摘要: A method is disclosed for laser bonding two highly reflective electrical members. The first member coated with a coating alloy containing the metal of second and coupling material that well absorbent energy at beam wavelength, has lower melting point than either members, low solubility in solid bond characteristics are selected so as occurs members solidifies solidification front drives molten away from interface toward exterior periphery bond, substantially all solidified strength results alloy. Coating copper lead gold material, then contacting pad provides gold-to-gold TAB tape bonding.
