Problems solved by technology

Generally, the conductive coil on the PCB is set on the surface of the PCB. Therefore, when a large current is passed into the conductive coil, the conductive coil has a large loss in the air, which greatly affects the electromagnetic performance of the PCB product. The industry has continuously put forward higher requirements for current density. Therefore, the current design of conductive coils on PCBs cannot meet such requirements, which limits the application and development of products.

Abstract

The embodiment of the invention relates to a circuit board processing method, comprising the following steps of: fixing a conductive coil on a first core board, arranging the conductive coil between the first core board and a second core board, and for leading the ports of the conductive coil out of the surface of the circuit board, drilling at the position of the ports, and electroplating at thepositions of port leading-out holes to obtain an electroplated layer for leading the ports out of the surface. The embodiment of the invention also provides a corresponding circuit board. Thus, the conductive coil is embedded in the circuit board and is not exposed on the surface of the circuit board, no loss is produced when current is introduced as the conductive coil is not exposed in the air,the electromagnetic properties of PCB (Printed Circuit Board) products are guaranteed, and especially the invention can be widely applied in the power supply industry with high requirement for current density.

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to a circuit board processing method and a circuit board. Background technique [0002] The printed circuit board (PCB) is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Generally, the conductive coil on the PCB is set on the surface of the PCB. Therefore, when a large current is passed into the conductive coil, the conductive coil has a large loss in the air, which greatly affects the electromagnetic performance of the PCB product. The industry has continuously put forward higher requirements for current density. Therefore, the current design of the conductive coil on the PCB cannot meet such requirements, which limits the application and development of the product. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provid...
