Abstract
The utility model provides a pressfitting structure is glued to ladder form drag, include: the first bonding sheet that has first mobile critical temperature, leave the type membrane, be located the below of first bonding sheet, first core is formed with first fluting, and first core is located the below from the type membrane, have flow critical temperature's second bonding sheet of the second that is higher than first mobile critical temperature, be formed with and correspond the second that sets up with first fluting and slot, and the second bonding sheet lies in the below from the type membrane, the second core is located the below of second bonding sheet. The utility model discloses can prevent the solation of second bonding sheet regional to the ladder groove of first fluting and the formation of second fluting to play the gluey effect that hinders, it does not have the purpose of gluing the mark and spilling over finally to reach the regional edge in ladder groove, and has reduced manufacturing cost, has improved production efficiency.
Description
Technical field
The utility model relates to circuit board manufacturing area, and particularly a kind of ladder form drag glue laminated closes structure.
Background technology
Along with the small-sized diversified development of electronic product, the restriction of space and fail safe, the PCB of hierarchic structure will dominate the market gradually, and it is mainly used in when client's welding component, need during some to carry out superposing or avoid other components and parts, to ensure the fail safe space of electric elements.
But stepped plate in process of production, just need to use adhesive board pressing of not flowing, or the method using resistance blob of viscose to fill makes, so production cost just improves virtually, efficiency also reduces, and along with the prolongation of production cycle, is just in a disadvantageous position in keen competition.
Further, use above-mentioned two kinds of modes to make stepped plate, not only have strict requirement to technology ability, also there is harsh requirement to production equipment, most importantly, use adhesive board pressing of not flowing, step edges is overflow glue problem, thoroughly cannot improve, annoying industry peer.
Utility model content
The utility model provides a kind of ladder form drag glue laminated and closes structure, with the problem solving that production cost in prior art is high, step edges overflows glue, production efficiency is low etc.
For solving the problem, as an aspect of the present utility model, providing a kind of ladder form drag glue laminated and closing structure, comprising: first bonding sheet with the first flowing critical temperature; Release film, is positioned at the below of the first bonding sheet; First central layer, is formed with the first fluting, and the first central layer is positioned at the below of release film; There is the second bonding sheet of the second flowing critical temperature higher than the first flowing critical temperature, be formed to slot with first corresponding arrange second to slot, and the second bonding sheet is positioned at the below of release film; Second central layer, is positioned at the below of the second bonding sheet.
Preferably, the first bonding sheet and the second bonding sheet are that PP material is made.
In the process that the utility model heats up in pressing, the first bonding sheet can shift to an earlier date gummosis in the first fluting and the second fluting, and has started when the second bonding sheet starts to flow to solidify.Therefore, the step trough region that the solation of the second bonding sheet is formed to the first fluting and the second fluting can be stoped, thus play the effect of resistance glue, finally reach the object of step trough edges of regions glue-free mark spilling, and reduce production cost, improve production efficiency.
Accompanying drawing explanation
Fig. 1 schematically shows the structural representation of the fluting in the utility model on the first central layer;
Fig. 2 schematically shows the layer structure schematic diagram in the utility model before pressing;
Fig. 3 schematically shows the structural representation in the utility model after pressing.
Reference numeral in figure: 1, the first bonding sheet; 2, release film; 3, the first central layer; 4, the second bonding sheet; 5, the second central layer; 6, slot.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Please refer to Fig. 1 to Fig. 3, the utility model provides a kind of ladder form drag glue laminated and closes structure, comprising: first bonding sheet 1 with the first flowing critical temperature; Release film 2, is positioned at the below of the first bonding sheet 1; First central layer 3, is formed with the first fluting, and the first central layer 3 is positioned at the below of release film 2; There is the second bonding sheet 4 of the second flowing critical temperature higher than the first flowing critical temperature, be formed to slot with first corresponding arrange second to slot, and the second bonding sheet 4 is positioned at the below of release film 2; Second central layer 5, is positioned at the below of the second bonding sheet 4.Preferably, the first bonding sheet 1 and the second bonding sheet 4 are made for PP material.As shown in Figure 2, the first fluting and the second fluting superpose the complete fluting 6 of formation one up and down.
In technique scheme, the flowing critical temperature lower than the second bonding sheet 4 of the flowing critical temperature of the first bonding sheet 1, therefore, the two is in the process of pressing intensification, produces the phenomenon of successively flowing.Such as, the flowing critical temperature of the first bonding sheet 1 is 130 DEG C, then it is start flowing at 130 DEG C; The flowing critical temperature of the second bonding sheet 4 is 180 DEG C, then it just starts flowing at 180 DEG C.
Therefore, in the process that pressing heats up, the first bonding sheet 1 can shift to an earlier date gummosis in the first fluting and the second fluting, and has started solidification when the second bonding sheet 4 starts to flow.Therefore, the step trough region that the solation of the second bonding sheet 4 is formed to the first fluting and the second fluting can be stoped, thus play the effect of resistance glue, finally reach the object of step trough edges of regions glue-free mark spilling, and reduce production cost, improve production efficiency.
Owing to have employed technique scheme, the bonding sheet that do not flow that the utility model can use the first cheap bonding sheet fictitious hosts high, thus reduces cost, also improves production efficiency simultaneously, be particularly suitable for bulk production.Finally, low to equipment requirement ability, conventional equipment just can meet making requirement.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
