In this embodiment, The location of the non-metallic shielding opening 70 is set below the mobile device housing 50, but it is not limited to this. In other embodiments, the opening location may be set at other positions of the mobile device housing 50 according to the design of the mobile device 40, and The projection area of the non-metallic shielding opening 70 can cover a range consistent with the antenna device 300, so as to avoid abnormalities in the function and signal transmission of the fingerprint recognition chip 320 and the antenna device 300 when the mobile device housing 50 is made of metal. The antenna device 300 is arranged around the fingerprint recognition chip 320 in a surrounding manner to ensure that the antenna device 300 and the mobile device 40 are less interfered by other signals when the antenna device 300 and the mobile device 40 are transmitting information in the near field communication.

請參閱圖4A，圖4A為另一實施例之行動裝置40，相較於圖3A實施例中行動裝置外殼50之一非金屬遮蔽開口70，其投影面積涵蓋指紋辨識晶片320與天線裝置300，在本實施例中，行動裝置外殼50之一非金屬遮蔽開口80會預留一空間，該空間可露出至少一部分指紋辨識晶片320與天線裝置300，且該非金屬遮蔽開口80之投影面積可涵蓋指紋辨識晶片320與天線裝置300。 Please refer to FIG. 4A. FIG. 4A is another embodiment of the mobile device 40. Compared with the non-metallic shielding opening 70 of the mobile device housing 50 in the embodiment of FIG. 3A, the projection area covers the fingerprint recognition chip 320 and the antenna device 300. In this embodiment, a non-metallic shielding opening 80 of the mobile device housing 50 will reserve a space where at least a part of the fingerprint recognition chip 320 and the antenna device 300 can be exposed, and the projection area of the non-metallic shielding opening 80 can cover fingerprints Identify the chip 320 and the antenna device 300.

請繼續參閱圖4B，圖4B為圖4A實施例之剖面圖，將行動裝置外殼50之一非金屬遮蔽開口80預留一空間，露出至少一部分指紋辨識晶片320與天線裝置300之投影位置。非金屬遮蔽開口80之投影面積可涵蓋與天線裝置300相符合之範圍，將指紋辨識晶片320與天線裝置300直接於行動裝置外殼50中露出，可使指紋辨識功能與近場通訊功能之感應能力較快。該導電層311具有一凹孔312，該指紋辨識晶片320嵌設於該凹孔311中而與該電路板310電性相接。 Please continue to refer to FIG. 4B. FIG. 4B is a cross-sectional view of the embodiment in FIG. The projection area of the non-metallic shielding opening 80 can cover the range corresponding to the antenna device 300.

The conductive layer 311 has a concave hole 312, and the fingerprint recognition chip 320 is embedded in the concave hole 311 to be electrically connected to the circuit board 310.

在本實施例中，指紋辨識晶片320採覆晶封裝方式與電路板310電性相接，減少不必要的佔用空間，比起以往傳統之晶片封裝方式，先將晶片置於基板上，再利用打線技術將晶片連接至基板上之連接點，其方式相當費時且費工，而採用覆晶封裝方式，僅需將晶片翻轉後，使凸塊直接與基板連接即可。 In this embodiment, the fingerprint recognition chip 320 is electrically connected to the circuit board 310 in a flip-chip packaging method to reduce unnecessary space occupation. Compared with the traditional chip packaging method in the past, the chip is first placed on the substrate and then used Wire bonding technology connects the chip to the connection points on the substrate, which is very time-consuming and labor-intensive. However, the flip-chip packaging method only needs to flip the chip and connect the bumps directly to the substrate.

請參閱圖5，圖5所繪示為使用者實際操作指紋辨識功能之示意圖，在本實施例中，使用者以左手食指之指紋做為指紋辨識依據，確保使用近場通訊相關功能時，需經由使用者進行指紋辨識，確認該使用者之指紋辨識資訊與行動裝置之資訊相符後，才可授權使用。而在其他實施例中，使用者也能將其他手指或具有皮膚紋路之部位，做為指紋辨識依據。 Please refer to Figure 5. Figure 5 shows a schematic diagram of the user's actual operation of the fingerprint recognition function. In this embodiment, the user uses the fingerprint of the left index finger as the basis for fingerprint recognition to ensure that when using the near field communication related functions, After the user performs fingerprint identification and confirms that the user's fingerprint identification information matches the information of the mobile device, the use can be authorized. In other embodiments, the user can also use other fingers or parts with skin lines as the fingerprint recognition basis.

於習知行動裝置的組裝、維修及更換過程中，天線與指紋辨識晶片是分開裝設，需花費較多的時間。然而，在本實施例中，由於天線裝置、指紋辨識晶 片及電路板是整合在一起的，故在裝上已與指紋辨識晶片電性相接之電路板時也就同時裝設天線裝置，從而縮短組裝所需的時間，進而降低生產成本，且也可使維修過程更為容易，僅需檢查故障原因是否為晶片或電路板即可，無須再一一檢查是否為天線、晶片、電路板及行動裝置等細項檢查，縮減了故障排除與更換零件之時間。另外，在本實施例中，天線裝置所包含之天線為近場通訊天線，故能讓行動裝置使用近場通訊之相關功能。當使用者需使用近場通訊相關功能時，先透過指紋辨識功能進行資料核對，辨識之資訊會經由排線傳輸至行動裝置上，待行動裝置確認完畢後，便授權使用者可使用近場通訊相關功能，例如：電子錢包、電子票卡或與其他人進行檔案傳輸等，除了能夠保障資訊安全，更能避免被有心人士盜用或侵占等不利使用者之行為。此外當進一步將該天線裝置是位於行動裝置外殼之非金屬開口處設計有觸控板時，更能讓使用者在有限之操作空間下，完成多種指令操作。 In the process of assembling, repairing and replacing the conventional mobile device, the antenna and the fingerprint recognition chip are installed separately, which takes a lot of time. However, in this embodiment, due to the antenna device, fingerprint recognition crystal The chip and the circuit board are integrated. Therefore, the antenna device is installed at the same time when the circuit board that has been electrically connected to the fingerprint recognition chip is installed, thereby shortening the time required for assembly, thereby reducing the production cost, and also It can make the repair process easier. It only needs to check whether the cause of the fault is the chip or circuit board. There is no need to check whether it is the antenna, chip, circuit board and mobile device one by one. This reduces troubleshooting and replacement parts. Of time. In addition, in this embodiment, the antenna included in the antenna device is a near field communication antenna, so the mobile device can use the related functions of near field communication. When the user needs to use the near field communication related functions, first check the data through the fingerprint recognition function, and the recognized information will be transmitted to the mobile device via the cable. After the mobile device is confirmed, the user can be authorized to use the near field communication Related functions, such as e-wallets, e-tickets, or file transfers with other people, can not only ensure information security, but also prevent unfavorable user behaviors such as embezzlement or embezzlement by intentional persons. In addition, when the antenna device is further designed with a touch panel at the non-metal opening of the casing of the mobile device, the user can perform a variety of command operations in a limited operating space.
