- the circuit board assembly provided in the first aspect of the present application comprises a structural member disposed on a second region of the first surface of the circuit board, wherein the inner core of the structural member is electrically connected to the circuit board.
- the inner core of the structural member can be electrically connected to any metal functional layer (e.g., a power layer, a conductor layer, etc.) on the circuit board, which is equivalent to making the inner core of the structural member a part of the metal functional layer to which it is connected.
- the inner core of the structural member increases the area and thickness of the corresponding metal functional layer, thereby reducing the impedance of the metal functional layer in the circuit board to a certain extent while maintaining the volume of the circuit board, thereby improving the electrical performance of the metal functional layer.
- the insulating layer wrapped around the outer surface of the inner core can prevent the inner core from directly contacting surrounding components and causing a short circuit.

Description
本申请要求于2024年03月28日提交国家知识产权局、申请号为202420657668.2、发明名称为“电路板组件和电子设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请实施例涉及电子设备技术领域,尤其涉及一种电路板组件和电子设备。
随着电子设备的发展,电子设备越来越追求轻薄化和小型化,而轻薄化和小型化的实现主要依赖于电子设备内部各部件体积的减小。例如,电子设备中的电路板,其面积和厚度均在减小,这就造成电路板中的各金属功能层(例如电源层、导线层等)的面积和厚度也随之减小,进而导致电路板的阻抗增大。
本申请实施例提供一种电路板组件和电子设备,用于解决现有的电路板在小型化时造成其内部金属功能层阻抗增大的问题。
为达到上述目的,本申请实施例采用如下技术方案:
第一方面,本申请实施例提供了一种电路板组件,包括电路板、元器件和结构件。
其中,电路板具有第一表面,第一表面包括第一区域和第二区域。元器件位于第一区域,且元器件与电路板电连接。结构件位于第二区域,结构件包括内芯和绝缘层,内芯与电路板电连接,且绝缘层包裹内芯。
本申请第一方面提供的电路板组件,通过在电路板的第一表面的第二区域上设置结构件,且结构件的内芯与电路板电连接,其中,结构件的内芯可以与电路板上任一金属功能层(例如电源层、导线层等)相电连接,相当于使结构件的内芯成为了与其相连接的金属功能层的一部分,利用结构件的内芯增大了相对应的金属功能层的面积和厚度,从而在电路板的体积不变的前提下,在一定程度上能够减小电路板中金属功能层的阻抗,进而能够改善金属功能层的电性能指标。并且,包裹在内芯外侧的绝缘层,能够防止内芯直接与周围的元器件接触造成短路。
结合第一方面,在一种可能的实现方式中,第二区域位于相邻的两个元器件之间。其中,上述元器件可以是有源器件(例如CPU、GPU、LPDDR等),也可以是无源器件(例如电阻、电容、电感、滤波器等)。这样一来,相当于将结构件设置于电路板上相邻的元器件之间的空白区域,进而在通过结构件优化金属功能层的阻抗的同时,还能够提高电路板的表面利用率,有利于电路板的小型化。
结合第一方面,在另一种可能的实现方式中,第二区域位于电路板的边缘。这样一来,相当于将结构件设置于电路板边缘未设置元器件的空白区域,进而在利用结构件降低电路板中金属功能层的阻抗的同时,还能够提高电路板的表面利用率,有利于电路板的小型化。
结合第一方面,在另一种可能的实现方式中,电路板上与第二区域对应的部分的结构强度,小于与第一区域对应的部分的结构强度。由此设置,相当于还可以利用结构件对电路板上强度较为薄弱的部分进行加强,即上述结构件对于电路板具有“降低阻抗”和“结构补强”双重作用。
结合第一方面,在另一种可能的实现方式中,元器件包括第一电子器件和第二电子器件,第一电子器件设置于第一表面上,第二电子器件设置于第一电子器件远离第一表面的表面上,第一电子器件与电路板电连接,第二电子器件与第一电子器件电连接。第二电子器件在第一表面上的垂直投影覆盖结构件在第一表面上的垂直投影的至少部分区域。
其中,由于第二电子器件与第一电子器件连接后,在第一电子器件周围具有第二电子器件与电路板之间形成的间隙,该间隙的高度较小,而元器件大多数为标准件,其高度远大于该间隙的高度,无法布置在该间隙中。而上述结构件的高度可根据需求任意设置,故可将结构件设置于第二电子器件与电路板之间的间隙中,这样一来,结构件无需占用电路板上其它可正常设置元器件的区域,从而能够提高电路板的表面利用率,有利于电路板的小型化。
结合第一方面,在另一种可能的实现方式中,第一电子器件为连接器,第二电子器件为柔性电路板,柔性电路板的另一端用于连接电子部件。例如,第一电子器件可以为板对板连接器的母座,柔性电路板的一端设有连接器的公座,通过将公座和母座对接即可实现柔性电路板与电路板之间的电连接。
结合第一方面,在另一种可能的实现方式中,结构件设置有多个,多个结构件绕第一电子器件间隔设置。由此设置,能够充分利用第一电子器件周围在第二电子器件与电路板之间形成的间隙,且多个结构件能够进一步降低电路板中金属功能层的阻抗。其中,多个结构件可以与同一金属功能层电连接,也可以分别与不同金属功能层电连接。
结合第一方面,在另一种可能的实现方式中,电路板上开设有多个开孔,开孔沿电路板的厚度方向贯穿电路板,第二区域位于相邻的两个开孔之间。也就是说,相当于结构件设置在电路板上两个开孔之间的窄条部分上,这样一来,结构件在降低电路板中金属功能层的阻抗的同时,还可以增强该窄条部分的结构强度,从而能够降低电路板在受到冲击或震动时该窄条部分出现断裂的风险,进而能够保证电路板的可靠性和稳定性。
结合第一方面,在另一种可能的实现方式中,电路板组件还包括紧固件,结构件通过紧固件固定在电路板上。由此设置,利用紧固件不仅能够将结构件固定的更加牢固,还能够简化结构件与电路板之间的装配工序(例如紧固件为螺钉,电路板上开设有螺孔,结构件上开设有通孔,螺钉的一端穿过通孔后拧紧在螺孔中即可完成对于结构件的固定)。
结合第一方面,在另一种可能的实现方式中,在电路板的厚度方向上,结构件的高度为H,其中,H≤0.25mm。
结合第一方面,在另一种可能的实现方式中,在电路板的厚度方向上,内芯的高度为h,其中,0.15mm≤h≤0.2mm。由此设置,当结构件位于第一电子器件周围在第二电子器件与电路板之间形成的间隙中时,结构件能够取得较高的内芯厚度收益,内芯厚度越大,越有利于降低与其电连接的金属功能层的阻抗。
结合第一方面,在另一种可能的实现方式中,内芯的材质为铜。
结合第一方面,在另一种可能的实现方式中,绝缘层的材质为EMC绝缘材料。这样一来,绝缘层不仅能够防止内芯与周围的元器件直接接触造成短路,由EMC绝缘材料制成的绝缘层还具有较好的机械强度,能够对整个结构件起到一定的支撑作用,进而提升结构件的抗冲击性能。
第二方面,本申请提供了一种电子设备,该电子设备包括壳体和上述第一方面提供的电路板组件,其中,壳体内部形成有容纳腔,电路板组件设置于容纳腔内。
可以理解地,上述提供的第二方面及其任一种可能的实现方式所述的电子设备所能达到的有益效果,可参考如第一方面及其任一种可能的实现方式中的有益效果,在此不再赘述。

请参见图1和图2所示,图1为本申请实施例提供的电子设备01的整体结构示意图,图2为上述图1中电子设备01的结构爆炸图。由上述可知,在本实施例中,该电子设备01为手机,且电子设备01可以呈近似矩形板状结构。该电子设备01可以包括显示模组10、壳体20、摄像头模组30、摄像头装饰盖50、电池60以及电路板41。
可以理解的是,图1和图2仅示意性的示出了电子设备01包括的一些部件,这些部件的实际形状、实际大小、实际位置和实际构造不受图1和图2的限制。
上述显示模组10用于显示图像、视频等。显示模组10可以包括透光盖板11和显示屏12(英文名称:panel,也成为显示面板),透光盖板11与显示屏12层叠设置。该透光盖板11的材质包括但不限于玻璃。例如,透光盖板11可以采用普通的透光盖板,用于保护显示屏,以避免显示屏因外力导致损坏,并且能够起到防尘作用。或者,透光盖板11也可以采用具有触控功能的透光盖板,以使电子设备01具有触控功能,从而使用户使用更加方便。因此,本申请对于透光盖板11的具体材质不作特殊限定。
此外,上述显示屏12可以采用柔性显示屏,也可以采用刚性显示屏。例如,显示屏12可以为有机发光二极管(organic light-emitting diode,OLED)显示屏,有源矩阵有机发光二极体或主动矩阵有机发光二极体(active-matrix organic light-emitting diode,AMOLED)显示屏,迷你发光二极管(mini organic light-emitting diode)显示屏,微型发光二极管(micro organic light-emitting diode)显示屏,微型有机发光二极管(micro organic light-emitting diode)显示屏,量子点发光二极管(quantum dot light emitting diode,QLED)显示屏,液晶显示屏(liquid crystal display,LCD)。
上述壳体20用于保护电子设备01内部的电子器件。壳体20可以包括电池盖21和边框22,电池盖21位于显示屏12远离透光盖板11的一侧,并与透光盖板11、显示屏12层叠设置,边框22位于透光盖板11与电池盖21之间。电池盖21固定于边框22上,示例性地,电池盖21可以通过粘接、螺纹连接、焊接、卡接等方式固定于边框22上。透光盖板11可以通过胶粘固定于边框22上,以使透光盖板11、电池盖21以及边框22围成电子设备01内部的容纳腔,上述显示屏12、摄像头模组30、电池60以及电路板41均设置于该容纳腔内。
上述摄像头模组30用于实现视频或者图像的拍摄,并可实现自动对焦(AF,Auto Focus),从而能够适用于多种拍摄场景。摄像头模组30可以如图1所示设置于电池盖21靠近一侧边沿的位置处。或者,摄像头模组30可以位于电池盖21的上部的中间位置处(图中未示出)。因此,本申请对于摄像头模组30的具体位置不作特殊限定。
上述摄像头装饰盖50用于避免外界的灰尘等异物进入到电子设备01内部或摄像头模组30内,以及防止摄像头模组30受到外界物体的刮擦或撞击。
上述电路板41用于设置电子设备10的元器件42并实现元器件42之间的电连接,请参见图3所示,图3为图2中的元器件42布置在电路板41上的正视图(沿Z轴负向)。上述元器件42可以为有源器件(例如中央处理器(Central Processing Unit,CPU)、图形控制芯片(graphics processing unit,GPU)、低功耗双倍数据速率内存(Low Power Double Data Rate SDRAM,LPDDR)、通用存储器(universal flash storage,UFS)等),也可以为无源器件(例如电阻、电容、电感、滤波器等)。
为方便下文描述,建立XYZ坐标系,定义电路板41的宽度方向为X轴方向,电路板41的长度方向为Y轴方向,电路板41的厚度方向为Z轴方向。其中,电路板41的厚度方向即为上述电子设备01的厚度方向,电路板41的长度方向可以为电子设备01的长度方向,且电路板41的宽度方向为电子设备01的宽度方向。
请继续参见图3,并结合图4所示,图4为图3中A-A处的截面(平行于XZ平面)示意图。上述电路板41可以包括基板411和多个金属功能层412,多个金属功能层412可以包括导线层4121和电源层4122。其中,基板411具有第一表面401,导线层4121和元器件42均设置于第一表面401,且元器件42和导线层4121电连接,导线层4121用于在各元器件42之间传输电流和信号。电源层4122设置于基板411内,且与上述电池60电连接,元器件42中的有源器件通过基板411上相应的过孔100与电源层4122电连接,电源层4122用于为有源器件提供稳定的电源供应。
可以理解的是,金属功能层412可以覆盖基板411上平行于XY平面的整个截面(例如电源层4122),也可以覆盖基板411上平行于XY平面的截面的一部分,在基板411上平行于XY平面的截面内,金属功能层412还可以是网状结构(例如导线层4121)。
随着电子设备01向小型化、轻薄化的方向发展,电子设备01中电路板41的面积和厚度越来越小,这就造成电路板41上的各种金属功能层412的面积和厚度也越来越小,进而导致各金属功能层412的阻抗增大。
为解决上述技术问题,本申请实施例提供了一种电路板组件40,请参见图5、图6所示,图5为本申请实施例提供的一种电路板组件40的正视图(沿Z轴负向),图6为图5中B-B处的截面(平行于XZ平面)示意图。
该电路板组件40包括结构件43、上述电路板41和上述元器件42。电路板41包括基板411和多个金属功能层412,多个金属功能层412可以包括导线层4121和电源层4122。基板411具有第一表面401,导线层4121和元器件42均设置于第一表面401上,且元器件42和导线层4121电连接。电源层4122设置于基板411内,元器件42中的有源器件通过基板411上相应的过孔100与电源层4122电连接。
其中,第一表面401包括第一区域401a和第二区域401b,上述元器件42位于第一区域401a。结构件43位于第二区域401b(图5中虚线方框区域,且第一表面401上除第二区域401b之外的区域均属于第一区域401a),结构件43包括内芯431和绝缘层432,内芯431与电路板41的其中一个金属功能层412电连接(例如图6中内芯431通过基板411上相应的过孔100与电源层4122电连接),且绝缘层432包裹内芯431。
需要说明的是,上述结构件43可以设置一个,也可以设置多个。当结构件43设置有多个时,多个结构件43可以与同一个金属功能层412电连接,多个结构件43可以分别与不同金属功能层412电连接。
相应的,第二区域401b可以设置一个,也可以设置多个,一个第二区域401b内可以设置一个结构件43,也可以设置多个结构件43,本申请对此不作特殊限定。
请参见图7所示,图7为本申请实施例提供的一种结构件43的剖面图。图7中,上述内芯431的一侧表面可完全露出。安装时,该露出的表面贴合在电路板41上,内芯431通过该露出的表面与相对应的金属功能层412进行电连接,内芯431的其余表面均被绝缘层432覆盖。
或者,请参见图8所示,图8为本申请实施例提供的另一种结构件43的剖面图。图8中,还可以在内芯431朝向基板411的表面设有凸起的焊点4311,绝缘层432将内芯431焊点4311以外的部分完全包裹。安装时,内芯431通过该焊点4311与相对应的金属功能层412进行电连接。当然,内芯431还可以通过其它方式与相应的金属功能层412电连接,在此不再赘述。
内芯431的材质可以为铜、铝、银、石墨等导电性较好的金属或非金属。
上述绝缘层432可以通过在内芯431的外侧一次性注塑成型,也可以是贴覆在内芯431外表面的绝缘膜,本申请对此不作特殊限定。
绝缘层432的材料可以是EMC(Epoxy Molding Compound,环氧树脂模塑料)、PI(Polyimide,聚酰亚胺)、PTFE(Polytetrafluoroethylene,聚四氟乙烯)等有机高分子材料。
这样一来,通过在电路板41的第一表面401的第二区域401b上设置结构件43,且结构件43的内芯431与电路板41电连接,其中,结构件43的内芯431可以与电路板41上任一金属功能层412(例如电源层4122、导线层4121等)相电连接,相当于使结构件43的内芯431成为了与其相连接的金属功能层412的一部分,利用结构件43的内芯431增大了相对应的金属功能层412的面积和厚度,从而在电路板41的体积不变的前提下,在一定程度上能够减小电路板41上金属功能层412的阻抗,进而能够改善金属功能层412的电性能指标。
并且,包裹在内芯431外侧的绝缘层432,能够防止内芯431直接与周围的元器件42接触造成短路。当绝缘层432采用EMC绝缘材料时,由EMC绝缘材料制成的绝缘层432还具有较好的机械强度,能够对整个结构件43起到一定的支撑作用,进而提升结构件43的抗冲击性能。
为便于理解,以下均是以内芯431的一侧表面完全露出并贴合在电路板41上,内芯431的其余表面均被绝缘层432覆盖为例进行的举例说明。
在一些实施例中,请参见图9和图10所示,图9为本申请实施例提供的又一种电路板组件40的正视图(沿Z轴负向),图10为图9中C-C处的截面(平行于XZ平面)示意图。元器件42设置有多个,第二区域401b可以位于相邻的两个元器件42之间。由此设置,相当于将结构件43设置于基板411上相邻的元器件42之间的空白区域,进而在通过结构件43优化金属功能层412的阻抗的同时,还能够提高基板411的表面利用率,有利于电路板41的小型化。
例如,请继续参见图9、图10所示。元器件42设置有三个,分别为第一元器件42a、第二元器件42b和第三元器件42c,其中,第一元器件42a为电容,第二元器件42b为GPU,第三元器件42c为滤波器,在图示方位中,第一元器件42a、第二元器件42b和第三元器件42c沿电路板41的宽度方向从左到右依次间隔分布,且分别与导线层4121电连接。由于CPU为有源器件,故第二元器件42b还通过基板411上相应的过孔100与电源层4122电连接。
电路板41上设置有两个结构件43,分别为第一结构件43a和第二结构件43b。第一元器件42a和第二元器件42b之间的空白区域为左侧第二区域4011,第一结构件43a设置于左侧第二区域4011,第二元器件42b和第三元器件42c之间的空白区域为右侧第二区域4012,第二结构件43b设置于右侧第二区域4012,且第一结构件43a和第二结构件43b分别通过基板411上相应的过孔100与电源层4122连接。由此,利用三个间隔设置的元器件42之间的空白区域设置了两个结构件43,且两个结构件43均与电源层4122电连接,这样不仅能够减小电源层4122的阻抗,且还提高了基板411第一表面401的利用率。
在一些实施例中,请参见图11、图12所示,图11为本申请实施例提供的又一种电路板组件40的正视图(沿Z轴负向),图12为图11中E-E处的截面(平行于XZ平面)示意图。其中,第二区域401b还可以位于电路板41的边缘。这样一来,相当于将结构件43设置于电路板41边缘未设置元器件42的空白区域,进而在利用结构件43降低电路板41中金属功能层412的阻抗的同时,还能够提高电路板41的表面利用率,有利于电路板41的小型化。
例如,请继续参见图11和图12所示。其中,基板411呈矩形,设置元器件42的第一区域401a占据基板411上第一表面401的中间位置,在第一表面401的边缘形成有绕第一区域401a延伸一周的空白区域,该空白区域即可作为第二区域401b,在该矩形环状的第二区域401b上设置一个环状的结构件43,结构件43绕第一区域401a延伸一周,且结构件43通过基板411上相应的过孔100与电源层4122连接,从而在最大限度的利用第一表面401的面积而不挤占布置元器件42的空间的同时,还能够降低电源层4122的阻抗。
再例如,请参见图13所示,图13为本申请实施例提供的又一种电路板组件40的正视图(沿Z轴负向)。其中,基板411呈矩形,设置元器件42的第一区域401a占据基板411上第一表面401的中间位置,在第一表面401的边缘形成有绕第一区域401a延伸一周的空白区域,该空白区域即可作为第二区域401b。第二区域401b包括平行于Y轴方向的左侧第二区域4011和右侧第二区域4012,以及平行于X轴方向的上部第二区域4013和下部第二区域4014。
电路板41上结构件43设置有四个,分别为第一结构件43a、第二结构件43b、第三结构件43c和第四结构件43d。其中,请继续参见图13,并结合图14所示,图14为图13中F-F处的截面(平行于XZ平面)示意图。第一结构件43a和第三结构件43c分别设置于左侧第二区域4011和右侧第二区域4012,且第一结构件43a和第三结构件43c均与导线层4121电连接,从而能够降低导线层4121的阻抗。
请继续参见图13,并结合图15所示,图15为图13中G-G处的截面(平行于YZ平面)示意图。第二结构件43b和第四结构件43d分别设置于上部第二区域4013和下部第二区域4014,且第二结构件43b和第四结构件43d分别通过相应的过孔100与电源层4122电连接,从而能够降低电源层4122的阻抗。
在上述基础上,电路板41上与第二区域401b对应的部分的结构强度,小于与第一区域401a对应的部分的结构强度。由此设置,相当于还可以利用结构件43对电路板41上强度较为薄弱的部分进行加强,即上述结构件43对于电路板41具有“降低阻抗”和“结构补强”双重作用。
例如,请参见图16、图17所示,图16为本申请实施例提供的又一种电路板组件40的正视图(沿Z轴负向),图17为图16中J-J处的截面(平行于XZ平面)示意图。其中,基板411上第一区域401a设置有一个,第二区域401b设置有两个,两个第二区域401b分别为左侧第二区域4011和右侧第二区域4012,在图示方位中,左侧第二区域4011和右侧第二区域4012分别位于第一区域401a的左、右两侧。
基板411上与第一区域401a对应的部分为第一部分411a,第一部分411a的厚度为D1。基板411上与左侧第二区域4011对应的部分为第二部分411b,第二部分411b的厚度为D2。基板411上与右侧第二区域4012对应的部分为第三部分411c,第三部分411c的厚度为D3。
从图17中可看出,D3<D2<D1。而由于基板411各处密度均匀,因此第二部分411b和第三部分411c的强度均小于第一部分411a的强度。此时,通过在基板411上设置两个结构件43,两个结构件43分别为第一结构件43a和第二结构件43b。其中,第一结构件43a设置在左侧第二区域4011,以对基板411的第二部分411b进行结构补强。第二结构件43b设置在右侧第二区域4012,以对基板411的第三部分411c进行结构补强。且第一结构件43a的内芯431和第二结构件43b的内芯431分别通过相应的过孔100与电源层4122电连接,从而还能够降低电源层4122的阻抗。
在一些实施例中,请参见图18和图19所示,图18为本申请实施例提供的又一种电路板组件40的正视图(沿Z轴负向),图19为图18中K-K处的截面(平行于XZ平面)示意图。
其中,电路板41上元器件42设置有三个,分别为第一元器件42a、第二元器件42b和第三元器件42c,第一元器件42a、第二元器件42b和第三元器件42c分别与导线层4121电连接。其中,第一元器件42a可以包括第一电子器件421和第二电子器件422,第一电子器件421设置于第一表面401上,第二电子器件422设置于第一电子器件421远离第一表面401的表面上,第一电子器件421与电路板41电连接,第二电子器件422与第一电子器件421电连接。第二元器件42b为电容,第三元器件42c为通用存储器。
当上述第二电子器件422与第一电子器件421连接后,在第一电子器件421周围会具有第二电子器件422与基板411之间形成的间隙500,该间隙500的高度较小,而由于元器件42一般为标准件,其高度远大于该间隙500的高度,例如,第一电子器件421为板对板连接器(Board-to-Board Connectors,BTB),第二电子器件422为柔性电路板(Flexible Printed Circuit,FPC),元器件为0603贴片电容。柔性电路板的一端也设有板对板连接器,柔性电路板的另一端用于连接其它电子部件(如摄像头模组、麦克风、听筒等),当柔性电路板上的板对板连接器与基板411上的板对板连接器对接后,柔性电路板与基板411之间的间隙500高度一般在0.35mm左右,而0603贴片电容的厚度为一般为0.8mm,远大于0.35mm,这就导致0603贴片电容(元器件42)无法布置在间隙500中,进而造成了第一表面401面积的浪费。
而上述结构件43一般为非标准件,故结构件43在制造时的其高度可根据需求任意设置,因此,可将结构件43设置在上述间隙500中,即第二电子器件422在第一表面401上的垂直投影能够覆盖结构件43在第一表面401上的垂直投影的至少部分区域。这样一来,结构件43不仅不会占用基板411上其它可正常设置元器件42的区域,还能使第一表面401上无法正常布置元器件42的区域得到有效利用,从而能够提高基板411的表面利用率,有利于电路板41的小型化。
示例性的,请继续参见图18、图19所示,第一电子器件421为板对板连接器的母座,第一电子器件421与导线层4121连接,第二电子器件422为柔性电路板。柔性电路板的一端设有板对板连接器的公座,通过将公座和母座对接即可实现柔性电路板与电路板41之间的电连接。公座和母座对接后,在柔性电路板(第二电子器件422)与基板411之间会形成间隙500,图19所示方位中,第二结构件43b和第一结构件43a设置于间隙500中,且分别位于第一电子器件421的左右两侧,第一结构件43a和第二结构件43b在第一表面401上的垂直投影完全被柔性电路板(第二电子器件422)在第一表面401上的垂直投影覆盖,从而能够充分利用基板411的第一表面401,有利于电路板41的小型化。
随着封装技术的发展,连接器的公座和母座对接后,柔性电路板(第二电子器件422)与基板411之间的间隙500的高度d逐渐被控制在小于或等于0.25mm。因此,为保证结构件43能够顺利布置到该间隙500中,请继续参见图19所示,在电路板41的厚度方向上,第一结构件43a的高度H也需小于或等于0.25mm,从而避免第一结构件43a对连接器的对接造成影响。例如,第一结构件43a的高度H可以为0.25mm、0.2mm、0.15mm等。同时,间隙500中其余结构件43的高度也需符合上述要求,在此不再赘述。
进一步地,请继续参见图19所示。在电路板41的厚度方向上,第一结构件43a的内芯431的高度为h,其中,0.15mm≤h≤0.2mm。由此设置,当第一结构件43a位于母座(第一电子器件421)周围在柔性电路板(第二电子器件422)与基板411之间形成的间隙500中时,第一结构件43a能够取得较高的内芯431厚度收益,在有限的空间中内芯431厚度越大,越有利于降低与其电连接的金属功能层412的阻抗。例如,第一结构件43a内芯431的高度h可以为0.2mm、0.17mm、0.15mm等。且当第一结构件43a的内芯431的高度取最大值0.2mm时,此时第一结构件43a的绝缘层432的最大厚度为0.05mm。同时,间隙500中其余结构件43的内芯431的高度也需符合上述要求,在此不再赘述。
在一些实施例中,请继续参见图18所示。结构件43可以设置有多个,多个结构件43绕第一电子器件421间隔设置。由此设置,能够充分利用第一电子器件421周围在第二电子器件422与基板411之间形成的间隙500,且多个结构件43能够进一步降低电路板41中金属功能层412的阻抗。
其中,多个结构件43可以与同一金属功能层412电连接,也可以分别与不同金属功能层412电连接,本申请对此不作特殊限定。
例如,请继续参见图18、图19所示,其中,结构件43设置有四个,四个结构件43分别为第一结构件43a、第二结构件43b、第三结构件43c和第四结构件43d。在图示方位中,第一结构件43a、第四结构件43d、第二结构件43b和第三结构件43c沿顺时针方向绕第一电子器件421依次分布,并分别通过相应的过孔100与电源层4122电连接。并且,第一结构件43a、第二结构件43b、第三结构件43c和第四结构件43d在第一表面401上的垂直投影完全被第二电子器件422在第一表面401上的垂直投影覆盖,从而在提高基板411第一表面401利用率的同时,还能够进一步降低电源层4122的阻抗。
请参见图20、图21和图22所示,图20为本申请实施例提供的又一种电路板组件40的正视图(沿Z轴负向),图21为图20中M处的局部放大图,图22为图21中N-N处的截面(平行于YZ平面)示意图。在一些情况下,电路板41上需要开设多个沿厚度方向贯穿的开孔200来避让其它电子部件(例如摄像头模组),这就会造成相邻两个开孔200之间形成窄条部分411d,由于窄条部分411d较为细长,无法在此处正常布置元器件42,且该窄条部分411d的结构强度较低,在电路板41受到冲击时极易出现断裂,从而造成基板411上的金属功能层412断裂,导致电路板41失效。
基于此,本申请实施例将第二区域401b设置于相邻的两个开孔200之间。也就是说,相当于结构件43设置在上述窄条部分411d上,这样一来,使得结构件43在降低电路板41中金属功能层412的阻抗的同时,还可以增强该窄条部分411d的结构强度,从而能够降低电路板41在受到冲击或震动时该窄条部分411d出现断裂的风险,进而能够保证电路板41的可靠性和稳定性。
例如,请继续参见图20、图21所示,图20中的电路板组件40相当于是在前述图18中电路板组件40的基板411上开设了三个开孔200,分别为第一开孔200a、第二开孔200b和第三开孔200c。在图示方位中,第一开孔200a、第二开孔200b和第三开孔200c从上到下依次间隔分布,在第一开孔200a和第二开孔200b之间形成第一窄条部分4111,在第二开孔200b和第三开孔200c之间形成第二窄条部分4112。基板411的第一表面401处于第一窄条部分4111上的区域为上部第二区域4013,基板411的第一表面401处于第二窄条部分4112上的区域为下部第二区域4014。
相应的,请继续参见图21、图22所示,还在基板411上增设了两个结构件43,分别为第五结构件43e和第六结构件43f。第五结构件43e设置于上部第二区域4013,从而对第一窄条部分4111进行结构补强。第六结构件43f设置于下部第二区域4014,从而对第二窄条部分4112进行结构补强。并且,第五结构件43e和第六结构件43f分别通过基板411上相应的过孔100与基板411中的电源层4122电连接,从而能够进一步降低电源层4122的阻抗。
同时,在X轴方向上,第五结构件43e的长度大于上部第二区域4013的长度,且第五结构件43e的两端延伸至第一区域401a。此时,相当于第五结构件43e横跨整个第一窄条部分4111,当电路板41受到冲击或震动时,第五结构件43e不仅能够降低第一窄条部分4111的中间位置出现断裂的风险,还能够降低第一窄条部分4111的两端与基板411上第一区域401a对应的部分的连接处出现断裂的风险。
同理,在X轴方向上,第六结构件43f的长度大于下部第二区域4014的长度,且第六结构件43f的两端延伸至第一区域401a,在此不再赘述。
在一些实施例中,请参见图23、图24所示,图23为本申请实施例提供的又一种电路板组件40的正视图(沿Z轴负向),图24为图23中P处的局部放大图。其中,电路板组件40还包括紧固件44,结构件43通过紧固件44固定在电路板41上。由此设置,利用紧固件44不仅能够将结构件43固定的更加牢固,还能够简化结构件43与电路板41之间的装配工序。
例如,请继续参见图23、图24,并结合图25所示,图25为图23中Q-Q处的截面(平行于XZ平面)示意图。图23中的电路板组件40相当于是在上述图20中的电路板组件40上增设了两个第一紧固件44a(均为螺钉)和两个第二紧固件44b(均为螺钉)。其中,第五结构件43e的两端分别开设有第一通孔300a,基板411上开设有与第一通孔300a对应的第一螺孔400a。装配时,只需将第一紧固件44a的一端穿过第一通孔300a后,拧紧在第一螺孔400a中,即可完成对于第五结构件43e的固定。
同理,第六结构件43f的两端分别开设有第二通孔300b,基板411上开设有与第二通孔300b对应的第二螺孔(图25中未示出)。装配时,将第二紧固件44b的一端第二通孔300b后,拧紧在第二螺孔中(此示意图省略),即可完成对于第六结构件43f的固定。

以下是对于又一种结构件43的制造工艺及安装流程说明(以结构件43的内芯431的一侧表面完全露出,内芯431的其余表面均被绝缘层432覆盖,且内芯431为铜片,绝缘层432为贴覆的绝缘膜为例):
