The invention belongs to the technical field of circuit boards, in particular relating to a mounting method for a circuit board. The mounting method for the circuit board includes the following steps:providing a mounting production line and a plurality of jigs, wherein the mounting production line includes a mounter and a reflow oven, and first accommodating grooves and second accommodating groove are arranged on the jigs; placing, in the first accommodating grooves, a first batch of first circuit boards with bottoms mounted; performing mounting and reflowing; repeating the placing step untilonly the top surfaces of the last batch of second circuit boards haven't finished mounting and reflowing; and placing, on the mounting production line, second circuit boards that haven't finished mounting and reflowing to complete mounting and reflowing, thus mounting and reflowing of all circuit boards are completed. The mounting method for the circuit board of the invention improves the utilization efficiency of the production line, reduces printed circuit board assembly (PCBA) oxidation caused by a long time interval between passage of top surfaces through an furnace and production of thetop surfaces, thus the production cost is reduced, the time for line change is reduced, and product quality can be monitored in real time.
Description
technical field [0001] The invention belongs to the technical field of circuit boards, in particular to a mounting method for circuit boards. Background technique [0002] SMT is Surface Mount Technology (SMT), also known as surface mount or surface mount technology, which is currently the most popular technology and process in the electronics assembly industry. In the whole production process of SMT, the PCB board is the main material. The PCB board is divided into single-panel and double-panel, and the double-panel is divided into Top and Bottom. There are many components on the top surface (such as BGA, QFP, etc.) that have high temperature requirements and cannot pass through the secondary furnace. Only the bottom surface is produced first, and then the top surface is produced by switching lines. Moreover, the lack of Bottom components will seriously affect the use efficiency of the production line, resulting in higher production costs, and can reduce the PCBA oxidation...
