Description

Beneficial to the inspection structure of inspection PCB plate through hole conduction
Technical field
This utility model is related to PCB technical field, specifically provides a kind of beneficial to inspection PCB plate through hole conduction Inspection structure.
Background technology
PCB is after anti-welding printing is carried out, developed to carry out 100% inspection out and by development QC (development QC) Test, after the QC inspection OK that develop, carried out 20% sampling observation, PCB after IPQC inspection OK again by quality control in processing procedure (IPQC) Next processing procedure being carried out again, after PCB drags for into lattice row (ARRAY), 100% being carried out by checking machine and is verified, bad plate does sharp Light heavy industry.
Under normal circumstances, every pcb board has 108 PCS, and every batch of pcb board has 200, then carrying out above-mentioned development QC During operation, it is necessary to expend more manpower and time to complete all to check every PCS, be unfavorable for Production requirement.
In view of this, it is special to propose the present invention.
The content of the invention
In order to overcome drawbacks described above, this utility model to provide a kind of inspection knot beneficial to inspection PCB plate through hole conduction Structure, had both greatlyd save Check-Out Time, improve checkability, reduced labor intensity and human cost again.
This utility model in order to solve the technical scheme adopted by its technical problem is:It is a kind of to be beneficial to inspection PCB plate through hole The inspection structure of conduction, sheet frame enclose the periphery located at pcb board, at the corner location of the sheet frame are respectively respectively arranged with one BGA checks pad, each BGA inspections pad respectively to have the spacing between multiple round PAD, and the two neighboring round PAD For 2.95mil;In addition, the aperture of through hole is 0.25mil in each BGA inspections pad.
Used as further improvement of the utility model, the pcb board is to unify the connection piece that typesetting is constituted by multiple PCS plates Plate, the sheet frame are the peripheral sheet frames for entirely joining sheet.
As further improvement of the utility model, in each BGA inspections pad, circuit, and the circle are also formed with The distance between PAD circuits corresponding thereto are 2.5mil.
The beneficial effects of the utility model are:It is compared to needing to test each PCS in prior art, time-consuming to take Power;The present invention only needs to BGA inspections pad described to four and tests, and has both greatlyd save Check-Out Time, has improve Checkability, reduces labor intensity and human cost again, meets Production requirement well.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
With reference to accompanying drawing, make the following instructions:
1 --- sheet frame 2 --- pcb board
3 --- BGA checks pad
Specific embodiment
Embodiment of the present utility model is illustrated by particular specific embodiment below, people skilled in the art can be by Content disclosed in the present specification understands other advantages of the present utility model and effect easily.It should be clear that this specification institute accompanying drawing Structure, ratio, size depicted in formula etc., only to coordinate the content disclosed in description, for being familiar with the people of this skill Scholar understands and reads, and is not limited to the enforceable qualificationss of this utility model, therefore does not have technical essential meaning, appoints What modification of structure, the change of proportionate relationship or adjustment of size, in effect and institute for not affecting this utility model can be generated Under the purpose that can be reached, still all should fall in the range of the technology contents disclosed in this utility model can be covered.
Embodiment 1:
Refer to shown in Figure of description 1, which is the inspection beneficial to inspection PCB plate through hole conduction described in the utility model The structural representation of structure.Sheet frame 1 encloses the periphery located at pcb board 2, is respectively respectively arranged with the corner location of the sheet frame 1 One BGA checks pad 3, each BGA inspections pad 3 respectively to have between multiple round PAD, and the two neighboring round PAD Spacing is 2.95mil (according to the minimum spacing in pcb board);In addition, the aperture of through hole is in each BGA inspections pad 3 0.25mil (according to the minimum-value aperture in pcb board).
In the present embodiment, the pcb board 2 is to unify the connection sheet that typesetting is constituted by multiple PCS plates, and the sheet frame 1 is The peripheral sheet frame of whole connection sheet.
It is also formed between circuit, and round PAD circuits corresponding thereto in each BGA inspections pad 3 Distance is 2.5mil.
Using the operational approach for checking structure to carry out PCB plate through hole conduction inspection of the present invention it is:By four institutes Stating BGA checks the part that pad 3 regards pcb board 2 as to carry out normal operation, and the QC that develops checks four BGA inspections pads Through hole conduction, if having any one BGA inspection pad ink occur enters hole phenomenon, directly chooses and indicates, wait pcb board into After type, directly the abnormal plate for doing sign is sent to verify, and laser heavy industry.Explanation in addition:In PCB finished products do not contain sheet frame and BGA checks pad.
Compared to needing to test each PCS in prior art, waste time and energy;The present invention is only needed to four The BGA inspections pad is tested, and has both greatlyd save Check-Out Time, has improve checkability, has reduced work again Intensity and human cost, meet Production requirement well.
Above-mentioned embodiment only illustrative effect of the present utility model, not for this utility model is limited, should Point out, for those skilled in the art, on the premise of without departing from this utility model know-why, may be used also To make some improvement and modification, these improve and modification is also should be regarded as in protection domain of the present utility model.Additionally, upper The quantity for stating each component in embodiment is only illustrative, also non-for limiting this utility model.
