Background technology
Eutectic refers to the phenomenon of the fusion of eutectic solder generation eutectic thing at relatively low temperature, and eutectic alloy directly changes to liquid state from solid-state, and without the plastic stage, is that a liquid state generates two solid-state balanced reactions simultaneously.
Large-power light-emitting diodes has the advantages such as light efficiency is high, volume is little, the life-span is long, energy-conserving and environment-protective, has become the main development direction of following lighting engineering.In high power illumination LED encapsulation procedure, head resits an exam and considers the radiating requirements of light fixture, wherein attracts attention with the radiating requirements of die bond layer again.
The die bond processing procedure mode that current domestic encapsulation factory commonly uses is elargol die bond processing procedure or AuSn eutectic die bond processing procedure, but due to the too high heat radiation bottleneck that the problem such as not good produces with reliability of elargol thermal resistance (>3.0 DEG C/W), high-capacity LED illumination application demand cannot be met, and though AuSn eutectic die bond can solve heat dissipation problem, but easily cause because die bond temperature (>310 DEG C) is too high that chip is impaired to be reduced with luminous efficiency, and the problem such as substrate limited (inapplicable lead frame), therefore active demand has low thermal resistance (<2.0 DEG C/W) concurrently, high temperature tolerance (>250 DEG C), low junction temperature (<180 DEG C), the die bond process technique of high-reliability.
Covering brilliant tin cream sealing packing technique characteristic is shorten LED processing procedure in the time of high-temperature baking, can lower material thermal stress; Add that the heat that chip produces conducts on substrate via large area tin cream, therefore heat-conducting effect is good; And processing procedure simplifies, yield is easy to management and control.
