Embodiment
It is below in conjunction with accompanying drawing and specifically real for the purpose of this utility model, technical scheme and advantage is more clearly understood
Mode is applied, the utility model is described in further detail.It should be appreciated that embodiment described herein
Only to explain the utility model, the scope of protection of the utility model is not limited.
The rigid-flexible harden structure of a kind of ladder as shown in Figure 1, including:First rigid region 10, the second rigid region 20, connection
The flexure region 30 of first rigid region 10 and the second rigid region 20, the thickness of first rigid region 10 are firm more than second
Property region 20 thickness, and first rigid region 10 and second rigid region 20 are set in stepped;Described second
The cascaded surface of rigid region 20 is provided with solder mask 40, and one layer of strippable protection materials 50 are covered on the solder mask 40.
Present embodiment is after the rigid-flex board of above-mentioned hierarchic structure is pressed, by coated in the protection on solder mask 40
Impression on material 50 and protection materials 50 is together taken off, exposes the ladder welding resistance interface i.e. solder mask 40 without any impression, side
Just the solder mask 40 for, reliably solving the problems, such as this region is weighed wounded.
Further, since it is covered with the protected material on the solder mask 40 of thin rigid region in second rigid region 20
Material 50, the solder mask 40 on thin rigid region are also resolved the problem of excessive glue, need to only be taken the protection materials 50 off, i.e.,
Excessive glue on solder mask 40 can together be removed, improve the yield of hierarchic structure rigid-flex board.
Further, the protection materials 50 are high temperature resistant peelable glue.Because strippable protection materials 50 are high temperature resistant
The problem of peelable glue, it has the characteristic being easily peeled off, will not be not easily stripped, and degumming enters hole or viscose glue, after ensureing degumming
The surface treatment of solder mask 40 it is smooth, and its resistant to elevated temperatures characteristic meet rigid-flex board make process requirements.
Further, in order to ensure that whole solder masks is not weighed wounded, the resistance need to be completely covered in the protection materials
Layer.Preferably, projected area of the protection materials 50 on solder mask 40 is more than the area of the solder mask 40.It is i.e. described
The profile that the solder mask 40 and protection materials are completely covered in protection materials 50 exceeds the profile of solder mask 40;And the protection
Interval between projected outline and the profile of solder mask 40 of the material 50 on solder mask 40 is at least 0.2mm.Preferably, the guarantor
The scope of spacing distance is 0.2mm- between the projected outline on solder mask 40 of protective material 50 and the profile of solder mask 40
1.0mm, it both ensure that solder mask was not weighed wounded, the waste of protection materials will not be caused again.
In addition, the thickness range of the protection materials 50 is 0.03mm-0.5mm.Protection materials 50 within this range are easy
In stripping, and its thickness ensure that the solder mask 40 positioned at lower floor is not weighed wounded.Preferably, the thickness of the protection materials 50 is
0.05mm.At the position easily weighed wounded or pressing dynamics are larger, it can also suitably increase the thickness of the protection materials 50, avoid
Solder mask 40 below is weighed wounded.
Further, pad 60 or hole, the pad 60 or hole are additionally provided with the cascaded surface of second rigid region 20
One layer of strippable protection materials 50 of upper covering.It ensure that the pad 60 on the cascaded surface of the second rigid region 20 or hole are not wiped
Flower weighs wounded, ensures welding quality.And present embodiment uses high temperature resistant peelable glue rather than PI glue (polyimides glue), PI glue
Although high temperature resistant, its peelable performance is bad;And peelable glue and the associativity of solder mask 40 are good, and when throwing off protection materials 50 again not
Degumming be present and enter hole and the problem of welding resistance is stained with degumming, strippable property is preferable, ensure that whole solder mask 40, pad 60 or the product in hole
Matter and outward appearance, avoid solder mask 40 of the welding resistance of thin ladder slot area i.e. on the second rigid region 20 from being weighed wounded by trough rim, also keep away
The glue stain for having exempted to be laminated, which is sticked on solder mask 40 or pad 60, causes open defect.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
