In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " is connected ", " connection " should be interpreted broadly, such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary.For the ordinary skill in the art, particular case the concrete meaning of above-mentioned term in the utility model can be understood.
Embodiment one
As in Figure 3-5, the pad described in the present embodiment, between two-layer substrate 2, the substrate 2 of every layer is all connected with printed circuit board (PCB) 5, and printed circuit board (PCB) 5 is connected with substrate 2 by COF unit 6; Pad 1 is provided with protrusion element 3, and protrusion element 3 is arranged between printed circuit board (PCB) 5, for filling the space between printed circuit board (PCB) 5.And, be provided with interface unit 4 at the edge of printed circuit board (PCB) 5; Protrusion element 3 is positioned at the both sides of interface unit 4, and that is, protrusion element 3 is disposed on the edge of pad 1, and interface unit 4 is between protrusion element 3.
This pad is filled in the space at interface unit 4 two ends by protrusion element 3, it is not when changing spacer thickness, make a protrusion element 3 in the pad local of printed circuit board (PCB) 5 correspondence, this protrusion element 3 can just fill up the gap between upper and lower two printed circuit board (PCB)s 5.In transportation, this pad plays the effect of fixed printed circuit board 5, makes it can not pull COF unit 6 because there being larger amplitude, thus avoids the COF unit 6 at interface unit 4 two ends to cause injured bad because Oscillation Amplitude is large.
Preferably, the height of protrusion element 3 is 2-3mm, makes it can just fill gap between completely upper and lower two printed circuit board (PCB)s 5.Certainly, also can arrange flexibly according to actual needs.
And this pad 1 can keep original structure, cost-saving.Pad 1 is EPE (Pearl wool material) with the material of protrusion element 3.Certainly, also other elastic materials can be adopted according to actual needs.
In the present embodiment, protrusion element 3 is wave structure; As shown in Figure 6, wave structure comprises multiple flat segments 31 and raised section 32, and multiple flat segments 31 and raised section 32 in being alternately distributed, thus form wave-like on pad 1.
Further, dashpot 33 is provided with in the below of raised section 32.Dashpot 33 can be the groove of semicircle shape, thus plays damping, buffering effect, can also reduce materials when producing simultaneously.
Corresponding, from shape, this pad 1 comprises base material 11 and the first connecting portion 12; The shape of base material 11 is rectangle, and the first connecting portion 12 is positioned at the side on the long limit of base material 11, and the shape of the first connecting portion 12 is similar rectangle too; This protrusion element 3 is positioned on the first connecting portion 12.Certainly, base material 11 and the first connecting portion 12, protrusion element 3 are all formed in one, and just just carry out modularization fractionation for convenience of describing.
In addition, this pad 1 also comprises the second connecting portion 13; The shape of the second connecting portion 13 is rectangle, is positioned at the side of base material 11 minor face at the second connecting portion 13, and for padding the side being located at substrate 2, it is corresponding with the COF of substrate 2 side is arranged.
Embodiment two
As Figure 7-8, the technology contents not repeated description that the present embodiment two is identical with embodiment one, disclosed in embodiment one, content also belongs to content disclosed in the present embodiment two, and the present embodiment two and embodiment one are distinguished and be: this protrusion element 3 is convex cylinder; And the quantity of convex cylinder is multiple, and multiple convex cylinder is spaced apart on pad 1, and the height of each convex cylinder is identical.This convex cylinder also can fill up the gap between upper and lower two printed circuit board (PCB)s 5.In transportation, playing the effect of fixed printed circuit board 5, COF unit 6 can not be pullled because there being larger amplitude, thus avoid the COF unit 6 at interface unit 4 two ends due to Oscillation Amplitude injured greatly.
Preferably, the cross-sectional plane of convex cylinder is circular or square or triangle.The cross-sectional plane of convex cylinder also and limit to, can be arranged flexibly.
During transport, at each box house, multilager base plate 2 can be housed, the pad according to any one of an above-described embodiment be all set between substrate 2 and substrate 2, thus play the effect of fixed printed circuit board 5.
In sum, the utility model provides a kind of pad, and when not changing original spacer thickness, a protrusion element is made in the pad local corresponding at printed circuit board (PCB), and this protrusion element can just fill up the gap between upper and lower two printed circuit board (PCB)s.In transportation, this protrusion element plays the effect of fixed printed circuit board, and it can not be made to pull COF because of larger amplitude, thus injured etc. is bad to avoid COF to occur.
Embodiment of the present utility model provides for the purpose of example and description, and is not exhaustively or by the utility model be limited to disclosed form.Many modifications and variations are apparent for the ordinary skill in the art.Selecting and describing embodiment is in order to principle of the present utility model and practical application are better described, and enables those of ordinary skill in the art understand the utility model thus design the various embodiments with various amendment being suitable for special-purpose.
