A printed circuit board includes an insulating layer, a circuit pattern on the insulating layer, and a surface treatment layer on the circuit pattern. The surface treatment layer includes a bottom surface having a width wider than a width of a top surface of the circuit pattern.

Printed circuit board and method of fabricating the same

A circuit board according to an embodiment includes: an insulating layer including a through hole and a via disposed in the through hole and wherein the via including a first metal layer on an upper surface of the insulating layer and an inner wall of the through hole; and a second metal layer disposed in the through hole, and the an upper surface of the second metal layer includes a protruding portion that does not overlap an upper surface of the insulating layer in a vertical direction and is located higher than the first metal layer.

Circuit board comprising via

A method of manufacturing a printed circuit board includes providing an insulating layer, forming a plating seed layer on the insulating layer, forming a first circuit pattern on the plating seed layer and a second circuit pattern on the first circuit pattern, and forming a top metal layer on the second circuit pattern. The second circuit pattern can be thinner than the first circuit pattern, and the top metal layer can be wider than the second circuit pattern.

Method of manufacturing printed circuit board

A printed circuit board includes: an insulating layer; a plating seed layer disposed on the insulating layer; a circuit pattern layer disposed on the plating seed layer and formed of copper (Cu); and a surface treatment layer disposed on the circuit pattern layer and formed of gold (Au), wherein the circuit pattern layer includes a corner portion of an upper portion which has a curvature, and wherein the corner portion of the circuit pattern layer is a boundary surface between the top surface and a side surface of the circuit pattern layer, and the boundary surface has a concavely curved surface.

A printed circuit board includes: an insulating layer; a plating seed layer disposed on the insulating layer; a circuit pattern layer disposed on the plating seed layer and formed of copper (Cu); and a surface treatment layer disposed on the circuit pattern layer and formed of gold (Au), wherein a width of a bottom surface of the surface treatment layer is narrower than a width of a top surface of the plating seed layer, wherein the bottom surface of the surface treatment layer includes: a first portion contacted with the circuit pattern layer; and a second portion non contacted with the circuit pattern layer, and wherein a width of a top surface of the circuit pattern layer is narrower than a width of a bottom surface of the circuit pattern layer.

Disclosed are a printed circuit board and a method of manufacturing the printed circuit board. The printed circuit board includes an insulating layer, and a circuit pattern formed on the insulating layer, wherein the circuit pattern includes a first circuit pattern formed on the insulating layer and including a corner portion of an upper portion which has a predetermined curvature and a second circuit pattern formed on the first circuit pattern and configured to cover an upper surface of the first circuit pattern including the corner portion.

The present invention relates to amidoxime derivatives of the formula (I): ##STR1## wherein R.sub.1 is a C.sub.1-3 alkyl or allyl group, a methyl group substituted by chlorine or fluorine atom or ethoxycarbonyl or diethyldithiophosphate group, a phenoxymethyl group unsubstituted or substituted by chlorine atom, a C.sub.2 alkoxy or phenoxy group unsubstituted or substituted by chlorine atom or ethoxycarbonylethoxy group, a phenyl group unsubstituted or substituted by chlorine or fluorine atom, a benzyl group unsubstituted or substituted by chlorine atom, or a morpholine group; R.sub.2 is a phenoxymethyl or phenoxyethyl group substituted by chlorine atom, a phenyl group substituted by chlorine atom or methoxy group, or an ethoxy group. The compounds of the invention have a extremely high selectivity between paddy rice or crop plants and weeds and a strong activity on weeds. Moreover, the compounds have a very low phytotoxicity to paddy rice and crop plants.
