    摘要: A fluxless soldering sample pretreating system includes a sample chamber having an opening therein and a sample holder. A sample chamber extension extends outwardly from the opening to define a passageway from the sample chamber extension, through the opening, and into the sample chamber. A fluorine-containing gas is supplied into the sample chamber extension. Am energy source such as a microwave oven surrounds the sample chamber extension. The microwave oven produces microwave energy in the sample chamber extension to form a plasma therein and dissociate the fluorine-containing gas into atomic fluorine. A perforated aluminum plate extends transversely across the passageway and blocks the plasma from traversing the passageway from the sample chamber extension into the sample chamber, while allowing the atomic fluorine to traverse the passageway from the sample chamber extension into the sample holder. A second chamber extension, gas supply and microwave oven may be added to improve uniformity for large samples.

    摘要: A method of soldering a copper layer without the use of fluxing agents by exposing the copper layer to a fluorine-containing plasma. Solder is then placed onto the surface of the copper layer and reflowed. Reflow can take place at low temperatures, atmospheric pressure and in an inert or oxidizing atmosphere using standard solder reflow equipment.

    摘要: A first component is soldered to a second component by placing the first component on the second component with solder therebetween, then ultrasonically vibrating at least one of the first and second components to thereby tack the solder to at least one of the first and second components, and by reflowing the solder. Ultrasonic vibration of at least one of the first and second components to thereby tack the solder is preferably performed for less than one second. A component placer places the first component on the second component with solder therebetween. An ultrasonic vibrator ultrasonically vibrates at least one of the placed first and second components, to thereby tack the solder to at least one of the placed first and second components. A solder reflower reflows the tacked solder to thereby solder the first component to the second component.
