Abstract
A method for assembling components includes assembling a first component including solder bumps with a second component including connectors. The assembly of the components is preceded by pre-treating the first and second components wherein the solder bumps are contacted with a pre-treatment liquid configured to at least partially remove an oxide layer initially present on the solder. The pre-treatment liquid is an aqueous solution containing carboxylic acids or polycarboxylic acids. The assembly of the components is carried out after the pre-treatment in the absence of liquid or gas flux.
