The invention discloses a production method of a printed circuit board. Firstly, a feeding rack is obtained. The feeding rack includes a main board assembly and an auxiliary board assembly, and side frames arranged symmetrically on both sides of the main board assembly. The crossbeam is installed on the main board assembly through vertical columns; the auxiliary board assembly is installed on the beams of the two side frames; the opposite side of the main board assembly and the auxiliary board assembly has a plate groove; Installed at the two corners of the main board assembly; the two beams also have a linear guide mechanism arranged along the length direction, and the two sides of the auxiliary board assembly in the length direction have coaxially arranged rotating shafts, and are rotatably connected to the linear guide through the rotating shaft. On the moving part of the mechanism; both sides in the length direction of the auxiliary plate assembly have at least one locking piece for detachably fixedly connecting the beam or the column. The invention has the advantages of convenient operation, reduced labor intensity, and improved production efficiency of printed circuit boards.
Description
technical field [0001] The invention relates to the technical field of integrated circuit board production and manufacturing, in particular to a production method of a printed circuit board. Background technique [0002] The printed circuit board is mainly responsible for providing the wiring circuit for the electrical connection of electronic components. The manufacturing process of the printed circuit board includes multiple processes. Due to the large number of electronic components soldered on the printed circuit board and their different characteristics, the electronic components need to be soldered in batches , In order to ensure the consistency of welding quality, automatic welding equipment is usually used to complete the placement and welding of electronic components, and the printed circuit board is transported to the automatic welding equipment through a conveyor belt. At present, in order to automatically load the printed circuit boards onto the conveyor belt, th...
