SURFACE-TREATED Al SHEET EXCELLENT IN SOLDERABILITY, HEAT SINK USING THE SAME, AND METHOD FOR PRODUCING SURFACE-TREATED Al SHEET EXCELLENT IN SOLDERABILITY |
摘要 |
<p>A surface-treated Al sheet that has excellent adhesion with a plating layer, solder wettability, and soldering strength, and can be preferably used for a heat sink which has excellent heat radiation and can be soldered; a heat sink using the Al sheet; and a method for manufacturing the surface-treated Al sheet at low cost are intended to be provided. A Zn layer is formed on a surface of an Al substrate, and a Ni layer and a Sn layer are formed by plating by displacement plating thereon, or a layer which has a solder flux property and improves thermal emission is further formed on the surface-treated Al sheet. <IMAGE></p> |
