Abstract
The method includes following steps: providing first element with hole on it; providing second element with soldering pad on it; providing a fixed part movable in the said hole up and down; inserting the fixed part into hole, and setting up it on surface of second element, one end of fixed part corresponded with soldering pad on second element; welding fixed part with soldering pad. The method keeps good planeness between fixed part and second element, and stabilized connection.
Description
[technical field]
The present invention relates to the fixing means between a kind of element, refer in particular to the fixing means between a kind of elements on circuit board.
[background technology]
On circuit board, two elements are fixed together, multiple modes such as bolt and nut connection, welding are arranged usually.The bolt and nut attended operation is loaded down with trivial details, and it is more to take up room, and quality is bigger, so seldom adopt at present.Multiple advantages such as that welding has is easy to operate, little, the light weight of taking up room, but be welded with a problem that is always perplexing the technical staff: Coplanarity Problems.Because if a plurality of pad coplanarities are bad, then may cause certain pad failure welding, even cause empty weldering, thereby have a strong impact on fixed effect.
[summary of the invention]
The object of the present invention is to provide the fixing means between a kind of element, it can influence failure welding, to guarantee good fixed effect.
Fixing means between the element of the present invention, it may further comprise the steps:
First element is provided, which is provided with hole;
Second element is provided, and this second element is a circuit board, which is provided with weld pad;
One fixture is provided, and described fixture comprises the main part of a size less than hole, and this main part one end is provided with the boss of size greater than hole, and its other end also is provided with a protuberance, and this fixture integral body can relatively move with described hole;
Fixture is inserted in the hole, and they are placed on the surface of second element, fixture one end is corresponding with the weld pad on the circuit board;
Fixture and weld pad are welded together.
Because of fixture can move at the above-below direction of the hole on first element, make the fixture and second element keep flatness preferably, connection simultaneously is comparatively stable, has guaranteed between the two elements fixedly connected preferably.

[embodiment]
The present invention is further illustrated below in conjunction with drawings and Examples.
Shown in Fig. 1 to 4, the fixing means between a kind of element provided by the present invention, it may further comprise the steps:
(1) (at present embodiment is an electric connector to provide first element 1, also can be elements such as radiator), it comprises insulating body 10 and is located at conducting terminal inside (not drawing among the figure), projection 13 outwards is equipped with in four corners of insulating body 10, each projection 13 is provided with hole 11, and hole 11 madial wall bottoms are provided with projection 12;
(2) provide second element 2 (being a circuit board in the present embodiment), its upper surface is provided with weld pad 20;
(3) provide a fixture 3, it comprise a size less than the main part 30 of hole 11 and be positioned at main part 30 1 ends and size greater than the boss 32 of hole 11, this boss 32 is positioned at main part 30 upper ends in the present embodiment.This main part lower end is provided with a protuberance 300, and this protuberance 300 can be held in set projection 12 on first element, 1 corresponding surface (not drawing among the figure) or hole 11 madial walls.These main part 30 lower ends can be welded mutually with weld pad 20.Boss 32 ends can combine other element it with bolt or screw fit to having screwed hole 33 with electric connector;
(4) fixture 3 is penetrated from top to bottom in the hole 11 of first element 1, and they are placed on the upper surface of second element 2, fixture 3 lower ends are corresponding with the weld pad 20 on second element 2;
(5) fixture 3 and weld pad 20 are welded together.
Figure 5 shows that second kind of embodiment of the present invention, be that with the difference of the foregoing description boss is positioned at the main part lower end in the present embodiment, and the main part upper end is provided with protuberance, this protuberance can be held in the upper surface of the first element correspondence.
Figure 6 shows that the third embodiment of the present invention, be with the difference of first kind of embodiment, the lower surface of the weld part 31 ' of fixture 3 ' is provided with tin ball 4 ' in the present embodiment, so that when weld pad with second element is matched, be easy to control its flatness, required tin amount when increasing welding simultaneously, make have between two electronic components fixedly connected preferably.
With reference to Fig. 7, among the present invention, needed fixture 3 " weld part 31 " lower surface also can extend to form guidance part 34 downwards "; second element is provided with hole; guidance part 33 " can insert in the hole on second element, better and between second element to position, increase connective stability.
The size of mount body portion is less than the size of hole or groove, make fixture to move up at the upper and lower of the hole on first element, make the fixture and second element keep flatness preferably, connection simultaneously is comparatively stable, has guaranteed between the two elements fixedly connected preferably.
