Description
本发明涉及电路板领域,特别涉及一开窗电路板装置及其制造方法以及包埋贴装元器件的电路板装置及其制造方法。
近年来,电子设备越来越朝向轻薄化和智能化的方向发展,这对被配置于电子设备的电路板结构的尺寸和性能都提出了更为苛刻的要求,通常情况下,为了减小电子设备的尺寸,电路板结构的电路板上需要被贴装数量更少和尺寸更小的电子元器件,这与电子设备的智能化的发展方向背道而驰,类似地,为了提高电子设备的智能化水平,电路板结构的电路板上需要被贴装数量更多和尺寸更大的电子元器件,这与电子设备的轻薄化的发展方向背道而驰,因此如何使电子设备同步地朝向轻薄化和智能化方向发展,是电子设备继续发展的技术瓶颈。
具体地说,图1示出了现有技术的电路板结构,其中该电路板结构包括一个电路板10P、一组电子元器件20P以及一个框形的支架30P,每个所述电子元器件20P通过SMT工艺(Surface Mount Technology,表面贴附工艺)被贴装在所述电路板10P的外侧区域,所述支架30P通过一胶水或者类似的粘着物40P被贴装在所述电路板10P的外侧区域,且使所述电路板10P的中部区域通过所述支架30P的通孔与外界环境交流,例如所述电路板10P的中部区域可以通过所述支架30P的通孔与被所述支架30P支撑的元件交流。图1示出的现有技术的所述电路板结构存在着很多的问题。
首先,所述支架30P通过所述胶水或者类似的粘着物40P被贴装在所述电路板10P的外侧区域,一方面,位于所述支架30P和所述电路板10P之间的所述胶水或者类似的粘着物40P增加了所述电路板结构的高度尺寸;另一方面,增加了在所述支架30P和所述电路板10P之间设置所述胶水或者类似的粘着物40P的工序,以至于导致所述电路板结构的成本居高不下;再一方面,通过所述胶水 或者类似的粘着物40P将所述支架30P贴装在所述电路板10P的外侧区域的方式,使得所述支架30P的平整度难以保障。
其次,当每个所述电子元器件20P分别被贴装在所述电路板10P上之后,需要在相邻所述电子元器件20P之间预留足够的距离才能够避免相邻所述电子元器件20P出现相互干扰的不良现象,这导致在有限面积的所述电路板10P上只能够被贴装数量更少和尺寸更小的所述电子元器件20P。
第三,当每个所述电子元器件20P和所述支架30P分别被贴装在所述电路板10P的边缘区域后,无论是在水平方向还是在高度方向都需要在每个所述电子元器件20P和所述支架30P之间预留安全距离H,这成为了限制所述电路板结构的尺寸无法被继续减少的技术瓶颈。
第四,所述支架30P通常是塑料材料制成的塑料件,且所述支架30P的贴装部31P通过所述胶水或者类似的粘着物40P被贴装在所述电路板10P的外侧区域,一方面,受限于所述支架30P的尺寸和材料,在将所述支架30P贴装在所述电路板10P的外侧区域的过程中可能会导致所述支架30P出现变形的不良现象;另一方面,由于所述支架30P的所述贴装部31P与所述电路板10P的接触部位的尺寸比较小,从而当所述支架30P的所述贴装部31P被操作而向所述电路板10P施压时,所述支架30P的所述贴装部31P很容易将所述胶水或者类似的粘着物40P挤压变形,从而导致出现所述胶水或者类似的粘着物40P粘附在所述支架30P的内表面和外表面而污染所述支架30P的不良现象。
另外,在现有技术的所述电路板结构的制造工序中,所述支架30P需要被预制,即首先制得所述支架30P、每个所述电子元器件20P和所述电路板10P,然后再依次将每个所述电子元器件20P贴装在所述电路板10P的外侧区域和将所述支架30P通过所述胶水或者类似的粘着物40P贴装在所述电路板10P的外侧区域,这导致制造工序被增加且在制造所述电路板结构的工序中,对各个部件的管控也变得更为复杂。
另外,电路板在电子设备中不仅起着连接各个电子元器件的作用,而且电路板还允许各个电子元器件被贴装或者被组装在电路板表面,以藉由电路板支撑各个电子元器件。另外,在一些情况下,电路板还被要求保证被贴装或者被组装在电路板表面的各个电子元器件的平整度,这对电路板的强度和平整度也提出了非常苛刻的要求。为了保证电路板的强度和平整度,现在应用于电子设备且被用于 贴装或者组装电子元器件的电路板都是选用强度更高且平整度更好的PCB电路板,然而,这种PCB电路板的厚度尺寸往往比较大。随着近年来电子设备越来越朝向轻薄化的方向和高性能的方向发展,电子设备不仅要求在保证电路板的强度和平整度的基础上减少电路板的尺寸,而且还要求电路板的表面能够被集成或者被连接更多的电子元器件。
通常情况下,各个电子元器件是通过SMT工艺(Surface Mount Technology,表面贴装工艺)被贴装在电路板的表面,这要求各个电子元器件在空间上不能够相互重叠,且相邻电子元器件之间需要预留安全距离,以避免在将各个电子元器件贴装在电路板表面的过程中,各个电子元器件因相互碰触而导致电子元器件接触不牢的不良现象出现,和避免在电子设备被使用时,各个电子元器件因距离过近而出现相互干扰的不良现象,以至于导致在有限面积的电路板上只能够被贴装少数量和小尺寸的电子元器件。
现有技术的采用SMT工艺将各个电子元器件贴装在电路板的表面具有以下缺陷。首先,为了提高电子设备的性能,需要在电路板上贴装更多数量和更大尺寸的电子元器件,这必然导致电路板的尺寸被增加,这与电子设备的轻薄化的发展趋势背道而驰。其次,为了满足电子设备的轻薄化的发展趋势,必然要求电路板被贴装更少数量和更小尺寸的电子元器件,这与电子设备的高性能的发展趋势背道而驰。第三,各个电子元器件大多是通过胶水或者类似的粘着物被贴装在电路板表面,胶水或者类似的粘着物一方面会增加被贴装有电子元器件的电路板的尺寸,另一方面后贴装的电子元器件所需的胶水或者类似的粘着物会污染先贴装的电子元器件,以至于对被贴装有电子元器件的电路板的性能造成不良影响。另外,各个电子元器件大多是通过胶水或者类似的粘着物被贴装在电路板表面,从而在将各个电子元器件封装在电路板表面的过程中,会有一道施胶工序,这不仅增加了在电路板上贴装各个电子元器件的材料成本,而且因增加了在电路板上贴装各个电子元器件的工序而增加了在电路板上贴装各个电子元器件的制造成本。

以下描述用于揭露本发明以使本领域技术人员能够实现本发明。以下描述中的优选实施例只作为举例,本领域技术人员可以想到其他显而易见的变型。在以下描述中界定的本发明的基本原理可以应用于其他实施方案、变形方案、改进方案、等同方案以及没有背离本发明的精神和范围的其他技术方案。
本领域技术人员应理解的是,在本发明的揭露中,术语“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”等指示的方位或位置关系是基于附图所示的方位或位置关系,其仅是为了便于描述本发明和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此上述术语不能理解为对本发明的限制。
可以理解的是,术语“一”应理解为“至少一”或“一个或多个”,即在一个实施例中,一个元件的数量可以为一个,而在另外的实施例中,该元件的数量可以为多个,术语“一”不能理解为对数量的限制。
实施例一:
参考本发明的说明书附图之图2至图8,依本发明的一较佳实施例的一开窗电路板装置在接下来的描述中将被阐述,其中所述开窗电路板装置包括一电路板部10和一开窗形成部20。
所述电路板部10具有一结合区域111和至少一交流区域112。
在附图2示出的所述开窗电路板装置的这个示例中,所述电路板部10包括 一个所述结合区域111和两个所述交流区域112。两个所述交流区域112相互独立。所述结合区域111的一部分位于所述电路板部10的外侧边缘,所述结合区域111的另一部分位于所述电路板部10的中部,以分隔两个所述交流区域112。也就是说,每个所述交流区域112的四周均是所述结合区域111。尽管如此,本领域的技术人员可以理解的是,所述电路板部10也可以具有一个所述交流区域112或者具有三个或者三个以上的所述交流区域112,因此,在附图2至图8中示出的具有两个所述交流区域112的所述电路板部10仅为一个示例性的说明,以被用于阐述本发明的所述开窗电路板装置的特征和优势,因此,在附图2至图8中示出的所述开窗电路板装置的具体示例并不应被视为对本发明的所述开窗电路板装置的内容和范围的限制。
所述开窗形成部20一体地结合于所述电路板部10的所述结合区域111,且所述开窗形成部20在一体地结合于所述电路板部10的所述结合区域111的同时形成至少一开窗21。所述开窗形成部20的每个所述开窗21分别对应于所述电路板部10的每个所述交流区域112,以使所述电路板部10的每个所述交流区域112能够分别通过所述开窗形成部20的每个所述开窗21与外界环境交流。

值得一提的是,在本发明的所述开窗电路板装置的一个示例中,所述保护框30可以被预制,然后将所述保护框30设置于所述电路板11的所述交流区域112的外侧部。在本发明的所述开窗电路板装置的另一个示例中,所述保护框30也可以一体地形成于所述电路板11的所述交流区域112的外侧部,例如可以将胶水施凃于所述电路板11的所述交流区域112的外侧部,以在胶水固化后形成位于所述电路板11的所述交流区域112的外侧部的所述保护框30。
本领域的技术人员可以理解的是,尽管在附图25和图26中示出了所述保护框30位于所述电路板11的所述交流区域112的示例,当所述保护框30位于所述电路板11的所述结合区域111时,也属于本发明定义的所述保护框30位于所述电路板11的所述交流区域112的外侧部。
附图27示出了本发明的所述开窗电路板装置的第十九个变形实施方式,其中所述保护框30也可以同时形成于所述电路板11和所述半导体元件13。具体 地说,在将所述半导体元件13贴装于所述电路板11的所述交流区域112后,将所述保护框30同时设置于或者使所述保护框30同时形成于所述电路板11和所述半导体元件13,以藉由所述保护框30封闭产生于所述电路板11和所述半导体元件13之间的缝隙,从而在后续模制所述开窗形成部20的过程中,所述保护框30能够阻止所述成型材料经由产生于所述电路板11和所述半导体元件13之间的缝隙进入所述电路板11和所述半导体元件13之间,通过这样的方式,能够进一步保证所述半导体元件13的平整度。
附图28示出了本发明的所述开窗电路板装置的第二十个变形实施方式,其中所述保护框30也可以位于所述半导体元件13的外侧部,在后续,所述开窗形成部20可以包覆所述保护框30的至少一部分,以使所述开窗形成部20、所述半导体元件13和所述电路板11一体地结合,从而在模制所述开窗电路板装置时,所述保护框30能够保护所述半导体元件13。
依本发明的另一个方面,本发明进一步提供一开窗电路板装置的制造方法,其中所述制造方法包括如下步骤:
(a)使一电路板11的一结合区域111位于一成型模具100的一成型空间103,和阻止所述电路板11的至少一交流区域112连通于所述成型空间103;
(b)向所述成型空间103内加入成型材料,以使所述成型材料填充满所述成型空间103;以及
(c)使填充在所述成型空间103的所述成型材料固化,以形成一体地形成于所述电路板11的所述结合区域111的一开窗形成部20,和在对应于所述电路板11的每个所述交流区域112的位置形成一开窗21,其中每个所述交流区域112分别通过每个所述开窗21与外界环境交流。
实施例二:
参考本发明的说明书附图之图29至图34B,依本发明的一较佳实施例的一电路板装置被阐述,其中所述电路板装置包括一电路板部40和一包埋部50,所述包埋部50与所述电路板部40一体地结合,以使所述包埋部50包埋所述电路板部40的至少一部分。
值得一提的是,尽管在附图29至图34B示出的本发明的所述电路板装置中,所述包埋部50仅包埋所述电路板部40的外侧边,而在所述电路板装置的其他示例中,所述包埋部50也可以全部包埋所述电路板部40,因此,附图29至图34B 示出的所述电路板装置仅为一个举例性的说明,以用于阐述本发明的所述电路板装置的特征和优势,从而,附图29至图34B示出的所述电路板装置并不应被视作对本发明的所述电路板装置的内容和范围的限制。
进一步地,参考附图34A和图34B,所述电路板部40包括一电路板41和至少一贴装元器件42,其中每个所述贴装元器件42分别被贴装于所述电路板41,所述包埋部50和所述电路板41一体地结合,且所述包埋部50包埋至少一个所述贴装元器件42,以形成所述电路板装置,通过这样的方式,一方面,所述包埋部50通过包埋所述贴装元器件42的方式形成所述电路板装置,能够避免所述包埋部50从所述电路板41上脱落的不良现象,另一方面,所述包埋部50通过包埋所述贴装元器件42的方式形成所述电路板装置,能够避免所述贴装元器件42长时间与空气接触而导致所述贴装元器件42的表面出现氧化的不良现象。也就是说,所述包埋部50能够将所述贴装元器件42封闭起来,以阻止所述贴装元器件42和空气接触。
所述贴装元器件42可以是驱动器、继电器、处理器、电阻、电容等贴装元器件,其通过SMT工艺(Surface Mount Technology,表面贴装工艺)被贴装于所述电路板41。优选地,所述包埋部50包埋相邻的所述贴装元器件42,以藉由所述包埋部50隔离所述贴装元器件42,通过这样的方式,即便是相邻所述贴装元器件42的距离较近时,所述包埋部50也能够避免相邻所述贴装元器件42出现相互干扰的现象。更优选地,所述包埋部50包埋全部的所述贴装元器件42。
优选地,所述包埋部50可以是一个不透光部,所述贴装元器件42被所述包埋部50包埋,从而藉由所述包埋部50阻止外界光线透过所述包埋部50而干扰所述贴装元器件42。
在所述贴装元器件42被贴装于所述电路板41后,所述包埋部50一体地形成于所述电路板41且包埋所述贴装元器件42,从而在所述包埋部50和所述贴装元器件42之间不需要预留安全距离,通过这样的方式,能够减小所述电路板装置的尺寸,尤其是降低所述电路板装置的高度尺寸,以使所述电路板装置特别适用于轻薄化的电子设备。
在所述包埋部50和所述贴装元器件42之间不需要预留安全距离,并且所述包埋部50在成型后分别单独地包埋每个所述贴装元器件42,以用于使相邻且距离较近的所述贴装元器件42不会出现相互干扰的不良现象,因此,在有限面积 的所述电路板41上,可以被贴装更多数量和更大尺寸的所述贴装元器件42,这样,能够在减小所述电路板装置的尺寸的基础上,进一步提高所述电路板装置的性能,这是现有技术意料不到的,并且对于应用所述电路板装置的电子装置的轻薄化和高性能的发展趋势特别的有用。
附图29至图34B示出了所述电路板装置的制造步骤且示出了所述电路板装置的剖视状态和立体状态。
附图29示出了所述电路板41的俯视角度,其中所述电路板41可以是一个印刷电路板。具体地说,所述电路板41包括一基板411和至少一电路412,其中所述电路412通过印刷的方式形成在所述基板411的表面,被贴装于所述电路板41的所述贴装元器件42被导通地连接于所述电路板41的所述电路412。本领域的技术人员可以理解的是,采用印刷的方式使所述电路412形成于所述基板411的方式使所述电路412突出于所述基板411的表面。尽管如此,本领域的技术人员可以理解的是,在本发明的所述电路板装置的其他示例中,所述电路板41也可以不是印刷电路板,而是其他类型的电路板,例如蚀刻电路板。
在本发明的这个示例中,所述电路412呈环形地形成于所述基板411的外侧边缘,以使所述电路板41在所述电路412的两侧分别形成一外侧区域413和一内侧区域414,即,所述电路板41的所述外侧区域413和所述内侧区域414分别位于所述电路412的两侧。
尽管在附图29中示出了的所述电路板41的所述电路412呈完整的环形形成于所述基板411的外侧边缘,本领域的技术人员可以理解的是,所述电路412也可以具有其他的形态,例如所述电路412形成的环形可以设有开口,或者所述电路412没有形成环形,因此,附图29中示出的所述电路板41的呈环形的所述电路412并不作为对本发明的所述电路板装置的内容和范围的限制。
参考附图30A和图30B,将每个所述贴装元器件42相互间隔地贴装于所述电路板41,且每个所述贴装元器件42分别被导通地连接于所述电路板41的所述电路412。优选地,每个所述贴装元器件42分别通过SMT工艺被贴装于所述电路板41。更优选地,每个所述贴装元器件42均位于所述电路板41的所述外侧区域413,从而使所述电路板41的所述内侧区域414保持平整。
参考附图31A,将贴装有所述贴装元器件42的所述电路板41放置在一成型模具100的一成型空间103内,以藉由所述成型模具100使被加入所述成型空间 103的呈流体状态的一成型材料形成与所述电路板41一体结合的所述包埋部50。
具体地说,所述成型模具100包括一上模具101和一下模具102,其中所述上模具101和所述下模具102中的至少一个能够被操作,以使所述成型模具100的所述上模具101和所述下模具102被执行合模或者拔模的操作,并且当所述上模具101和所述下模具102被合模时,在所述上模具101和所述下模具102之间形成至少一个所述成型空间103,以用于模制所述电路板装置。
值得一提的是,尽管在附图31A中示出了在所述成型模具100的所述上模具101和所述下模具102之间形成一个所述成型空间103的实施方式,本领域的技术人员可以理解的是,在其他的示例中,在所述成型模具100的所述上模具101和所述下模具102之间还可以形成两个或者两个以上的所述成型空间103,以供同时模制两个或者两个以上的所述电路板装置。
在所述上模具101和所述下模具102被合模后,所述上模具101的施压面1011施压于所述电路板41的所述电路412上,以使所述电路板41的所述内侧区域414处于封闭状态,从而在后续模制所述电路板装置的过程中,能够避免所述成型材料进入所述电路板41的所述内侧区域414而污染所述内侧区域414。
附图31B示出了所述成型模具100的另一个实施方式,其中所述成型模具100还可以包括一覆盖膜104,其中所述覆盖膜104被重叠地设置在所述上模具101的所述施压面1011,以在所述上模具101和所述下模具102被执行合模操作时,藉由所述覆盖膜104隔离所述上模具101的所述施压面1011和所述电路板41,从而通过防止所述上模具101的所述施压面1011直接接触所述电路板41的方式保护所述电路板41的所述电路412在模制所述电路板装置的过程中不被破坏。优选地,所述覆盖膜104可以通过被贴附于所述上模具101的所述施压面1011的方式被重叠地设置于所述施压面1011。
另外,所述覆盖膜104可以具有缓冲能力,从而在所述上模具101和所述下模具102被执行合模操作且在所述上模具101接触所述电路板41时产生的冲击力能够被位于所述上模具101的所述施压面1011和所述电路板41之间的所述覆盖膜104吸收,从而避免该冲击力直接作用于所述电路板41,以进一步保护所述电路板41的所述电路412。
在所述上模具101的所述施压面1011施压于所述电路板41时,所述覆盖膜104能够密封产生于所述上模具101的所述施压面1011和所述电路板41之间的 缝隙,以避免呈流体状的所述成型材料通过形成于所述上模具101的所述施压面1011和所述电路板41之间的缝隙进入所述电路板41的所述内侧区域414而污染所述内侧区域414的不良现象,且能够避免“飞边”的不良现象。另外,所述覆盖膜104还能方便对所述成型模具100执行拔模。
尽管在接下来的描述中仍以所述成型模具100没有被配置所述覆盖膜104为例来阐述本发明的所述电路板装置的制造步骤,本领域的技术人员可以理解的是,在附图32和附图33中,所述成型模具100也可以被配置所述覆盖膜104。
参考附图32和图33,将流体状的所述成型材料加入所述成型模具100的所述成型空间103中,由于填充在所述成型空间103的所述成型材料受到所述电路板41的所述电路412的阻挡,从而使所述成型材料在固化后仅在所述电路板41的所述外侧区域413与所述电路板41的一部分一体结合的所述包埋部50,且在所述电路板41的所述内侧区域414对应的部位形成所述包埋部50的一开窗51。也就是说,在所述包埋部50一体地形成于所述电路板41的一部分后,所述电路板41的另一部分可以通过所述包埋部50的所述开窗51与外界环境交流。
值得一提的是,呈流体状的所述成型材料可以是液体或者固体小颗粒或者液体与固体小颗粒的混合物,本发明的所述电路板装置在这方面不受限制,其能够在被加入所述成型模具100的所述成型空间103后充斥整个所述成型空间103且在固化形成后在常温状态下具有良好的稳定性即可。例如所述成型材料可以是热固性材料。

附图36示出了本发明的所述电路板装置的第二个变形实施方式,其中所述电路板部40包括一半导体元件43,其中所述半导体元件43被导通地连接于所述电路板41,并且所述半导体元件43对应于所述包埋部50的所述开窗51,以藉由所述半导体元件43通过所述包埋部50的所述开窗51与外界环境交流。优选地,所述半导体元件43被贴装于所述电路板41的所述内侧区域414,以保证所述半导体元件43的平整度,并且使所述半导体元件43能够被直接导通地连接于所述电路板41或者所述半导体元件43通过其他的部件被导通地连接于所述电路板41。

具体地说,在藉由所述成型模具100模制所述电路板装置时,所述成型模具100的所述下模具102支撑所述电路板41的边缘区域,从而在所述电路板41的下表面和所述下模具102的内表面可以形成一辅助成型空间,所述辅助成型空间通过所述电路板41的呈通孔状的每个所述定位空间417连通于所述成型空间103。
