Problems solved by technology

However, at present, the grooves of printed circuit boards are metallized or non-metallized grooves with large dimensions.
This kind of groove design with a single size can only be used to assemble a single component. For additional small chips or power amplifiers and other components that need to be assembled, they need to be mounted on the surface of the printed circuit board, thus increasing the cost. Assembly volume of printed circuit board

Abstract

The invention belongs to the technical field of printed circuit boards and discloses a PCB with a step groove. A first groove is formed in the PCB; a second groove is formed in the bottom of the firstgroove; the cross section area of the second groove is smaller than that of the first groove; the first groove is matched with the second groove to form the step groove; a side wall of the first groove is a nonmetallic side wall; and a circuit pattern is arranged at the bottom of the first groove. According to the PCB with the step groove, through the arrangement of the second groove in the bottom of the first groove, the space in the step groove is more fully utilized; and components of multiple specifications can be arranged in the step groove, so that the assembly volume of the PCB is reduced.

Description

technical field [0001] The invention relates to the technical field of printed circuit boards, in particular to a PCB provided with stepped grooves. Background technique [0002] PCB (Printed Circuit Board), the Chinese name is printed circuit board, as a support for electronic components, it is an important electronic component. [0003] In order to reduce the assembly volume of the printed circuit board, or to assemble components that need to be sunken, step grooves are usually provided on the printed circuit board in existing designs. However, at present, the grooves of the printed circuit board are metallized or non-metallized grooves with large dimensions. This kind of groove design with a single size can only be used to assemble a single component. For additional small chips or power amplifiers and other components that need to be assembled, they need to be mounted on the surface of the printed circuit board, thus increasing the cost. The assembly volume of a printed...
