  • Patent number: 10593850
    Abstract: A method for manufacturing a light emitting diode package comprises: arranging a first solder and a second solder between a substrate and a light emitting diode; and subjecting the first solder and the second solder to heat treatment to bond the substrate and the light emitting diode. The heat treatment comprises: increasing the temperature of the first and second solders from room temperature to a temperature Tp; maintaining the temperature Tp; and lowering the temperature Tp. The heating step comprises: a first ramping step of increasing a temperature from room temperature to a temperature TA at a constant speed; a pre-heating step of increasing the temperature from the temperature TA to a temperature TB to impart fluidity to the first and second solders; and a second ramping step of increasing the temperature from the TB to TL at a constant speed.
