Technical Field

[0001] The utility model relates to the field of circuit board production, and specifically relates to a waste discharging structure of a circuit board punching die. Background Technique

[0002] A circuit board is composed of integrated circuits, crystal oscillators, trimming capacitors, and printed circuit boards. The names of circuit boards include: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, etc. The circuit board miniaturizes and visualizes the circuit, and plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances. It is mainly used to connect various electronic components in electronic devices and serves as a structural support.

[0003] In the prior art, punching in a circuit board is a way of forming. In actual production of circuit boards, in order to improve production efficiency, for various products of different sizes, basically plates of 500 cm * 400 cm in size are used for panel plating to facilitate uniform electroplating and improve the utilization rate of dry film during pattern transfer. Due to the existence of panel plating, punching becomes necessary. The role of punching is to use a steel die to punch a large board in production into shipping units.

[0004] However, when the existing punching die processes a circuit board, a large amount of waste will be generated. The waste generated when the punching die is in use is not convenient to clean and recycle. The staff needs to stop the machine first to clean the waste in the punching die, which reduces the production efficiency. Content of the Utility Model
