[0002] With the rapid development of modern technology, electronic products have become ubiquitous in every household. Driven by the market economy, people's expectations for electronic products are becoming increasingly higher, and electronic products are constantly being upgraded. Widely used electronic products in the market all utilize functional components mounted on circuit boards and utilize a stable power supply to achieve their corresponding electronic functions.

[0003] Miniaturized, integrated electronic products are currently the mainstream in the market. During the development process, the circuit substrate, as the core of the electronic product, is difficult for even experienced engineers to design and finalize in one go, requiring product debugging and optimization. Furthermore, miniaturization has reduced the number of debugging locations on the substrate, and redesign and optimization can impact product development cycles. Therefore, existing debugging methods, such as "flying wires" (interconnecting two pads with wires), adding components, and interrupting circuits, all require cutting and modifying the substrate's circuitry.
