Description

Technical Field

[0001] The utility model relates to the field of flexible circuit boards, in particular to a gold finger punching die for a flexible circuit board. Background Art

[0002] Flexible circuit boards are a type of thin-film circuit boards that consist of a flexible substrate and conductive copper foil. Compared with traditional rigid circuit boards, flexible circuit boards have better flexibility and bending properties and are suitable for applications that require bending, folding or bending. Flexible circuit boards are commonly used in mobile phones, tablets, cameras, automotive electronics and other products to achieve a more compact and lightweight design. Their advantages include light weight, small size, easy installation and maintenance, etc.

[0003] Gold finger punching die is a tool used to manufacture the connector part of flexible circuit boards. Gold fingers are a connector structure on flexible circuit boards, which are used to connect circuit boards with other devices or electronic components. Gold finger punching die processes the gold finger part of flexible circuit boards into the required shape and size through cutting, stamping and other processes. These molds are usually made of high-hardness alloy steel or special materials, with high precision and wear resistance, which can ensure the accuracy and quality of gold finger processing. Gold finger punching die plays a key role in the production process of flexible circuit boards and affects the performance and reliability of connectors.

[0004] Some existing traditional punching dies for gold fingers of flexible circuit boards fix and punch the gold fingers of flexible circuit boards by pressing between upper and lower dies. However, during the process of the dies moving up and down and during the punching process, the flexible circuit board may expand and shrink during the punching process due to its easy expansion and contraction, which affects the accuracy of gold finger punching. In addition, some existing traditional punching tools for gold fingers of flexible circuit boards are only provided with an upper stripper plate to prevent materials from being adsorbed on the upper template, but the lower template lacks a discharge component, which causes the flexible circuit board to sink into the lower mold groove, making it inconvenient to take out materials.
