Abstract
PURPOSE:To form substantially uniform insulating coating layer on an electronic circuit substrate and to reduce its cost by forming a moisture resistant insulating coating agent of specific low boiling point solvent, and resin soluble in the solvent. CONSTITUTION:An electronic circuit substrate 1 on which electric elements are mounted is coated with a moisture preventive insulating coating agent. The agent contains low boiling point solvent containing a solvent having 30-50 deg.C of boiling point, and 5-20wt.% of resin soluble in the low boiling point solvent. The agent has 5-20cps of its viscosity. The substrate 1 is formed of paper substrate phenol resin copper-extended laminated plate or paper base material epoxy resin copper-extended laminated plate. Thus, a substantially uniform insulating coating layer 4 is formed on the substrate 1 to reduce its cost.
