具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
附图中所示的流程图仅是示例说明,不是必须包括所有的内容和操作/步骤,也不是必须按所描述的顺序执行。例如,有的操作/步骤还可以分解、组合或部分合并,因此实际执行的顺序有可能根据实际情况改变。
大尺寸倒装焊器件在焊接过程中,经常发生短路和锡珠等不良问题。本申请针对该技术问题,提出在焊接的第一主器件和第一电路板之间设置支撑件,通过支撑件确定第一主器件和第一电路板之间的间隙高度。这里确定间隙高度 主要有两层意思:一个是通过支撑件调整间隙高度,以保证在合适的间隙高度使第一主器件和第一电路板之间焊接良好,不出现短路和锡珠等不良问题;另一个是固定第一主器件和第一电路板之间的间隙高度,防止间隙高度发生变化,导致短路和锡珠等不良问题。其中,该大尺寸倒装焊器件可用于包括但不限于相机、可移动平台的子设备中。可移动平台包括但不限于无人飞行器、手持云台、云台车,在此不做限定。
下面结合附图,对本申请的一些实施方式作详细说明。在不冲突的情况下,下述的实施例及实施例中的特征可以相互组合。
参见图1,图1是本申请电子封装组件一实施例的结构示意图,该电子封装组件包括:第一主器件1、第一电路板2以及支撑件3。
第一电路板2与第一主器件1层叠设置。支撑件3设置在第一主器件1和第一电路板2之间,支撑件3分别与第一主器件1和第一电路板2连接,用于确定第一主器件1和第一电路板2之间的间隙高度,以使间隙高度与支撑件3的高度相匹配。支撑件3的高度可以起到固定和调节第一主器件1和第一电路板2之间的间隙高度的作用。在一些实施例中,第一主器件1和第一电路板2之间的间隙高度是可调的,即第一主器件1和第一电路板2之间的间隙高度可以依据支撑件3的高度调整。在另一些实施例中,第一主器件1和第一电路板2之间的间隙高度是不可调的,即第一主器件1和第一电路板2之间的间隙高度可以依据支撑件3的高度进一步固定,防止第一主器件1和第一电路板2之间的间隙高度因外界条件的改变而发生改变。
同时,第一主器件1和第一电路板2利用各自设置的第一焊接部11、第二焊接部21按照正常的电连接方式通过焊点4连接,以实现电连接。其中,第一电路板2的第一侧与第一主器件1的第一侧相对设置。第一主器件1的第一侧间隔设置多个第一焊接部11。第一电路板2的第一侧间隔设置多个第二焊接部21,多个第二焊接部21与多个第一焊接部11相对设置。相对设置的第一焊接部11与第二焊接部21通过焊点4相连接,以实现第一主器件1和第一电路板2的电连接。
本申请实施例提供了一种电子封装组件,通过在第一主器件1和第一电路板2之间设置支撑件3,支撑件3分别与第一主器件1和第一电路板2连接, 用于确定第一主器件1和第一电路板2之间的间隙高度,以使间隙高度与支撑件3的高度相匹配,由于间隙高度由支撑件3的高度确定,并不由第一主器件1和第一电路板3之间的共面性确定,且支撑件3的高度相当于固定间隙高度,能够避免间隙高度发生变化,通过这种方法,能够避开第一主器件1和第一电路板2之间的共面性好坏的影响,能够避免外界条件对第一主器件1和第一电路板2之间间隙高度的影响,从而能够保证第一焊接部11与第二焊接部21的焊接质量,保证焊点4均匀,避免短路和锡珠等不良问题。
在本申请实施例中,第一主器件1包括但不限于倒装焊器件(例如:BGA器件、CSP器件、POP器件、LGA器件,等等),特别是大尺寸的倒装焊器件(例如对角线长度在80mm左右的倒装焊器件),第一主器件1还可以是另一电路板(例如:印刷电路板、柔性电路板、软硬结合板,等等)。第一电路板2包括但不限于印刷电路板、柔性电路板、软硬结合板,等等。
印刷电路板,又称印制电路板,是电子元器件电气连接的提供者;按照印刷电路板的层数可分为单面板、双面板、四层板、六层板以及其他多层电路板。采用印刷电路板的主要优点是可以大大减少布线和装配的差错,能够提高自动化水平和生产劳动率。
柔性电路板(FPC,Flexible Printed Circuit Board),简称“软板",是用柔性的绝缘基材(主要是聚酰亚胺或聚酯薄膜)制成的印刷电路板,它可以自由弯曲、卷绕、折叠,还具有良好的散热性和可焊性以及易于装连、综合成本较低等优点;柔性电路板有单面、双面和多层板之分。利用FPC可大大缩小电子产品的体积,适用电子产品向高密度、小型化、高可靠方向发展的需要。
在本实施例中,可以作为第一主器件1的电子器件范围广泛,可以作为第一电路板2的电路板范围也广泛,这使得本申请实施例的电子封装组件应用范围很广泛。
其中,当第一主器件1和第一电路板2之间的间隙高度是可调的时候,第一电路板2与第一主器件1可以层叠并间隔设置。当第一主器件1和第一电路板2之间的间隙高度是不可调的时候,第一电路板2与第一主器件1仅仅是层叠设置。
具体地,由于BGA器件在底部制作有焊球作为电路的I/O端与电路板互 接,如果第一主器件1是BGA器件,第一电路板2与BGA器件只能是层叠设置。当第一主器件1不是BGA器件时,第一电路板2与第一主器件1可以层叠间隔设置。
当第一电路板2与第一主器件1可以层叠并间隔设置时,能够通过支撑件3调节第一电路板2与第一主器件1之间的间隙高度。当第一电路板2与第一主器件1仅仅是层叠设置时,能够通过支撑件3固定第一电路板2与第一主器件1之间的间隙高度,防止第一电路板2与第一主器件1之间的间隙高度发生变化。
第一主器件1的尺寸与第一电路板2的尺寸匹配,即本申请实施例的电子封装组件10对第一主器件1的尺寸与第一电路板2的尺寸并不做限定,进一步扩大应用范围。在一些实施例中,第一主器件1的尺寸可以大于第一电路板2的尺寸。在另一些实施例中,第一主器件1的尺寸可以等于第一电路板2的尺寸。在又一些实施例中,第一主器件1的尺寸可以小于第一电路板2的尺寸。
支撑件3的作用是确定第一主器件1和第一电路板2之间的间隙高度,能够起到确定间隙高度的结构均可以作为本申请实施例中的支撑件3,在此对支撑件3的结构不做限定。
支撑件3的设置位置不做限定。在一实施例中,支撑件3的设置位置靠近第一主器件3的边缘位置。支撑件3设置在靠近第一主器件1的边缘位置,一方面在边缘位置设置支撑件3更加容易,另一方面,不会影响第一主器件1与第一电路板2之间的正常焊接。
支撑件3的数量和形状不做限定。在一些实施例中,支撑件3的数量是一个,其形状包括如下至少一种:“口”字形、三角形、“U”字形。在本实施例中,支撑件3的数量少,成本低廉,支撑件3的形状简单,容易获得。在另一些实施例中,支撑件3的数量是多个,其形状可以是柱状,多个支撑件间隔设置在第一主器件1和所述第一电路板2之间。在本实施例中,支撑件3的形状简单,非常容易获得,可选择的范围广大。
支撑件3的高度不做限定,根据具体实际应用确定。在一些实施例中,支撑件3的高度可以一致。其中,当支撑件3的数量是多个时,多个支撑件3的高度一致。由于多个支撑件3高度一致,这使得支撑件制作方便,且能够确 定第一主器件1和所述第一电路板2之间间隙高度保持一致。进一步,每个支撑件的高度范围是0.2-0.4mm,即间隙高度的范围是0.2-0.4mm,例如:0.2mm、0.3mm、0.4mm,等等。在另一些实施例中,支撑件的高度可以不一致。例如,当第一主器件1的第一侧和/或第一电路板2的第一侧凸凹不平的时候,为了使第一主器件1焊接到第一电路板2后尽量保持水平或者平行,支撑件3的高度可以不一致。
在一具体应用中,第一主器件1的尺寸小于第一电路板2的尺寸时,支撑件3包括芯片器件,本实施例中芯片器件包括可以贴装的元器件,也包括非贴装的元器件,例如:未封装的晶片(die)。进一步,支撑件3包括贴片元器件。贴片元器件包括但不限于:各种可贴装的小尺寸的元器件,例如01005、0201、0805等等。
在另一具体应用中,当第一主器件1的尺寸等于或者大于第一电路板2的尺寸时,支撑件3包括治具31。通常情况下,治具31是一个木工、铁工、钳工、机械、电控以及其他一些手工艺品的大类工具,主要是作为协助控制位置和/或动作的一种工具。在本实施例中,治具31是用来确定第一主器件1和第一电路板2之间的间隙高度,以使间隙高度与支撑件3的高度相匹配。
具体地,参见图2,在一实施例中,治具31包括凹槽311和凹槽311边缘的凸起312,凹槽311用于容置第一电路板2,凸起312用于确定第一主器件1和第一电路板2之间的间隙高度。由于治具31的凹槽311用于容置第一电路板2,这使得治具31除了能够确定间隙高度外,还能够固定第一电路板2,防止第一电路板2发生移动。进一步,凹槽311呈方形,第一电路板2能够容置在凹槽311的底部。第一电路板2能够容置在凹槽311的底部,这使得第一电路板2的位置更加稳固。
第一焊接部11和第二焊接部21的作用是进行焊接并通过焊接形成的焊点4实现电连接,只要相对设置的第一焊接部11和第二焊接部21结构匹配,能够通过焊接形成的焊点4实现电连接即可,在此对第一焊接部11和第二焊接部21结构不做限定。
具体地,第一焊接部11包括第一焊盘或第一焊球。第二焊接部21包括第二焊盘或第二焊球。当第二焊接部21包括第二焊球时,可以在第一电路板2 上制作第二焊球作为第二焊接部21。焊盘和焊球均是实际应用中比较广泛的焊接部结构,这使得本申请实施例的电子封装组件10对采用通用焊接部结构的第一焊接部11和第二焊接部21均是适用的。当然,第一焊接部11和第二焊接部21还可以是其他结构,例如焊柱、焊针,等等。
需要注意的是,通常情况下,焊球与焊盘匹配;而焊盘可以与焊盘、或盘球匹配。以通用的焊接部结构为例,在一实际应用中,第一焊接部11是第一焊盘,第二焊接部21是第二焊盘,焊点4是第一主器件1的第一焊盘与第一电路板2的第二焊盘通过膏状焊料焊接而形成的。例如:第一主器件1是LGA器件或者印刷电路板的时候,第一焊接部11可以是第一焊盘。第一电路板2是印刷电路板或者柔性电路板的时候,第二焊接部21可以是第一焊盘。
在另一实际应用中,第一焊接部11是第一焊球,第二焊接部21是第二焊盘,焊点4是第一主器件1的第一焊球与第一电路板2的第二焊盘焊接而形成的。例如:第一主器件1是BGA器件的时候,第一焊接部11可以是第一焊球。或者第一主器件1是印刷电路板的时候,可以专门制作第一焊球作为第一焊接部11。第一电路板2是印刷电路板或者柔性电路板的时候,第二焊接部21可以是第一焊盘。
具体地,膏状焊料包括锡膏。膏状焊料俗称焊膏,目前焊膏的主要成分是锡铅合金,故也称锡铅焊膏或焊锡膏(也叫锡膏)。焊膏应该有足够的粘性,可以把SMT元器件粘附在印刷电路板上,直到回流焊完成。焊锡膏由焊粉和糊状助焊剂组成。焊粉是合金粉末,是焊膏的主要成分。焊粉的合金组分、颗粒形状和尺寸对焊膏的特性和焊接的质量(焊点的润湿、高度和可靠性)产生关键性的影响。
锡铅共晶焊锡膏在焊接电子设备中应用最为广泛。金锡焊料对于金导体表面有很好的焊接质量,常用于焊接高密度的SMT元器件。在锡铅合金中加入银,可以增加焊料的强度,提高耐热性和润湿性,减少对镀银导线表面的浸析。在锡铅合金中加入铋,既可以提高强度,又可以降低熔点,便于在低温中进行焊接。铅铟焊料有很好的延展性,对金导体的浸析率较低,适用于SMT元器件和一般电路的焊接。
在一实施例中,多个第一焊接部11可以设置在第一主器件1的一表面的 整个区域,也可以设置在第一主器件1的一表面的一部分区域。具体来说,第一主器件1包括第一表面12,第一主器件1的第一表面12位于第一主器件1的第一侧。在一实际应用中,第一主器件1的第一表面12的整个区域间隔设置多个第一焊接部11。在另一实际应用中,第一主器1件的第一表面12的部分区域间隔设置多个第一焊接部11。
通常情况下,为了增加第一主器件1与第一电路板2之间的连接稳定性,可以使多个第一焊接部11间隔设置在第一主器件1的第一表面12的整个区域;当需要增加电信号的传递速度时,可以增加第一主器件1的第一焊接部11数量,并使多个第一焊接部11间隔设置在第一主器件1的第一表面12的整个区域。在另外情况下,为了减少第一主器件1与第一电路板2之间的焊点4连接,可以使多个第一焊接部11间隔设置在第一主器件1的第一表面12的部分区域。
在一实施例中,多个第二焊接部21可以设置在第一电路板2的一表面的整个区域,也可以设置在第一电路板2的一表面的一部分区域。具体来说,第一电路板2包括第一表面22,第一电路板2的第一表面22位于第一电路板2的第一侧。在一实际应用中,第一电路板2的第一表面22的整个区域间隔设置多个第二焊接部21。在另一实际应用中,第一电路板2的第一表面22的部分区域间隔设置多个第二焊接部21。
通常情况下,为了增加第一主器件1与第一电路板2之间的连接稳定性,可以使多个第二焊接部21间隔设置在第一电路板2的第一表面22的整个区域;当需要增加电信号的传递速度时,可以增加第一电路板2的第二焊接部21数量,并使多个第二焊接部21间隔设置在第一电路板2的第一表面22的整个区域。在另外情况下,为了减少第一主器件1与第一电路板2之间的焊点4连接,可以使多个第二焊接部21间隔设置在第一电路板2的第一表面22的部分区域。
在实际应用中,第一电路板2的第二侧也是可以连接电子器件的,第一电路板2的第二侧是与第一电路板2的第一侧相对的一侧。
参见图3,第一电路板2的第二侧连接有电子器件5,进一步电子器件5包括第二电路板,也可以是其它的电子器件。其中,第二电路板包括印刷电路板,也可以包括柔性电路板,等等。由于第一电路板2的第二侧可以连接其它电子器件5,通过这种方式,能够增加电子封装组件10的其它功能。
下面以第一主器件1包括LGA器件、BGA器件、或印刷电路板为例,以第一电路板2包括印刷电路板为例来具体说明本申请实施例的电子封装组件10。
在一实施例中,第一主器件1包括LGA器件,特别是对角线长度在70-90mm的LGA器件。第一电路板2包括印刷电路板PCB。
在实际应用中,由于LGA器件与PCB的共面度较差,经常发生开短路和锡珠等不良问题,造成PCBA返修。
本申请实施例中,在LGA器件与PCB之间设置支撑件3,增大LGA器件与PCB之间的间隙,在焊接的时候,同时增加焊料,可以非常有效地避免发生开短路和锡珠等不良问题,从而提升PCBA的加工良率。在实际应用进行验证,在LGA器件与PCB之间设置支撑件3,增大LGA器件与PCB之间的间隙,贴装近几百个单板,没有发现不良。而之前,LGA器件与PCB焊接,不良率在50%左右。增大LGA器件与PCB之间的间隙,对PCBA的温度循环可靠性也有提升。
在另一实施例中,第一主器件1包括BGA器件,特别是大尺寸的BGA器件。第一电路板2包括印刷电路板PCB。
BGA器件在底部制作有焊球作为电路的I/O端与印刷电路板互接。在实际应用中,容易发生BGA器件翘曲变形,参见图4,在冷却过程中或者加热过程中,由于BGA器件和印刷电路板之间缩小的程度(冷却过程)或者膨胀的程度(加热过程)不一致,从而发生BGA器件翘曲变形;参见图5,BGA器件翘曲变形容易导致焊球开路(图中A的位置),使BGA器件与印刷电路板之间的焊接失败。
在BGA器件与印刷电路板之间设置支撑件3,由于支撑件3分别与BGA器件和印刷电路板连接,其作用就是用于确定BGA器件和印刷电路板之间的间隙高度,以使该间隙高度与支撑件3的高度相匹配。即,通过支撑件3能够保证BGA器件和印刷电路板之间的间隙高度与支撑件3的高度匹配,换句话说,支撑件3能够固定BGA器件和印刷电路板之间的间隙高度,能够防止BGA器件和印刷电路板之间的间隙高度因外界条件变化(例如冷却过程或加热过程)而发生变化,从而能够避免发生BGA器件翘曲变形,进而能够避免发生焊球 开路和焊接失败等不良问题。
在又一实施例中,第一主器件1包括印刷电路板。第一电路板2包括印刷电路板PCB。即印刷电路板与印刷电路板之间通过焊接实现电连接的时候,也可以设置支撑件3。支撑件3调节印刷电路板与印刷电路板之间的间隙高度至合适的间隙高度,以使印刷电路板与印刷电路板之间焊接质量良好。通过这种方式,能够非常有效地避免发生开短路和锡珠等不良问题,从而提升加工良率。
