Description
Technical field
The utility model relates to pcb board field, and specifically a kind of pcb board tensile test assists apparatus for leveling.
Background technology
Printed circuit board (pcb) needs to carry out a series of reliability testing, comprising circuit peel strength test, circuit peel strength test is the test event of the adhesion on test PCB between copper wire and base material, and peel strength test must ensure that peel off circuit keeps vertical with substrate always.
The equipment for testing PCB circuit peel strength sold in the market, its chuck does not all consider the situation that can bend when PCB is very thin.
Along with modern electronic product is to frivolous development need, PCB will do thinner and thinner, and the relatively thick pcb board of thin pcb board hardness is poor.
Except circuit peel strength, also have the test of pad pull-off strength, the test of pad pull-off strength is the unit clamp of the maximum pull that testing weld pad departs from needed for base material, not this test on the market at present.The test of pad pull-off strength completes often and gong has become the test that shipment unit pcb board carries out again, all less being not enough to of most of shipment unit is fixed by the peel strength test fixture of puller system on the one hand, even if plate is enough large on the other hand, affect test result because adhesion often causes plate member bent too greatly.
Summary of the invention
The purpose of this utility model is that providing a kind of can fix PCB and prevent the bending pcb board tensile test of PCB from assisting apparatus for leveling, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of pcb board tensile test assists apparatus for leveling, be one piece for pcb board being pressed abd fixed on the sheet material on scooter, and go out a groove at the middle gong of sheet material.
As further program of the utility model: described sheet material is the rectangular parallelepiped sheet material of high rigidity high rigidity, and its length, width and thickness suitably adjust according to concrete fixture situation.
As further program of the utility model: described sheet material selects sheet metal or thick pcb board material.
As further program of the utility model: described groove is rectangle, its width and length suitably adjust according to concrete fixture situation.
As further program of the utility model: described groove gong becomes to be more suitable for the square of pad pull-off strength test.
Compared with prior art, the beneficial effects of the utility model are: this pcb board tensile test assists apparatus for leveling can effectively prevent from bending during thin PCB conducting transmission line peel strength test, ensure the accuracy of result; Can fritter sample be made to carry out peel strength test by fixing PCB fritter sample; Can sample be made to carry out the test of pad pull-off strength by fixing PCB fritter sample; Result of use is remarkable.This apparatus for leveling can be gone out form by gong machine figure gong, makes simple.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 3, existing a kind of test fixture, comprise upper grip 1, scooter 2 and track 3.
Refer to Fig. 4-10, a kind of pcb board tensile test assists apparatus for leveling, be one piece for pcb board being pressed abd fixed on the sheet material 4 on scooter 2, and go out a groove 41 at the middle gong of sheet material 4.Described sheet material 4 is the rectangular parallelepiped sheet material of high rigidity high rigidity, and its length, width and thickness suitably adjust according to concrete fixture situation; Described sheet material 4 selects sheet metal or thick pcb board material; Described groove 41 is rectangle, and its width and length suitably adjust according to concrete fixture situation; Described groove 41 even can gong become be more suitable for pad pull-off strength test square.
Refer to Fig. 6, when normal slab carries out peel strength test, can not bending phenomenon occurs; And thin plate is when carrying out peel strength test, easily bending phenomenon occurs (referring to Fig. 7).
Refer to Fig. 8, when increasing the utility model and carry out peel strength test on thin plate, effectively avoid bending now; Refer to Fig. 9, the pcb board that element length is inadequate increases the utility model and not only can carry out peel strength test, and effectively avoid that bending phenomenon occurs; Refer to Figure 10, pcb board increases the utility model and can carry out the test of pad pull-off strength.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
