Embodiment Construction
[0022] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0023] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of...

The invention relates to a flexible circuit board, a wearable device and electronic equipment, and the flexible circuit board comprises: a substrate which is provided with a first surface; an electronic element which is arranged on the first surface, wherein the electronic element comprises a plurality of pins; a plurality of welding pads which are arranged on the first surface and are positionedon one side of the electronic element; a signal line, wherein one end of the signal line is connected to the welding pads, and the other end of the signal line is connected to the pins, wherein the signal line extends from the welding pads and is branched into a first routing line and a second routing line, the first routing line and the second routing line are converged at the pins, and the current-carrying capacity of the first routing line is greater than the current-carrying capacity of the second routing line. The flexible circuit board provided by the invention has relatively strong ESDimpact resistance. Besides, line breakage may be caused when the flexible circuit board is bent, and the probability that the first wiring and the second wiring which are connected in parallel are broken at the same time is low, so that the bending resistance of the flexible circuit board is effectively improved.
Description
technical field [0001] The invention relates to the technical field of circuit boards, in particular to a flexible circuit board, a wearable device and electronic equipment. Background technique [0002] Flexible printed circuit board (FPC) is widely used in various electronic products due to its excellent characteristics such as high wiring density, light weight, thin thickness, and good bendability. Electronic components such as IC chips are usually welded on flexible circuit boards. During use, static electricity from the human body, the surrounding environment, and even the interior of the device will generate instantaneous high voltage and cause damage to electronic components. The above phenomenon is called Electrostatic Discharge (ESD) ). Electrostatic discharge may cause the signal lines on the flexible circuit board to be broken down, making it difficult to detect and repair. Contents of the invention [0003] Based on this, it is necessary to provide a flexible...
