Abstract

PURPOSE:To eliminate a troublesome work of applying and removing a masking tape to and from a land area for components to be attached later by a method wherein a 2nd resist layer which is not melted at the temperature of a solder bath but is melted at the temperature of a solder iron is formed on a land resist layer on a board. CONSTITUTION:A conventional land resist layer 3 is formed on a conductor layer 2 formed on a board 1 as a 1st insulating layer. A resist layer 4 which has a melting point lower than that of the resist layer 3 is formed on the resist layer 3 as a 2nd insulating layer. The resist layer 4, i.e. the 2nd insulating layer, is made of material which is not melted at the processing temperature of a solder bath but is melted at the temperature of a solder iron. As a land area (a) for components to be attached later on the board 1 is protected by the resist layer 4, even if the board 1 is subjected to a solder dip treatment in the solder bath, the solder does not adhere to the lands of the components to be attached later. With this constitution, the construction of applying a masking tape can be eliminated and the adhesion of solder at the time of the solder dip treatment can be securely avoided by a very simple means.
