Stereoscopic printed circuit board (PCB), and preparation method of stereoscopic printed circuit board

Abstract

The invention discloses a stereoscopic printed circuit board (PCB), and a preparation method of a PCB, and belongs to the field of a circuit. The stereoscopic PCB comprises at least one circuit layer and at least one insulation layer, wherein the number of circuit layers is greater than one, neighboring two circuit layers are separated by the insulation layer, and the neighboring circuit layers are attached to the insulation layer; and the at least one insulation layer comprises a first-type insulation layer, the first-type insulation layer at least comprises a first portion and a second portion, the first portion of the first-type insulation layer is disposed at a first plane, the second portion of the first-type insulation layer is disposed at a second plane, and the first plane is different from the second plane. By using the technical scheme provided by the invention, the stereoscopic PCB can be suitable for the demands of electronic devices in different shapes, multiple planar PCBs are replaced by use of one stereoscopic PCB, and the impedance difference caused by use of the multiple planar PCBs is avoided.

Description

technical field [0001] The invention relates to the field of circuits, in particular to a three-dimensional printed circuit board and a preparation method of the three-dimensional printed circuit board. Background technique [0002] PCB (Printed Circuit Board, printed circuit board) is an important electronic component and a support for electronic components. Almost every kind of electronic equipment, from small electronic watches and calculators to large computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, printed circuit boards will be used. After electronic equipment adopts printed circuit boards, due to the consistency of similar printed circuit boards, manual wiring errors are avoided, and automatic insertion or placement of electronic components, automatic soldering, and automatic detection can be realized, ensuring the quality of electronic equipment. Improve labor producti...

AI Technical Summary

Problems solved by technology

[0005] The assembly of multiple planar PCBs increases the complexity of the process, and at the same time, the stability of electronic equipment will also be affected

For the same signal, the impedance generated by each PCB is inconsistent. Although each PCB meets the design requirements, there will be signal integrity problems when connected together.
