The present invention changes the original manual welding connector to be the automatic welding connector, the production efficiency is improved, and the welding quality of connectors is improved.
Description
Technical field
The present invention relates on printed circuit board (PCB), mount the technical field of components and parts, especially relate to the process of placing connectors on printed circuit board (PCB).
Background technology
In the surface mount process, on printed circuit board (PCB), need to mount various components and parts.For the common components of no pin, can directly be mounted on the printed circuit board (PCB).For the particular components that pin is arranged, electric connector for example is owing to will insert the pin of connector in the jack on the printed circuit board (PCB), weld again, and required amount of solder paste is more than common components, can't once mount welding with common components, can only be by secondary assembling welding.
In the prior art, on printed circuit board (PCB) the process of mount components and connector as shown in Figure 1, it includes following steps:
(1) ordinary steel reticulated printing solder flux (tin cream), at this moment, does not print at the connector plug jack place;
(2) common components is real is loaded on the printed circuit board (PCB), and common components refers to the element except that connector;
(3) printed circuit board (PCB) Reflow Soldering: in reflow soldering, element is welded on the printed circuit board (PCB), finishes mounting of element;
(4) artificial solder connector.
Above-mentioned process can not disposablely in the surface mount process install connector in fact, can only pass through artificial solder connector when subsequent group is dressed up product.Adopt artificial welding can bring following problems:
(1) compare with mounting common components, the operating efficiency of artificial solder connector is too low;
(2) owing to be artificial welding, in operation process, cause the element that surface mount is good impaired easily at the laggard trip link actuator of surface mount common components;
(3) solder joint of artificial welding formation is more coarse, and size is also not quite identical, and is good inadequately in appearance;
(4) artificial welding needs extra welding personnel, and welding bench and working area have increased cost.
Summary of the invention
The present invention is directed to the above-mentioned common components that mounts the method inefficiency of the printed circuit board (PCB) that has connector and mount and be easy to impaired problem, provide a kind of high efficiency, welding quality the good process of placing connectors on printed circuit board (PCB).
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
The process of placing connectors on printed circuit board (PCB) may further comprise the steps:
(1) the jack place of placing connectors adopts the steel mesh print solder paste of being with the steel mouth on printed circuit board (PCB);
(2) on printed circuit board (PCB), mount the common components place and adopt ordinary steel reticulated printing tin cream;
(3) real dress common components on printed circuit board (PCB);
(4) real add-in connectors on printed circuit board (PCB) is in the jack on the pin insertion printed circuit board (PCB) of connector;
(5) printed circuit board (PCB) that will finish (3), (4) step is inserted and is carried out reflow soldering in the reflow soldering furnace, finishes mounting of connector.
Technique effect of the present invention is: compare with the process of prior art, the present invention has increased by two steps:
The one, the steel mesh that has increased band steel mouth prints this specific step.In this step, adopt the steel mesh of special band steel mouth that paste solder printing is carried out at the jack position of connector on printed circuit board (PCB), so that connector is carried out reality dress and reflow soldering, thus replace artificial welding.
The 2nd, increased the real dress step of connector on printed circuit board (PCB), so that connector is carried out reflow soldering.
The present invention has cancelled artificial solder connector step of the prior art, and connector is entered the reflow soldering welding with common components, changes automatic welding into by original artificial solder connector, has improved production efficiency, has improved the welding quality of connector.The present invention need not extra welding personnel and equipment, has reduced cost.
