▎ 摘 要
NOVELTY - Double-layer copper sheet oxidation fixture comprises an upper rectangular frame (1) and a lower rectangular frame (2) connected by two side plates (3). The two side plates are arranged opposite to each other, and the two of the side plates are provided with multiple vent holes (4). USE - Used as double-layer copper sheet oxidation fixture. ADVANTAGE - The oxidation fixture: achieves the simultaneous oxidation effect of the upper and lower layers of copper sheets; achieve the effect of two layers of uniform oxidation; improves the situation that the ceramic layer and the copper layer are not densely bonded, the bonding strength is low, and they are easy to bulge in the existing ceramic copper cladding technology. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for oxidation method of oxidized copper oxide sheet. DESCRIPTION OF DRAWING(S) - The drawing shows a structural diagram of double-layer copper sheet oxidation fixture. Upper rectangular frame (1) Lower rectangular frame (2) Side plate (3) Vent hole (4)
