Manufacturing method of electronic product and electronic product

Abstract

The invention discloses a manufacturing method of an electronic product and the electronic product. The electronic product comprises a PCB and a USB Type-C connector, the USB Type-C connector is connected with a high-speed signal line DP and a high-speed signal line DM, the high-speed signal line DP is provided with a first disconnection end and a second disconnection end, and the high-speed signal line DM is provided with a third disconnection end and a fourth disconnection end; the manufacturing method comprises the following steps: detecting whether common-mode interference exists in the electronic product, and if the common-mode interference exists, arranging a common-mode inductor between the high-speed signal line DP and the high-speed signal line DM; and if the common-mode interference does not exist, a resistor R1 is connected between the first disconnection end and the second disconnection end, and a resistor R2 is connected between the third disconnection end and the fourth disconnection end. For an electronic product without common-mode interference, a common-mode inductor is not selected during design, so that the production cost is saved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a manufacturing method of an electronic product and an electronic product. Background technique [0002] When designing electronic products, it is often necessary to consider the electromagnetic interference of electronic products or the impact of the electromagnetic radiation generated by them on the human body, the power grid in public places and other electrical products. (Electro Magnetic Compatibiliy) Electromagnetic compatibility and other issues. [0003] In the prior art, by connecting a common mode inductor to the USB / TYPE-C connector, the common mode interference can be well suppressed. However, due to the continuous upgrading of the packaging and testing process of chip manufacturers and the continuous improvement of PCB design capabilities, many electronic products may not necessarily have EMI / EMC crosstalk after they are designed. If there is no common ...

Problems solved by technology

However, due to the continuous upgrading of the packaging and testing process of chip manufacturers, coupled with the continuous improvement of PCB design capabilities, many electronic products do not necessarily have EMI / EMC crosstalk after they are designed.

For those without common-mode interference, the use of common-mode inductors during design will cause waste and increase unnecessary costs
