    摘要: There is disclosed herein a method for laser soldering, comprising the steps of: (a) providing an electronic component 10 having at least two terminations thereon; a dielectric substrate 14 having a first surface 16 on a first side thereof, a second surface on a second side thereof, and at least two mounting pads 24 arranged on the first surface 16 in matched relation with the terminations of the electronic component 10; and a diode laser 50; (b) depositing solder paste atop the mounting pads 24; (c) placing the electronic component 10 atop the substrate 14 such that each termination rests generally atop its respective mounting pad 24; and (d) directing laser energy 70 from the diode laser 50 to at least one of the mounting pads 24 from the second side of the substrate 14 for a predetermined time, such that the solder paste atop the at least one of the mounting pads 24 is melted.
