VAPOR BONDING METHOD |
摘要 |
<p>VAPOR BONDING METHOD Components, printed circuit board assemblies and the like to be interconnected by soldering are appropriately fluxed and placed in an atmosphere of a saturated vapor derived from a heat transfer liquid medium having a boiling point above the melting point of the solder. The heat transfer medium is chosen to have a solubility parameter compatible with the solubility parameter of the flux to eliminate the need for subsequent flux cleaning. An alternate embodiment includes a fatty acid in the heat transfer medium, which under some circumstances can eliminate the need to apply flux to the assembly being soldered.</p> |
