The mobile phone antenna acts as a bridge for communication of wireless communication devices, and plays the role of transmitting and receiving radio frequency signals. If the mobile phone does not have an antenna, all wireless communication functions of the mobile phone will be disabled. The quality of mobile phone antenna design is directly related to the performance of mobile phone calls, data communications and other services. With the development of mobile phone functions and ultra-thinness, it poses higher challenges for the design of mobile phone antennas. Generally, In order to ensure the ID shape of the mobile phone, some mobile phone manufacturers will choose to sacrifice some antenna performance as a price.
Most of the so-called ultra-thin smart phones on the market have adopted a raised design. That is to ensure the performance of the antenna and audio. But the Finder has done it. With the same thin body, the antenna and audio performance are as good as ever. So what advanced technology and innovative methods does the Finder use to accomplish all of these antennas and audio?
The main antenna adopts the industry-leading integrated design of the antenna bracket and the audio box (AUDIO BOX) (this process is only used by Apple and OPPO in the currently available mobile phones), the original three-dimensional antenna pattern design + laser engraving (LDS) The realization of the process guarantees the excellent performance of the antenna, making its antenna performance completely no less than 10mm or thicker models.

The sound cavity structure adopts OPPO patented technology --- integrated BOX design (three-in-one design of speaker, sound cavity and antenna) integrated BOX design, using OPPO's own patented technology (already applied), effectively improving the mobile phone in thin In a small space, the volume of the speaker's vibration space is maximized, so that the bass is stable and powerful, heavy and not turbid, and the midrange is bright and prominent, full and full without being stiff.
CRCBOND195561 series of high-strength plastic-bonded UV glue provides important contributions to the sound cavity integrated antenna module. CRCBOND195561 has super strong adhesion to PC, ABS, PPA, and nylon glass fiber. The colloid itself has a compact structure and high cohesion. The meter performed excellently in the vertical drop test of cement or steel plate, reaching 48 times without degumming and cracking, and has a rigorous anti-rollover test, and the 6590 test reached 144 hours.
CRCBOND195561UV basic characteristics:
Color: transparent, dark blue, fluorescent red, light black, etc. Non-standard production viscosity: 3000-30000cps, choose a variety of viscosity according to the actual application hardness: A60, D50, D65 and other multi-hardness selection adhesive force: 20-45N
With CCD fluorescence inspection.
Suitable for manual dispensing, semi-automatic dispenser, automatic dispenser dispensing, FISHING jet dispensing.
