Problems solved by technology
The existing circuit boards only allow a single connection to the circuit, and do not have two circuits to be connected to the circuit after splicing, so the capacity of the circuit board cannot be increased. At the same time, the existing circuit board does not have the function of folding. It is more troublesome, so it is necessary to design an in-line expansion circuit board for digital TV

Description
technical field [0001] The invention relates to the technical field of circuit board equipment, in particular to an in-line extended circuit board for digital television. Background technique [0002] The circuit board is the most active industry in the contemporary electronic component industry, mainly composed of pads, vias, mounting holes, wires, components, connectors, fillings, electrical boundaries, etc. The existing circuit boards only allow a single connection to the circuit, and do not have two circuits to be connected to the circuit after splicing, so the capacity of the circuit board cannot be increased. At the same time, the existing circuit board does not have the function of folding. It is troublesome, so it is necessary to design an in-line expansion circuit board for digital TV. Contents of the invention [0003] The object of the present invention is to provide an in-line extended circuit board for digital TV, so as to solve the problems raised in the abo...
