Description

SYSTEM-IN-PACKAGE AND AEROSOL SENERATING APPARATUS COMPRISING THE SAME

The present invention relates to a system-in-package and an aerosol-generating device comprising the same.

In recent years, there has been an increasing demand for alternative methods that overcome the disadvantages of conventional cigarettes. For example, there is a growing need for a method of generating an aerosol as the aerosol generating material in the cigarette or liquid reservoir is heated rather than a method of generating an aerosol by burning a cigarette.

When using a method for generating an aerosol and a device using the same, portability may be an important part for a user. Miniaturization of the aerosol generating device can be a way to increase portability, and expectations for miniaturization of internal components are increasing in order to be manufactured in a compact size while maintaining existing functions.

Although the size of the cigarette has been reduced, the size of the aerosol generating device has not been remarkably reduced in terms of portability. Users may require a smaller size aerosol generating device for easy carrying and space utilization.

However, when the size of the aerosol-generating device is reduced for ease of carrying by the user, the internal components of the aerosol-generating device are densely packed and an overheating state may be induced. If the continuous heating operation is performed while the aerosol-generating device is overheated, components of the aerosol-generating device may be damaged and a problem may occur.

In addition, external foreign substances may be introduced or generated due to the use of the aerosol generating device. For example, foreign substances may be introduced into the aerosol generating device due to droplet generation according to the aerosol generation or leakage of a liquid component of the cigarette. When foreign substances are introduced or generated inside the aerosol generating device, functions of internal components of the aerosol generating device may not be properly exhibited.

Various embodiments are intended to provide a system-in-package and an aerosol generating device including the same as a method for improving the above-described problems. The technical tasks to be achieved through the various embodiments may not be limited to the above-described technical tasks.

As a technical means for achieving the above technical problem, a system-in-package (SIP) according to an aspect includes a micro controller unit (MCU), a sensor module, and a heating integrated circuit (IC) , a memory, a charger IC, and may include at least one of a communication module.

According to another aspect, an aerosol-generating device comprises a heater assembly for heating a cigarette inserted into the aerosol-generating device, a battery for supplying power to the heater assembly, and a system-in package (SIP), the system In-package is a wafer level package (WLP) in which at least one of a micro controller unit (MCU), a sensor module, and a heating integrated circuit (IC), memory, charging IC, and communication module is mounted (integrated) )can do.

The aerosol generating device may employ a system-in-package to reduce the mounting space. Devices mounted on a printed circuit board (PCB) and performing functions may form an on-chip (on-chip) form and/or a module form, and may be bundled as a package on one wafer. The components of the aerosol generating device performing various functions are configured as a bundle, thereby reducing the size of the housing of the aerosol generating device to increase portability. In addition, the aerosol generating device may mount the components in a system-in-package, thereby increasing the space utilization inside the aerosol generating device.

The aerosol generating device may protect components inside the package from foreign substances introduced and/or generated from the outside by molding surrounding the package. When the aerosol generating device detects a foreign material due to contact with the molding, the heating operation of the heating unit may be controlled in a standby state to prevent safety problems due to a short circuit or the like. The package that can be mounted on the aerosol generating device can prevent external foreign substances such as droplets, moisture, and dust from coming into contact with components inside the package by molding.

As such, the molding of the system-in-package that may be included in the aerosol generating device may dissipate heat from internal components that may be generated due to a heating operation, etc. as well as foreign substances. In addition, as the system-in-package is configured, it detects the temperature of each part of the package that is sensed, determines whether the system-in-package is overheated, and controls the heating operation of the heating unit to the standby state when the overheated state is reached to prevent problems due to overheating can do.
