METHOD FOR TINNING OF RADIO ELEMENTS TERMINALS Russian patent published in 2010 - IPC B23K1/20 H01C17/00 

FIELD: technological processes.

SUBSTANCE: invention may be used to manufacture non-wire cylindrical resistors at the operation of nickel-plated copper terminals tinning. Treatment of terminals surface is carried out with active hydrazine-containing flux, containing the following components, wt %: hydrazine dihydrochloride 2.0-4.0, diatomic alcohol 57.0-42.0, surfactant 8.0-4.0, glycerin 33.0-50.0. Then terminals are submerged into melted solder by group method at the temperature of melted solder of 320-400°C.

EFFECT: method provides for high quality of tinning with simultaneous reduction of labour intensiveness of technological process of tinning, which in the end promotes higher efficiency of non-wire cylindrical resistors.
