摘要:
Disclosed is a substrate for semiconductor package and a wire bonding method using thereof. The substrate is provided with at least one reference mark on its surface to check a loading position and a shift state of a solder mask. The reference mark is composed of a combination of a reference pattern and a solder mask opening and is positioned in any location on an outer peripheral edge of a die attachment region. The reference mark may take various shapes. A method for checking a solder mask shift using the reference mark includes comparing a design value of the reference pattern and the solder mask opening with the reference pattern and the solder mask opening, which are formed in an actual material. After the solder mask shift is calculated, a wire bonding coordinate is newly constructed in consideration of the solder mask shift. This minimizes the wire bonding error.

A color reproduction correcting system and method, and a video display device and method can reproduce original color by considering signal source and display device. Each signal source information and each display device information can be stored. The signal source and the display device, which are currently used (e.g., corrected), can be determined, for example, by a user selection. In one embodiment, the signal provided from a transmission side can be inverse gamma-corrected based on a corresponding signal source, and a colorimetric error of the inverse gamma-corrected signal is preferably corrected using corresponding signal source information and display device information. The corrected colorimetric error signal can be gamma-corrected based on a corresponding display device and then can be displayed on the corresponding display device.

Disclosed is a binder, which comprises polymer particles obtained by polymerization of: (a) 1˜80 parts by weight of a (meth)acrylic acid ester monomer; (b) 1˜20 parts by weight of an unsaturated carboxylic acid monomer; and (c) 0.001˜40 parts by weight of a vinyl monomer, based on 100 parts by weight of the binder polymer, and which allows electrode active material particles capable of lithium intercalation/deintercalation to be fixed and linked among themselves, and between the particles and a collector. An electrode comprising the binder, and a lithium secondary battery having the electrode are also disclosed. Further, a method for evaluating interrelation between wettability of a binder to an electrolyte and quality of a battery comprising the binder is disclosed. The binder shows excellent adhesion as well as excellent wettability to an electrolyte, and thus can improve rate characteristics and lifespan characteristics of a battery, when used in an electrode for a lithium secondary battery.
摘要:
Disclosed is a binder comprising composite polymer particles having a structure formed of two or more phases different in terms of cell property, adhesive strength and/or coating property. The binder provides excellent cell property, adhesive strength and coating property, and thus the binder is used in an electrode of a lithium secondary battery to improve the cell performance.
