Description
Technical field
The present invention relates to a kind of production methods of welding resistance windowing concentricity at promotion acoustic aperture and acoustic aperture.
Background technique
Requirement with people to electronic product quality with the development of electronic technology, more and more product requirement acoustic aperture hole
Diameter and acoustic aperture welding resistance concentricity are less than 0.05mm.The process of such product is：... → drilling → heavy copper → plating → route →
Anti-welding →... ....The influence factor of such product concentricity has：Borehole accuracy tolerance+0.035, route are relative to the same of drilling
Concentricity ± the 0.035mm of heart degree ± 0.035, welding resistance relative to route is so as to cause accumulated toleranceIt is low for the product yield within position degree requirement ± 0.05mm, and select
Labor intensive, goods and materials cause the higher of cost of manufacture
Summary of the invention
In order to overcome drawbacks described above, the present invention provides a kind of production of welding resistance windowing concentricity at promotion acoustic aperture and acoustic aperture
Method can improve the yield of solder mask window concentricity and raising product at acoustic aperture and acoustic aperture.
The present invention is to solve technical solution used by its technical problem：A kind of promotion acoustic aperture is opened with welding resistance at acoustic aperture
The production method of window concentricity, including the semi-finished product for making acoustic aperture, the semi-finished product intermediate region forms shaping area, and
Peripheral regions form non-forming area, bore four too in the non-forming area while acoustic aperture is bored in the shaping area of half product
Positive hole, each sun hole is located at the aperture in same great circle by several centers of circle and forms, and the size of the aperture and the acoustic aperture
It is identical.
As a further improvement of the present invention, each sun hole includes eight apertures identical with acoustic aperture size, and is used
It is same that brill nozzle is drilled through.
As a further improvement of the present invention, four sun holes are located at four angles in the non-forming area, and one of them
Three sun hole sites in sun hole site and other are asymmetric.
The beneficial effects of the invention are as follows：The promotion acoustic aperture at acoustic aperture welding resistance windowing concentricity production method by boring
4 groups of sun holes by 8 keyhole formations are drilled through using the same brill nozzle with acoustic aperture while hole makes acoustic aperture, as acoustic aperture and sound
The aligning structure of welding resistance windowing concentricity, greatly improves concentricity (< 0.05mm) of the acoustic aperture with respect to solder mask window, with full at hole
Sufficient concentricity or the tighter product demand of tolerance.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the structural schematic diagram in the sun hole.
In conjunction with attached drawing, make the following instructions：
1 --- semi-finished product；2 --- shaping area；
3 --- non-forming area；4 --- sun hole；
5 --- aperture.
Specific embodiment
Below in conjunction with attached drawing, elaborate to a preferred embodiment of the invention.But protection scope of the present invention is not
Be limited to following embodiments, i.e., in every case with simple equivalence changes made by scope of the present invention patent and description with repair
Decorations, all still belong within the invention patent covering scope.
It refering to fig. 1-2, is a kind of production method for promoting welding resistance windowing concentricity at acoustic aperture and acoustic aperture of the present invention,
Including the semi-finished product 1 for making acoustic aperture, the semi-finished product intermediate region forms shaping area 2 and peripheral regions formed it is non-at
Four sun holes 4, each sun bore in the non-forming area while boring acoustic aperture in the shaping area of half product in type area 3
Hole is located at the aperture 5 in same great circle by several centers of circle and forms, and the aperture is identical as the size of the acoustic aperture.Each sun
Aperture arrangement on hole can be symmetrically or asymmetric, but need to guarantee that its center of circle is located on the same circle.
Preferably, each sun hole includes eight apertures identical with acoustic aperture size, and brill nozzle is drilled through using same, is protected
Card small aperture is consistent with acoustic aperture aperture, and same brill nozzle, position degree deviation amount can almost be ignored；Four sun holes are located at institute
Four angles in non-forming area are stated, and three sun hole sites in one of sun hole site and other are asymmetric, that is, form fool proof,
Convenient for contraposition difference.
In this way, the contraposition when making pattern transfer, in the center of circle and data of the great circle of each aperture center of circle composition in sun hole
The hole center of circle is matched, and the offset of hole location is avoided, when line pattern contraposition exposes, the offset of device to hole when graph exposure
Amount is preferably minimized, and figure aligns offset：≤0.035mm.Anti-welding figure contraposition is aligned using this sun hole, and concentricity control ±
0.035mm, and the accumulated tolerance for route and acoustic aperture anti-welding at this time isIt also protects simultaneously
Other sizes tolerance is demonstrate,proved within ± 0.05mm.
It can be seen that the production method of welding resistance windowing concentricity is by making acoustic aperture in drilling at the promotion acoustic aperture and acoustic aperture
While 4 groups of sun holes by 8 keyhole formations are drilled through using the same brill nozzle with acoustic aperture, opened as acoustic aperture and welding resistance at acoustic aperture
The aligning structure of window concentricity greatly improves concentricity (< 0.05mm) of the acoustic aperture with respect to solder mask window, with meet concentricity or
The tighter product demand of tolerance.
