Method of laser soldering |
| abstract |
A method of soldering electrical lead strands (13) (of a width at least .3 inch) to a printed electrical path. The path is planted on an alumina ceramic substrate (15) and a solder pad (24) is attached to a portion of the path. A flat surface portion of each lead strand (13) is forced into full interengagement with a pad (24), a CO2 defocused laser beam (28) is directed onto the soldering assembly with the beam (28) controlled to have a beam power of at least 100 watts, a beam spot diameter (27) no less than the width of the lead strand (13) and no greater than the width of the pad (24), and a beam on-time effective to exert a controlled thermal radius on the soldering assembly to reflow only a preselected portion of the pad (24) and effect a solder joint between the pad (24) and strand portion (13), the joint having a strength of at least 400 grams. |
