Guangmai Technology is professional in making the 5W 10W 15W 20W 5050 SMD LED Chip with ALN Eutectic Die Bonding.
What is the Eutectic Die Bonding/Eutectic welding for the LED chips???
Eutectic welding is an inevitable production link in microelectronic assembly, and it is one of the important production process steps.
Literally explained, it means using alloy (eutectic) soldering and packaging of LEDs.
In a relatively low temperature environment, two or more metals (such as gold, tin, gold and silver) are used to achieve the phenomenon of eutectic fusion, so that the eutectic is directly converted from solid to liquid without plastic treatment Phase is a reaction of equilibrium change in which a liquid sample generates two solid samples at the same time.
LED eutectic refers to the case where the LED adopts eutectic welding, the bottom of the crystal grain is coated with pure tin or gold-tin alloy as the contact surface, so that the crystal grain can be directly welded to the substrate plated with gold or silver. on.
In this way, when the substrate is heated to a suitable eutectic temperature, gold or silver elements penetrate into the gold-tin alloy layer to change the composition of the alloy layer, and finally increase its crystal grain melting point, so that the composition of the eutectic layer will change at the same time. The LED is firmly welded to the heat sink or substrate.
