Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a circuit board with a step groove. Background Art

[0002] With the development of small and diversified electronic products, high-frequency and high-speed printed circuit boards are required for new communication modules, and traditional printed circuit boards can no longer meet the needs of high frequency and high speed. With the development of high-frequency microwave technology, the functional requirements for high-frequency microwave printed circuit boards are also increasing. In order to meet the needs of fixing and miniaturizing some special functional devices or installing parts, the overall device height needs to be reduced after assembly. The constraints of space and safety make traditional planar design unable to meet the needs of many circuit boards in the electronic field. Therefore, circuit boards with stepped groove structures gradually occupy the market. On the one hand, the stepped groove structure can maximize the use of the space inside the circuit board and provide technical support for the diversified development of electronic products; on the other hand, when customers are soldering components, they need to overlap or avoid other components at certain times to ensure the safety of electrical components, which further highlights the superiority of the stepped groove structure.

[0003] However, the step groove circuit boards currently on the market have reserved pin holes for connecting electronic components, and the inner diameter of the pin holes is usually larger than the diameter of the pins. Therefore, when soldering, it is troublesome to manually fix the electronic components; and when the electronic components are subjected to external vibrations, there is a possibility of desoldering. Therefore, a circuit board with a step groove is provided to solve the above problems. Utility Model Content
