Abstract
The utility model discloses a printed circuit board connection structure. The connection structure comprises a printed circuit board PCB1, a printed circuit board PCB2, spacers, and fasteners for connecting or conducting two circuit boards. The printed circuit board PCB1 is provided with metalized through holes, the lower surface of the printed circuit board PCB1 is provided with metal pads around the metalized through holes, and a layer of soldering paste is printed onto the metal pads. According to the utility model, through the structure improvement of the connection between the printed circuit boards and the spacers, a layer of soldering paste is printed onto the metal pads, and a certain gap exists around the spacers and the metalized through holes, so the manual soldering method in which a soldering iron is used can be replaced with a reflow soldering machine, so that the semi-automatic soldering of the printed circuit boards is realized, the production efficiency is improved, and the product quality is well ensured.
Description
Technical field
The utility model belongs to electronic technology field, relates to a kind of connection structure of printed wiring board.
Background technology
In current electron trade, printed substrate is almost ubiquitous, little of electronic watch, calculator, general-purpose computer, large to computer, communication electronic equipment, Aeronautics and Astronautics, military armament systems, as long as the electronic devices and components such as integrated circuit are arranged, electric interconnection all will be used printed substrate between them.The production process of printed substrate is comparatively complicated, the processing range that it relates to is wider, for connection structure of printed wiring board, being connected between traditional printed substrate and the spacer mainly is to adopt direct welding manner, spacer is inserted in the printed substrate, weld by manual flatiron, this connected mode production efficiency is low, and quality is without guarantee, because the production process of printed substrate is a kind of discrete streamline form, any one link goes wrong all can cause the consequence that completely stops production or scrap in a large number, and if printed substrate scrap just can't recycling.Therefore how to improve the production efficiency of printed substrate, quality is protected, the rate of reducing the number of rejects and seconds is electron trade department problem demanding prompt solution.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of connection structure of printed wiring board is provided.
The utility model is achieved by following technical solution.
A kind of connection structure of printed wiring board, comprise that printed substrate PCB1, printed substrate PCB2, spacer reach the securing member that is used for connection or two wiring boards of conducting, described printed substrate PCB1 is provided with the metallization via hole, be provided with metal pad in printed substrate PCB1 upper and lower surface by metallization via hole periphery, at metal pad printing one deck solder(ing) paste.
Be provided with the gap around the metallization via hole of described spacer insertion end and printed substrate PCB1, when being convenient to weld, make solder(ing) paste flow to gap location, spacer is able to firm the connection with printed substrate PCB1 after the cooling.
Be threaded installing hole in the described spacer, outer surface is zinc-plated.
Described securing member for connection or two wiring boards of conducting adopts screw, and is simple in structure, easy to operate.
Compared with prior art, the beneficial effects of the utility model are: the architecture advances between the utility model connects by printed substrate and spacer, at metal pad printing one deck solder(ing) paste, and leave certain interval at spacer and metallization via hole periphery, can adopt reflow machine to replace manual flatiron welding, realization is welded the semi-automation of printed substrate, thereby enhances productivity, and product quality obtains fine guarantee.
