depending on the chip and type PN junction around or type PN junction and decide) and then have the chips into stents inside. 3. Short roast: let the glue solidified welding line chips don't move. 4. Welding line: in gold thread have the chips and stents conduction. 5. Former measure: preliminary test can not bright. 6. Encapsulating compound: use glue the chip and stents wrap up. 7. Long roast: let the glue solidified. 8. Measured after: test can light or not and electrical parameters are the standards. 9. The color and color spectrometer voltage roughly consistent product points out. *0. Packaging.

2. LED welding technology requirements and operation caution
1, production must wear anti-static gloves, anti-static wrist, DianLaoTie must grounding, forbidden unarmed touch of white LED two lead foot. Because of the white LED anti-static for **0 V, and on the job to *0% moisture**0% of the human body will damage when static light emitting diodes crystallization layer, work for a long time (such as *0 hours) diodes will failure (not bright), serious failure will immediately. 2, the welding temperature of **0 ℃, 3 seconds. The temperature too high, time is too long will blow out chip. In order to better protect LED, LED the colloid and PC board should keep 2 mm above the spacing, in order to make welding heat emitted except in pin. 3, LED the normal work of the current to *0 mA, the voltage of the slight fluctuations (such as 0.1 V) will cause the current wide fluctuations (*0% *5%). Therefore, in circuit design should be based on the pressure drop LED matching different limited flow resistance, to ensure that LED in the best working state. Too much electricity, LED can shorten your life, too little electricity doesn't make the light intensity. General in batch when supply LED spectral color separation, namely the same product in the bag of LED light strong, voltage, light color are yes, and in the spectral color table indicate.
