Printed circuit board circuit strengthening system

This creation is about a printed circuit board wiring improvement technology, especially a printed circuit board circuit strengthening system that increases circuit strength and reduces stress concentration.

General electronic products are composed of several electronic components arranged on a circuit board to form a complete circuit structure, so that all electronic components function to achieve product efficacy. However, the current development of electronic products tends to be light, thin, short, and more efficient, resulting in the miniaturization of various electronic components. For example, if a circuit board carrying various electronic components is changed from a rigid substrate to a flexible flexible substrate, the circuit board is so. It can be bent and deformed according to the structure of the electronic product, so that the mounting circuit board only needs to use a limited narrow space, which is helpful to achieve the purpose of reducing the volume of the electronic product.

When the conventional printed circuit board is used for bending, the circuit pattern on the circuit board is pulled or squeezed by stress, which may cause the circuit to break. However, it affects the electrical functions of the product, especially as shown in Figure 1. The line width of a circuit pattern doubles sharply after passing through a turning point, resulting in uneven distribution of bending stress, and the circuit is more likely to break during the bending process. .
