Abstract

Method of production of solder masked electric circuit boards, which includes: - Form a circuit on substrate; - Coat a negative photosensitive weld-resist on circuit board; - Expose negative film under the light and develop; the features are: the negative photosensitive weld-resist can electrolyze and the coating of weld-resist is transferred to base by conductivity and processed on circuit board.
