Summary


Voids in solder joints are largely a function of differential pressure between vapor pressure of the gases inside of the joint and environmental conditions. By entering joints still in their liquid state into decompression chambers, voids can be eliminated. Equipment has been developed to achieve void-free joints under these conditions utilizing modern condensation reflow technology.
