Integrated Components
The Vivo Y33s sub-board is a multi-functional PCB layout. When you buy a replacement flex strip, it typically hosts the following components pre-soldered onto it:
- USB Type-C Dock Port: The main input jack where your Type-C cable plugs in to handle 18W Fast Charging and high-speed data transfer.
- Primary Microphone (Mic): The voice receiver module responsible for your audio during phone calls and voice recordings.
- Headphone Jack Connector: The terminal interface that connects the lower daughterboard to your phone’s physical handsfree audio output.
- Antenna Signal Terminals: Metallic contact points that anchor the RF coaxial cable to ensure stable cellular network and Wi-Fi reception.
- Buzzer/Ringer Spring Contacts: Gold-plated surface points that make structural contact with the loudspeaker module to power audio playback.
