Abstract
The utility model relates to gauging equipment for adhesive force of interlayer, comprising a gauge board, two sliding rails, and a retaining bracket of laminated boards, a wedge-shaped push-rod and a drawing mechanism for drawing the wedge-shaped push-rod, wherein the gauge board is actively fixed with the sliding rails. A gauge board arranged between the two gauge boards is actively fixed with the retaining bracket of laminated boards. The wedge-shaped push-rod is defined between the two sliding rails. The upfront end of a wedge-shaped surface of the wedge-shaped push-rod is equipped with a filleted corner. The upper end of the two sliding rails is fixed by front and rear beams. The front beam is engaged with an upper movable board which is connected to a bolt via screwed joint. The retaining bracket of laminated boards is also is engaged with a lower movable board which is connected to a bolt via screwed joint. The utility model has the advantages that interlamination adhesive force of complete board difficult to quantify can be transformed to measurable standardized unit number by employing a manner of preset imprint of protective layer on laminated boards to form a protective layer, and breakage of in process of protective lay detaching can be avoided due to usage of employing a wedge-shaped push-rod to detach the protective layer, thereby gagging efficiency can be greatly increased.
Description
Technical field:
The utility model relates to bounding force testing making apparatus technical field, particularly a kind of interlayer adhesion testing making apparatus.
Background technology:
Along with the continuous development of electronics technology, the associated electrical product is also constantly weeded out the old and bring forth the new, but, existing electronic product, it all needs to use the copper-clad plate P.e.c. and pastes electronic component, and therefore, the quality of copper-clad plate is bigger to the quality influence of electronic product.General copper-clad plate is all formed and is had certain thickness laminate by the sticking surface coverage Copper Foil that is incorporated in of a plurality of bonding sheets, process printed wiring board by laminate again, be called for short PCB, if the bounding force of each bonding sheet is less, be that interlayer adhesion is less, then pcb board is behind electronics paster or plug-in unit, phenomenons such as layering plate bursting, boring be bad easily take place in process, thereby cause product rejection, so the test of the bounding force between the bonding sheet then becomes an important step of laminate quality testing.Because the processing technology unanimity of each bonding sheet, the bounding force basically identical between each layer is so only need the bounding force of test top layer bonding sheet and second layer bonding sheet to get final product.The at present normal method of testing of using is the pendulum shock-testing, sees whether section is neat, the size of impact strength, if neat, impact strength greatly then represent that cohesive force is higher, this method of testing need be destroyed the monoblock laminate, therefore causes the large-tonnage product waste; And be subjected to factor affecting such as laminate integral thickness size and thickness evenness, data fluctuations is bigger, and can not directly reflect the adhesion size of laminate interlayer.There is not at present relevant testing making apparatus to address this problem.
The utility model content:
The purpose of this utility model is to provide a kind of interlayer adhesion testing making apparatus at the deficiencies in the prior art.
For achieving the above object, the utility model adopts following technical scheme:
It includes test board, and activity is fixed with two slide rails on the test board, and activity is fixed with the laminate holder on the test board between two slide rails, is limited with wedge shaped ejector pin between two slide rails.
This testing making apparatus also includes the haulage gear of traction wedge shaped ejector pin.
The lozenges of described wedge shaped ejector pin has fillet foremost, to reduce the friction force of wedge shaped ejector pin and the bonding sheet below it.
The upper end of described two slide rails is fixed with the front and back crossbeam, and front beam is combined with upper mobile board, and bolt has been threaded on the upper mobile board; The laminate holder also is combined with down portable plate, and bolt has been threaded on the following portable plate.
The beneficial effects of the utility model are: adopt in advance on laminate stamp to peel off band and form the mode of peeling off band, make that cohesive force changes into the standard unit's numerical value that can test between the whole flaggy that is difficult to quantize; Owing to adopt wedge shaped ejector pin to peel off band, can avoid peeling off band and in the process of peeling off, rupture, can improve the efficient of test greatly.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a test philosophy synoptic diagram of the present utility model;
Fig. 2 is a side view of the present utility model;
Fig. 3 is the schematic cross-section of wedge shaped ejector pin of the present utility model.
Embodiment:
See that Fig. 1-3 laminate interlayer adhesion of the present utility model testing making apparatus includes test board 10, test board 10 is fixed on the test board, activity is fixed with two slide rails 12,14 on the test board 10, activity is fixed with between laminate holder 16, two slide rails 12,14 and is limited with wedge shaped ejector pin 18 on the test board 10 between two slide rails 12,14.
The upper end of two slide rails 12,14 is fixing with front and back crossbeam 22, and front beam 22 is combined with upper mobile board 28, and bolt 30 has been threaded on the upper mobile board 28; Laminate holder 16 also is combined with down portable plate 32, and the bolt 30 that has been threaded on the following portable plate 32 by regulating bolt 30 positions, can be fixed laminate 26 to be measured.
The utility model also includes the haulage gear 20 of traction wedge shaped ejector pin 18, and haulage gear 20 will be avoided contacting with laminate 26 to be measured, reduces mutual friction force.
The lozenges of described wedge shaped ejector pin 18 has fillet 182 foremost, produces cutting force to reduce wedge shaped ejector pin 18 with the friction force of the bonding sheet of its below and to interlayer, as shown in Figure 3.
Described slide rail 12,14 and laminate 26 all vertically are fixed on the test board 10, and haulage gear 20 pulling wedge shaped ejector pins 18 vertically move, as shown in Figure 1.
Described slide rail 12,14 and laminate 26 also can be horizontally fixed on the test board 10, and haulage gear 20 pulling wedge shaped ejector pins 18 move horizontally.
The using method of the utility model testing making apparatus is as follows:
(1), in advance on laminate 26 to be measured stamp peel off and be with 24, certainly, also can directly make the normal width sample by modes such as milling machine, shearing polishings, and will peel off with 24 or an end peel ply pressing plate 26 of normal width sample, described peel off be with 24 or the normal width sample be rectangle, be convenient to the test, the width that this rectangle is peeled off with 24 can adopt 3-5mm, with the parameter demand of adaptive testing instrument, also can select different bandwidth according to different laminates to be measured;
(2), with stamp have peel off with 24 or the laminate 26 of normal width sample be placed on the test board 10, adjust position and fixing;
