Electronics are the basis of any modern gadget, including vape devices. An analysis of the device’s schematic solutions is necessary to understand the device’s operational algorithms, its functionality, and individual characteristics. During the research of the device’s PCBs, the maximum possible identification of electronic components is carried out, their interaction is analyzed, possible options of the schematic solutions that provide certain functions of the device are analyzed too. This type of analysis can be performed in conjunction with “Feeding signal features, power parameters analysis”, which allows getting additional information about the device’s power parameters and its features. The analysis can be provided for any type of vape device: pod-systems, HnB, oil vaporizers, etc.
