    摘要: An integrated circuit chip is joined to a substrate by first applying solder to the substrate and/or the IC chip, and then applying diol and /or polyol and/or ether derivatives thereof to the substrate. The IC chip is placed in contact with the applied diol/polyol and the resulting assembly is heated in a reducing atmosphere. This process avoids the application of liquid flux compositions and the necessity to remove the flux or flux residues in separate cleaning steps.
