Description

摄像模组的模塑电路板及其制造设备和制造方法 技术领域
本发明涉及摄像模组的电路板,尤其涉及摄像模组的模塑电路板及其制造设备和制造方法。
背景技术
随着各种电子产品、智能设备的发展,摄像模组也越来越向高性能、轻薄化方向发展,而面对高像素、高成像质量等各种高性能的发展要求,电路中的电子元器件越来越多、芯片的面积越来越大、驱动电阻、电容等被动元器件相应增多,这使得电子器件的规格越来越大、组装难度不断增大、摄像模组的整体尺寸越来越大,而从上述来看,镜座、线路板以及电路元件等的传统组装方式在一定程度上也是摄像模组轻薄化发展的极大限制。
传统的摄像模组一般包括电路板,感光元件,镜座,镜头等部件,其封装一般采用COB(Chip On Board)工艺,其中该感光元件连接于该电路板,该镜座通过胶水贴附于该电路板,然而这种封装工艺中,粘贴所述镜座时,该镜座位于该电路板的这些电子元器件的外侧,因此在安装该镜座和该电路板时,需要在该镜座和这些电子元器件之间预留一定的安全距离,且在水平方向以及向上的方向都需要预留安全距离,这在一定程度上增大了摄像模组厚度的需求量,使其厚度难以降低。
另外,该镜座或马达通过胶水等粘贴物粘贴于该电路板,在粘贴时通常要进行校准工艺,就是调整该感光元件和该镜头的中心轴线,使其达到水平方向和竖直方向的一致,因此为了满足校准工艺,需要在该镜座与该电路板以及该镜座与该马达之间都需要预设较多的胶水,使得相互之间留有调整空间,而这个需求一方面在一定程度上又增加了对摄像模组的厚度需求,使其厚度难以降低,另一方面,多次粘贴组装过程很容易造成组装的倾斜不一致,且对该镜座、该电路板以及该马达的平整性要求较高。使用胶水粘接不能保证该镜座平整地贴附于该电路板。
并且在贴附和封装过程中该电路板的这些电子元器件和该感光元件都暴露在环境中,不可避免会有污尘等容易黏着于该电路板的这些电子元器件上,或甚至进一步地到达该感光元件上,从而可能造成组装后的摄像模组存在污黑点等不良现象,降低了产品良率。
通过在该电路板上将该镜座一体封装成型,可以解决上述问题,但现有技术中还没有这样的具有一体封装成型的镜座的电路板,也没有合适的封装设备。传统的半导体一体封装成型工艺中,一般是通过液体材料一体封装在整个半导体基板上,液体材料能够大面积地包覆于整个半导体材料,然后固化成形完成封装。
然而,受限于该摄像模组的电路板及其镜座结构,传统半导体封装工艺还没有应用于制作这样的具有一体封装成型的镜座的电路板。一方面,摄像模组对尺寸、精度和平整性的要求更高。另一方面,该电路板需要搭配该感光元件,该镜座一般是呈环形,中间需要设置光窗,以方便该感光元件和该镜头光学地对齐排列并且使穿过该镜头的光线经过该光窗到达该感光元件,并且该镜座的底侧需要与该电路板紧密无缝地结合,除了该光窗,该镜座的其他侧面需要遮光即阻挡杂光进入,而现有的一体封装设备还没有能够形成具有这样光学特性的镜座的设计,尤其是没有一体封装成型的成型模具。
更细节地,在设计该镜座成型模具的过程中,需考虑如何为该感光元件的感光区域建立稳定的隔离环境,以确保在该镜座模塑成型的过程中模塑成型材料不会进入该感光元件进而出现飞边或者该感光元件发生污染等不良工艺。此外,该感光元件通常具有较薄的厚度以及较脆的性质,因此在为该感光元件设计隔离措施的过程中,需确保该感光元件不会承受过重的压力而被压碎。此外,通常在该感光元件和该电路板之间会设有一引线,其中该引线在该感光芯片和该电路板之间弯曲地延伸以导通该线路板和该感光芯片。相应地,在为该感光芯片设计隔离措施的过程中,需进一步为该引线预留空间,以防止在为该感光芯片建立隔离环境中,该引线受压变形甚至出现从该感光元件和该电路板上脱离的现象。
再一方面,该摄像模组的该电路板上通常有多种电子元器件,如电阻、电容和驱动等,这种一体封装工艺需要对这些电子元器件进行合理的排布,并且将成型模具的成型结构设计成只能在电路板的周边位置上形成这样的具有光窗的镜座,而不能进入电路板与该感光元件的有效感光区域内而影响感光效果。另外,成型模具也需要设计成能够形成与该电路板尺寸如面积、厚度等搭配,从而形成 具有合适尺寸的该镜座。

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。
如图1至图13所示是根据本发明的一个优选实施例的一摄像模组100的一 模塑电路板10及其制造设备200。如图10至图13所示,所述模塑电路板包括一电路板11以及一模塑基座12,其中本发明的所述模塑基座12通过所述制造设备200一体封装成型于所述电路板11上,从而所述模塑基座12能够替换传统摄像模组的镜座或支架,并且不需要类似传统封装工艺中需要将镜座或支架通过胶水贴附于线路板。
所述摄像模组100进一步地包括一感光元件20和一镜头30。其中所述模塑基座12包括一环形模塑主体121、并且中间具有一光窗122,以给所述镜头30与所述感光元件20提供一光线通路。所述感光元件20可工作地连接于所述电路板11,如通过COB打引线的方式将所述感光元件20连接于所述电路板11并位于所述电路板11的顶侧,或者通过倒装方式(Flip Chip)将所述感光元件20设置于所述电路板11的底侧。所述感光元件20和所述镜头30分别组装于所述模塑基座12的两侧,并且光学对齐地排列,使穿过所述镜光30的光线能够经由所述光窗122到达所述感光元件,从而经过光电转化作用后能够使所述摄像模组100得以提供光学图像。
所述摄像模组100可以是定焦摄像模组,或者是动焦摄像模组。如图12和所13中所示,所述摄像模组100可以是具有一马达40(驱动器)的动焦摄像模组,所述镜头30安装于所述马达40。所述模塑基座12可以用于支撑所述马达40。所述模塑基座12的顶侧还可以设置有一滤光片50,以用于过滤穿过所述镜头30的光线,如可以是红外截止滤光片。
所述电路板11包括一基板111,以及形成于所述基板111如通过SMT工艺贴装的多个电子元器件112,所述电子元器件112包括但不限于电阻、电容、驱动器件等。在本发明的这个实施例中,所述模塑基座12一体地包覆于所述电子元器件112,从而防止类似传统摄像模组中灰尘、杂物粘附在所述电子元器件112上,并且进一步地污染所述感光元件20,从而影响成像效果。可以理解的是,在另外的变形实施例中,也有可能所述电子元器件112内埋于所述基板111,即所述电子元器件112可以不暴露在外。所述电路板111的基板111可以是PCB硬板、PCB软板、软硬结合板、陶瓷基板等。值得一提的是,在本发明的这个优选实施例中,因为所述模塑基座12可以完全包覆这些电子元器件112,所以电子元器件112可以不内埋于所述基板111,所述基板111只用于形成导通线路,从而使得最终制得的所述模塑电路板10得以厚度更小。
在本发明的这个优选实施例中,如图10至图13所示,所述基板111包括一中央的芯片叠合区域111a,以对应于相叠合的所述感光元件20,在所述中央的芯片叠合区域111a的周围形成一边缘区域111b,所述电子元器件112可以布置于所述边缘区域111b,从而提供一个相对较为平整的所述中央的芯片叠合区域111a,以方便模塑时,所述基板111的所述中央的芯片叠合区域111a与所述制造设备的模具表面紧密贴合,防止模塑材料13进入所述中央的芯片叠合区域111a,在下文中将进一步具体地描述。
可以理解的是,本发明的所述模塑基座12通过模塑工艺固定于所述电路板11,不需要粘贴固定过程,模塑方式相对于粘贴固定具有更好的连接稳定性以及工艺过程的可控性,且在所述模塑基座12与所述电路板11之间不需要预留校准调整的胶水空间,使得摄像模组的厚度得以减小;另一方面,所述模塑基座12包覆所述电子元器件112,从而不需要像传统摄像模组,在电子元器件周围预留安全距离。此外,所述模塑基座12代替传统的镜座或支架,避免了镜座或支架在粘贴组装时带来的倾斜误差,减小了摄像模组组装的累积公差。而且所述模塑基座12一体成形于所述电路板11,从而一体紧密结合的结构能够使所述模塑基座12阻挡杂光,加强所述电路板11的散热功能,以及增强所述模塑电路板11的强度。
更进一步地,如图1至图9所示,所述摄像模组100的所述模塑电路板10的制造设备200包括一成型模具210,一模塑材料供料机构220,一模具固定装置230,一温控装置250和一控制器260,所述控制器260在模塑工艺中用于自动控制所述模塑材料供料机构220。所述成型模具210包括在所述模具固定装置230的作用下能够开模和合模的一第一模具211和一第二模具212,即所述模具固定装置230能够将所述第一模具211和所述第二模具212相分开和相密合形成一成型腔213,在合模时,所述电路板11固定于所述成型腔213内,并且液体状的所述模塑材料13进入所述成型腔213,从而一体成型于所述电路板11上,并且经固化以后形成一体成型于所述电路板11上的所述模塑基座12。
更具体地,所述成型模组210进一步地包括一光窗成型块214以及具有形成在所述光窗成型块214周围的一基座成型导槽215,在所述第一和第二模具211和212合模时,所述光窗成型块214和所述基座成型导槽215延伸在所述成型腔213内,并且液体状的所述模塑材料13被填充进入所述基座成型导槽215,而对 应所述光窗成型块214的位置不能填充液体状的所述模塑材料13,从而在对应所述基座成型导槽215的位置,液体状的所述模塑材料13经固化以后可以形成所述模塑基座12的环形的模塑主体121,而在对应所述光窗成型块214的位置会形成所述模塑基座12的所述光窗122。
所述第一和第二模具211和212可以是能够产生相对移动两个模具,如两个模具中的其中一个固定,另一个可移动;或者两个模具都可移动,本发明在这方面并不受到限制。在本发明的这个实施例的示例中,所述第一模具211具体地实施为一固定上模,而所述第二模具212实施为一可移动下模。所述固定上模和所述可移动下模共轴地设置,如所述可移动下模可以沿着多个定位轴向上滑动,在与所述固定上模合模时能够形成紧密闭合的所述成型腔213。
所述第二模具212即所述下模可以具有一电路板定位槽2121,用于安装和固定所述电路板11,而所述光窗成型块214和所述基座成型导槽215可以形成在所述第一模具211,即形成在所述上模,当所述第一和第二模具211和212合模时,形成所述成型腔213。并且液体状的所述模塑材料13注入至所述电路板11的顶侧的所述基座成型导槽215,从而在所述电路板11的顶侧形成所述模塑基座12。
可以理解的是,所述电路板定位槽2121也可以设置于所述第一模具211即所述上模,用于安装和固定所述电路板11,而所述光窗成型块214和所述基座成型导槽215可以形成在所述第二模具211,当所述第一和第二模具211和212合模时,形成所述成型腔213。所述电路板11在所述上模中可以正面朝下地布置,并且液体状的所述模塑材料13注入至倒置的所述电路板11的底侧的所述基座成型导槽215,从而在倒置的所述电路板11的底侧形成所述模塑基座12。
更具体地,在所述第一和第二模具211和212合模并执行模塑步骤时,所述光窗成型块214叠合于所述电路板11的所述基板111的中央的芯片叠合区域111a,并且所述光窗成型块214的底表面与所述电路板11的所述基板111的中央的芯片叠合区域111a紧密贴合,从而液体状的所述模塑材料13被阻止进入所述电路板11的所述基板111的中央的芯片叠合区域111a,从而在对应所述光窗成型块214的位置能够最终形成所述模塑基座12的所述光窗122。而所述基座成型导槽215的位置在所述边缘区域111b,这样当所述基座成型导槽215中填充液体状的所述模塑材料13时,液体状的所述模塑材料13一体结合于所述电路板11的所 述基板111的所述边缘区域111b,并且在固化后能够在所述电路板11的所述基板111的中央的芯片叠合区域111a的外侧形成所述模塑基座12。
可以理解的是,在这个实施例中,所述电路板11的所述电子元器件112可以被布置于所述中央的芯片叠合区域111a之外,即对应安装所述感光元件20的位置之外,这样所述中央的芯片叠合区域111a的位置没有凸起的所述电子元器件112,从而所述电路板11的所述基板111的中央的芯片叠合区域111a可以提供一个较为平整的表面,这样当设置于所述第一模具211的所述光窗成型块214贴合于所述电路板11的所述基板111的中央的芯片叠合区域111a时,所述光窗成型块214的底表面与所述电路板11的所述基板111的中央的芯片叠合区域111a之间不会因为有凸起而形成间隙而导致在模塑过程中时液体状的模塑材料13进入所述电路板11的所述基板111的中央的芯片叠合区域111a。即所述光窗成型块214的底表面能够与所述电路板11的所述基板111的中央的芯片叠合区域111a的顶表面之间紧密贴合,从而液体状的所述模塑材料13只能到达所述光窗成型块214的周围,以防止造成飞边现象。也可以说,所述电路板11的所述基板111的中央的芯片叠合区域111a提供了与所述光窗成型块214的底表面紧密贴合的接合面。
并且,在所述成型模具210合模时,所述电子元器件112进入所述基座成型导槽215内,这样液体状的所述模塑材料13进入所述基座成型导槽215时,液体状的所述模塑材料13包覆在各个所述电子元器件112的表面,
值得一提的是,所述光窗成型块214进一步包括一成型部主体2141以及顶端的与所述成型部主体一体成型的一台阶部2142。这样所述模塑基座12在所述光窗112的顶端还可以形成一凹槽123,使所述模塑基座12形成台阶状的顶表面。当然在其他实施例中,所述模塑基座12在所述光窗112的顶端也可以没有上述凹槽123,而是形成平整的顶表面。本发明的这个实施例中形成的所述凹槽123内可以直接用来安装所述滤光片50,即所述模塑基座12内侧的台阶顶表面可以用来支撑所述滤光片50,也可以用来安装镜头30,而外侧的台阶顶表面可以用来安装所述马达40或安装其他用来支撑所述镜头30的部件,或直接用来支撑所述镜头30。或者,所述凹槽123的位置进一步地贴装有一小支架,所述小支架用来安装所述滤光片50或马达镜头。另外,所述模塑基座12的所述光窗122的形状不受到限制,在示意的示例中,所述光窗122可以呈方形或圆形,所 述光窗成型块214相应地可以呈柱状结构。在另外的变形中,如可以是具有渐大直径的锥台。
可以理解的是,所述第一模具211形成所述基座成型导槽215的成型面可以构造成平整面,并且处于同样的平面,这样当所述模塑基座12固化成型时,所述模塑基座12的顶表面较为平整,从而为所述马达40,所述镜头30或所述镜头的其他承载部件提供平整的安装条件,减小组装后的所述摄像模组100的倾斜误差。
值得一提的是,所述基座成型导槽215和所述光窗成型块214可以一体地成型于所述第一模具211。也可以是,所述第一模具211进一步地包括可拆卸的成型结构,所述成型结构形成有所述基座成型导槽215和所述光窗成型块214。这样,根据不同的所述模塑电路板10的形状和尺寸要求如所述模塑基座的直径和厚度等,可以设计不同形状和尺寸的所述基座成型导槽215和所述光窗成型块214。这样,只需要替换不同的成型结构,即可以使所述制造设备适合应用于不同规格要求的所述模塑电路板10。可以理解的是,所述第二模具212相应地也可以包括可拆卸的固定块,以提供不同形状和尺寸的所述凹槽2121,从而方便更换适应不同形状和尺寸的所述电路板11。
所述模塑材料供料机构220包括一储料器221,一推料器222,一熔化加热装置251,并且具有一送料通道223。所述送料通道223与所述基座成型导槽215相连通。所述储料器221具有一储料槽2211,所述模塑材料13可以放置于所述储料槽2211中,通过所述熔化加热装置251将呈固态的所述模塑材料13加热熔化变成液体状的所述模塑材料13。所述储料器221可以是单独的盒体,也可以一体成型于所述第二模具212,即所述储料槽2211可以一体形成于所述第二模具212的局部位置。所述送料通道223可以一体地形成在模塑材料供料机构220内,或者通过合适的连通于所述储料槽2211的送料导管形成,在这个优选实施例中,所述送料通道223实施为形成于所述第一模具211或所述第二模具212如所述第一模具211即上模的底侧的导引槽,在所述第一和第二模具211和212合模时,所述导引槽得以可以形成向所述基座成型导槽215输送所述模塑材料13的所述送料通道223。可以理解的是,在完成模塑成型工艺后,所述送料通道223内也将形成由所述模塑材料13成型的固化延伸段。在取出成型后的产品后,所述送料通道223和所述基座成型导槽215可以根据需要进行清选。所述推料器 222可以为可活动的能够对所述储料槽2211中所述模塑材料13加压并推动的结构,例如可以是一柱塞或一螺杆。所述熔化加热装置251可以是各种可以将所述储料槽2211中的固态的所述模塑材料13进行加热的合适结构,例如在一个例子中,可以是在所述储料器221的外侧具有加热管道,所述加热管道中填充有加热流体或电热器件。
可以理解的是,所述模塑材料13还可以经过称重,而对进入所述基座成型导槽215的液体状的所述模塑材料13精确定量。或者所述模塑材料供料机构220还可包括定量分配机构,如通过所述模塑材料13的流速以及所述送料通道223的直径来计算填充至所述基座成型导槽215的液体状的所述模塑材料13的量。或者,通过保持所述成型模具210的所述基座成型导槽215内的压力,从而控制所述模塑材料13的量。当然这里的定量控制方式,也可以不限于上述方式而可以采用其他合适的方式。
在所述成型模具210处于合模状态时,经过所述推料器222的推动加压作用,液体状的所述模塑材料13被推动通过所述送料通道223进入所述基座成型导槽215,从而填充在所述光窗成型块214的周围。最后,液体状的所述模塑材料13经过一个固化过程,使位于所述基座成型导槽215的液体状的所述模塑材料13固化和硬化从而形成一体模塑于所述电路板11的所述模塑基座12。
可以理解的是,所述模塑材料13可以是热熔性材料如热塑性塑料材料,通过所述熔化加热设备将呈固态的热熔性材料加热熔化变成液体状的所述模塑材料13。在所述模塑成型的过程中,热熔性的所述模塑材料13经过冷却降温过程得以固化成型。所述成型模具210还可以配置有固化温控装置252,其用于为所述成型腔213提供温控环境,对所述基座成型导槽215内的液体熔化状态的所述模塑材料13降温从而使所述模塑材料13固化成型而形成所述模塑基座12。
所述模塑材料13也可以是热固性材料,将呈固态的热固性的所述模塑材料13放入所述储料槽2211中。通过所述熔化加热设备将呈固态的热固性材料加热熔化变成液体状的所述模塑材料13。在所述模塑成型的过程中,热固性的所述模塑材料13经过进一步地加热过程而固化,并且在固化后不再能在原较低熔点熔化,从而形成所述模塑基座12。
相应地,当所述模塑材料13是热固性材料时,所述成型模具210配置的所述固化温控装置252可以是一固化加热装置,以对进入所述基座成型导槽215的 液体状的热固性的所述模塑材料13继续加热,从而使所述液体状的热固性的所述模塑材料13热固成型。可以理解的是,用于加热熔化所述模塑材料13的所述熔化加热设备和用于使所述模塑材料13热固成型的所述固化加热设备可以是单独的加热装置,也可以是一体的加热装置。在使用一体的加热装置时,对所述模塑材料13的熔化加热温度和固化保温温度可保持一致,此时,需要一提的是,在所述储料槽2211中的熔化加热时间需要控制,以避免液体状的所述模塑材料13在所述储料槽2211中固化。从而在固态的所述模塑材料13大致完全熔化为液体状态时,便采用所述推料器222将其推送进入所述送料通道223。或者在固态的所述模塑材料13开始熔化,并呈半固状态时,即可以在边熔化过程中边开始采用所述推料器222将其推送进入所述送料通道223。在熔化和固化采用不同的加热装置时,所述固态的所述模塑材料13可以相对较低的温度环境下加热熔化至液体状态后,再送入较高的温度环境下固化成型。
可以理解的是,所述成型模具210可以对预先固定的所述电路板11预加热,例如可以加热至所述固化过程中的温度,从而在所述模塑成型过程中,所述电路板11和液体状的热固性的所述模塑材料13不会有太大的温差,从而便于液体状的所述模塑材料13紧密结合于所述电路板11的表面。
可以理解的是,在这个实施例中,示意一个所述电路板11的模塑工艺,在应用中,也可以同时对多个独立的所述电路板11进行模塑工艺,即所述储料槽2211中的所述模塑材料13经加热熔化后被同时通过多个所述送料通道223输送至多个独立的所述电路板11以进行模塑成型工艺。或者也可以采用在下文中另一个实施例中提到的拼板作业。
如图5至图9B所示是根据本发明的这个优选实施例的所述摄像模组100的所述模塑基座12的制造过程示意图,其中图5至图9A的剖视图是沿着如图5中示意的B-B线方向的剖视图,图9B是着如图5中示意的C-C线方向的剖视图。

如图8所示,熔化的所述模塑材料13在所述推料器222的作用下,沿着所述送料通道223进入所述基座成型导槽215,并到达所述光窗成型块214的周围。可以理解的是,所述模塑材料13可以全部熔化为液体状态后再被所述推料器222推送入所述送料通道223,也可以是所述模塑材料13在半熔化时就被推送入所述送料通道223,并且藉由所述成型模具210提供有加热环境而使固态的所述模塑材料13全部熔化呈液体状态。
如图9A和9B所示,当所述基座成型导槽215内全部填充有液体状的所述模塑材料13时,再经过固化过程使液体状的所述模塑材料13固化成型为一体成型于所述电路板11的所述模塑基座12。以所述模塑材料13为热固性材料为例,被加热熔化而呈液体状的所述模塑材料13再经过加热过程,从而固化成型。例如可以升温加热,也可以保温加热预定长的时间。例如以保温加热固化为例,在一个具体示例中,固态的所述模塑材料13被在预定温度如175℃的加热环境中加热一第一预定时间而熔化为液体状态,并且在输送至所述基座成型导槽215内时,在该预定温度的加热环境中加热保温一第二预定时间而使液体状的所述模塑材料13固化成型。可以理解的是,这里温度以及第一和和第二预定时间的数值不作为举例,而并不限制本发明。根据所述模塑材料13的材料性质以及模塑成型工艺的要求,在实际应用中可以根据需要而调节。如预定温度是110-250℃,熔化加热时间是2-10秒,固化加热时间是15秒-5分钟等,本发明在这方面并不受限于上述示例中的数值和数值范围。另外,在所述模塑成型工艺结束后,制作得到的所述模塑电路板10可以取出所述成型模具210,并且继续放在烘烤设备中继续加热硬化预定时间如1-5小时。
另外,参照图21,本发明提供一摄像模组100的一模塑电路板10的制造方法,其包括如下步骤:

固化液体状的所述模塑材料13的步骤:在所述成型模具210内,所述基座 成型导槽215内的所述模塑材料13从液体状态转变成固体状态。
可以理解的是,在固定所述电路板11的步骤中,所述成型模具210处于开模状态,所述电路板11可固定于所述成型模具210的所述第二模具212,或者所述电路板11可固定于所述成型模具210的所述第一模具211。在本发明示意的这个实施例中,所述电路板11固定于所述第二模具212,即所述下模212,并且所述电路板11的所述电子元器件112位于顶侧,待在后续模塑成型步骤中被所述模塑材料13一体包覆。
在填充所述模塑材料13的步骤中,根据本发明的这个实施例,其进一步地包括步骤:将固体状的所述模塑材料13在所述成型模具210合模前预先上料至所述储料槽2211内,固体状的所述模塑材料13可以是固体料块,也可以是固体粉末;将固体状的所述模塑材料13熔化并在所述推送器222推动作用下经由所述送料通道223输送进入所述基座成型导槽215。推送操作结束后,呈液体状的所述模塑材料13填满所述基座成型导槽215。
固化液体状的所述模塑材料13的步骤:在所述模塑材料13是热固性材料时,所述成型模具210的所述成型腔213提供有加热环境,这样液体状的所述模塑材料13热固成型而形成一体成型于所述电路板11上的所述模塑基座12,并且所述模塑基座12包覆所述电子元器件112;在所述模塑材料13是热熔性材料时,液体状的所述模塑材料13在所述成型模具210内冷却,从而冷却固化形成一体成型于所述电路板11上的所述模塑基座12。
如图14、15A和15B所示,本领域技术人员可以想到的是,在另外的变形实施方式中,所述电路板11的所述基板111的中央的芯片叠合区域111a可以内凹,即所述电路板11的所述基板111的中央的芯片叠合区域111a和所述边缘区域111b不在同一表面,内凹的所述芯片叠合区域111a使所述电路板11的所述基板111的顶侧可以形成内凹槽113,这样所述光窗成型块214凸于所述基座成型导槽215,并且其底端延伸进入所述内凹槽113,并与内凹的所述芯片叠合区域111a相贴合,从而进一步地防止液体状的所述模塑材料13进入所述内凹槽113并到达所述芯片叠合区域111a。另外,在这样的具有所述内凹槽113的所述电路板11一体地模塑成型所述模塑基座12后,所述感光元件20可以安装于所述内凹槽113内。
另外,上述示例中,在所述模塑基座12一体成型于所述电路板11得到所述 模塑电路板10后,所述感光元件20以COB方式组装于所述模塑电路板10的所述电路板11的顶侧所述模塑基座的内侧。在另外的变形实施方式中,在形成所述模塑基座12以后,并且所述电路板11形成有开孔时,所述感光元件20也可以倒装方式组装于所述电路板11。
如图16A至图16C所示,根据本发明的上述实施例的一种变形实施方式,在本发明的这个变形实施方式中,所述制造模具200可以制造能够不仅包覆在所述电路板11的顶表面的所述模塑基座12。具体地,所述模塑基座12的至少一侧面和至少一部分底面也可以被所述模塑材料13包覆,从而增强所述模塑电路板10的强度,也便于所述模塑电路板10沿着侧面包覆那一侧进行切割得到成品。
如图16B和图16C所示,在所述成型模具210合模时,所述电路板11的至少一侧面具有侧面导槽216,在所述电路板11的背面具有一底侧导槽217,并且所述侧面导槽216和所述底侧导槽217能够和所述送料通道223相连通。这样当液体状的所述模塑材料13通过所述送料通道223进入所述成型模具210内时,其能够填充进入所述基座成型导槽215和所述侧面导槽216以及所述底侧导槽217,这样在经过固化步骤后,所述模塑基座12可以进一步地将所述电路板11的至少一侧面和至少一部分底面包覆。可以理解的是,在另外的变形实施例中,除了形成所述环形基座主体121,也可能是所述模塑基座12只将所述电路板11的至少一侧面包覆,或者只将所述电路板11的至少一部分底面包覆。
另外,所述电路板11的所述基板111还可以进一步地具有一个或多个穿孔114,这样,在模塑成型工艺中,所述液体状的所述模塑材料13可以进一步地填充进入所述穿孔114,以进一步地加强形成的模塑一体结构的强度。在这里的这个示例,所述穿孔114也可以进一步地将所述基座成型导槽215和所述底侧导槽217相导通。可以理解的是,所述穿孔114和所述侧面导槽216可以不必同时存在。
如图17至图19所示,在本发明的另一变形实施方式中,所述制造模具200可以制造能够将所述感光元件20一体封装的具有所述感光元件20的所述模塑电路板10。在这个变形实施方式中,一体成型的所述模塑基座12一体地包覆在所述电路板11和所述感光元件20上。
更具体地,所述感光元件20预先连接于所述电路板11,如通过COB(Chip on Board)的引线连接方式与所述电路板11电性连接。如图17中所示,所述感 光元件20通过一个或多个引线21连接于所述电路板11。并且所述感光元件20在顶表面具有一感光区域201和位于所述感光区域201周围的一非感光区域202,即所述感光区域201位于中央位置,而所述非感光区域202位于所述感光元件20的外边缘位置。
在所述成型模具210开模时,将连接有所述感光元件20的所述电路板11安装于所述第二模具212。如图18至图19所示,在所述成型模具210合模时,连接有所述感光元件20的所述电路板11就位于所述成型模具210的所述成型腔213内。所述光窗成型块214贴合于所述感光元件20的至少所述感光区域201,所述引线21和所述电路板11的所述电子元器件112位于所述基座成型导槽215内。这样当液体状的所述模塑材料13通过所述送料通道223进入所述成型模具210内时,液体状的所述模塑材料13只能到达所述光窗成型块214的周围,即位于所述基座成型导槽215内,即液体状的所述模塑材料13被阻止进入所述感光元件20的所述感光区域201。最后在,所述感光元件20的所述感光区域201的外侧,液体状的所述模塑材料13经固化而形成所述环形基座主体121,即所述环形基座主体121沿着所述感光元件20的环形外边缘一体成型于至少一部分所述非感光区域202。
可以理解的是,所述模塑基座12通过模塑工艺固定于所述电路板11和所述感光元件20,不需要粘贴固定过程,模塑方式相对于粘贴固定具有更好的连接稳定性以及工艺过程的可控性,且在所述模塑基座12与所述电路板11之间不需要预留校准调整的胶水空间,使得摄像模组的厚度得以减小;另一方面,所述模塑基座12包覆所述电子元器件112和所述引线21,不需要像上述实施例中将所述模塑基座12只成型于所述电路板11时,还需要预留后续打线操作以将所述感光元件20连接于所述电路板11的操作空间,从而这个实施例中所述模塑基座12延伸至所述感光元件20的所述非感光区202,使得所述模塑基座12可以向内收缩,从而进一步减小制得所述摄像模组的100的横向的长宽尺寸。
值得一提的是,所述感光元件20通常具有较薄的厚度以及较脆的性质,在为所述感光元件20设计隔离措施的过程中,需确保所述感光元件20不会承受过重的压力而被压碎。同时,在所述感光元件20和所述电路板11之间通常会设有一引线21,其中所述引线在所述感光芯片20和所述电路板11之间弯曲地延伸以导通所述电路板11和所述感光元件20。相应地,在为所述感光元件20设计 隔离措施的过程中,需进一步为所述引线预留空间,以防止在所述感光元件20建立隔离环境中,所述引线21受压变形甚至出现从所述感光元件20或所述电路板11上脱离的现象。相应地,所述成型模具110的结构需作出相应地改进与调整,从而能有效地避免上述所提及的顾虑。
另外,在另外的变形实施方式中,在所述感光元件20组装于所述电路板11上后,所述滤光片50也可以进一步地叠合于所述感光元件20,然后将组装有所述感光元件20和叠合有所述滤光片50的所述电路板11而形成的整体的感光结构组件安装于所述成型模具210,在所述成型模具210合模时,所述光窗成型块214贴合于所述滤光片50的中央区域,以防止所述模塑材料进入所述滤光片50的中央区域,进入所述基座成型导槽215的液体状的所述模塑材料13能够在固化后一体成型于所述电路板11和所述滤光50的边缘区域,并包覆所述电路板11的所述电子元器件112,从而经由所述模塑基座12使所述电路板11,所述感光元件20和所述滤光片50形成一体封装的紧凑结构。
如图20中所示,根据本发明的上述图17到图19的另外改进实施例中,所述成型模具210的所述第一模具211即所述上模还贴附有一层覆盖膜2111,从而在所述成型模具210的所述第一和第二模具211和212合模时,增强所述成型模具与待模塑的所述电路板11和所述感光元件20之间的密封性,并且在模塑工艺结束后方便脱模。
可以理解的是,在另外的变形实施方式中,所述成型模具210的所述第一模具211的成型面也可以通过电镀或其他合适的方法形成一额外层,用来改善成型面的性能,如增加硬度,或选用合适的材料以防止对所述电路板11和所述感光元件20的划伤等。
如图22至图35是根据本发明的另外一个实施例的所述摄像模组100的所述模塑电路板10及其制造设备200,在这个实施例中。所述制造设备200可以同时制作一体结合的模塑电路板拼板1000,所述模塑电路板拼板1000可以作为半成品,然后根据需要所述半成品经过切割以后可以得到多个单体的所述模塑电路板10的成品。
更具体地,如图22和图23所示,所述制造设备包括一成型模具210,一模塑材料供料机构220,一模具固定装置230,一电路板拼板供料机构240,一温控装置250和一控制器260。所述成型模具210包括能够开模和合模的一第一模 具211和一第二模具212,所述模具固定装置230用于将所述第一和第二模具211和212开模或合模,所述模塑材料供料机构220用于向所述成型模具210内供应模塑材料13,所述电路板拼板供料机构240用于自动地将一个或多个电路板拼板1100供应给所述成型模具210,所述控制器260用于控制所述制造设备的操作。
更具体地,所述成型模具210在合模时形成一成型腔213,并且提供多个光窗成型块214和具有多个基座成型导槽215的一个或多个基座拼板成型导槽2150,这些基座成型导槽215相连通并且形成一个整体的导槽。
得一提的是,所述基座拼板成型导槽2150和所述光窗成型块214可以一体地成型于所述第一模具211。也可以是,所述第一模具211进一步地包括可拆卸的成型结构219,所述成型结构219形成有所述基座拼板成型导槽2150和所述光窗成型块214。这样,根据不同的所述模塑电路板拼板的形状和尺寸要求如形成的单体的所述模塑基座的直径和厚度等,可以设计不同形状和尺寸的所述基座接拼板成型导槽2150和所述光窗成型块214。这样,只需要替换不同的所述成型结构219,即可以使所述制造设备适合应用于制作不同规格要求的所述模塑电路板拼板1000。可以理解的是,所述第二模具212相应地也可以包括可拆卸的固定块,以提供不同形状和尺寸的所述凹槽2121,从而方便更换适应不同形状和尺寸的所述电路板拼板1100。
类似地,所述第一模具211和所述第二模具212能够在所述模具固定装置230的驱动作用下产生相对移动,例如其中一个模具固定,而另一个模具可以被所述模具固定装置230驱动而移动;或者两个模具都可被所述模具固定装置230驱动而移动。在本发明的这个实施例中,所述第一模具211实施为固定上模,所述第二模具212实施为可移动下模,所述模具固定装置230用于驱动所述第二模具212竖直方向运动,即所述模具固定装置230能够驱动所述第二模具212向上运动以与所述第一模具211配合而形成闭合状态的所述成型模具210,在需要上料或模塑工艺结束以后,所述模具固定装置230能够驱动所述第二模具212向下运动以离开所述第一模具211。
本领域技术人员可以理解的是,所述模具固定装置230可以是各种合适的能够驱动所述第二模具212移动的装置,例如在一个具体示例中,所述模具固定装置230可以实施为一压机装置,其在动力源如电机、液压或气压等驱动下,推动 所述第二模具212向上运动,并且与所述第一模具211紧密贴合,以形成相对封闭的所述成型腔213。在需要离开合模工作状态时,所述压机装置在相反的驱动作用下,带动所述第二模具212向下运动,从而使所述第一和第二模具211和212相分离。
值得一提的是,本发明的这个实施例中,所述第一和第二模具211和212沿竖直方向布置并且所述第二模具212被驱动向上或向下运动的示例只作为举例,而并不限制本发明,在另外的变形实施方式中,所述第一和第二模具211和212也可能构造成沿水平或其他方向相接合。
所述模塑材料供料机构220包括一个或多个储料器221,一个或多个推料器222,并且具有一个或多个送料通道223,例如可以布置有两个所述送料通道223,以向两个所述电路板拼板1100提供所述模塑材料13。也可以进一步地包括一个或多个运料机构224,其将多个呈料块状的所述模塑材料13可以根据需要输送至对应的所述储料器221。
所述电路板拼板供料机构240包括一个或多个送料导轨241,支撑于所述送料导轨241的一装载器242,以及一卸载器243。其中在所述控制器260的控制作用下,存储在一电路板拼板料盒(未示出)中的一个或多个所述电路板拼板1100被所述装载器242自动沿着各个所述送料导轨241运送至相应的作业工位。在模塑成型工艺完成后,或进一步将所述模塑电路板拼板1000切割下来以后,可以通过所述卸载器243将模塑后的所述模塑电路板拼板1000卸载并在所述导轨241上移动以将所述模塑电路板拼板1000运送至一成品收纳盒(未示出)中。
可以理解的是,所述模具固定装置230,所述模塑材料供料机构220和所述电路板拼板供料机构240以及所述温控装置250都可以所述控制器260的控制作用下连续自动工作,从而可以实现连续自动化模塑工艺。另外,在一些实施例中,所述制造设备200还可以包括一真空设备270,其用于对所述成型腔213进行减压操作,并排除所述成型腔213内的空气,并且可以使所述第一和第二模具211和212更加紧密的压合。
更进一步地,多个所述送料通道223分别与所述基座拼板成型导槽2150相连通。各所述储料器221具有一储料槽2211,所述模塑材料13可以放置于各所述储料槽2211中,通过所述温控装置250将呈固态的所述模塑材料13加热熔化变成液体状的所述模塑材料13。所述储料器221可以是单独的盒体,也可以一 体成型于所述第二模具212,即所述储料槽2211可以一体形成于所述第二模具212的局部位置。
当然,所述制造设备200也可以提供多个所述储料器221和多个对应地用于执行推料操作的所述推料器222,其各自可以独立运作,以对多个所述电路板拼板1100执行模塑操作。例如在图23所示的示例中,所述成型模具210提供四个加工工位,可以同时对四个所述电路板拼板1100进行模塑操作。
可以理解的是,在传统电路板通过胶水粘贴工艺贴附镜座的工艺中,其施胶量难以控制,并且不能保证平整贴附,而且作业耗时长,不能同时大规模作业。而本发明的所述模塑工艺通过拼板作业的方式进行生产时,大大提高了所述模塑电路板10的制作效率。
类似上述实施例地,各个所述送料通道223可以一体地形成在模塑材料供料机构220内,在这个优选实施例中,所述送料通道223实施为形成于所述第一模具211即上模的底侧的导引槽。各个所述推料器222可以为可活动的能够对所述储料槽2211中所述模塑材料13加压并推动的结构,例如可以是一柱塞。
可以理解的是,所述模塑材料13还可以经过称重,或通过控制所述模塑材料13的流速,或控制所述成型模具和所述储料槽内的压力或流量的方式,或其他合适的方式对所述模塑材料13的精确定量。
在所述成型模具210处于合模状态时,经过各个所述推料器222的推动加压作用,液体状的所述模塑材料13被推动通过各所述送料通道223进入所述基座拼板成型导槽2150,从而填充在各个所述光窗成型块214的周围。最后,液体状的所述模塑材料13经过一个固化过程,使位于所述基座拼板成型导槽2150内的液体状的所述模塑材料13固化和硬化从而形成一体模塑于所述电路板拼板1100各个所述电路板11上的所述模塑基座12,这些模塑基座12形成一整体的模塑基座拼板1200。可以理解的是,所述电路板拼板1100的多个所述电路板11排列成一组或多组,每组具有两列所述电路板11,每列具有至少一所述电路板11,其中两列所述电路板11的对应安装所述模塑基座的那一端相邻近地排列,以在两列所述电路板11上形成连体的所述模塑基座拼板1200。例如在图33的示例中,所述模塑电路板拼板1000具有两个所述模塑基座拼板1200,24个所述电路板11被分成两组,每组两列所述电路板11,并且每列具有6个所述电路板11,连体的各个所述模塑基座拼板1200具有连体的12个所述模塑基座12。两 列所述电路板11的感光元件安装端对齐地排列,以方便连体的所述模塑基座拼板的形成。
类似地,在这里的拼板作业工艺中,所述模塑材料13可以是热熔性材料,通过所述温控装置250将呈固态的热熔性材料加热熔化变成液体状的所述模塑材料13。在所述模塑成型的过程中,在所述基座拼板成型导槽2150内的热熔性的所述模塑材料13经过冷却降温过程得以固化成型。
所述模塑材料13也可以是热固性材料,将呈固态的热固性的所述模塑材料13放入各个所述储料槽2211中。通过所述温控装置250将呈固态的热固性材料加热熔化变成液体状的所述模塑材料13。在所述模塑成型的过程中,热固性的所述模塑材料13经过进一步地在所述温控装置250的加热作用下而固化,并且在固化后不再能熔化,从而形成所述模塑基座拼板1200。即在这个实施例中,所述成型模具210和所述模塑材料供料机构220可以都通过一体的所述温控装置250提供加热环境,为避免热固性的所述模塑材料在各个所述储料槽2211中固化,各个所述储料槽2211中所述模塑材料13在受控的加热时间内加热熔化后,及时地呈纯液体状被送入各个所述送料导管2231,或边熔化边以半固态状态被送入各个所述送料通道2231,因为所述成型模具210也在加热环境中,到达所述基座拼板成型导槽2150的所述模塑材料会变成纯液体状态。
可以理解的是,所述成型模具210可以通过所述温控装置250对预先固定的所述电路板拼板1100预加热,从而在所述模塑成型过程中,所述电路板11和液体状的热固性的所述模塑材料13不会有太大的温差。
值得一提的是,所述模塑电路板拼板1000经切割制作得到的单体的各个所述模塑电路板10用于制作动焦摄像模组即自动对焦摄像模组时,所述成型模具210进一步地提供有多个马达引脚槽成型块218,各个所述马达引脚槽成型块218延伸进入所述基座拼板成型导槽2150内,从而在模塑成型过程中,液体状的所述模塑材料13不会填充对应各个所述马达引脚槽成型块218的位置,从而在固化步骤之后,在所述模塑电路板拼板1000的所述模塑基座拼板1200中形成多个所述光窗122以及多个马达引脚槽124,经切割制作得到的单体的各个所述模塑电路板10的所述模塑基座12得以配置有所述马达引脚槽124,从而在制作所述动焦摄像模组100时,所述马达40的引脚41得以通过焊接或导电胶贴附等方式连接于所述模塑电路板10的所述电路板11。
可以理解的是,在另外的变形实施例中,所述电路板拼板1000在对应需要连接所述马达40的所述引脚41的位置凸起地形成连接盘,这样各个所述马达引脚槽成型块218的深度可以减小,从而使所述模塑电路板10的所述模塑基座11在组装所述马达40时,因为从所述电路板11凸起的所述连接盘延伸进入所述马达引脚槽124,可以使所述马达40的不需要长度较长的所述引脚41,即减小所述引脚的长度。
另外,所述第二模具212即所述可移动下模可以具有一电路板拼板定位槽或定位柱2121,用于安装和固定所述电路板拼板1100,而各所述光窗成型块214和所述基座拼板成型导槽2150可以形成在所述第一模具211,即形成在所述上模,当所述第一和第二模具211和212合模时,形成所述成型腔213。并且液体状的所述模塑材料13注入至所述电路板拼板1100的顶侧的所述基座拼板成型导槽2150,从而在所述电路板拼板1100的顶侧形成所述模塑基座拼板1200。
在所述第一和第二模具211和212合模并执行模塑步骤时,各个所述光窗成型块214叠合于所述电路板拼板1100的各个所述基板111的芯片叠合区域111a,并且各个所述光窗成型块214的底表面与所述电路板拼板1100的各个所述基板111的所述芯片叠合区域111a紧密贴合,从而填充至所述基座拼板成型导槽2150的液体状的所述模塑材料13被阻止进入所述电路板拼板1100的各个所述基板111的所述芯片叠合区域111a,而在对应的各个所述芯片叠合区域111a之外的边缘区域111b并且对应所述基座拼板成型导槽2150位置填充有液体状的所述模塑材料13从而形成所述模塑基座拼板1200。
可以理解的是,相对于上述第一个实施例的单体的模塑电路板10的制作工艺,在拼板作业中,用来形成两个所述模塑基座12的相邻的两个所述基座成型导槽215相当于一体交汇在一起,而多个所述光窗成型块214互相间隔地设置,从而使所述模塑材料13最终得以形成一个整体结构的所述模塑基座拼板1200。在这个实施例中,如图33所示,制得的所述模塑基座拼板1200具有多个所述光窗122以及多个所述马达引脚槽124,经切割以后,可以得到如图34中所示的具有一个所述光窗122以及两个所述马达引脚槽124的单体的所述模塑电路板10。并且所述模塑基座拼板1200在对应所述送料通道223的位置形成固化延伸段223a,也就是说,所述模塑基座拼板1200包括一体接合的多个所述模塑基座12以及延伸于一体接合的多个所述模塑基座12的所述固化延伸段223a。
如图28至图32B所示是根据本发明的这个优选实施例的通过拼板作业方式进行所述摄像模组100的所述模朔基座12的制造过程示意图。
如图28至29所示,在模塑成型过程前,在这个示意的示例中,所述电路板拼板1100被固定于所述第二模具212即所述下模的电路板拼板定位槽2121中,向所述电路板拼板1100提供所述模塑材料13的所述储料槽2211被示意位于中间位置,并通过两个所述送料通道223向两个所述基座拼板成型导槽2150供料。
如图30所示,所述成型模具210处于合模状态,待模塑的所述电路板拼板1100和固态的所述模塑材料13固定就位,固态的所述模塑材料13被所述温控装置250加热,从而将所述模塑材料13熔化为液体状态。或者,也可以是被熔化后的所述模塑材料13呈液体状态或半固态状态通过导管输送进入所述储料槽2211。
如图31所示,熔化的所述模塑材料13在所述推料器222的作用下,沿着两个所述送料通道223进入所述基座拼板成型导槽2150,并到达各个所述光窗成型块214的周围。类似地,所述模塑材料13可以全部熔化为液体状态后再被所述推料器222推送入各个所述送料通道223,也可以是所述模塑材料13在边熔化时就被推送入各个所述送料通道223,并且藉由所述温控装置250对所成型模具210提供加热功能而使固态的所述模塑材料13全部熔化呈液体状态。
如图32A和32B所示,当各个所述基座拼板成型导槽2150内全部填充有液体状的所述模塑材料13时,再经过固化过程使液体状的所述模塑材料13固化成型为一体成型于所述电路板拼板1100的所述模塑基座拼板1200。以所述模塑材料13为热固性材料为例,被加热熔化而呈液体状的所述模塑材料13再经过加热过程,从而固化成型。例如可以升温加热,也可以保温加热预定长的时间。制作得到的所述模塑电路板拼板1000可以取出所述成型模具210,并且继续放在烘烤设备中继续加热硬化预定时间。
另外,参照图40,本发明提供一摄像模组100的一模塑电路板10的制造方法,其包括如下步骤:
固定所述电路板拼板1100的步骤:将所述电路板拼板1100传送并装载于所述成型模具210的所述第二模具212;
填充所述模塑材料13的步骤:在所述成型模具210合模后,使液体状态的模塑材料13填充于所述成型模具210内的所述基座拼板成型导槽2150内,其中 所述成型模具210的各个所述光窗成型块214的位置不能填充所述模塑材料13;
固化液体状的所述模塑材料13的步骤:在所述成型模具210内,所述基座拼板成型导槽2150内的所述模塑材料13从液体状态转变成固体状态,从而在所述电路板拼板1100上形成所述模塑基座拼板1200,从而得到所述模塑电路板拼板1000;以及
制作单体的所述模塑电路板10的步骤:将所述模塑电路板拼板1000切割以得到多个所述模塑电路板10。
相应地,在这个实施例中,在固定所述电路板拼板1100的步骤中,所述成型模具210处于开模状态,所述电路板拼板1100通过所述装载器241传送并最终使所电路板拼板1100固定于所述成型模具210的所述第二模具212的所述电路板拼板定位凹槽2121,使所述电路板拼板1100的所述电子元器件112位于顶侧,待在后续模塑成型步骤中被所述模塑材料13一体包覆。
根据本发明的这个实施例,其进一步地包括步骤:将固体状的所述模塑材料13在所述成型模具210合模前预先上料至所述储料槽2211内,固体状的所述模塑材料13可以固体料块,也可以是固体粉末;在所述温控装置250的加热作用下,将固体状的所述模塑材料13熔化并在各个所述推送器222推动作用下经由各个所述送料通道223输送进入所述基座拼板成型导槽2150。推送操作结束后,呈液体状的所述模塑材料13填满所述基座拼板成型导槽2150。另外,在制作动焦摄像模组的所述模塑电路板拼板1000的工艺中,在对应有所述马达引脚槽成型块218的位置也不能填充所述模塑材料13。相应地,在制作定焦摄像模组的所述模塑电路板拼板1000的工艺中,所述成型模具210内可以没有提供所述马达引脚槽成型块218。
在固化液体状的所述模塑材料13的步骤中:在所述模塑材料13是热固性材料时,通过所述温控装置250的加热作用,使得所述成型模具210的所述成型腔213提供有加热环境,这样液体状的所述模塑材料13热固成型而形成一体成型于所述电路板拼板1100上的所述模塑基座拼板1200,并且模塑基座拼板1200包覆所述电子元器件112;在所述模塑材料13是热熔性材料时,液体状的所述模塑材料13在所述成型模具210内冷却,从而冷却固化形成一体成型于所述电路板拼板1100上的所述模塑基座拼板1200。
在制作单体的所述模塑电路板10的步骤中:可以将所述模塑电路板拼板1000 切割以得到多个独立的所述模塑电路板10,以用于制作单体的摄像模组。也可以将一体连接的两个或多个所述模塑电路板10从所述模塑电路板拼板1000切割分离,以用于制作分体式的阵列摄像模组,即所述阵列摄像模组的各个所述摄像模组各自具有独立的所述模塑电路板10,其中两个或多个所述模塑电路板10分别可以连接至同一电子设备的控制主板,这样两个或多个所述模塑电路板10制作得到的阵列摄像模组可以将多个摄像模组拍摄的图像传送至所述控制主板进行图像信息处理。
如图36至图37B中所示,所述拼板作业的模塑工艺也可以用来制作具有两个或多个所述光窗122的模塑电路板10,其中这样的所述模塑电路板10可以用来制作共用基板的阵列摄像模组。也就是说,以制作双摄模组的所述模塑电路板10为例,所述电路板拼板1100的各个电路板11在模塑成型工艺中,一个所述电路板基板111对应地设置有两个所述光窗成型块214,两个互相间隔的所述光窗成型块214的周围是两个一体连通的基座成型导槽,这样在模塑工艺完成以后,各个所述电路板11形成共用一个所述电路板基板111的具有两个所述光窗122的连体模塑基座,对应安装两个所述感光元件20和两个所述镜头30。并且所述电路板11的所述基板111可以连接至一电子设备的控制主板,这样这个实施例中制作得到的阵列摄像模组可以将多个摄像模组拍摄的图像传送至所述控制主板进行图像信息处理。
如图38至图39所示,在本发明的上述另一实施例的另外的变形实施方式中,所述制造模具200可以通过拼板作业制造能够将所述感光元件20一体封装的具有所述感光元件20的所述模塑电路板10。在这个变形实施方式中,一体成型的所述模塑基座12一体地包覆在所述电路板11和所述感光元件20上。
更具体地,多个所述感光元件20分别预先连接于所述电路板拼板1100的对应的所述电路板11,各个所述感光元件20通过一个或多个引线21连接于所述电路板11。并且各个所述感光元件20在顶表面具有一感光区域201和位于所述感光区域201周围的一非感光区域202。一体成型的各个所述模塑基座12将会一体地包覆在对应的所述电路板11的外边缘区域和所述感光元件20的所述非感光区域202的至少部分。
在所述成型模具210开模时,将连接有多个所述感光元件20的所述电路板拼板1100安装于所述第二模具212。如图39所示,在所述成型模具210合模时, 连接有所述感光元件20的所述电路板拼板1100就位于所述成型模具210的所述成型腔213内。各个所述光窗成型块214贴合于对应于各个所述感光元件20的所述感光区域201,所述引线21和所述电路板11的所述电子元器件112位于所述基座拼板成型导槽2150内,并且所述成型模具210的所述成型腔213内也可以设置有多个所述马达引脚槽成型块218,以用于在模塑工艺完成后形成容纳将所述马达40与所述电路板11电性连接的马达引脚41的马达引脚槽。这样当液体状的所述模塑材料13通过各个所述送料通道223进入所述成型模具210内时,液体状的所述模塑材料13只能到达所述光窗成型块214和所述马达引脚槽成型块218的周围,即位于所述基座拼板成型导槽215内,即液体状的所述模塑材料13被阻止进入各个所述感光元件20的所述感光区域201。另外,在另外的变形实施方式中,在各个所述感光元件20组装于所述电路板拼板1100上后,多个所述滤光片50也可以进一步地分别叠合于对应的所述感光元件20,然后在模塑工艺完成以后可以通过一体成型的所述模塑基座拼板1200将这些感光元件20和滤光片50一体封装于所述电路板拼板1100上,然后经切割得到单体的具有一体封装的所述感光元件20和所述滤光片50的所述模塑电路板10。
下面,将描述本发明的所述成型模具的变形方案,为了让本领域的技术人员更加充分地领略改进的所述成型模具的技术特征,重新对所述成型模具和所述模塑电路板的结构进行命名与标号,本领域的技术人员应该理解,新的命名体系只是为了更好地阐述所述成型模具的技术特征,而对本发明的权利范围不添加额外的限制。
具体地说,如图41至图48所示的是根据本发明的另一成型模具8100以及通过所述成型模具8100制备而成的一模塑电路板820。如图41和如图45所示,所述模塑电路板820包括一成像组件821和一模塑基座823,其中所述模塑基座823通过所述成型模具8100制备而成,并一体成型于所述成像组件821,从而所述模塑基座823能够有效地替代传统的摄像模组的镜座或支架,并且不需要类似传统封装工艺中需要将镜座或者支架通过胶水组装于线路板8212。
所述成像组件821进一步地包括一感光元件8211和一线路板8212,其中所述感光元件8211可导通地耦合于所述线路板8212。所述模塑基座823包括一环形模塑主体8231和一光窗8232,其中当所述模塑基座823一体成型于所述成像组件821,所述光窗8232对应于所述成像组件821的所述感光元件 8211的感光路径,以允许所述感光元件8211通过所述模塑基座823的光窗8232接收来自外界的光线。
进一步地,所述线路板8212包括一芯片贴装区域82121和一外围区域82122,所述外围区域82122与所述芯片贴装区域82121一体成型,并且所述芯片贴装区域82121位于所述线路板8212的中部,并被所述外围区域82122所包裹,其中所述感光元件8211对应地贴装于所述线路板8212的所述芯片贴装区域82121。所述线路板8212还包括一组线路板连接件82123,所述线路板连接件82123被设置位于所述芯片贴装区域82121和所述外围区域82122之间,并被用以与所述感光元件8211相导通。
相应地,所述感光元件8211包括一感光区域82111和一非感光区域82112,所述感光区域82111位于所述感光区域82111与所述非感光区域82112一体形成于所述感光元件8211的顶面,并且所述感光区域82111位于所述感光元件8211的中部,并被所述非感光区域82112所包围。所述感光元件8211还包括一组芯片连接件82113,所述芯片连接件82113位于所述感光区域82111,并被用以与所述线路板8212的所述线路板连接件82123相连接,以导通所述线路板8212和所述感光元件8211。
进一步地,所述成像组件821还包括一组引线8214,每一所述引线8214在所述线路板8212和所述感光元件8211之间弯曲地延伸,以导通所述感光元件8211和所述线路板8212。具体地说,每一所述引线8214具有一线路板连接端82141和一芯片连接端82142,其中所述线路板连接端82141被设置连接于所述线路板8212的线路板连接件82123,所述芯片连接端82142被设置连接于所述芯片的芯片连接件82113,通过这样的方式以导通所述线路板8212和所述感光元件8211。值得一提的是,每一所述引线8214在所述线路板8212和所述感光元件8211之间延伸并向上突起,在通过本发明提供的成型模具8100制备所述模塑电路板820时,需为所述引线8214提供一定的布线空间83021,以便在所述模塑基座823模塑成型的过程中,避免所述引线8214被挤压,甚至从所述线路板8212或所述感光元件8211上脱落。
另外,所述成像组件821还包括一系列电子元器件8215,所述电子元器件8215通过诸如SMT等工艺被组装于所述线路板8212,并在所述模塑基座823一体成型后,被所述模塑基座823所包覆,其中所述电子元器件8214包括电容, 电阻,电感等。
本领域的技术人员应当理解,所述线路板8212和所述感光元件8211还可以不通过所述引线8214的方式进行导通,例如,通过芯片倒装方式将所述感光元件8211设置于所述线路板8212的底侧,并且所述感光元件8211的芯片连接件82113直接于所述线路板8212的芯片连接件82113通过导电介质相压合,通过这样的方式,以导通所述线路板8212和感光元件8211。在本发明的该优选实施例中,所述感光元件8211和所述线路板8212通过引线8214连接的方式相互导通仅为举例,以用于更好地阐述本发明提供的成型模具8100在制备所述模塑电路板820过程中所具备的优势。也就是说,在本发明中,所述模塑电路板820仅作为工件来阐述所述成型模具8100的在模塑成型工艺过程中所具备的技术特征,并不影响本发明的权利范围。
具体地说,如图42至如图44所示,所述成型模具8100进一步地包括一上模具8101和一下模具8102,其中当所述上模具8101和所述下模具8102相密合时,在所述上模具8101和下模具8102之间形成一成型空间8103,将所述成像组件821安装于所述成型腔内,进而在用于模塑成型所述模塑基座823的成型材料填充至所述成型空间8103并固化成型后,在所述电路板上一体成型所述模塑基座823,所述模塑基座823包覆所述线路板8212和所述感光元件8211的至少一部分。
更具体地说,所述成型模具8100进一步包括一隔离块830,在所述上模具8101和下模具8102合模时,所述隔离块830在所述成型空间8103内延伸,其中当所述模塑电路板820的成像组件821被安装于所述成型空间8103时,所述隔离块830对应地设置于所述成像组件821的感光元件8211的上部以密封所述感光元件8211,从而当所述成型空间8103被填充成型材料时,所述成型材料无法流入隔离块830和所述感光元件8211,以在所述隔离块830的外侧形成所述模塑基座823的所述环形模塑基座823,同时在所述隔离块830相对应的位置形成所述模塑基座823的所述光窗8232。
所述隔离块830被设置于所述上模具8101,所述成像组件821被安装于所述下模具8102,其中在所述上模具8101与所述下模具8102相互靠近以形成所述成型空间8103的过程中,设置于上模具8101的所述隔离块830逐渐接近位于下模具8102中的所述成像组件821的感光元件8211,并最终被叠合于所述 感光元件8211,从而在所述模塑基座823模塑的工艺过程中,所述隔离块830有效地阻止成型材料进入所述感光元件8211。值得一提的是,所述隔离块830同样可被设置于所述成型模具8100的下模具8102,相应地,将所述成像组件821倒置地安装于所述上模具8101,以在所述上模具8101和下模具8102处于合模状态时,设置于所述下模具8102的所述隔离块830被对应地设置于所述感光元件8211的上部,以通过所述隔离块830密封所述感光元件8211。也就是说,在本发明的所提供的所述成型模具8100中,所述隔离块830的位置不受限制,例如在本发明的该优选实施例中,所述隔离块830被设置于所述成型模具8100的上模具8101,相应地,在所述下模具8102中设置一安装槽81021,所述安装槽81021被用以收容所述模塑电路板820的成像组件821。
更具体地,在所述上模具8101和下模具8102合模并执行模塑工艺时,所述隔离块830与所述感光元件8211相叠合,并至少遮蔽所述感光元件8211的感光区域82111,通过这样的方式,成型材料被阻止进入所述感光元件8211的至少感光区域82111,从而在所述感光元件8211的感光区域82111的外部环境中成型所述模塑基座823,并在所述隔离块830相对应的位置形成所述模塑基座823的所述光窗8232。本领域的技术人员可以理解,在这种情况下,所述隔离块830被设置于所述感光元件8211的所述芯片连接件82113的内侧,并在模塑工艺的过程中,所述隔离块830紧密地贴合于所述感光元件8211的芯片连接件82113内侧的区域,以通过所述隔离块830至少密封所述感光元件8211的感光区域82111,并且在所述模塑基座823一体成型后,所述模塑基座823包覆所述线路板8212和所述感光元件8211以形成具有一体结构的所述模塑电路板820。
如图43所示,所述隔离块830进一步地包括一隔离块主体8301和一侧倾部8302,所述侧倾部8302与所述隔离块主体8301一体成型,并且所述侧倾部8302形成在所述隔离块主体8301的侧部,从而当所述隔离块830被附着于所述感光元件8211的芯片连接件82113的内侧时,所述隔离块主体8301叠合于所述感光元件8211的感光区域82111,所述侧倾部8302在导通所述感光元件8211和所述线路板8212的所述引线8214上方延伸,以防止所述隔离块830与所述引线8214发生触碰。本领域的技术人员应容易理解,所述引线8214在所述感光元件8211的芯片连接件82113和所述线路板8212的线路板连接件 82123之间延伸并向上突起,从而在将所述隔离块830重叠地设置于所述感光元件8211时,必须为所述引线8214提供的充分行线空间,以避免所述隔离块830挤压所述引线8214而导致所述引线8214变形甚至从感光元件8211上脱落。换句话说,当所述隔离块主体8301重叠地设置于所述感光元件8211时,所述侧倾部8302在所述引线8214的上部延伸,从而为所述引线8214提供一布线空间83021,其中所述引线8214在所述布线空间83021内从所述感光元件8211向外自由延伸,以通过所述侧倾部8302有效地避免所述隔离块830与所述引线8214发生触碰。
值得一提的是,在所述模塑基座823模塑成型的过程中,成型材料在所述成型空间8103内流动并填充所述布线空间83021,从而当所述成型材料固化成型后,所述模塑基座823能够更好地贴合所述引线8214。换言之,在通过所述隔离块830界定形成所述布线空间83021的设计过程,不仅仅要为所述引线8214提供充分的空间,以允许所述引线8214能在所述布线空间83021内自由穿梭并凸起,而且还要进一步地调整所述布线空间83021的形状,使得所述布线空间83021的形状更加贴近于所述引线8214的弯曲的形状,从而在后续的模塑工艺中,所述引线8214能够被所述模塑基座823更吻合地包裹以形成更为稳定的一体结构,关于这部分内容,在后续的描述中还会有所涉及。
进一步地,所述隔离块830还包括一延伸部8303,所述延伸部8303与所述隔离块主体8301一体成型,并且所述延伸部8303形成在所述隔离块主体8301的底侧,从而当所述隔离块830被设置位于所述感光元件8211的上部时,所述隔离块830的延伸部8303与所述感光元件8211相密合,以通过所述延伸部8303密封所述感光元件8211的至少感光区域82111。本技术领域的人应当理解,所述延伸部8303从所述隔离块主体8301的底侧向下延伸,通过这样的结构设计,为所述隔离块830赋予了诸多优势。
具体地说,相较没有所述延伸部8303,所述隔离块830的侧倾部8302与所述隔离块主体8301之间的在隔离块830底部的过渡角较大,从而在后续的模塑工艺过程中,成型材料容易通过所述侧倾部8302和所述隔离块主体8301在底部的过渡区域渗入所述感光元件8211,以在所述感光元件8211的周围出现“飞边”等现象。而当所述隔离块830设有所述延伸部8303时,所述延伸部8303一体从所述隔离块主体8301的底部向下延伸并在模塑过程中附着于所述 感光元件8211,通过这样的方式,有效地减少所述隔离块830在底部的过渡角,从而所述隔离块830通过所述延伸部8303更为紧密地贴合于所述感光元件8211,以在所述工艺的过程中更为有效地密封所述感光元件8211的感光区域82111,从而有效地防止成型材料进入所述感光元件8211而出现“飞边”等工艺误差。
其次,所述延伸部8303一体地从所述隔离块主体8301向下延伸,并具有一定的高度,从而当所述隔离块830叠合于所述感光元件8211时,所述延伸部8303能有效地抬高所述隔离块主体8301和所述侧倾部8302的相对位置高度,以有效地扩充所述布线空间83021,从而更便于所述引线8214在所述布线空间83021内自由蜿蜒。换句话说,当所述隔离块主体8301设有所述延伸部8303时,所述布线空间83021形成在所述延伸部8303和所述侧倾部8302的外侧,相较仅通过所述侧倾部8302界定所述布线空间83021的方式,在这种情况下,所述布线空间83021的区域被大幅增加,尤其是在高度方向上的空间,从而能更为有效地避免所述隔离块830与所述引线8214之间发生不必要的接触。举例来说,当所述隔离块830附着于所述感光元件8211,并且所述隔离块830的底部接近于所述感光元件8211的芯片连接件82113时,在这种情况下,所述引线8214在所述感光元件8211的所述芯片连接件82113处的凸起部分极易与所述隔离块830发生触碰,因此,在没有设有所述延伸部8303的情况下,所述隔离块830的侧倾部8302的倾斜程度必须大幅减小,才能勉强避免所述隔离块830与所述引线8214之间发生不必要的触碰。然而,过小的倾斜度所界定的布线空间83021,不利于后续的模塑工艺。
换言之,通过所述隔离块830的所述延伸部8303能在所述隔离块830的侧倾部8302的倾斜程度不做大幅改动的情况下,就能轻易地避免所述隔离块830与所述引线8214之间发生不必要的挤压。本技术领域的人应理解,通过所述隔离块830的所述延伸部8303和所述侧倾部8302相互配合共同界定所述布线空间83021的方式,所述布线空间83021的形状和大小都能做出更为便利的调整,从而一方面能更为有效地避免所述引线8214被所述隔离块830所挤压,另一方面,适当调整所述延伸部8303和所述侧倾部8302的相对位置关系,以使得所述布线空间83021的形状更为贴合所述引线8214的弯曲情况,从而使得后续形成的所述模塑基座823能够更为贴合所述引线8214的线弧。
在本发明的该优选实施例中,所述延伸部8303从所述隔离块主体8301的底侧沿着竖直方向向下延伸,从而当所述隔离块830被设置叠合于所述感光元件8211时,所述延伸部8303近乎垂直地与所述感光元件8211相结合,通过这样的方式,能有效地减少所述隔离块830在底部过渡区域的过度角,从而更为紧密地密封所述感光元件8211,以利于防止在后续的模塑工艺中出现飞边等工艺误差。
如图46A所示是本发明的该优选实施例的一个变形实施,其中所述延伸部8303从所述隔离块主体8301的底侧沿着向下且向内方向延伸,其中所述延伸部8303向内且向下延伸的角度可自由调整,以便于所述延伸部8303与所述倾斜相配合以界定出形状与所述引线8214的线弧更为接近的布线空间83021,从而使得后续形成的模塑基座823能更为紧密且贴合地包覆所述引线8214。值得一提的是,所述隔离块830的所述侧倾部8302的倾斜程度也可自由调整,以协同所述延伸部8303调整所述布线空间83021的形状和大小,以使得所述布线空间83021更加适配于所述引线8214的线弧。
如图46B所示是本发明的该优选实施例的另一变形实施例,其中所述延伸部8303从所述隔离块主体8301的底侧沿着向下且向外方向延伸,其中所述延伸部8303向外且向下延伸的角度可自由调整,从而当所述隔离块830被设置叠合于所述感光元件8211时,所述延伸部8303能进一步地减少所述隔离块830在底部过渡区域的过度角,从而更为紧密地密封所述感光元件8211,以利于防止在后续的模塑工艺中出现飞边等工艺误差。值得一提的是,此种结构特别适用于在后续中描绘中会提及的当所述成型模具8100进一步还包括一缓冲膜的情况,原因在于:从所述隔离块主体的底侧向下且向外延伸的所述延伸部8303对所述缓冲膜8104具有更大的压强,以使得所述缓冲膜8104更紧密地贴合于所述感光元件8211,从而即使所述缓冲膜8104具有较厚的厚度的情况下,也能有效地避免在模塑工艺过程中缓冲膜弯曲后的曲率半径过大而导致底部与芯片表面有较大的缝隙导致出现飞边等不良工艺。进一步地,在本发明的该优选实施例中,所述隔离块830还具有一避让空间8300,所述避让空间8300凹陷地形成在所述隔离块830的底部,从而当所述隔离块830附着于所述感光元件8211时,所述避让空间8300被设置在所述感光元件8211和所述隔离块830之间,以避免所述隔离块830与所述感光元件8211的感光区域82111直接接触,从而有效地 保护所述感光元件8211的感光区域82111不被压伤。优选地,所述避让空间8300被设置具有略大于所述感光元件8211的感光区域82111的空间范围,从而当所述隔离块830与所述感光元件8211相密合时,所述避让空间8300被对应地设置于所述感光元件8211的感光区域82111的上部,以使得所述隔离块830的底部与所述感光元件8211的感光区域82111不发生任何直接的接触,从而有效地减少了在合模的过程中,所述感光芯片的感光区域82111被压碎的事故以及感光区域像素受损的事故。
本技术领域的人应当理解,所述避让空间8300凹陷地形成在所述隔离块830的底部,大幅度减少了所述感光元件8211和所述隔离块830的密合区域,从而有效地降低了所述感光元件8211和所述隔离块830之间的配合难度系数。更具体地说,当所述隔离块830底部没有设有所述避让空间8300时,即所述隔离块830的底部具有完整的一成型面,在这种情况下,只有同时充分保证所述感光元件8211的平整度和所述隔离块830的底部成型面的平整度,才能确保所述感光元件8211和所述隔离块830之间能够精密地贴合。当在所述隔离块830的成型面设有所述避让空间8300时,所述隔离块830的成型面的至少一部分被凹陷,所述隔离块830与所述感光元件8211的接触区域不仅仅被设置位于所述感光元件8211的非感光区域82112,而且该接触区域的面积相较没有设有所述避让空间8300时大幅减少,从而降低了所述感光元件8211和所述隔离块830之间的配合难度,有利于增强所述感光元件8211和所述隔离块830之间的密合程度。在本发明的该优选实施例中,所述避让空间8300被设置形成在所述隔离块830的所述延伸部8303,以配合所述延伸部8303更好地密封所述感光元件8211,从而有利于获得更好的模塑效果。
如图43所示,所述成型模具8100进一步包括一缓冲膜8104,所述缓冲膜8104被设置于所述隔离块830与所述感光元件8211之间,以通过所述缓冲膜8104增强所述隔离块830与所述感光元件8211之间的密封性,从而在后续的模塑工艺中,所述缓冲膜8104能进一步地阻止成型材料进入所述感光元件8211,以提高模塑工艺的成型品质。值得一提的是,在本发明的该优选实施例中,所述缓冲膜8104被贴附于所述隔离块830的底部,以通过所述缓冲膜8104在所述感光元件8211和所述隔离块830之间形成一缓冲层,其中当所述隔离块830叠合于所述感光元件8211时,施加于所述感光元件8211上的负载被所述 缓冲膜8104有效地吸收,从而有效地避免了芯片的损伤。本领域的技术人员应理解,在模塑工艺结束之后,所述成型模具8100的所述上模具8101和所述下模具8102之间相互脱离,以将所述模塑电路板820从所述成型模具8100中脱离,而预先设置的缓冲膜8104此时就能发挥另一层功效:便于模塑电路板820从成型模具8100中脱离。
更具体地说,在本发明的该优选实施例中,所述缓冲膜8104被设置在所述上模具的成型面,以包覆整个所述延伸部8303和所述侧倾部8302,从而当所述隔离块830被设置于所述感光元件8211的上部时,所述缓冲膜8104紧密地贴合于所述感光元件8211,以增强所述隔离块830的密封效果。所述缓冲膜8104具有一定的弹性和柔韧性,当所述缓冲膜8104与所述感光元件8211相密合时,所述隔离块830的延伸部8303挤压着所述缓冲膜8104,并使之被微微挤压变形,从而迫使所述缓冲膜8104更紧密地贴合于所述感光元件8211,以进一步地提高所述感光元件8211的密封效果。更进一步地说,当所述隔离块830的底部设有所述避让空间8300时,由于所述感光元件8211与所述隔离块830底部的接触面积被相应地减少,作用于所述缓冲膜8104上的压强被相应地增高,从而进一步地迫使所述缓冲膜8104向下移动,以进一步缩小所述感光元件8211与所述缓冲膜8104之间的密合间隙,从而进一步地提高所述感光元件8211与所述隔离块830之间的密合效果。值得一体的是,通过改变所述延伸部8303的延伸方向,可相应地改变所述延伸部8303作用于所述缓冲膜8104的力学效果,从而即使所述缓冲膜8104的厚度较大,也能通过所述延伸部8303很好的解决所述感光元件8211与所述缓冲膜8104在所述隔离块830底部的过渡区域间隙过大的问题,从而有效地防止在模塑工艺中出现飞边等工艺误差。
为了确保在模塑工艺的过程中,所述缓冲膜8104始终牢牢地贴附于所述隔离块830的底部,而不发生错位或者偏移等工艺故障。本领域的技术人员应当理解,此处的错位表示的是,在将所述隔离块830对应地贴合于所述感光元件8211时,所述缓冲膜8104从所述隔离块830的底部脱开,以使得所述感光元件8211直接与所述隔离块830发生接触,在这样情况下,所述感光元件8211容易被所述隔离块830所压碎或划伤。此处的偏移指的是,在进行模塑工艺的过程中,所述缓冲膜8104由于没有牢牢地固定,其能在所述隔离块830与所述感光元件8211之间发生移动,以与所述隔离块830和所述感光元件8211之 间发生摩擦而产生碎屑或者将感光元件8211的非感光区域82112上的污尘卷入所述感光元件8211的感光区域82111。
相应地,如图47所示,在本发明的该优选实施例中,所述隔离块830还具有一气体通道8105,所述气体通道8105形成在所述隔离块830的内部,并导通所述隔离块830与所述成型模具8100的外界环境,从而通过所述气体通道8105能有效地在所述隔离块830的底部与缓冲膜8104之间形成一负压空间,以迫使所述缓冲膜8104在所述模塑工艺过程中始终牢牢地贴附于所述隔离块830的底部,从而能够有效地消除错位和偏移等工艺误差。更具体地说,所述气体通道8105具有至少一气体入口81051和一气体出口81052,其中所述气体入口81051被设置形成在所述隔离块830的底部,从而通过所述气体出口81052能有效将所述残留在所述缓冲膜8104和所述隔离块830底部之间的空气吸除,从而在气压差的作用下,所述缓冲膜8104被牢牢地吸附在所述隔离块830的底部。值得一提的是,所述出气口81051的形状不受限制,可为圆形,三角形,多孔密集状等等,也就是说只需所述气体入口81051能够将位于所述缓冲膜8104与所述上模具8101之间的残余气体导出即可。
如图48所示是本发明的另一等效实施例,其中所述隔离块830进一步地包括一刚性段831和一柔性段832,所述柔性段耦合于所述刚性段831并沿着所述刚性段831对齐地向下延伸,其中当所述隔离块830对应地贴合于所述感光元件8211时,所述柔性段832与所述感光元件8211相密合。所述柔性段具有柔软性,能有效防止所述芯片被压碎或者被划伤,同时由于所述柔性段的柔软性,其在与所述感光元件8211密合的过程中进一步加强所述感光元件8211和所述柔性段之间的密封效果。优选地,所述柔性段可替换地耦合于所述刚性段831,从而当所述柔性段出现故障或者失去工作效果时,可选用一新的所述柔性段替代原先的所述柔性段,通过这样的方式,可降低所述成型模具8100的成本。
值得一提的是,所述柔性段由柔性材料制成,并且所述柔性材料与模塑成型材料之间不会相互固结,以使得在模塑工艺之后,所述柔性段能重复使用以进一步降低成本,例如在本发明的该优选实施例中,所述柔性材料为有机聚合物,所述刚性材料为金属,所述柔性段可替换的地耦合于所述金属段,以形成所述成型模具8100的所述隔离块830。值得点出的是,所述成型模具8100特别适用于当所述模塑基座823一体封装所述感光元件8211和所述线路板8212的至少一部 分时的情况,当然所述成型模具8100也可用于当所述模塑基座823一体封装所述线路板8212的至少一部分的情况。
可以理解的是,在另外的变形实施例中,所述隔离块830可以都是柔性材料制成,从而能够与所述感光元件8211相密合,能有效防止所述感光元件8211被压碎或者被划伤。并且值得一提的是,在所述隔离块830采用柔性段832或整体都是柔性材料时,仍然可以采用缓冲膜,并且缓冲膜厚度可以减小。
本领域的技术人员应理解,上述描述及附图中所示的本发明的实施例只作为举例而并不限制本发明。本发明的目的已经完整并有效地实现。本发明的功能及结构原理已在实施例中展示和说明,在没有背离所述原理下,本发明的实施方式可以有任何变形或修改。
