Problems solved by technology
[0003] Most of the existing printed circuit boards are fixed by screws, but there is a problem of unstable fixing of the circuit board due to the screw slippery wire. The unstable fixing of the circuit board will easily damage the electronic components on the circuit board and affect the normal use of the circuit board. It is inconvenient to disassemble after slipping, time-consuming and labor-intensive, which affects the work efficiency of the staff

The invention relates to the technical field of printed circuit boards and discloses a printed circuit board manufacturing method and a printed circuit board structure. The PCB manufacturing method includes drawing a circuit diagram, printing the circuit diagram, cutting a copper clad plate, pretreating the copper clad plate, photosensing the circuit board, etching the circuit board, punching thecircuit board and pretreating thecircuit board. S1, drawing circuit diagrams, firstly, drawing the required circuit diagrams on a computer; S2, printing circuit diagrams, and printing the drawn circuit diagrams by a printer. A manufacture method of that printed circuit board and the structure of the printed circuit board, a circuit board is fixed without screws to avoid instability of the circuitboard due to screw slip. At that same time, the circuit board can be guarantee to be normally used, the circuit board is installed and disassembled, time and labor are saved, the working efficiency ofthe staff is improve, the damage of the electronic components on the circuit board under the high-temperature environment can be avoided, and the service life of the circuit board is prolonged, and the like.
Description
technical field [0001] The invention relates to the technical field of printed circuit boards, in particular to a method for manufacturing a printed circuit board and a printed circuit board structure. Background technique [0002] Printed circuit boards, also known as printed circuit boards, are providers of electrical connections for electronic components. Its development has a history of more than 100 years. Its design is mainly layout design. The main advantage of using circuit boards is that it greatly reduces wiring And assembly errors, improve automation level and production labor rate, which can be divided into single-panel, double-panel, four-layer board, six-layer board and other multi-layer circuit boards according to the number of layers. [0003] Most of the existing printed circuit boards are fixed by screws, but there is a problem of unstable fixing of the circuit board due to the screw slippery wire. The unstable fixing of the circuit board will easily damage...
