Abstract
This utility model provides a kind of mobile phone camera rigid-flex combined board pressing structure, including FPC plate be covered in the pure glue on FPC plate two sides, central layer, cushion pad successively.Owing to using the mode of central layer+pure glue, it is possible to resolve the problem of the plate surface uniformity difference caused by wiring board inner figure difference of height in bonding processes, additionally, pure glue gummosis amount only has 0.1mm, the unmanageable problem of gummosis will not be produced, and pure glue has bending resistance folding endurance, has no adverse effect FPC plate.
Description
Technical field
This utility model relates to wiring board and manufactures field, is specifically related to a kind of rigid-flex combined board for mobile phone camera
Pressing structure.
Background technology
The feature of mobile phone camera rigid-flex combined board is that the thickness of plate is little, and usual thickness is between 0.3mm ~ 0.45mm, and
Hardboard part uniformity requirement is high, it is desirable to thickness extreme difference≤8 μm.Traditional iterative structure of this kind of rigid-flex combined board employing is 3
Close 1 cushion pad+copper+PP+FPC+PP+ copper+3 and close 1 cushion pad, owing to PP material and cushion pad material are all by solid at bonding processes
State arrives the process of solid-state again to liquid, is affected by FPC and inner figure difference of height and can cause asking of force fit plate surface uniformity difference
Topic, flatness extreme difference is above standard requirement, it is also possible to there will be PP pressing gummosis and is difficult to control to problem etc., affects crudy.
Utility model content
For solving the problems referred to above, this utility model provides a kind of mobile phone camera rigid-flex combined board pressing structure, including FPC
Plate and be covered in the pure glue on FPC plate two sides, central layer, cushion pad successively；Pure glue is covered in the two sides of FPC plate, and central layer is covered in pure
On glue, cushion pad is covered on central layer.
Preferably, described pure glue thickness is 23 ~ 27 μm.
Preferably, described central layer is single-side coated copper plate, and the copper face on described central layer is towards cushion pad.
Further, described core thickness is 0.09 ~ 0.12mm.
Further, described central layer is FR4 copper-clad plate.
Preferably, described cushion pad includes buffering plastic foil and being covered in the mould release membrance on buffering plastic foil two sides.
Further, described buffering plastic foil thickness is 0.18 ~ 0.22mm, and mould release membrance thickness is 0.09 ~ 0.12 mm.
Owing to using the mode of central layer+pure glue, it is possible to resolve bonding processes is caused by wiring board inner figure difference of height
The problem of plate surface uniformity difference, it addition, pure glue gummosis amount only has 0.1mm, the unmanageable problem of gummosis will not be produced, and pure
Glue has bending resistance folding endurance, has no adverse effect FPC plate.
Accompanying drawing explanation
Fig. 1 is the mobile phone camera rigid-flex combined board pressing structure embodiment schematic diagram that this utility model provides.
Fig. 2 is the mobile phone camera rigid-flex combined board cushion pad embodiment schematic diagram that this utility model provides.
Detailed description of the invention
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing and embodiment, this utility model to be entered
One step describes in detail.
Mobile phone camera rigid-flex combined board pressing structure as shown in Figure 1, including FPC plate 1 be covered in FPC plate 1 liang successively
The pure glue 2 in face, central layer 3, cushion pad 4；Pure glue 2 thickness is 25 μm, and central layer 3 is the FR4 single-side coated copper plate that thickness is 0.1 mm, core
The copper face 31 of plate 3 is towards cushion pad 4.As in figure 2 it is shown, cushion pad 4 includes buffering plastic foil 41 and the covering that thickness is 0.2mm
In the mould release membrance 42 on buffering plastic foil 41 two sides, mould release membrance 42 thickness is 0.1mm.
Being more than specific implementation of the present utility model, it describes more concrete and detailed, but can not therefore manage
Solve as the restriction to this utility model the scope of the claims.It should be pointed out that, for the person of ordinary skill of the art, not
On the premise of departing from this utility model design, it is also possible to making some deformation and improvement, these obvious alternative forms are equal
Belong to protection domain of the present utility model.
