The Application Notes

When using the SIP LED light source, Need 5-10g/W of heat sink aluminum so as to ensure the full heat.
Coated with a layer of uniform thermal grease between SIP-LED and aluminum. Please obey the following operation method to protect the SIP LED light source.

Clean
Use cotton swabs dipped in a small amount of alcohol cleaning, do not use the unknown chemical liquid cleaning SIP LED, because it may damage the SIP LED.

Welding operation
a. Ceramic substrate fast heat dissipation, difficult welding, welding time should not exceed 10 seconds, otherwise easily cause fall off the pad.
b. The use of larger power iron 80-120W, temperature maintained at around 380, the heat transfer faster flat or elliptic iron head.
c. The use of 0.8mm quality low residue tin line, first in the welded line ends with tind.The iron head contact ceramic substrate, solder joints are to be melted and immersion component lead after the head, the electric iron head along the welding pin gently into a left joint. Welding time is about 3-5 seconds, a sine wave shape of solder joints, surface should be bright smooth, not weld thorn, moderate amount of tin welding, pay attention to iron cannot come into contact with the silicone.

Electrostatic discharge and impulse current
a. Electrostatic discharge (ESD) or pulse current (EOS), may damage the SIP LED.
b. Must wear ESD wrist, ESD shoes or electrostatic gloves, can SIP LED production.
