摘　　要：为提高室温印压铜片所得微孔的质量,减少微孔内部裂纹以及获得孔径更小的微孔,提出加热印压的新工艺方法。通过大量印压实验,对影响微孔成形的各因素进行分析与验证,得到最佳的加热印压工艺参数。结果表明:采用加热印压可获得孔径更小的微孔,而且微孔边缘隆起高度有所降低,成形质量更高。In order to improve the quality of the micropore obtained by printing the copper sheet at room temperature, reduce the internal cracks of the micropore and obtain the micropore with smaller diameter, a new heating coining process was proposed.Through a large number of coining experiments, the factors affecting the micropore forming were analyzed and verified,and the best heating coining parameters were obtained.The results show that the micropore with smaller pore diameter can be obtained by heating coining, the uplifting height of the edge of the micropore is reduced, and the forming quality is higher.
