Abstract
PURPOSE:To produce a Cu-Sn composite material for electronic parts having improved luster, electric resistance and solderability by tinning a Cu material to a specified thickness, introducing the tinned material into a treating furnace, blowing combustion gas on the Sn layer under specified conditions to melt the Sn layer and rapidly cooling the molten layer. CONSTITUTION:A Cu or Cu alloy bar or wire is electroplated with Sn or an Sn alloy to 0.3-10mum thickness and introduced into a treating furnace. Fuel is mixed with air in <=1 air ratio (value obtd. by dividing the amt. of air actually used to burn fuel by the theoretical amt. of air required to burn the fuel) and the fuel is burned. The resulting gas having <=0.1vol.%, preferably 0.90-0.95% oxygen concn. is introduced into the treating furnace and blown on the Sn or Sn alloy layer at >=1m/sec velocity to heat the layer. At this time, the interior of the furnace is kept under >=1atm and the layer is melted and rapidly cooled. Thus, a Cu-Sn composite material useful for electronic parts is obtd.
