Description

Technical Field

[0001] The utility model relates to the technical field of FPC positioning correction, in particular to an FPC positioning correction structure. Background Art

[0002] The FPC flexible printed circuit board, also known as the flexible circuit board (Flexible Printed Circuit, abbreviated as FPC), is a highly reliable and flexible printed circuit board made of polyimide or polyester film as the substrate. It has the characteristics of high wiring density, light weight, thin thickness, and good bendability, and can provide excellent electrical performance, meeting the design requirements of smaller and higher density installations, helping to reduce the assembly process and enhance reliability. It is the only solution to meet the miniaturization and mobility requirements of electronic products. The FPC flexible printed circuit board can be freely bent, wound, and folded, can withstand millions of dynamic bends without damaging the wires, can be arranged arbitrarily according to the spatial layout requirements, and can move and stretch arbitrarily in three-dimensional space, so as to achieve the integration of component assembly and wire connection, greatly reducing the volume and weight of electronic products, and meeting the needs of the development of electronic products towards high density, miniaturization, and high reliability.

[0003] For the welding process of FPC (flexible printed circuit board), it is very important to correct the pasted terminals, which can ensure the accuracy of the welding position, thus avoiding poor welding, short circuit or other potential problems. Before welding the FPC, you can take the following steps to correct the pasted terminals: Visual inspection: First, visually inspect the terminals on the FPC to ensure that they are correctly pasted in the expected positions without offset or tilt. Using fixtures: Design and use special fixtures to fix the FPC, which helps to maintain its stability during the welding process and prevent the terminals from moving. Using positioning marks: Set positioning marks or reference points on the FPC, which helps to more accurately position the terminals during the welding process. Manual correction: For a small number or special cases, manual tools can also be considered to fine-tune the position of the terminals. Through the above steps, ensure that the positions of the pasted terminals are accurate before welding the FPC, thus improving the welding quality and product reliability.

[0004] During the welding process of the existing FPC (flexible printed circuit board), it is necessary to limit the terminals on the FPC through a device and then weld on the terminals. However, the existing device cannot automatically adjust the position of the terminals on the FPC. When the terminals are offset, the welding process can only be terminated, thus reducing the production efficiency of the device, affecting the welding quality, and reducing the yield rate.
