Chip stripping method of LED lamp beads

Abstract

The invention relates to a chip stripping method of LED lamp beads. The method comprises the steps of: a) shearing the upper end of LED lamp beads to allow a distance between the sheared region and achip to be 0.25-0.5mm; b) welding and fixing the N sheared lamp beads on a LED support strip in a linear direction, wherein the heights of the lamp beads after welding are consistent; c) putting the LED support strip into an oven for baking to heat and soften the lamp beads; and d) putting the baked LED lamp beads into a culture dish for immersion by employing an organic solvent, wherein the glueat the surfaces of the chips in the LED lamp beads are dissolved by the organic solvent, and the chips are stripped off from the lamp beads, and the stripped chips are taken out from the culture dishby employing tweezers. The time of stripping of the LED lamp bead chips is reduced, an ordinary organic solvent is only used to prevent the chips from being damaged by lamp bead corrosive liquid so asto improve the stripping efficiency of the lamp bead chips, reduce the use of the lamp bead corrosive liquid, reduce the damaging to the personnel, the environment and LED chips caused by the lamp bead corrosive liquid and improve the analysis efficiency of the poor LED lamp beads.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a chip peeling method of an LED lamp bead. Background technique [0002] LED is a new light source for lighting in the 21st century. Under the same brightness, the power consumption of semiconductor lamps is only 1 / 10 of that of ordinary incandescent lamps, but the life span can be extended by 100 times. The LED device is a cold light source with high luminous efficiency, low working voltage, low power consumption, small size, flat packaging, easy to develop thin and light products, strong structure and long life. The light source itself does not contain harmful substances such as mercury and lead. No infrared and ultraviolet pollution, no pollution to the outside world during production and use. Therefore, semiconductor lamps have the characteristics of energy saving, environmental protection, and long life. Just like transistors replace electronic tubes, semiconductor ...

At this stage, the chip stripping of LED lamp beads is the method of soaking lamp bead corrosive liquid. Excessive use of lamp bead corrosive liquid has a greater impact on the environment, and the length of soaking time also plays a greater role in the analysis of practical problems. How to quickly and effectively realize the chip stripping of LED lamp beads has become the reverse of the main research at this stage.
