Document Type and Number:
WIPO Patent Application WO/2013/136729
Kind Code:
A1
Abstract:
Provided is a laminated board that is provided with an insulating layer and copper foil positioned on at least one surface of the insulating layer, and that is used in a device mounting substrate obtained by forming a conductor circuit by etching the copper foil. The copper foil etching rate is between 0.68µm/min and 1.25µm/min under conditions where the laminated board it immersed in a sulfuric acid/hydrogen peroxide etching liquid comprising 55.9g/L of sulfuric acid and 19.6cc/L of 34.5% hydrogen peroxide and at a temperature of 30°C+1°C.
