The present invention relates to a carrier foil-attached metal foil including a release layer having a specific composition and structure, a method of manufacturing the carrier foil-attached metal foil, and a laminate for forming a printed circuit board including the carrier foil-attached metal foil. The laminate for forming a printed circuit board according to the present invention comprises the carrier foil-attached metal foil, so that a defect rate can be minimized.

A surface-treated copper foil includes a treated surface, where the peak extreme height (Sxp) of the treating surface is 0.4 to 3.0 μm. When the surface-treated copper foil is heated at a temperature of 200° C. for 1 hour, the ratio of the integrated intensity of diffraction peak of (111) plane to the sum of the integrated intensities of diffraction peaks of (111) plane, (200) plane, and (220) plane of the treating surface is at least 60%.

This invention relates to a composite mandrel and its processing technology, including: processing, connection, welding, alloy overlaying, tempering after overlaying, polishing, chrome plating etc., on the whole and auxiliary body of mandrel. The composite mandrel includes a plurality of main and auxiliary bodies, the surface is overlaid with high temperature resistant, wear resistant, thermal fatigue resistant alloy, polished, and chrome plated, obtaining the characteristics of wear resistance, thermal fatigue resistance and high temperature resistance. The whole process not only increase the strength, toughness and hardness of the mandrel, improves its service quality, but also prolong the service life. With simple structure and reliable quality, composite mandrel can meet the requirements of different running condition. Whether for new-made mandrels, or for equal diameter renewal of failed mandrels, composite mandrel process can show its advantages of suitable material quantity, energy saving, consumption reduction, and production cost reduction.

A surface-treated copper foil including a treating surface, where the root mean square height (Sq) of the treating surface is in a range of 0.20 to 1.50 μm and the texture aspect ratio (Str) of the treating surface is not greater than 0.65. When the surface-treated copper foil is heated at a temperature of 200° C. for 1 hour, the ratio of the integrated intensity of (111) peak to the sum of the integrated intensities of (111) peak, (200) peak, and (220) peak of the treating surface is at least 60%.
