Description
Technical field
It the utility model is related to wiring board technology field, more particularly to a kind of charging head wiring board.
Background technology
USB class charging heads are the mainstream configuration of all electronic equipment chargings at present, application and industry-by-industry, as the equipment
Main devices, the quality quality of wiring board directly affects properties of product.Existing market charging head wiring board because product in itself
It is thin, small, hole position intensive nature, manufacture difficulty is very high, causes product can not meet the quality requirements via of follow-up finished product production
Beat and metal is done on pad or resin plug hole design cost is higher.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, there is provided a kind of charging head wiring board, to lift PCB
Appearance, reduce PCB costs, improve product reliability.
The technical solution of the utility model is as follows：
A kind of charging head wiring board, including carrier wiring board, the carrier wiring board are PCB printing plates, and double-sided multi-layer, is in
Rectangle, the tail end of the carrier wiring board extend downwardly out multiple wiring pins, interval, institute are equipped between the wiring pin
State and solder pad is provided with the middle part of wiring pin, multiple apertures, the multiple keyhole welding are offered in the solder pad
After hide.
Further, in the above-mentioned technical solutions, the multiple wiring pin is equipped with four, the first wiring pin and the 4th
The width of wiring pin is more than the width of the second wiring pin and the 3rd wiring pin.
Further, in the above-mentioned technical solutions, in the solder pad of first wiring pin and the 4th wiring pin
Multiple apertures are offered, at least one aperture is offered in the solder pad of second wiring pin.
Relative to the prior art, the beneficial effects of the utility model are：A kind of charging head provided by the utility model
Wiring board quality is applicable in any types USB charging heads and sets beyond quality standard requirement of the USB charging head apparatus to wiring board
It is standby, to be hidden design after punching welding on pad, and the function of welding is not influenced, improve the appearance of PCB, reduce
PCB costs, improve product reliability.
Brief description of the drawings
Fig. 1 is the structure diagram before the utility model consent；
Fig. 2 is the structure diagram after the utility model consent.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Refering to Figure 1, a kind of charging head wiring board provided by the utility model, including carrier wiring board 1, the carrier
Wiring board 1 is PCB printing plates, and double-sided multi-layer, is rectangle, and the tail end of carrier wiring board 1 extends downwardly out multiple wiring pins,
Interval is equipped between wiring pin, solder pad 3 is provided with the middle part of wiring pin, multiple apertures is offered in solder pad 3
4, the multiple aperture 4 is hidden design after welding.
In the present embodiment, the multiple wiring pin is equipped with four, the first wiring pin 21 and the 4th wiring pin 24
Width is more than the width of the second wiring pin 22 and the 3rd wiring pin 23.First wiring pin 21 and the 4th wiring pin 24
Multiple apertures 4 are offered in solder pad 3, such as：Four, two are offered in the solder pad 3 of second wiring pin 22
Aperture 4.
After the charging head wiring board of the present embodiment in solder pad by spiling, while ensureing pad solderability,
It also ensure that impermeable tin to other one side.It specifically has the characteristics that following two：1st, punched on pad, aperture can be complete after being soldered tin
It is complete to hide；2nd, do after ink fills in technique entirely, as shown in Fig. 2, both sides via is filled in extremely, ensure impermeable tin, do not interfere with other one
The function in face.
In conclusion the utility model is suitable for all mobile communication equipments charging class of electronic devices, lifting PCB can be brought
Appearance, the beneficial effect that reduces PCB costs, improve product reliability.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the present invention, all in this practicality
All any modification, equivalent and improvement made within new spirit and principle etc., should be included in the guarantor of the utility model
Within the scope of shield.
