Description

感光组件和摄像模组及其制造方法 技术领域
本发明涉及摄像模组领域,更进一步,涉及一感光组件和摄像模组及其制造方法。
背景技术
传统的摄像模组通常通过COB(Chip On Board)工艺进行封装,COB封装作为一种相对成熟的封装技术,有其优势,同时出现了诸多不利因素。
传统的摄像模组通常包括一线路板、一感光芯片、一滤光片、一底座、一驱动器、一镜头和至少一阻容器件。这些部件以COB方式封装后,所述感光芯片被安装于所述线路板,所述底座被安装于所述线路板,所述滤光片被安装于所述底座,且位于所述感光芯片的感光路径,所述驱动器被安装于所述底座,所述镜头被安装于所述驱动器,以便于位于所述感光芯片的感光路径,且可以通过所述驱动器调节所述摄像模组的焦距。
首先,在现有这种方式中,所述感光芯片被贴附于所述线路板上表面,在这个过程中,所述芯片通常通过胶水粘接的方式贴附于所述线路板,而对于摄像模组,光轴的一致性是一个及其重要的方面,因此在这里对所述感光芯片和所述线路板各自的平整性要求比较高,以便于后续所述镜头主光轴和所述感光芯片的中心光轴的一致。
其次,所述底座以粘接的方式被固定于所述线路板,而所述滤光片、所述驱动器和所述镜头等部件都以所述底座为基础,因此对所述底座自身的平整性以及被安装的平整性都要求较高。
第三,所述感光芯片通过金线电连接于所述线路板,且所述线路板上设有凸出的所述阻容器件,因此在安装所述底座时,需要预留金线和所述阻容器件的空间,使得金线和所述阻容器件在各个方向都不会被碰触,这造成不必要的空间占用。且另一个方面,所述阻容器件上容易沾染灰尘杂物,这些灰尘杂物会影响模组成像,形成乌黑点。
第四,也是相对重要的一方面,适应各种智能设备的发展,比如智能手机,对摄像模组的轻薄化要求越来越高,发展至今,在摄像模组极度微型化的情况下,几乎每一个微小空间对摄像模组都极其重要,而在这种组装方式中,所述感光芯片和所述线路板以及所述阻容器件各自独立占用的空间,使得摄像模组的尺寸不易减小。在这种贴附型的结构中,由于所述感光芯片具有一定的厚度,因此在安装其他部件时,必须需要安装所述底座,为所述感光芯片提供凸出于所述线路板的空间位置。
第五,摄像模组的高度需要符合光学成像的要求,在这种组装方式中,所述芯片贴附在所述线路板上,且所述底座上搭载所述滤光片,因此摄像模组的后焦距较大,摄像模组的整体高度较大。
随着智能电子设备的不断发展,对摄像模组的要求越来越高。智能电子设备,比如智能手机越来越多功能化、轻薄化,相应地,摄像模组也要求向更加优异的成像质量且小型化发展。
以智能手机为例,众所周知,现有的智能手机厚度已经减小到几个毫米,比如6、7毫米,被安装的摄像模组自然要求小于这样的尺寸,很明显,摄像模组已经在一个微型化的尺寸结构。可以想见,在这样微型化的尺寸结构上,对摄像模组进行进一步地缩小变得极其困难。
随着近些年摄像模组的高速发展,模组的各种性能已经进入极佳的水平,且要达到相应的成像质量,各种组成部件以及相对结构基本确定。参照图1,通过COB方式封装的摄像模组,所述摄像模组通常包括一线路板101P、一感光芯片102P、一镜座103P、一镜头104P和一马达105P。所述感光芯片102P被贴装于所述线路板101P,所述镜座103P被安装于所述线路板101P,所述镜头104P被安装于所述马达105P,且使得所述镜头104P位于所述感光芯片102P的感光路径,一滤光片108P被安装于所述镜座103P,位于所述感光芯片102P的感光路径。值得一提的是,所述线路板101P上通常需要贴装一些阻容器件106P和一金线107P,比如贴装电阻、电容来配合所述线路板101P的工作,所述阻容器件106P和所述金线107P通常凸出于所述线路板101P,现有的这种结构存在诸多问题。
首先,所述镜座103P通过胶水粘接在所述线路板101P上,由于所述镜座103P本身的不平整和贴附的组装倾斜,最终容易造成模组的倾斜,光轴的不一致。
其次,所述阻容器件106P、所述金线107P与所述感光芯片102P在同一连通的空间内,所述阻容器件106P和所述金线107P上残留的灰尘、杂质容易转移到所述感光芯片102P上,从而影响所述摄像模组的成像质量,使得所述摄像模组的成像中出现黑点、污点等不良影响。
第三,所述镜座103P通过胶水粘接于所述线路板101P,结构强度较差,因此要求所述线路板101P的厚度较大,使得所述摄像模组的厚度不易降低。
第四,现有的COB封装的摄像模组结构已经达到较高的优化程度,各部件,如所述镜座103P、所述线路板101P、所述感光芯片102P、所述镜头104P和所述马达105P的相对位置以及结构关系已相对确定,在这个基础上,摄像模组的尺寸很难进一步减小。
第五,所述感光芯片102P贴附在所述线路板101P上,叠层的结构关系使得所述摄像模组的高度较大。
第六,也是比较重要的一点,所述感光芯片102P通过胶水粘接的方式贴附于所述线路板101P,所述感光芯片102P上方被密封于所述镜头104P相对的空间内,下方被所述线路板101P阻挡,因此所述感光芯片102P的整体散热效果较差,只能通过所述线路板101P的传导作用来散热,而通常来说线路板的散热效果都较差。进一步地,当所述感光芯片102P发热时,容易影响所述摄像模组的工作性能,比如影响成像质量。
近年来,电子设备越来越朝向轻薄化和高性能方向发展,这对作为电子设备的标准配置之一的摄像模组的尺寸和性能都提出了非常苛刻的要求。本领域的技术人员应当知道,摄像模组的成像品质不仅取决于摄像模组的感光芯片的性能,而且极大地受限于感光芯片的平整度,因此,现有的摄像模组为了保证感光芯片的平整度,通常会选用具有高大厚度和更高强度的线路板,这导致摄像模组的高度尺寸被增加。
另外,现有的摄像模组通过SMT工艺(Surface Mount Technology,表面贴附工艺)将感光芯片贴装在线路板上,在执行SMT工艺时,需要在感光芯片和线路板之间设置胶水或者类似的粘着物,这些位于感光芯片和线路板之间的不同位置的粘着物在固化时变形率存在着差异,从而导致感光芯片出现倾斜等不良现象,并且填充在感光芯片和线路板之间的粘着物也导致摄像模组的高度尺寸被增加。
线路板是一种高分子材料板,由于线路板的厚度尺寸被要求的尽可能薄,当摄像模组被使用时,被直接贴装于线路板的感光芯片在进行光电转化时会产生热量,这些热量持续地作用于线路板会导致线路板出现变形,从而影响感光芯片的平整度。为了解决线路板受热变形而影响感光芯片的平整度的不良现象,有些摄像模组的线路板被重叠地设置一个金属层,以藉由这个金属层使线路板在受热时也不会出现变形,然而,这种方式不仅增加了摄像模组的制造成本,而且进一步增加了摄像模组的高度尺寸。

所述电子元器件10123和所述电连接元件1014被封装于所述封装体1013内,换句话说,所述电连接元件1014和所述电子元器件10123被所述封装体1013包裹,从而不会暴露于外部环境。在现有的方式中,连接金线和阻容器件通常暴露于外部,一方面金线和阻容器件上沾染的灰尘会影响摄像模组的成像质量,另一方面,需要预留金线和阻容器件的安装空间,因此造成摄像模组的空间浪费。
所述窗体线路板1012包括一线路板主体10121,且所述窗体线路板1012具有一窗口10122。所述窗口10122被设置于所述线路板主体10121,从而形成一窗体形线路板。所述感光元件1011被容纳于所述窗口10122内,从而减少所述感光元件1011额外占用的空间。
也就是说,所述感光元件1011被容纳于所述窗体线路板1012的所述窗口10122内,使得所述感光元件1011相对于所述线路板主体10121的位置下沉,使得所述感光元件1011和所述线路板主体10121的相对高度降低。当所述感光元件1011的所述顶表面10111高度不高于所述线路板主体10121的所述顶面101211时,所述线路板主体1011为所述感光元件1011提供充分的空间环境,且所述感光元件1011和所述线路板主体10121的整体高度仅表现为所述线路板主体10121的高度。
所述线路板主体10121具有一顶面101211和一底面101212,所述封装体1013封装于所述线路板主体10121的所述顶面101211以及所述感光元件1011的所述顶表面10111的所述非感光区101112。所述窗体线路板1012的所述窗口10122的尺寸可以根据所述感光元件1011的尺寸进行设置,可以和所述感光元件1011的尺寸相当,使得所述窗口10122适于容纳所述感光元件1011,也可以是大于所述感光元件1011,在便于容纳所述感光元件1011的同时,便于调节所述感光元件1011。在一种实施过程中,在所述感光元件1011和所述窗体线路板1012之间可以预留一间隙10125,便于安装,且通过所述封装体1013填充所述间隙10125,固定所述感光元件1011。参照图3,在一种实施方式中,所述封装体1013进入所述间隙10125,填充所述线路板主体10121和所述感光元件1011之间的空间,并且使得所述封装体1013延伸进入所述间隙10125位置和所述感光元件1011的所述底表面10112以及所述线路板主体10121的所述底面101212高度大体一致。这样,所述封装体1013能够加固所述感光元件1011和所述窗体线路板1012。
参照图6A,在另一实施方式中,所述封装体1013未进入所述间隙10125,且使得所述封装体1013和所述感光元件1011顶表面10111以及所述线路板主体10121的顶面101211的高度大体一致,而在实施的过程中,通过粘接剂粘,如胶水,粘接所述感光元件1011和所述线路板主体10121,阻挡所述封装体1013进入所述间隙10125。参照图6B,在另一种实施方式中,所述封装体1013延伸进入所述间隙10125,并且穿过所述间隙10125包覆所述感光组件1010的底部。本领域的技术人员应当理解的是,所述间隙10125以及所述封装体1013和所述间隙1013的关系可以根据需要设置,所述间隙10125的大小以及所述封装体1013在所述间隙10125中延伸的位置,并不是本发明的限制。
值得一提的是,在另外的实施例中,所述线路板主体10121也可以不与所述感光元件1011之间相间隔而形成所述间隙10125,而可以是直接接触。值得一提的是,当所述封装体1013加固所述窗体线路板1012和所述感光元件1011时,不像现有技术中需要在线路板底部增加补强板,所述封装体即可以起到对所述窗体线路板1012的补强作用。当然,本发明的所述窗体线路板1012的背侧也可以进一步地设置补强板以进一步地加强所述感光组件1010的封装强度。
在制造所述感光组件1010的过程中,先将一线路板基体进行开窗,形成具有所述窗口10122的所述窗体线路板1012,而后将所述感光元件1011设置于所述窗口10122内(也可以通过胶水将所述感光元件1011和所述窗体线路板1012固定),继而将所述感光元件1011和所述线路板主体10121通过所述电连接元件1014进行电连接,比如邦定的方式,进而通过一体封装的方式将所述感光元件1011的非感光区101112、所述电连接元件1014、所述电子元器件10123、所述窗体线路板1012进行一体地封装。
所述线路板主体10121的材料可以是软硬结合板RG(Rigid Flex)、挠性印制电路板FPC(Flex Print Circuit)、刚性印制电路板PCB(Printed Circuit Board)、陶瓷基板等等。
值得一提的是,所述感光元件1011的所述非感光区101112的封装区域可以根据需求设置,也就是说,所述非感光区101112可以被全部封装,也可以被部分地封装,本领域的技术人员应当理解的是,所述封装区域的大小以及形状并不是本发明的限制。
在本发明中,所述封装体1013通过模塑(Molding)工艺方式一体地形成,区别于传统的底座,粘接于线路板。在制造所述感光组件1010时,将所述感光元件1011和所述窗体线路板1012放入模具,而后向模具内施加模塑材料,固化后形成预定形状的所述封装体1013,且通过所述封装体1013将所述感光元件1011和所述窗体线路板1012固定。所述模塑材料可以选择尼龙、LCP(Liquid Crystal Polymer,液晶高分子聚合物)、PP(Polypropylene,聚丙烯)、环氧树脂以及其它热塑或热固性材料。
这种一体封装的方式,减少了传统的胶水粘接底座的过程,且所述封装体1013通过模塑的方式制造,形状更容易控制、表面平整性较好,因此能够为所述滤光片1040、所述驱动器1030以及所述镜头1020提供平整的安装条件,有 助于保证所述摄像模组光轴的一致性。另一方面,减少了传统的胶水粘接空间,有助于降低所述摄像模组的高度。进一步,在本发明的实施例中,将所述感光元件1011设置于所述窗口10122内,而后进行一体封装,因此在形成所述封装体1013时不需要考虑所述感光元件1011的厚度,从而进一步提供了减小所述摄像模组高度的可能空间。
所述封装体1013俯视呈环形结构,举例地但不限于,方形、圆形、三角形,以便于为所述滤光片1040、所述驱动器1030或所述镜头1020提供安装位置,从而当所述驱动器1030或所述镜头1020被安装于所述封装体1013时,形成一封闭的内环境。且借助模具化的一体封装优势,可以保证所述封装体1013表面的平整,从而为所述滤光片1040、所述镜头1020或所述驱动器1030提供平整的安装条件。
根据本发明的这个实施方式,所述窗口10122为一通孔,也就是说,所述窗口10122连通于所述线路板主体10121的两侧,从而为所述感光元件1011提供可以调节的空间。换句话说,所述感光元件1011在所述窗口10122内和所述线路板主体10121的相对位置,可以根据需要设置。
值得一提的是,在本发明中,所述感光元件1011和所述窗体线路板1012通过所述封装体1013一体的封装,从而当所述感光元件1011被设置于窗口10122内时,可以不需要额外的支撑部件来固定所述感光元件1011,使得所述感光元件1011的位置可以相对自由地选取。换句话说,所述封装体1013从上方分别为所述感光元件1011和所述线路板主体10121提供固定作用,从而不需要所述线路板主体10121或其他部件从其他方向,比如下方,为所述感光元件1011提供支撑、固定作用。且通过所述封装体1013的一体封装作用,可以增强所述线路板主体10121和所述感光元件1011的结构强度。
进一步,根据本发明这种实施方式,所述感光元件1011被设置于靠近所述窗口10122下方的位置,所述电连接元件1014一端连接于所述感光元件1011的所述非感光区101112,所述连接的另一端穿过所述窗口10122连接于所述线路板主体10121。
进一步,所述感光元件1011的所述底表面10112和所述线路板主体10121的底面101212高度相对一致,从而使得所述感光组件1010的底部相对平整,不会出现明显的台阶。换句话说,所述感光元件1011的所述底表面10112和所述 线路板主体101212的底面101212大体上齐平。
在这种方式中,所述感光元件1011的底表面10112显露于外部空间中,因此增强了所述感光元件1011的散热功能,而不同于贴附的方式中,所述底表面10112被线路板阻挡,散热性能较差。
举例地,本发明提供两种所述窗体线路板1012的制造方法,在一种方法中,先将基板层开设所述窗口10122,所述窗口10122的大小根据所述感光元件1011确定,而后叠层设置各所述基板层,并且在预定的各基板层之间埋设电路,从而形成一具有所述窗口10122的所述窗体线路板1012。在另一种方法中,将基板层叠地布置,且在各基板层之间按预定路线埋设电路,且埋设路线根据所述感光元件1011的放置位置而定,而后在叠层的基板层上开所述窗口10122,所述窗口10122在埋设的电路之内,根据所述感光元件1011的形状确定,也就是说,不会损伤电路。
如图7所示,是根据本发明的第一个优选实施例的摄像模组的感光组件1010的第一种变形实施方式。不同于上述实施方式的是,在这种实施方式中,所述感光元件1011的所述顶表面10111和所述线路板主体10121的所述顶面101211高度相对一致。也就是说,所述感光元件1011的所述顶表面10111和所述线路板主体10121的所述顶面101211大体上齐平,在所述感光元件1011的下方位置预留空间。在上表面齐平的情况下,将所述感光元件1011和所述窗体线路板1012通过所述电连接元件1014进行电连接。
在制造这种感光元件1011的过程中,可以提供一凸台形的治具,来支撑所述感光元件1011,从而使得所述感光元件1011和所述窗体线路板1012的上表面齐平,而后对所述感光元件1011和所述窗体线路板1012进行一体封装,形成所述封装体1013,从而通过所述封装体1013使得所述感光元件1011和所述窗体线路板1012的相对位置固定。
如图8所示,是根据本发明的第一个优选实施例的摄像模组的感光组件1010的第二种变形实施方式。不同上述实施方式的是,在这个实施方式中,所述感光元件1011包括一阻隔件1015,所述阻隔件1015被设置于所述封装体1013和所述感光元件1011相接的位置,用于防止所述封装体1013对所述感光元件1011内侧区域的影响,比如对所述感光区101111的污染,即,所述阻隔件1015设置于所述感光区10111外侧,以便于在制造的过程中,阻挡流体状态的模塑材料进 入所述感光区101111,并且在封装模具作业的过程中保护所述感光元件1011。
所述阻隔件1015呈环形或框形结构,设置于所述感光元件1011上。也就是说,所述封装体1013的内边缘和所述感光元件1011相接的位置通过所述阻隔件1015阻隔。
所述阻隔件1015可以通过胶体形成,也可以为预定形状的塑料元件。
在制造这个感光组件1010的过程中,在对所述感光元件1011和所述窗体线路板1012进行一体封装之前,需要在所述感光元件1011上设置所述阻隔件1015,比如涂布胶水,进而以所述阻隔件1015为界限,形成所述封装体1013,从而使得所述封装体1013材料不会污染所述感光元件1011位于所述阻隔件1015内侧的区域。
如图9和图10所示,根据本发明的第二个优选实施例的摄像模组。不同于上述优选实施例的是,所述窗口10122A为一凹槽结构,也就是说,所述感光元件1011被容纳于所述凹槽结构内,从而使得所述感光元件1011和所述窗体线路板1012的表面的相对高度减小。更进一步,当所述凹槽结构的深度大于等于所述感光元件1011的厚度时,所述感光元件1011和所述窗体线路板1012的整体厚度表现为所述窗体线路板1012的厚度。
所述窗口10122A对应一窗底10124A,所述感光元件1011被设置于所述窗底10124A。换句话说,所述窗底10124A支撑所述感光元件1011。所述窗口10122A的尺寸可以和所述感光元件1011的尺寸相匹配,从而使得所述感光元件1011和所述线路板主体10121的表面平齐。当然,所述感光元件1011和所述线路板主体10121之间还可以存在间隙,而后通过粘接剂将所述感光元件1011与所述线路板主体10121固定。
在本发明的这个实施例中,所述电连接元件1014电连接于所述感光元件1011和所述线路板主体10121。也就是说,所述电连接元件1014连接位于窗口10122A内的所述感光元件1011和所述窗口10122A外部的所述线路板主体顶面101211。
如图11所示根据本发明的第二个优选实施例的摄像模组的感光组件1010的变形实施方式。不同于上述优选实施例的是,所述电连接元件1014被设置于所述窗体线路板1012的所述窗口10122A内。进一步,所述电连接元件1014一端连接所述感光元件1011的所述非感光区101112,另一端连接于所述窗口10122A 对应的所述窗底10124A的线路板表面。相对于上述实施方式,由于要在所述线路板主体10121的所述窗底的线路板表面10124A设置电连接结构,且在较小的空间内要完成所述电连接元件1014和所述感光元件1011的电连接过程,因此工艺难度要大于上述实施方式。
相对上述第一个优选实施例,从制作工艺方面来比较,第二个实施例的凹槽状的所述窗口10122的加工难度要大于通孔形的所述窗口10122A。由于线路板的厚度较小,而在厚度较小的线路板上设置凹槽,工艺精度要求较高,且如果将所述电连接元件1014设置于凹槽内,相当于在更薄的线路板上设置电路,难度更高,因此整体考虑,通孔形的所述窗口10122A以及所述电连接元件1014连接于外部的方式更适于实施,且提供更多的所述感光元件1011可以调节的空间,且散热性能较好。
如图12和图13所示,是根据本发明的第三个优选实施例的摄像模组。不同于上述优选实施的是,在这种实施方式中,所述感光组件1010包括一滤光片1040B,所述滤光片1040B被附着于所述感光元件1011。也就是说,所述滤光片1040B遮挡所述感光元件1011,从而减少对所述感光元件1011的污染以及模具对所述感光元件1011的损伤。
在这种实施方式中,所述封装体1013上表面可以是一平整的平面结构,而不需要设置为台阶状结构来安装所述滤光片1040B。所述驱动器1030或所述镜头1020被安装于所述封装体1013。
举例地,所述滤光片1040B可以通过粘接的方式连接于所述感光元件1011。在其他实施方式中,所述滤光片1040B还可以通过吸附的方式连接于所述感光元件1011,本领域的技术人员应当理解的是,所述滤光片1040B和所述感光元件1011的具体连接方式,并不是本发明的限制。
在这种方式中,所述滤光片1040B被设置于所述感光元件1011,因此在所述摄像模组中,不需要在所述封装体1013上安装所述滤光片1040B,且在这种方式中,所述滤光片1040B和所述感光元件1011的距离减小,因此缩小了所述摄像模组的后焦距,从而使得所述摄像模组的高度能够进一步减小。
在制造所述感光组件1010的过程中,可以在对所述感光元件1011和所述窗体线路板1012进行一体封装前,将所述滤光片1040B附着于所述感光元件1011上,从而通过所述滤光元件1040B遮挡所述感光元件1011,特别是遮挡所述感 光元件1011的所述感光区-101111,从而在一体封装的过程中,通过所述滤光片1040B遮挡、保护所述感光元件1011,防止所述封装体1013的封装材料污染所述感光元件1011,从而提高成像质量。当然,在本发明其他实施例中,也可以在所述封装体1013形成之后设置所述滤光片1040B,减小摄像模组的后焦距,本领域的技术人员应当理解的是,所述滤光片1040B的设置顺序,并不是本发明的限制。
如图14所示,是根据本发明的第三个优选实施例的摄像模组的感光组件1010的一变形实施方式。不同于上述实施方式的是,在这种实施方式中,所述感光元件1011包括一滤光片1040B,所述滤光片1040B被附着于所述感光元件1011,且所述滤光片1040B的外边缘被所述封装体1013一体封装。也就是说,所述感光元件1011、所述窗体线路板1012和所述滤光片1040B都被所述封装体1013一体封装,从而将所述滤光片1040B固定。在制造这种感光组件1010时,需要在形成所述封装体1013之前,将所述滤光片1040B重叠于所述感光元件1011,可以通过胶水粘接,也可以不进行粘接,而通过一体封装的方式固定所述滤光片1040B。
如图15所示,是根据本发明的第四个优选实施例的摄像模组。不同于上述实施例的是,所述感光组件1010包括一封装体1013C,所述封装体1013C包括一支架部10131C和一镜头部10132C。所述支架部10131C用于安装所述滤光片1040,所述镜头部10132C用于安装所述镜头1020。
进一步,所述镜头部10132C外部沿所述支架部10131C一体地向上延伸,内部形成台阶状结构。所述支架部10131C包括一第一支撑台101311C,所述滤光片1040被安装于所述第一支撑台101311C。所述镜头部10132C包括一第二支撑台101321C,所述镜头1020被安装于所述第二支撑台101321C,也就是说,所述第一支撑台101311C和所述第二支撑台101321C形成两阶台阶结构。
所述镜头部10132C一体地延伸,以便于为所述镜头1020提供稳定的安装环境。根据本发明的这个实施例,所述镜头部10132C的深度可以根据所述镜头1020的高度确定,以便于稳定地安装所述镜头1020,提高摄像模组的精度。
在这种方式中,为所述镜头1020提供一安装环境,形成一定焦摄像模组,且可以借助模具化的一体封装方式,为所述镜头1020提供平整、稳定的安装环境。
进一步,在这种实施方式中,所述镜头部10132C内部平整,适于一安装无螺纹镜头。
如图16所示,是根据本发明的第四个优选实施例的摄像模组的变形实施方式。不同于上述优选实施方式的是,在这种实施方式中,所述镜头部10132C的内部具有一螺纹结构101322C,适于安装一带螺纹的镜头。当然在其他实施例中,所述镜头部10132C内部还可以是其他不同的结构,以便于安装不同类型的镜头。
如图17所示,是根据本发明的第五个优选实施例的摄像模组的剖视示意图。不同于上述优选实施例的是,所述感光组件1010包括一衬底1016,所述衬底1016被设置于所述感光元件1011下方。
进一步,所述衬底1016底部的高度和所述线路板主体10121的所述底面101212的高度大体一致,从而使得所述感光组件1010底部保持平整。换句话说,所述衬底1016填充所述感光元件1011下方的所述窗口10122的剩余空间,从而使得当所述感光元件1011的厚度小于所述线路板主体10121的厚度,且所述感光元件1011被布置于靠近所述线路板主体10121的所述顶面101211的位置时,所述感光组件1010的底部仍旧能够保持平整,不会出现明显的台阶结构。
所述衬底1016可以增强所述感光组件1010的结构强度,以及散热性能。在一实施例中,所述衬底1016可以为金属板或塑料板。而在另一实施例中,所述衬底1016可以为一膜层,附着于所述感光元件1011的所述下表面10112,以便于保护所述感光元件1011,增强所述感光元件1011的散热性能以及结构强度。举例地但不限于,所述膜层为一金属涂层。
所述衬底1016可以通过粘接的方式连接于所述线路板主体10121,或通过粘接的方式连接于所述感光元件1011。
当然,在其他实施例中,所述衬底1016可以被设置于所述线路板主体10121下方,比如当所述感光元件1011的厚度大于所述线路板主体10121的厚度时,可以通过所述衬底1016补齐所述感光元件1011和所述线路板主体10121之间的高度差,从而使得所述感光组件1010底部保持平整。
如图18所示,是根据本发明的第五个优选实施例的摄像模组的感光组件的一变形实施方式。不同于上述实施方式的是,所述窗体线路板1012包括一衬底1016D,所述衬底1016D被容纳于所述窗体线路板1012的所述窗口10122内。所述衬底1016D呈凹槽状结构,所述感光元件1011被容纳于所述衬底1016D。 也就是说,所述衬底1016D为所述感光元件1011通过一安装位置,使得所述感光元件1011和所述线路板主体10121的所述顶面101211平齐,且所述衬底1016D的下表面与所述线路板主体10121的所述底面101212的高度大体一致,使得所述感光组件1010底部平整。
如图19所示,是根据本发明的第六个优选实施例的摄像模组。不同于上述实施例的是,所述窗体线路板1012的所述线路板主体10121具有至少一加固孔101213,所述封装体1013延伸进入所述加固孔101213,从而增强所述线路板主体10121的结构强度。所述加固孔101213的数量及深度可以根据需要布置,设置于所述窗体线路板1012未设置电路的位置。
在这种实施方式中,所述加固孔101213为凹孔,也就是说,所述线路板主体10121两侧没有通过所述加固孔101213连通。
图20是根据本发明的第六个优选实施例的摄像模组的感光组件1010的变形实施方式。不同于上述实施方式的是,所述窗体线路板1012的所述线路板主体10121具有至少一加固孔101213E,所述封装体1013延伸进入所述加固孔101213E,且所述加固孔101213E为穿孔。也就是说,可以通过所述加固孔101213E连通所述线路板主体10121两侧。
进一步,所述封装体1013通过所述加固孔101213E,延伸至所述线路板主体10121和所述感光元件1011的底部,从而在所述感光组件1010底部形成一封装层10133E。所述封装层10133E增强了所述感光组件1010的结构强度。
也就是说,在这种实施方式中,所述封装体1013不仅被设置于所述线路板主体10121和所述感光元件1011的上部,还被一体地设置于所述感光元件1011的下部。当然在其他实施例中,所述封装层10133E可以只设置于所述线路板主体10121下方,而在所述感光元件1011下方不设置。
如图21所示,是根据本发明的第七个优选实施例的摄像模组。不同于上述优选实施例的是,所述感光组件1010包括一背板1017,所述背板1017被设置于所述线路板主体10121底部,以增强所述线路板主体10121的结构强度,使得所述感光组件1010底部平整。在一实施例中,所述背板1017可以为金属板,从而在增强所述感光组件1010的结构强度的同时,增加所述感光组件1010的散热性能。而在另一实施例中,所述背板1017可以为一膜层,附着于所述感光元件1011的所述底表面10112和所述线路板10121的所述底面101212,以便于保护 所述感光元件1011和所述线路板主体10121,增强所述感光元件1011的散热性能以及结构强度。举例地但不限于,所述膜层为一含金属材料的涂层。
如图22所示是根据本发明的第八个优选实施例的摄像模组。不同于上述实施例的是,所述摄像模组包括一支架1050,所述支架1050被安装于所述封装体1013,所述滤光片1040被安装于所述支架1050。
进一步,所述支架1050可以形成一弯折结构,以便于一端适于被安装于所述封装体1013,另一端适于支撑所述滤光片1040。
所述支架1050可以向内、向下延伸,从而减小所述滤光片1040和所述感光元件1011的距离,减小所述摄像模组的后焦距。
在这个实施方式中,通过所述支架1050为所述滤光片1040提供一安装位置,而不是通过所述封装体1013直接提供所述滤光片1040的安装位置,值得一提的是,图中所示的所述支架1050的结构仅作为示意,并不是本发明的限制。由于所述滤光片1040的结构强度较小,因此在安装时需要的安装位置空间较大,而通过结构强度较大的所述支架1050,可以减小对所述一体封装部的安装位置的宽度要求,同时也可以缓冲模组受到外力冲击时对所述滤光片1040产生的应力。
所述支架1050俯视可以为一闭合环形或框形结构,也可以选择性地设置于所述封装体1013或所述滤光片1040的一边或多个边。
如图23所示,是根据本发明的第九个优选实施例的摄像模组。不同于上述实施例的是,所述摄像模组是一阵列摄像模组,所述阵列摄像模组包括两所述感光组件1010、两所述镜头1020、两所述驱动器1030和两所述滤光片1040。
值得一提的是,为了方便揭露本发明,在本发明的这个实施例中,以两个所述镜头1020构成的双摄模组为例来进行说明,而在本发明的其他实施例中,所述镜头1020的数量可以为更多个,比如三个或三个以上,本领域的技术人员应当理解的是,所述镜头1020的数量以及相应组件的数量,如所述驱动器1030、所述支架1050、所述滤光片1040的数量并不是本发明的限制。
更具体地,在本发明的这个实施例中,两所述感光组件1010的所述窗体线路板1012一体地连接,以便于形成阵列的结构。两所述封装体1013可以为一体结构,也就是说,一次形成两方形窗体结构,以便于分别为两所述镜头1020提供光线通路。
本发明中揭露了多个实施例以及不同的实施方式,在描述过程中,为了便于 简洁、清楚地描述,仅在各实施例以及实施方式中,描述了一些区别特征,但是在具体实施过程中,可以根据需要将不同实施例以及实施方式中的不同特征进行组合,从而形成不同的摄像模组或感光组件,本领域的技术人员应当理解的是,所述摄像模组和所述感光组件1010不限于单个实施例或实施方式揭露的内容。

在所述步骤101300中,一体封装所述感光元件1011、所述电连接元件1014和凸出于所述窗体线路板1012的所述电子元器件10123。
所述方法101000还可以包括步骤101400:附着一滤光片1040于所述感光元件1011。所述步骤101400可以在所述步骤101300之前,也可以在所述步骤101300之后。所述附着的方式可以为粘接的方式。

在一种实施方式中,所述步骤101300中,所述感光元件和所述窗体线路板之间相接触,所述封装体一体地连接所述感光元件1011和所述窗体线路板1012。
在另一实施方式中,所述步骤101300中,所述感光元件1011和所述窗体线路板1012之间相间隔,所述封装体1013一体地连接和填充在所述感光元件1011和所述窗体线路板1012之间以加固所述感光元件1011和所述窗体线路板1012。
在另一实施例中,所述步骤101300中,所述感光元件1011和所述窗体线路板1012之间通过一介质间接接触,所述封装体1013一体地连接所述感光元件1011、所述介质和所述窗体线路板1012。比如,通过胶水先将所述感光元件1011的所述非感光区101112的四周至少部分区域进行固化而使得所述感光元件1011和所述窗体线路板1012间接接触。
所述一体封装的方式为模塑成型的方式,比如通过注塑机采用insert molding或compression molding(模压成型)或Transfer molding(传递模塑)工艺加工。
参照图25A至图26B,根据本发明的第十个优选实施例的摄像模组20100被阐释。所述摄像模组20100也可以称为下沉式摄像模组。所述摄像模组20100包括一感光组件2010和一镜头2020。所述感光组件2010也可以称为下沉式感光组件。
进一步,所述感光组件2010包括一一体封装基座2011、一电路板2012和一感光元件2013。所述电路板2012也可以称为下沉电路板。所述感光元件2013下沉于所述电路板2012,所述一体封装基座2011一体封装所述电路板2012和所述感光元件2013。所述一体封装的方式举例地但不限于通过传递模塑的方式一体封装。
值得一提的是,在传统的COB封装结构中,镜座通常通过单独制造而成,比如通过注塑的方式制造,且在单独制造完成后,在进行组装时,通过胶水粘接于线路板,因此在这种组装方式中诸多不利因素,而在本发明中,一方面,通过所述感光元件2013下沉于所述电路板2012的方式,减小所述感光元件2013与所述电路板2012的表面相对高度,从而使得镜头2020可以更加靠近所述电路板2012,减小所述摄像模组的高度。另一方面,在所述感光元件2013下沉于所述电路板2012时,所述一体封装基座2011一体封装所述电路板2012和所述感光元件2013,从而不需要像传统的芯片贴装工艺一样通过线路板为感光芯片提供支撑,也就是说,在本发明中,不管所述感光元件2013是否受到所述电路板2012 的支撑,都能够通过所述一体封装基座2011固定所述感光元件2013和所述电路板2012的相对位置,这一点,在传统的COB封装工艺中是难以实现的。进一步,所述一体封装基座2011通过一体封装的方式成型于所述电路板2012,替代传统的镜座,取得诸多优势:第一,一体封装替代了传统粘接的工艺过程,不需要预留AA调整中的调整间隙,减小摄像模组的高度;第二,一体封装的组装方式可以借助模具制造来提高表面的平整性,从而提高摄像模组的组装精度;第三,一体封装可以增强所述电路板2012的结构强度,从而当所述电路板2012通过开槽或开孔等方式,使得感光元件2013下沉时,仍旧可以满足结构强度需求,而传统的镜座和线路板粘接方式则难以达到这样的要求;第四,所述一体封装基座2011可以一体包覆所述电路板2012上的凸出部件,比如后续提出的所述电子元器件20123,从而可以充分利用所述电路板2012上的空间位置,减小所述摄像模组20100的尺寸,同时防止所述电子元器件20123上残留的灰尘污染所述感光元件2013。在本发明中,所述感光元件2013下沉的设计方式和一体封装相互结合,减小所述摄像模组20100的尺寸。
参照图25B至图26B,所述一体封装基座2011包括一基座主体20112以及具有一光窗20111,所述光窗20111被设置于所述基座主体20112,为所述感光元件2013提供光线通路。换句话说,所述基座主体20112形成所述光窗20111,为所述感光元件2013提供光线通路。在一些实施例中,所述基座主体20112呈闭合环形,从而形成一封闭的所述光窗20111,在另一些实施例中,所述基座主体20112可以有缺口,连通所述光窗20111和外部,本发明在这方面并不限制。所述基座主体20112的成型材料举例地但不限于尼龙、LCP、PP、树脂等。优选地,所述基座主体20112的成型材料为热固型材料。
进一步,所述电路板2012包括一电路板主体20121以及具有一设置区20122,所述设置区20122被设置于所述电路板主体20121。所述设置区20122也可以称为下沉区。所述感光元件2013被设置于所述设置区20122,使得所述感光元件2013相对所述电路板主体20121的位置下沉。在一些实施例中,所述设置区20122被设置为一凹槽,所述感光元件2013被容纳于所述凹槽,从而使得所述感光元件2013和所述电路板主体20121的相对高度降低。在另一些实施例中,所述设置区20122被设置为一通孔,连通于所述电路板主体20121的两侧。所述感光元件2013被容纳于所述通孔,从而使得所述感光元件2013和所述电路板主体20121 的相对高度降低。在本发明的这个实施例以及附图中,所述设置区20122以通孔为例进行说明,但是本领域的技术人员应当理解的是,本发明在这方面并不限制。所述电路板主体20121举例地但不限于软硬结合板、陶瓷基板(不带软板)、PCB硬板(不带软板)。
所述基座主体20112一体封装所述电路板主体20121和所述感光元件2013,从而固定所述电路板主体20121和所述感光元件2013的相对位置。
所述感光元件2013具有一正面20131和一背面20132,所述正面20131与所述镜头2020方向相对,所述背面20132与所述镜头2020方向相背。所述感光元件2013的所述正面20131具有一感光区201311和一非感光区201312,所述感光区201311用于进行感光作用,所述非感光区201312环绕于所述感光区201311。所述电路板主体20121具有一顶面201212和一底面201211,所述顶面201212与所述镜头2020方向相对,所述底面201211与所述镜头2020方向相背。
所述基座主体20112一体封装所述电路板主体20121的至少部分所述顶面201212和所述感光元件2013的至少部分所述非感光区201312,从而固定所述电路板2012和所述感光元件2013的相对位置。换句话说,通过所述基座主体20112将所述感光元件2013连接于所述电路板主体20121,从而不需要所述电路板主体20121为所述感光元件2013提供支撑作用。而这种下沉一体封装的方式,在传统的COB封装中是难以实现的,结构强度不易达到,且通过镜座难以一体固定线路板和感光芯片。
进一步,在本发明的这个实施例以及附图中,所述设置区20122为通孔,以便于为所述感光元件2013提供更广泛的调整空间,比如使得所述感光元件2013的所述背面20132和所述线路板主体的所述底面201211一致,从而使得所述摄像模组20100的底部平整,便于安装和使用,或者使得所述感光元件2013的所述正面20131和所述电路板主体20121的顶面201212一致,或者使得所述感光元件2013的所述正面20131稍高于所述电路板主体20121的所述顶面201212,或者使得所述感光元件2013的所述正面20131稍低于所述电路板主体20121的所述顶面201212,本领域的技术人员应当理解的是,本发明在这方面并不限制。
在发明的这个实施例以及附图中,以所述设置区20122为通孔为例来进行说明,值得一提的是,当所述设置区20122为通孔时,所述感光元件2013的所述背面20132可以直接显露于外部环境,从而提高所述感光元件2013的散热性能。 在传统COB封装方式中,感光芯片通常叠层贴附于线路板,感光芯片产生的热量需要通过线路板去散热,因此散热性能较差,而当感光芯片的温度较高时,可能影响摄像模组的成像品质。
进一步,所述感光元件2013通过至少一电连接元件20133电连接于所述电路板主体20121,以便于将电信号传递至所述电路板主体20121,所述电连接元件20133举例地但不限于金线、银线、铜线、铝线。所述电路板2012包括至少一电子元器件20123,所述电子元器件20123被设置于所述电路板主体20121。所述电子元器件20123举例地但不限于电阻、电容、驱动元件等。在本发明的这个实施例中,所述电子元器件20123凸出于所述电路板主体20121,而在本发明的其它实施例中,可以不设置所述电子元器件20123或者所述电子元器件20123不凸出于所述电路板主体20121,比如内埋于所述电路板主体20121。在一种实施方式中,所述电子元器件20123通过表面贴装工艺,即SMT(Surface Mounting Technology),设置于所述电路板主体20121。
进一步,所述基座主体20112包覆所述电连接元件20133和所述电子元器件20123,从而使得所述电连接元件20133和所述电子元器件20123不会直接暴露于外部,避免所述电连接元件20133和所述电子元器件20123上残留的灰尘污染所述感光元件2013,且通过所述基座主体20112填充于所述电连接元件20133和所述电子元器件20123周围,充分利用所述电连接元件20133和所述电子元器件20123周围的空间位置,使得所述摄像模组20100的尺寸得以减小。
值得一提的是,所述电连接元件20133的数量和位置可以根据需要设置,比如设置于所述感光元件2013的一侧、两侧、三侧或四侧,或者配合所述电子元器件20123的设置位置进行设置。
进一步,在本发明的这个实施例中,所述摄像模组20100还包括一驱动器2030,如音圈马达、压电马达等,所述镜头2020被安装于所述驱动器2030,以便于通过所述驱动器2030调整所述镜头2020,构成一动焦摄像模组,即AF(Auto Focus)摄像模组。所述驱动器2030可以通过一引脚2031电连接于所述电路板主体20121。所述引脚2031的实施方式可以为单引脚、多引脚、单排引脚、多排引脚等。当然,在本发明的其他实施方式中,参照图27,所述摄像模组20100可以不包括所述驱动器2030,所述镜头2020被直接安装于所述感光组件2010,构成一定焦摄像模组,即FF(Fix Focus)摄像模组。本领域的技术人员应当理 解的是,所述摄像模组20100的类型并不是本发明的限制。所述驱动器2030的具体类型、结构并不是本发明的限制。
所述摄像模组20100还可以包括一滤光元件2040,用于过滤穿过所述镜头2020的光线。所述滤光元件2040举例地但不限于红外截止滤光片、蓝玻璃滤光片、全透片、可见光过滤片。在本发明的这个实施例中,所述滤光元件2040被安装于所述感光组件2010的所述一体封装基座2011,位于所述感光元件2013的光线通路。在本发明的另一些实施例中,所述滤光元件2040还可以被安装于其他部件,比如单独的支架、所述感光元件2013等,本发明在这方面并不限制。
进一步,所述一体封装基座2011的所述基座主体20112具有一安装槽20113,连通于所述光窗20111。在本发明的这个实施例,所述滤光元件2040被安装于所述安装槽20113。更具体地,所述滤光元件2040的边缘延伸进入所述安装槽20113,从而使得所述滤光元件2040被支撑于所述基座主体20112。而在本发明的其他实施例中,一支架被安装于所述安装槽20113,所述滤光元件2040被安装于所述支架。
参照图26A和26B,所述感光组件2010的其中一种形成过程可以为:首先,在所述电路板主体20121上进行表面贴装,将所述电子元器件20123贴装于所述电路板主体20121,所述电子元器件20123的设置位置可以根据需要设置,比如设置在某一侧或几侧;其次,将所述感光元件2013设置于所述电路板2012的所述设置区20122,其中所述设置区20122可以预先形成于所述电路板主体20121,比如在一电路板上开孔形成带有所述设置区20122的所述电路板主体20121,或者采购带有所述设置区20122的所述电路板主体20121;进一步,将所述感光元件2013通过所述电连接元件20133电连接于所述电路板主体20121,以便于实现所述感光元件2013和所述电路板主体20121的电信号传输,比如通过打金线的方式电连接所述感光元件2013和所述电路板主体20121;进一步,形成所述基座主体20112一体封装所述电路板主体20121和所述感光元件2013形成所述光窗20111,并且通过所述基座主体20112包覆所述电子元器件20123和所述电连接元件20133,由此形成可用于安装所述滤光元件2040的所述感光组件2010。

优选地,在本发明的这个实施例中,所述间隔介质20114形成一环形的凸起台阶从而便于在通过所述制造设备20200形成基座主体20112时,支撑所述制造设备20200同时阻挡一体封装材料,以所述间隔介质20114为界限,形成所述基座主体20112。所述间隔介质20114的实施方式举例地但不限于在所述电路板主体20121上通过涂覆胶水形成,也可以通过粘接弹性元件的方式形成,本发明在这方面并不限制。

当然,在本发明的其他实施例中,所述一次基座201121可以不包括所述衬底201121,而仅由所述一次封装基2011212构成,也就是说,在至少部分所述感光元件2013和所述电路板主体20121上一次成型形成所述一次封装基20111212。所述二次基座201122的所述包封基2011221和所述一次封装基2011212形成环形结构,所述二次封装基20111222以所述环形结构为基础一次成型,从而形成所述光窗20111。

值得一提的是,所述电子设备本体30300可以是但不限于智能手机、平板电脑、照相机、安防设备、电视机、电脑设备、可穿戴设备等,附图42B示出的被实施为智能手机的所述电子设备本体30300仅为示例以说明本发明的特征和优势,其并不应被视为对本发明的内容和范围的限制。
下面,在附图43至图57B以及在接下来的描述中将进一步阐述本发明的所述摄像模组30100。另外,在附图49A至图55中和接下来的描述中进一步描述了一成型模具30200,以用于在制造所述摄像模组30100的过程中执行模制工艺。
具体地,所述摄像模组30100包括一模制电路板组件3010和至少一光学镜头3020。所述模制电路板组件3010进一步包括一电路板3011、至少一感光元件3012以及一体地成型于所述电路板3011和所述感光元件3012的一维持部3013。所述光学镜头3020被保持在所述感光元件3012的感光路径,以使被物体反射的光线自所述光学镜头3020进入所述摄像模组30100的内部,并被所述感光元件3012接收和进行光电转化而成像。
值得一提的是,在附图43至图57B和接下来的描述中,以所述摄像模组30100仅包括一个所述感光元件3012和一个所述光学镜头3020为示例,来阐述本发明的所述摄像模组30100的特征和优势,其并不应被视为对本发明的所述摄像模组 30100的内容和范围的限制,在所述摄像模组30100的其他示例中,所述感光元件3012和所述光学镜头3020的数量也可以超过一个,例如所述感光元件3012和所述光学镜头3020均被实施为二个、三个、四个或者更多个。
所述维持部3013一体地成型于所述感光元件3012,从而,所述感光元件3012的平整度可以被所述维持部3013保持,以使所述感光元件3012的平整度不再受限于所述电路板3011,通过这样的方式,不仅能够保证所述感光元件3012的平整度,而且所述摄像模组30100还能够选用厚度更薄的所述电路板3011,例如所述电路板3011可以选用厚度更薄的PCB板或者软硬结合板,甚至所述电路板3011可以选用FPC板,进而,减少所述摄像模组30100的尺寸,尤其是降低所述摄像模组30100的高度尺寸,以使所述摄像模组30100特别适于被应用于追求轻薄化的所述电子设备,而且所述摄像模组30100也特别适于被应用于所述电子设备的前部,以形成前置式摄像模组。
在本发明的所述摄像模组30100的一个具体示例中,被导通的所述感光元件3012和所述电路板3011也可以不直接接触,而是由一体地成型于所述电路板3011和所述感光元件3012的所述维持部3013使所述感光元件3012和所述电路板3011被保持在相对位置。这样,在使用所述摄像模组30100的过程中,即便是所述电路板3011因受热而变形时,也不会影响所述感光元件3012的平整度,通过这样的方式,能够有效地改善所述摄像模组30100的成像品质,并保证所述摄像模组30100的可靠性。
参考附图44和图57A以及图57B,所述维持部3013形成至少一光窗30131,以使所述感光元件3012和所述光学镜头3020分别在所述维持部3013的两侧对应于所述光窗30131,从而使所述感光元件3012通过所述光窗30131与所述光学镜头3020交流,即,所述光窗30131为所述光学镜头3020和所述感光元件3012提供一光线通路,以允许自所述光学镜头3020进入所述摄像模组30100的内部的光线在穿过所述光窗30131后,被所述感光元件3012接收和进行光电转化而成像。换句话说,被物体反射的光线自所述光学镜头3020进入所述摄像模组30100的内部,并在穿过所述维持部3013的所述光窗30131之后被所述感光元件3012接收和进行光电转化而成像。优选地,所述维持部3013的所述光窗30131形成于所述维持部3013的中部,即,所述光窗30131是一个中间穿孔。

值得一提的是,所述外表面30135可以是一个平面,也可以是一个曲面,其根据需要被选择。
在另外的示例中,所述维持部3013还可以具有多个所述外表面30135,以使所述维持部3013的外部形状呈阶梯状。
所述感光元件3012被保持在所述维持部3013的所述结合侧30132,例如所述维持部3013可以通过与所述感光元件3012一体结合的方式,使所述感光元件3012被保持在所述维持部3013的所述结合侧30132,所述光学镜头3020被保持在所述维持部3013的所述贴装侧30133,以使所述感光元件3012和所述光学镜头3020分别在所述维持部3013的两侧光学对应。
优选地,所述维持部3013的所述内表面30134的至少一部分在所述结合侧30132和所述贴装侧30133之间倾斜地延伸。更优选地,所述维持部3013的所述外表面30135也在所述结合侧30132和所述贴装侧30133之间倾斜地延伸。值得一提的是,所述维持部3013的所述贴装侧30133具有一个平面,其平行于所述感光元件3012。
所述维持部3013的所述结合侧30132与所述电路板3011和所述感光元件3012一体地结合,以形成所述模制电路板组件3010。本领域的技术人员可以理解的是,因为所述内表面30134的至少一部分在所述结合侧30132和所述贴装侧30133之间倾斜地延伸,从而使所述光窗30131在所述结合侧30132的开口尺寸小于所述光窗30131在所述贴装侧30133的开口尺寸。
本发明的所述摄像模组30100可以被实施为一动焦摄像模组,参考图57A,所述摄像模组30100进一步包括至少一驱动器3030,例如所述驱动器3030可以被实施为音圈马达、压电马达等,其中所述光学镜头3020被可驱动地设置于所述驱动器3030,所述驱动器3030被组装于所述维持部3013的所述贴装侧30133,从而藉由所述驱动器3030使所述光学镜头3020在所述维持部3013的所述贴装 侧30133被保持在所述感光元件3012的感光路径。也就是说,所述维持部3013用于支撑所述驱动器3030。
本发明的所述摄像模组30100也可以被实施为一定焦摄像模组,例如所述光学镜头3020可以被直接贴装于所述维持部3013的所述贴装侧30133,以使所述光学镜头3020被保持在所述感光元件3012的感光路径。参考附图16B,所述光学镜头3020也可以被贴装于一镜座3050,然后再将所述镜座3050贴装于所述维持部3013的所述贴装侧30133,从而藉由所述镜座3050使所述光学镜头3020在所述维持部3013的所述贴装侧30133被保持在所述感光元件3012的感光路径。因此,本领域的技术人员可以理解的是,在附图43至图57A示出的所述摄像模组30100的实施例中,以所述摄像模组30100被实施为动焦摄像模组为例,说明本发明可以被实施的一种方式,但是并不限制本发明的所述摄像模组30100的内容和范围。
另外,进一步参考附图57A和图57B,所述摄像模组30100可以包括至少一滤光元件3040,其中所述滤光元件3040被贴装于所述维持部3013,以藉由所述维持部3013使所述滤光元件3040被保持在所述光学镜头3020和所述感光元件3012之间,以用于过滤自所述光学镜头3020进入所述摄像模组30100的内部的光线,例如所述滤光元件3040可以是但不限于红外截止滤光片。
进一步地,参考附图45A至图45D,所述维持部3013的所述结合侧30132具有一外结合面30132a和一内结合面30132b,其中所述结合侧30132的所述外结合面30132a和所述内结合面30132b在所述维持部3013形成时一体地形成。所述电路板3011和所述维持部3013的所述外结合面30132a的至少一部分一体结合,所述感光元件3012和所述维持部3013的所述内结合面30132b的至少一部分一体结合,从而形成所述模制电路板组件3010。
值得一提的是,所述维持部3013的所述结合侧30132的所述外结合面30132a所在的平面和所述内结合面30132b所在的平面可以处于同一个水平面,也可以具有高度差,本发明的所述摄像模组30100在这方面不受限制。
更进一步地,继续参考附图45A至图45D,所述维持部3013的所述内表面30134具有一第一内表面30134a、一第二内表面30134b以及一第三内表面30134c,其中所述第一内表面30134a形成于所述结合侧30132,所述第三内表面30134c形成于所述贴装侧30133,所述第二内表面30134b形成于所述第一内表面30134a 和所述第三内表面30134c之间,其中所述第一内表面30134a自所述结合侧30132向所述贴装侧30133方向倾斜地延伸,所述第二内表面30134b所在的平面与所述感光元件3012保持平行,所述第三内表面30134c所在的平面可以垂直于所述第二内表面30134b所在的平面,也可以与所述第二内表面30134b所在的平面形成夹角,即,所述第三内表面30134c自所述贴装侧30133向所述结合侧30132方向倾斜地延伸。优选地,所述第三内表面30134c自所述贴装侧30133向所述结合侧30132方向倾斜地延伸。所述滤光元件3040被贴装于所述维持部3013的所述第二内表面30134b,以使所述滤光元件3040和所述感光元件3012保持水平。
可以理解的是,所述维持部3013的所述第二内表面30134b和所述维持部3013的所述贴装侧30133的贴装面301331具有高度差,且所述第二内表面30134b所在的平面低于所述维持部3013的所述贴装侧30133的所述贴装面301331所在的平面,从而使所述维持部3013形成一贴装槽30130,其中被贴装于所述第二内表面30134b的所述滤光元件3040被容纳于且被保持在所述维持部3013的所述贴装槽30130内,以进一步降低所述摄像模组30100的高度尺寸。

可以理解的是,在本发明的所述摄像模组30100的这个具体示例中,填充在所述基板30111的所述基板内壁301115和所述感光元件3012的所述芯片外侧面 30124之间形成的空间的材料是所述成型材料30400,即,所述维持部3013的一部分形成在所述基板30111的所述基板内壁301115和所述感光元件3012的所述芯片外侧面30124之间。在本发明的所述摄像模组30100的一些示例中,形成在所述基板30111的所述基板内壁301115和所述感光元件3012的所述芯片外侧面30124之间的空间内也可以没有被填充任何材料。在本发明的所述摄像模组30100的其他一些实例中,形成在所述基板30111的所述基板内壁301115和所述感光元件3012的所述芯片外侧面30124之间的空间也可以被填充柔性的材料,例如胶水,从而在模制工艺结束后,得到附图22示出的所述模制电路板组件3010。另外,所述保护元件3015的一部分也可以填充在形成于所述基板30111的所述基板内壁301115和所述感光元件3012的所述芯片外侧面30124之间的空间,从而在模制工艺结束后,得到附图23示出的所述模制电路板组件3010。
附图52至图55示出了所述成型模具30200的拔模过程。当所述成型材料30400在所述成型模具30200的所述成型空间30203内固化后,对所述成型模具30200的所述上模具30201和所述下模具30202执行拔模工序,也即使所述上模具30201和所述下模具30202相分开。
在本发明的所述摄像模组30100中,所述维持部3013的所述第一内表面30134a自所述维持部3013的所述结合侧30132向所述贴装侧30133方向倾斜地延伸,以在所述第一内表面30134a和所述感光元件3012的光轴之间形成所述第一夹角α,且所述第一夹角α是锐角,从而在所述成型模具30200被执行拔模的瞬间,在所述维持部3013的所述第一内表面30134a和所述上模具30201的所述模具内壁302013之间具有摩擦力f1,当所述成型模具30200的所述上模具30201稍微产生相对于所述下模具30202的位移后,在所述维持部3013的所述第一内表面30134a和所述上模具30201的所述模具内壁302013之间就不会产生摩擦力,通过这样的方式,一方面,能够防止所述上模具30201的所述模具内壁302013摩擦所述维持部3013的所述内表面30134而刮伤所述维持部3013的所述内表面30134,另一方面,能够防止所述上模具30201的所述模具内壁302013摩擦所述维持部3013的所述内表面30134而产生作用于所述维持部3013的拉力,从而保证所述维持部3013和所述电路板3011与所述感光元件3012结合的可靠性。
也就是说,所述维持部3013的所述第一内表面30134a倾斜地延伸,不仅能够保护所述维持部3013的所述第一内表面30134a的光洁度,而且还能够便于所 述成型模具30200被脱模。
在本发明的所述摄像模组30100中,所述维持部3013的所述第三内表面30134c自所述维持部3013的所述贴装侧30133向所述结合侧30132方向倾斜地延伸,以在所述第三内表面30134c和所述感光元件3012的光轴之间形成所述第三夹角γ,且所述第三夹角γ是锐角,从而在所述成型模具30200被执行拔模的瞬间,在所述维持部3013的所述第三内表面30134c和所述上模具30201的所述模具内壁302013之间具有摩擦力f3,当所述成型模具30200的所述上模具30201稍微产生相对于所述下模具30202的位移后,在所述上模具30201的所述模具内壁302013和所述维持部3013的所述第三内表面30134c之间就不会产生摩擦力,通过这样的方式,一方面,能够防止所述上模具30201的所述模具内壁302013摩擦所述维持部3013的所述内表面30134而刮伤所述维持部3013的所述内表面30134,另一方面,能够防止所述上模具30201的所述模具内壁302013摩擦所述维持部3013的所述内表面30134而产生作用于所述维持部3013的拉力,从而保证所述维持部3013和所述电路板3011与所述感光元件3012结合的可靠性,再一方面,能够保证所述第二内表面30134b的水平度。
优选地,在本发明的所述摄像模组30100中,所述维持部3013的所述外表面30135自所述维持部3013的所述结合侧30132向所述贴装侧30133倾斜地延伸,从而在所述维持部3013的所述外表面30135和所述感光元件3012的光轴之间形成所述第二夹角β,且所述第二夹角β是锐角。相似地,所述维持部3013的所述外表面30135倾斜地延伸,在所述成型模具30200被拔模的过程中,在所述成型模具30200被执行拔模的瞬间,在所述维持部3013的所述外表面30135和所述上模具30201的所述外导槽成型周壁3020122a之间产生摩擦力f2,当所述成型模具30200的所述上模具30201稍微产生相对于所述下模具30202的位移后,在所述维持部3013的所述外表面30135和所述上模具30201的所述外导槽成型周壁3020122a之间就不会产生摩擦力,这样,不仅能够方便拔模,而且能够保证所述维持部3013的所述外表面30135的光洁度,从而提高所述摄像模组30100的产品良率。

附图65示出了所述模制电路板组件3010的一个变形实施方式,其中在所述维持部3013成型之前,也可以将所述滤光元件3040重叠地设置于所述感光元件3012,从而在模制过程中,使所述维持部3013、所述滤光元件3040、所述感光元件3012和所述电路板3011一体地成型。
附图66示出了所述模制电路板组件3010的一个变形实施方式,其中所述维持部3013的所述内表面30134是一个完整的面,所述滤光元件3040和所述驱动器3030分别被贴装于所述维持部3013的所述贴装侧30133。具体地,所述维持部3013的所述贴装侧30133的所述贴装面301331具有一外贴装面301331a和一内贴装面301331b,其中所述外贴装面301331a和所述内贴装面301331b一体地形成,且所述外贴装面301331a和所述内贴装面301331b优选为处于同一个平面。所述贴装侧30133的所述外贴装面301331a自所述外表面30135向所述内表面30134方向延伸,所述贴装侧30133的所述内贴装面301331b自所述内表面30134向所述外表面30135方向延伸。所述驱动器3030被贴装于所述贴装侧30133的所述外贴装面301331a的至少一部分,以使被组装于所述驱动器3030的所述光学镜头3020被保持在所述感光元件3012的感光路径,所述滤光元件3040被贴装于所述贴装侧30133的所述内贴装面301331b的至少一部分,以使所述滤光元件3040被保持在所述感光元件3012和所述光学镜头3020之间。
本领域的技术人员可以理解的是,所述维持部3013的所述内表面30134的倾斜度受限于所述引线3014的打线方向,当所述引线3014的打线方向是从所述感光元件3012至所述电路板3011时,所述维持部3013的所述内表面30134与所述感光元件3012的光轴之间的所述第一夹角α较小,当所述引线3014的打线方向是从所述电路板3011至所述感光元件3012时,所述维持部3013的所述内表面30134与所述感光元件3012的光轴之间的所述第一夹角α较大。
本领域的技术人员还可以理解的是,如果所述第一夹角α过大,则在藉由所述成型模具30200模制所述模制电路板组件3010时,可能会损坏所述引线3014,且在所述维持部3013成型后,所述引线3014会裸露在所述维持部3013的所述内表面30134,从而在成像时,自所述光学镜头3020进入所述摄像模组30100 的内部的光线会被所述引线3014反射而在所述摄像模组30100的内部产生杂散光,以至于影响所述摄像模组30100成像。如果所述第一夹角α过小,则所述成型模具30200不易拔模,且在所述成型模具30200拔模时,会损坏所述维持部3013和使所述维持部3013产生碎屑等颗粒而污染所述感光元件3012的所述感光区域301212。
另外,所述第二夹角β和所述第三夹角γ的值也均不宜过大和过小,否则会导致所述维持部3013无法被贴装所述滤光元件3040和所述驱动器3030或者所述成型模具30200不方便拔模。
也就是说,所述第一夹角α、所述第二夹角β和所述第三夹角γ的最大限值和最小限值。所述第一夹角α的范围是1°~85°。所述第二夹角β的范围是1°~65°。所述第三夹角γ的范围是1°~60°。可选地,所述第一夹角α的范围是35°~75°
