The utility model discloses a having the pad of L shape through -hole, can all covering the backlight unit trade, its depth of parallelism is guaranteed to the position of correction components and parts that can be accurate. Has the technique of the pad of L shape through -hole, SMT chip mounter that the cooperation is upgraded, batch volume production that equally can the high yield of high efficiency.
Description
Technical field
This utility model relates to the Welding Structure of components and parts, particularly to one for backlight module
The pad structure of components and parts welding location.
Background technology
The welding procedure of components and parts, is commonly called as SMT paster, and automatic placement machine passes through optical registration point
Look for welding position paster, it is clear that during SMT paster, paster and pressure can be there is
The factor such as not, after paster is complete, during crossing Reflow Soldering, components and parts will off normal or
Rosin joint, thus can bring the personnel of reprocessing substantial amounts of workload, and exist reprocess after bad
Hidden danger.
The structure of the pad 1 at welding position as shown in Figure 1, the pad of components and parts is L-shaped,
But the through hole of pad 1 is belonging to square, result in the process that components and parts solidify in Reflow Soldering
In create off normal.
Utility model content
The purpose of this utility model is the drawbacks described above for prior art, it is provided that a kind of structure letter
When list, rectifiable SMT paster, produced off normal positions for the welding of backlight module components and parts
Pad structure.
For solving the drawbacks described above of prior art, the technical scheme that this utility model provides is: one
Plant the pad structure for backlight module components and parts welding location, use including components and parts welding position
Pad and coordinate with this pad correct components and parts off normal components and parts pad, described pad sets
There is the through hole identical with described components and parts bond pad shapes.
As this utility model pad structure for backlight module components and parts welding location one
Planting and improve, the shape of described through hole is the most L-shaped with the shape of described components and parts pad.
As this utility model pad structure for backlight module components and parts welding location one
Kind improving, described components and parts pad is arranged on one can carry multiple components and parts pad can
On the base changed.
As this utility model pad structure for backlight module components and parts welding location one
Planting and improve, the both sides of the edge of described base are equipped with the groove of a concave downward, described unit device
One right-angle side of part pad inserts in described groove.
As this utility model pad structure for backlight module components and parts welding location one
Planting and improve, the face height of another right-angle side of described components and parts pad is less than described base
Upper surface height.
Compared with prior art, the utility model has the advantages that: this utility model uses has L
The pad of shape through hole, can all contain backlight module industry, can correct components and parts accurately
Position, it is ensured that its depth of parallelism.There is the technology of the pad of L-shaped through hole, coordinate upgrading
Large quantities of volume productions of SMT chip mounter, equally high efficiency height yield.
The pad of square through hole changes to the pad of L-shaped through hole, and the pad of L-shaped through hole corrects unit
The off normal of device, carrier FPC and components and parts pad can be adequately exposed to, it is ensured that finished product goes out
Goods does not haves the bad phenomenon such as rosin joint, dry joint.This utility model also has raising components and parts
The depth of parallelism, reduce artificial, cost-effective, improve the advantage such as yield.
Accompanying drawing explanation
The most with reference to the accompanying drawings with detailed description of the invention to this utility model and useful technology thereof
Effect is described in further detail, wherein:
Fig. 1 is the structural representation of the pad in prior art at welding position.
Fig. 2 is the structural representation of the pad in this utility model at welding position.
Fig. 3 is this utility model components and parts pad modular construction schematic diagram.
Reference title: 1, pad 2, components and parts pad 3, through hole 4, base 5,
Groove.
Detailed description of the invention
With specific embodiment, this utility model is further described the most with reference to the accompanying drawings, but this
The embodiment of utility model is not limited to this.
As shown in Figures 2 and 3, a kind of pad knot for backlight module components and parts welding location
Structure, including the pad 1 of components and parts welding position and coordinate with this pad 1 rectification components and parts inclined
The components and parts pad 2 of position, pad 1 is provided with the through hole 3 identical with components and parts pad 2 shape.
Preferably, the shape of through hole 3 is the most L-shaped with the shape of components and parts pad 2.
Preferably, components and parts pad 2 be arranged on one can carry multiple components and parts pad 2,
And on removable base 4.
Preferably, the both sides of the edge of base 4 are equipped with the groove 5 of a concave downward, unit's device
One right-angle side of part pad 2 inserts in groove 5.
Preferably, the face height of another right-angle side of components and parts pad 2 is less than base 4
Upper surface height.
This utility model uses the pad 1 with L-shaped through hole, can all contain backlight module
Industry, can correct the position of components and parts, it is ensured that its depth of parallelism accurately.There is L-shaped through hole
The technology of pad 1, coordinate the SMT chip mounter of upgrading, equally high efficiency height yield
Large quantities of volume productions.
The pad of square through hole changes to the pad 1 of L-shaped through hole, and the pad 1 of L-shaped through hole is rectified
The off normal of positive components and parts, carrier FPC and components and parts pad 2 can be adequately exposed to, it is ensured that
Finished product shipment does not haves the bad phenomenon such as rosin joint, dry joint.This utility model also has raising unit
The depth of parallelism of device, reduce artificial, cost-effective, improve the advantages such as yield.
Embodiment the most of the present utility model, common for this area
For technical staff, it is possible to understand that in the case of without departing from principle of the present utility model and structure
These embodiments can be carried out multiple change, revise, replace and modification, of the present utility model
