Problems solved by technology
[0003] However, in the process of manufacturing, shipping and product assembly of printed circuit boards, the solder joints of electronic components on printed circuit boards are often abnormal due to human factors or external factors, which in turn leads to abnormal functions or failures of some circuits
Actual data statistics show that abnormal use of end products due to abnormal soldering of electronic components will consume a lot of manpower and increase process costs

The invention provides a detection circuit suitable for detecting printed circuit boards. The detection circuit at least comprises a power supply device, a plurality of detection components, an early warning component and a plurality of wires, wherein the power supply device is used to supply power to the detection circuit; the detection components are placed in a special area of a printed circuit board respectively in order to detect whether the work of electronic elements in the special area is abnormal; the early warning component is used to send early warning signals when at least one of the detection components detects that the work of the electronic elements is abnormal; and the wires are electrically connected with the power supply device, the detection components and the early warning component. When the detection circuit is adopted, the detection components in the circuit are placed in the special area of the printed circuit board, so circuit abnormalities of the printed circuit board are easy to track and detect in time. In addition, as the detection circuit is independent of function circuits in the printed circuit board, the set control function expected to be achieved by the detection circuit cannot be affected.
Description
Technical field [0001] The present invention relates to a printed circuit board of a liquid crystal television, and in particular to a circuit design for conveniently detecting the printed circuit board. Background technique [0002] In many daily household appliances, the control circuit mainly implements related application functions through a printed circuit board. This printed circuit board not only includes various connectors and electronic components, but also includes a special heat sink for electronic components to dissipate heat. Generally, the fixing of electronic components on the printed circuit board is mostly done by soldering using SMT (Surface Mounted Technology) process or DIP (Dual In-line Package) process. [0003] However, in the process of manufacturing, shipping and product assembly of printed circuit boards, due to human factors or external factors, the solder joints of the electronic components on the printed circuit board are often abnormal, which may lead ...
