摘要:
A copper foil for use in making a printed wiring board and a copper clad laminate comprising the copper foil are herein disclosed and the copper foil is characterized in that a metal chromium layer is formed on at least one side of the copper foil by vapor deposition or characterized in that one side of the copper foil is supported by a carrier through a releasing layer and a metal chromium layer is formed on the other side of the foil by vapor deposition. The copper foil is excellent in the adhesion to various substrates (the peel strength between the substrate and the copper foil), moisture resistance, chemical resistance and heat resistance and therefore, the copper foil can suitably be used in the production of printed wiring boards.

Present invention provides an electro-deposited copper foil having the equivalent low-profile surface as in a conventional low-profile electro-deposited copper foil and extremely large mechanical strength and a method for manufacturing the same. The electro-deposited copper foil is formed by depositing fine copper crystal grains having a small deviation of grain-diameter. The electro-deposited copper foil has a low-profile and glossy surface and has extremely large mechanical strength expressed by a tensile strength as received of 70 kgf/mm2 to 100 kgf/mm2 and has a tensile strength after heating (180° C. for 60 minutes) corresponding to 85% or more of the tensile strength as received. The electro-deposited copper foil is manufactured by electrolysis using a sulfuric acid base copper electrolytic solution containing a compound composed of a benzene ring having a sulfo group bonded thereto, a sulfonate of an active sulfur compound and a polymer of a quaternary ammonium salt having a cyclic structure.

An object of the present invention is to provide an electro-deposited copper foil having the equivalent low-profile surface as in a conventional low-profile electro-deposited copper foil and extremely large mechanical strength and a method for manufacturing the same. To achieve the object, the electro-deposited copper foil is formed by depositing fine copper crystal grains having a small deviation of grain-diameter that has never been obtained in the art. The electro-deposited copper foil has a low-profile and glossy surface and has extremely large mechanical strength expressed by a tensile strength as received of 70 kgf/mm2 to 100 kgf/mm2 and has a tensile strength after heating (180° C. for 60 minutes) corresponding to 85% or more of the tensile strength as received. The electro-deposited copper foil is manufactured by electrolysis using a sulfuric acid base copper electrolytic solution containing a compound composed of a benzene ring having a sulfo group bonded thereto, a sulfonate of an active sulfur compound and a polymer of a quaternary ammonium salt having a cyclic structure. The electro-deposited copper foil is suitable for manufacturing TAB substrate having a flying lead as shown in the figure.

摘要:
A central processing unit sets which of the following modes a data processing device is to operate in accordance with a user program. The high-speed operation mode allows operation within a first range in which an external supply voltage is relatively high. The wide voltage range operation mode allows operation within a second range in which the external supply voltage includes the first range and a relatively low voltage range, and an upper limit of a frequency of the first clock in the wide voltage range operation mode is lower than an upper limit of a frequency of the first clock in the high-speed operation mode. The frequency of the first clock in the low power consumption operation mode is lower than the frequency of the first clock in the high-speed operation mode and the frequency of the first clock in the wide voltage range operation mode.

A threaded joint for steel tubes has a contact surface (30) including a threaded portion and a non-threaded metal-to-metal contact portion. The contact surface of at least one of a pin and a box of the joint is coated with a first plating layer (34) made of a Cu—Zn alloy or a Cu—Zn-M1 alloy (wherein M1 is at least one element selected from Sn, Bi, and In). An undercoat (32) of one or both of a Ni plating layer (32a) and a Cu plating layer (32b) and an overcoat of a Sn-M2 alloy plating layer (36) (wherein M2 is one or more elements selected from Bi, In, Ni, Zn, and Cu) may be formed below and above the first layer, respectively. A solid lubricating coating (38a) and a viscous liquid or semisolid lubricating coating (38b) may also be formed atop the plating layer as a lubricating coating (38).
