Abstract:
A luminescence device used in a backlight unit for lighting or displaying may include a substrate having a first electrode and a second electrode, and an LED chip disposed on the first electrode. A dam is disposed on the substrate. The dam is disposed spaced from the LED chip, and the substrate comprises a direct copper bonding (DCB) substrate including a first copper layer and a second copper layer. The first electrode and the second electrode include respectively a metal film which fills a void of the surfaces thereof.
Abstract:
Disclosed herein are a surface-treated copper foil, a copper-clad laminate plate including the same, a printed circuit board using the same, and a method for manufacturing the same. In detail, the copper-clad laminate plate according to one implementation embodiment of the present invention includes: carrier; a peel layer formed on the carrier; a copper-clad layer formed on the peel layer; and a surface-treated layer formed on the copper-clad layer, in which the surface-treated layer includes a thiol-based compound. Therefore, the present invention provides a printed circuit board capable of improving an adhesive force between a base and a copper-clad layer without treating a roughed surface by forming the surface-treated layer on the copper-clad layer.
