The invention discloses a method for improving PCB antenna insertion and welding accuracy, comprising the following steps: S1, making a special tray, and fixing the PCB board on the special tray; S2, performing automatic insertion of the antenna through an SMT placement machine Install, insert the antenna into the mounting hole on the PCB; S3, make a cover device to cover the antenna, and limit the angle of the antenna to ensure that the tilt angle of the antenna on the PCB meets the requirements of 0°±5° ; S4, the antenna is soldered through selective wave crests. In the present invention, the antenna adopts the new technology of SMT automatic plug-in and selective wave soldering, which can be flexibly applied to other types of through-hole plug-in components on PCB boards that require plug-ins, which can not only greatly improve SMT production efficiency, but also maximize Reducing welding voids and less tin defects ensures very stable welding quality, which has the advantages of high production efficiency, cost saving and high welding quality.
Description
technical field [0001] The invention mainly relates to the technical field of PCB boards, in particular to a method for improving the precision of PCB antenna insertion and welding. Background technique [0002] For the insertion and welding process of through-hole insertion components and antennas, the original process flow is: PCB (Printed Circuit Board, printed circuit board) front and back sticky board → PCB front and back solder pad printing solder paste → manual insertion of antenna → antenna Reflow soldering. Since the position of the PCB antenna pad requires double-sided printing of solder paste, and then manually inserts the antenna and then passes the antenna through the reflow furnace to realize antenna reflow soldering, this printing solder paste reflow soldering process has the following four disadvantages: [0003] a. Because the antennas are inserted manually, it is necessary to place the antennas into the PCB holes one by one with tweezers, which is extremel...
