Specific embodiment
Below by specific embodiment and combine accompanying drawing the application is described in further detail.
With reference to Fig. 1, the embodiment of the present application provides a kind of steel mesh, this steel mesh include for printed circuit board on welding
The corresponding Part I in position 10 and for the Part II 20 corresponding with the non-solder position on printed circuit board, first
Steel mesh mouth 100 is opened up on part 10, Part II is solid platy structure.
Welding position on printed circuit board refers to need the position of welding electronic component on printed circuit board, and first
Part 10 is used at tin cream movement to this position, in order to welding electronic component；Non-solder position on printed circuit board
Refer to the position of welding electronic component is not needed on printed circuit board.
Above-mentioned steel mesh will be set to solid platy structure with the corresponding Part II in non-solder position 20 of printed circuit board,
That is, not opening steel mesh mouth on this Part II 20 so that tin cream is not easy to flow to does not need welding electronic component
Position, also would not lead to the problem that losing efficacy occur in electronic devices and components.Therefore, this steel mesh can improve the reliability of electronic devices and components
Property.
The steel mesh that the embodiment of the present application provides can apply in the welding procedure of multiple electronic devices and components, specifically, should
Steel mesh can apply in the welding procedure of board to board connector as shown in Figure 3 and Figure 4, and now, this steel mesh still includes using
In the Part I 10 corresponding with the welding position on printed circuit board and for and printed circuit board on non-solder position
Corresponding Part II 20, Part I 10 opens up steel mesh mouth 100, and Part II 20 is solid platy structure.
Due to multiple parts being provided with board to board connector, but combine practical situation, most board to board connectors
Welding procedure relates generally to the welding of signal pin 30.Therefore, above-mentioned Part I 10 can be used for and the plate on printed circuit board
Corresponding to connector for substrate signal pin welding position, this board to board connector signal pin welding position refers to printing electricity
It is used on the plate of road welding the position of the signal pin 30 of board to board connector.This kind of structure makes the steel that the embodiment of the present application provides
Net can apply to weld the signal pin 30 of board to board connector.
Size generally ratio in view of the corresponding pad of above-mentioned board to board connector is larger, therefore in order to prevent welded plate pair
During connector for substrate, flow to the tin cream on pad excessively it is necessary to make the overall size of steel mesh mouth 100 be less than board to board connector
The overall size of signal pin (i.e. the signal pin 30 of board to board connector).Overall size herein refers to the chi of outline
Very little, such as, when steel mesh mouth 100 and signal pin 30 are all using rectangular configuration, what this overall size referred to is exactly length and width.
Further, the quantity of this steel mesh mouth 100 is multiple, and the number of the quantity of steel mesh mouth 100 and board to board connector signal pin
Amount is equal, completes the movement of more tin creams after the mobile steel mesh of single with this, then improves the assembling effect of board to board connector
Rate.
Welding due to there being some board to board connectors can be related to the welding of signal pin and fixing pin simultaneously, therefore
Above-mentioned Part I 10 is used for and the board to board connector signal pin welding position on printed circuit board and board to board connector
Fixing pin welding position is corresponding.This board to board connector fixing pin welding position, refers to be used on printed circuit board
The position of the fixing pin 40 of welding board to board connector.By this kind of structure it is possible to process board to board connector simultaneously
Signal pin 30 and fixing pin 40, improve the packaging efficiency of board to board connector then to a greater degree.
Specifically, as shown in Fig. 2 aforementioned steel mesh mouth 100 can be included for corresponding with board to board connector signal pin
The first steel mesh mouth 100a, and for and board to board connector fixing pin (i.e. the fixing pin 40 of board to board connector) phase
Corresponding second steel mesh mouth 100b.Further, the overall size of this first steel mesh mouth 100a is less than board to board connector signal
The overall size of pin, prevents the tin cream flowing on pad by the first steel mesh mouth 100a excessive with this.In the same manner, the second steel mesh
The overall size of mouth 100b is less than the overall size of board to board connector fixing pin.
In a kind of embodiment, the quantity of the first steel mesh mouth 100a is multiple, and the quantity of this first steel mesh mouth 100a and plate
Equal to the quantity of connector for substrate signal pin, the corresponding welding position of each signal pin is moved in single process with this simultaneously
The tin cream at place, to lift the packaging efficiency of board to board connector.In the same manner, the quantity of the second steel mesh mouth 100b can also be arranged
For multiple, and the quantity of the second steel mesh mouth 100b is equal with the quantity of board to board connector fixing pin.
Foregoing embodiments provide the steel mesh being only used for the signal pin 30 welding board to board connector, and also providing can
For welding the signal pin 30 of board to board connector and the steel mesh of fixing pin 40 simultaneously, the steel mesh of these different structures is in tool
Body has replaceability during using.Therefore, it is possible to according to plate pair after the specification of board to board connector changes
The situation of change of the signal pin 30 in connector for substrate and fixing pin 40 flexibly selects corresponding steel mesh.
And pad then can adopt the pad of unified structure, its structure can be as shown in figure 5, consider all size
The structure change of board to board connector after the structure of pad is set, this pad may include the first pad 50 and the second pad
60, the first pad 50 is used for welding signal pin 30, and the second pad 60 is used for being welded and fixed pin, meets all size with this
The welding requirements of board to board connector.Pad is set to unified structure, can be managed in order to butt welding disk.
The foregoing is only the preferred embodiment of the application, be not limited to the application, for the skill of this area
For art personnel, the application can have various modifications and variations.All within spirit herein and principle, made any repair
Change, equivalent, improvement etc., should be included within the protection domain of the application.
