SMT low-temperature manufacture procedure of LED light bar

Abstract

The invention discloses an SMT low-temperature manufacture procedure of an LED light bar. The SMT low-temperature manufacture procedure comprises the following steps that (1) low-temperature solder paste is pasted on an FPC board by adopting a metal stencil printing way; (2) LED light beads are accurately placed on the FPC board by an SMT mouter; and (3) the operating temperature of a reflow soldering machine is adjusted, so that the temperature zone of the reflow soldering machine is below 180 DEG C, and the low-temperature solder paste is heated by the reflow soldering machine until the low-temperature solder paste is melted so as to enable the LED light beads to be welded on the FPC board to manufacture the LED light bar. The SMT low-temperature manufacture procedure is concise in process, and high in working efficiency; the low-temperature solder paste is adopted ingeniously, and the temperature zone of the reflow soldering machine is controlled reasonably to be below 180 DEG C, so that the phenomenon that the LED light beads are damaged at high temperature is avoided, the quality of the LED light bar is effectively ensured, and the STM production process requirements are met; and besides, a PET material is adopted, so that the SMT low-temperature manufacture procedure is more favorable to be realized, the production efficiency is improved greatly, manpower and material resources are saved, the production cost is reduced, and the SMT low-temperature manufacture procedure is beneficial for wide popularization and application.

AI Technical Summary

Problems solved by technology

With the miniaturization of electronic products and the automation of the production process, the requirements for solder paste or flux are becoming more and more stringent or refined. For example, in the LED lighting industry, many electronic components cannot withstand high temperatures above 200°C. For this reason, Low-temperature electronic device assembly and welding can only be done manually, and the work efficiency is low
