La description
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.
Available scope: high power LED in oil field, mine, petrochemical,
railway, and special forces, stage decoration industry, urban
landscape lighting, display and sports venues, special work of
lamps and has a broad prospect of application
