Soldering ceramic body into electrical component - includes using intermediate tin coating and lead-tin coating not applied electrolytically

摘要

In a method of soldering a ceramic body of an electrical component, e.g. microwave resonator, into a metal housing, the body with an electrically conducting coating of Cu or Ni-Cu, is plated with a 1-2 mu thick coating of Sn, while the surface of the housing to which it is soldered in plated with a 20 mu thick coating of a high m.pt. Pb-Sn alloy, e.g. by cold rolling on the surface. ADVANTAGE - Avoids the need for electrolytic plating from a Pb-Sn bath and environmental consequences.
