However, since the thickness of the motherboard of the TV is much thicker than that of the mobile device, and its thickness is usually between 1.2mm and 1.6mm, the laser hole process will not be applicable when setting the USB-C terminal on the motherboard of the TV , it is necessary to use the traditional drilling process to process the via hole
However, the via hole is processed by the drilling process, and the size of the via hole is relatively large. Usually, the diameter of the via hole is 0.25mm, and the size of the pad of the via hole can reach 0.46mm. In the way of USB-C terminal, the second row of pins of the USB-C terminal is drilled in the gap between the first row of pads and the second row of pads on the motherboard of the TV. connect

The invention provides a circuit board used for a TV and a TV. The circuit board used for the TV comprises a USB-C terminal. The power supply pin B4 and the power supply pin A9 of the USB-C terminal are connected together by a first wire of a printed circuit board. The power supply pin B9 and the power supply pin A4 of the USB-C terminal are connected together by the second wire of the printed circuit board. The grounding pin B1 and the grounding pin A12 of the USB-C terminal are connected together by the third wire of the printed circuit board. The grounding pin B12 of the USB-C terminal is connected with the grounding wire of the circuit board by a first through hole. The high speed signal pin B2 and the high speed signal pin B3 of the USB-C terminal, the high speed signal pin B6 and the high speed signal pin B7 of the USB-C terminal are respectively connected with a processor by through holes disposed between bonding pads corresponding to a first row of pins and bonding pads corresponding to a second row of pins, and therefore the arrangement of the USB-C terminal in the TV is realized.
Description
technical field [0001] Embodiments of the present invention relate to electronic technology, and in particular to a circuit board used in a TV and the TV. Background technique [0002] Universal Serial Bus (USB for short) is a serial bus standard that connects hosts and external devices, and is also a technical specification for input and output interfaces. The host can be computers, mobile devices, televisions, and photographic equipment , game consoles, etc. The USB interface supports hot plug (Hot plug) and plug and play (Device Plug and Play, referred to as PnP). With the continuous development of USB technology, USB 3.1 is the latest USB specification, and its data transmission speed can be increased to 10Gbps. Compared with USB 3.0, USB 3.1 uses a more efficient data encoding system and provides more than double the effective data Throughput rate. [0003] Among them, USB-C (USB Type-C) is a new interface model produced along with the USB 3.1 standard. figure 1 In ...
