Abstract：

The cross-applicability of punching dies arises because they conform with the product demand for 3C industry. With the development of IC (Integrated Circuit) processing technology, passive components are being increasingly miniaturized, ranging from early middle-chips to existing macro-chips. The increasing miniaturization of passive components leads to a requirement for smaller aperture of composite paper bags, however, depends on the design of the punching dies. Good die design for blanking can reduce the burr of the packaging bags and reach the accuracy required. This study utilizes an Image Vision System to measure the burr size of processed composite materials in order to estimate which condition is better for micro dies. The relationship was established between input parameters and output via a neural network. This can help to anticipate the burr size under any clearance, and contributes to the design and application of smaller dies in the future.
