There are some PCB boards in a TV? How is it produced?

In addition to the screen, the performance of an LCD TV may be most affected by how the PCB board it uses is designed and produced. The PCB manufacturer briefly introduces the relevant information of the TV PCB board. For most TVs, the PCB board is mainly divided into the following parts:

1. First of all, it is the TV motherboard. A good TV is absolutely inseparable from a good motherboard, and the motherboard generally integrates the central processing unit (CPU), memory, display core, memory and other types of chips, capacitors, and circuits. Wait

2. Next is the T-CON board, whose function is to control the sequence of the LVDS digital signal sent by the main board in the logic board and convert the row and column drive digital signals required by the glass substrate of the LCD screen to drive the LCD screen to display images.

3. The LED board and the KEY board, these two are also sub-boards, which are mainly used on the remote control to display colors and let the keys work. The manufacturing of these types of PCB boards is mainly done through SMT. In the SMT production process, a complete production process is carried out through the steps of solder paste printing, device mounting, and reflow curing.

In the SMT production process, it is necessary to strictly control the quality of the PCB finished board, because any small defect will affect the performance of the whole machine, and even cause serious problems of not booting.

Before a TV goes on the market, small batches of trial production will be conducted, ranging from 2 to 4 times. In these trial production processes, it is actually the confirmation of the integration of design and production technology, that is, the design proposal proposed by the development department., Can it be produced by the production department?

The design is too radical, and the craftsmanship of the production department cannot meet the requirements. This is not a good design. Therefore, in the PCB board development and design process, there are various compromises.
For example, the compromise of production equipment parameters for the SMT production department, and for the production department, is full of various innovations, such as the transformation of equipment to meet the design requirements. A good product is actually whether the manufacturer can synchronize design and manufacturing, and jointly achieve innovative products!
