Abstract

Embodiments of the invention disclose a method for processing a groove on a printed circuit board, the printed circuit board and an electronic device. The method for processing the groove on the printed circuit board comprises: processing the groove, the dimension of which is matched with that of a heat-dissipating metal base on a first board set; fixedly arranging the heat-dissipating metal base in the groove processed in the first board set; stitching a second board set with the first board set and thus a third board set is formed; providing a groove in the surface of the second board set after stitching so as to form a blind groove for installing components, wherein partial or all bottom surface of the blind groove is arranged on the heat-dissipating metal base and at least one surface of the heat-dissipating metal base is exposed; and the depth of the blind groove in the vertical direction on the surface of the third board set is larger than the thickness of the second board set after stitching. The scheme provided in the embodiments of the invention is benefit to promote product miniaturization, integration and cost control.

Description

technical field [0001] The invention relates to the field of printed circuit board manufacturing, in particular to a method for processing grooves on the printed circuit board, the printed circuit board and electronic equipment. Background technique [0002] It is applied to high heating components such as power amplifiers (PA, Power Amplifier) ​​in many electronic devices. For example, PA is applied in high-power wireless base stations. The core of PA lies in matching design, heat dissipation design, linearity, consistency and efficiency, etc. Among them, except for matching, other characteristics are closely related to heat dissipation. Heat dissipation is a major factor affecting efficiency and linearity. Among the existing heat dissipation solutions for components, the heat dissipation metal-based printed circuit board (PCB, Printed Circuit Board) is a more effective solution. Among them, the existing heat dissipation metal-based PCB is used to carry PA or other compone...
