The invention relates to a three-section LED lamp flip-chip production process. The production process comprises the following steps that three power wires are inserted into a driving plate through anoperator; the three power wires are fixed to the driving plate through wave soldering; the three power wires are a middle wire, an edge hole line and an edge line correspondingly; the driving plate is aligned and inserted with a clamping groove in a lamp cup; a three-section type lamp holder is pressed; the three-section type lamp holder is fixed; a middle through hole of the three-section type lamp holder and the middle wire on the driving plate are welded and fixed through a constant-temperature electric soldering iron; then a edge through hole of the three-section type lamp holder and theedge hole line on the driving plate are welded and fixed; and the lamp cup and the driving plate component which are welded are sent into a lamp holder riveting machine to be riveted. According to thethree-section LED lamp flip-chip production process, due to the fact that the flip-chip process is adopted, the driving plate is arranged in the lamp cup firstly, and then the three-section type lampholder is arranged, so that the three-section type lamp holder can be fixed through the lamp cup, the difficulty of the process of welding the lamp cap is reduced, and the whole production process can work on the assembly line, the working efficiency is greatly improved, and the production cost is reduced.
