●Notes for reflow [if reflow products are needed]
1.Reflow soldering should not be done more than two times. In the case of more than 24 hours
passed soldering after first, LEDs will be damaged.
2.When welding, do not press hard on the colloid surface when the material is heated.
3.Scrape the heat-conducting solder paste on the aluminum base plate, stir the solder paste
clockwise for 10-15 minutes before scraping the solder paste, and place the aluminum base plate
on the solder paste scraping tool. Scrape the solder paste evenly and thickly
4.Scrape solder paste steel mesh needs to be made into a cross, so as to allow air circulation,
avoid solder paste lifting caused by LED poor heat dissipation
5.Note that the lamp should be installed flat and the two pins of the LED light source should be
installed on the welding pad position of the aluminum substrate.
6.Scrape the aluminum base plate of solder paste in 2 hours to install all the light source, light
source installed in the aluminum base plate, the operator should self-check whether the light
source is installed (can't have reverse, light source bottom suspension) to tilt 45 degrees Angle to
check each light source
7.After reflow welding, check whether the light source is in the position of the welding pad, and do
not have eccentric phenomenon, or the line will be broken in the second light distribution lens,
resulting in open circuit.
8.Rapid cooling is not allowed after reflow soldering.
9.Do not weld on deformed PCB.
●SolderingIron
1.When hand soldering, keep the temperature of iron below less 300℃ less than 3 seconds.
2.The hand solder should be done only one time.
●Repairing
Repair should not be done after the LEDs have been soldered. When repairing is unavoidable,a
double-head soldering iron should be used (as below figure). It should be confirmed in advance
whether the characteristics of LEDs will or will not be damaged by repairing.
●Cautions
1.LED packaging is silica gel, so the LED colloidal surface is soft, hard pressure on the colloidal
surface will affect the LED reliability, so there should be preventive measures to avoid the strong
pressure on the package parts, when the suction nozzle, the pressure on the colloidal surface
should be appropriate.
2.Components should not be mounted on warped (non coplanar) portion of PCB. After soldering,
do not warp the circuit board.
3.Do not apply mechanical force or excess vibration during the cooling process to normal
temperature after soldering. Do not rapidly cool device after soldering.
