Method of manufacturing tuner chassis

摘要

A method of manufacturing a tuner chassis, in which a tuner chassis assembly is entirely dipped in a molten solder bath to effect the plating of the chassis surface with a solder layer, and thereafter the chassis assembly is dipped in an oil bath heated to a temperature higher than the melting temperature of the solder and then raised, whereby the state of solder plating on the chassis surface is improved by making use of the mechanism that oil forms an oil film on the chassis.
