Description

Substrate, electronic cigarette airflow sensor and electronic cigarette Technical Field The invention relates to the technical field of substrate manufacturing, in particular to a substrate, an electronic cigarette airflow sensor and an electronic cigarette. Background The substrate is a basic material for manufacturing the PCB. Typically, the substrate is a copper clad laminate. In the manufacture of single-sided and double-sided printed boards, holes, electroless copper plating, electrolytic copper plating, etching and the like are selectively processed on a substrate material-copper clad laminate to obtain a required circuit pattern. The substrate has three functions of conduction, insulation and support. The existing substrate is usually a conventional flat plate structure, and a required circuit pattern is formed through a series of processes. In practice, the different electronic devices are arranged directly on the substrate, so that they can be supported and connected by means of the substrate. However, limited by the size of the substrate surface, the number of electronic devices that can be disposed on the substrate is limited.
