发明内容
本申请提供了一种电子模块及电子设备,用以缓解当两个组件在相对滑动时,两个组件之间的端子间距发生变化的技术问题,以使两个组件之间通过端子以较高的速度传输数据时具有较好的信号完整性。
第一方面,提供了一种电子模块,该电子模块应用于手机、电脑或交换机等电子设备中,并且包括第一组件、第二组件,以及,多个端子;在将第一组件与第二组件组装时,第一组件沿第一预设方向与第二组件滑动配合、并可相对于第二组件锁定在第一设定位置,其中,第一组件朝向第二组件的面具有多个第一焊盘;上述多个端子与上述多个第一焊盘 中的至少部分一一对应,每个端子包括主体部及与该主体部连接的第一弯折部,其中,主体部与第二组件固定连接,第一弯折部与对应的第一焊盘抵接;在第一组件沿第一预设方向相对于第二组件滑动时,第一组件施加给每个端子的第一弯折部的摩擦力的力矩小于或等于主体部施加给第一弯折部的扭矩;因此,对于每个端子来说,第一组件不容易带动第一弯折部绕对应的主体部转动,不同的端子的第一弯折部之间的距离不易发生改变,每个端子对的差分阻抗不易变大,不同端子对之间串扰不易增加,第一组件和第二组件之间通过端子传输信号时,在高速下也能够保持较好的SI(信号(Signal)Integrity,信号完整性)性能。
例如,在一个具体的实施方式中,在每个端子中,当主体部和第一弯折部的材质均为铜合金和磷青铜等常用材质,且第一弯折部的延伸方向所在直线与第一预设方向所在直线的夹角介于0°至15°之间时,可以确保第一组件施加给第一弯折部的摩擦力的对应的力臂较小,该摩擦力施加给每个端子的第一弯折部的力矩不足以克服主体部施加给第一弯折部的扭矩。
在具体设置端子时,端子的摆放方式影响第一组件的受力,例如,多个端子呈阵列分布,沿第一预设方向分布的每一行端子中,一部分端子的第一弯折部与另一部分端子的第一弯折部的相向设置或者相背设置,如此,同一行端子施加给第一组件的摩擦力的至少部分分力相反,因此,第一弯折部朝向相反的端子对第一组件的摩擦力可以相互抵消至少一部分,以尽量保持第一组件的受力平衡,每个端子的第一弯折部与第一组件中对应的第一焊盘之间不易发生错位。
在一个具体的实施方式中,沿第一预设方向分布的每一行端子中,第一弯折部朝向第一预设方向的端子数量与第一弯折部背离第一预设方向的端子的数量相等,以确保同一行端子中的第一弯折部朝向不同的端子对第一组件摩擦力能够充分抵消。
为了进一步提升第一组件和第二组件通过端子传输信号时的SI性能,在一个具体的实施方式中,沿第一预设方向分布的每一行端子中,第一弯折部朝向第一预设方向的端子连续设置,且第一弯折部背离第一预设方向的端子连续设置,以确保对于第一弯折部朝向相同的不同端子,主体部之间的距离和第一弯折部之间的距离都趋于均匀。
上述第一组件的形式可以有多种,在一个具体的实施方式中,第一组件包括封装基板和芯片,封装基板包括基板本体和多个第一焊盘,多个第一焊盘与芯片分别设置在基板本体相对的两个表面;且芯片与多个第一焊盘电连接。除此之外,第一组件还可以是具有第一焊盘的寄生电路板。

除了在主体部的用于朝向第一组件的一端设置第一弯折部外,在一个具体的实施方式中,每个端子还包括连接于主体部远离第一弯折部的一端的第二弯折部,每个端子的第二弯折部与一个第二焊盘抵接;安装底座沿第二预设方向与电路板本体滑动配合、并可相对于电路板本体锁定在第二设定位置;当安装底座沿第二预设方向相对于电路板本体滑动时,电路板本体施加给每个端子的第二弯折部的摩擦力的力矩小于或等于主体部施加给第二弯折部的扭矩,以使第二弯折部不易相对于主体部发生转动,进一步确保端子在传输信号 时的SI性能。
例如,在一个具体的实施方式中,在每个端子中,当主体部和第二弯折部的材质均为铜合金和磷青铜等常用材质,每个端子的第二弯折部的延伸方向所在直线与第二预设方向所在直线的夹角介于0°至15°之间,可以确保电路板本体施加给第二弯折部的摩擦力对应的力臂较小,该摩擦力施加给每个端子的第二弯折部的力矩不足以克服主体部施加给第二弯折部的扭矩。
为了确保每个端子的受力平衡,使每个端子都能够与对应的第一焊盘和第二焊盘精准对位,在一个具体的实施方式中,在每个端子中,第一弯折部的延伸方向与第二弯折部的延伸方向相反。
在一个具体的实施方式中,电路板还包括形成于电路板本体的多条走线,多条走线与至少部分端子一一对应地信号连接;其中,当多个端子呈阵列分布时,每条走线沿相邻的两列和/或两列端子之间的中间位置延伸,并且平行于该走线两侧的端子的排列方向,有利于避免走线离其中一侧的端子过近,影响该端子的性能。
在一个具体的实施方式中,封装基板的至少一组相对的两个侧边中,每条侧边的中间与安装底座定位连接,每个端子距离对应的定位凸块距离更近,以减小端子与第一焊盘对位的累积误差。
第二方面,提供了一种电子设备,该电子设备可以是手机、电脑或交换机等,并且该电子设备包括存储模块和上述技术方案所述的电子模块,电子模块中的第一组件与存储模块电连接;通过使第一组件沿第一预设方向相对于第二组件滑动时,第一组件施加给每个端子的第一弯折部的摩擦力的力矩小于或等于主体部施加给第一弯折部的扭矩,对于每个端子来说,第一组件不容易带动第一弯折部绕对应的主体部转动,不同的端子的第一弯折部之间的距离不易发生改变,第一组件和第二组件之间通过端子传输信号时,在高速下也能够保持较好的SI(信号(Signal)Integrity,信号完整性)性能,从而,提升电子设备的性能。

图3a表示出了当未将封装基板12安装于安装底座21时图1中n1列的端子30的俯视图(沿Z轴负方向观察的视图)的放大图,由图3a可知,沿Y轴负方向,n1列的多个端子30依次为接地端子地(Ground)、信号端子信号(Signal)1P(+)、信号端子信号(Signal)1N(-)、接地端子地(Ground)、信号端子信号(Signal)2P(+)、信号端子信号(Signal)2N(-)和接地端子地(Ground)。其中,信号端子信号(Signal)1P(+)和信号端子信号(Signal)1N(-)组成一个P/N端子对。信号端子信号(Signal)2P(+)和信号端子信号(Signal)2N(-)组成一个P/N端子对。在自然状态下,n1列的每个端子30的弯折部31的延伸方向相互平行,均为T方向,如此,可确保n1列端子30中的每相邻两个端子30的弯折部31之间的距离适中。同时结合图1,但当欲将封装基板12安装于安装底座21时,需要沿着安装方向P推动封装基板12相对于安装底座21滑动,每个端子30的弯折部31会受到来自封装基板12的沿安装方向P的摩擦力,由于现有技术中每个端子30的弯折部31的延伸方向T与安装方向P之间存在夹角(例如该夹角为45°),弯折部31容易失去平衡,易在上述焊盘的摩擦力的作用下发生旋转(旋转轴平行于Z轴),每个端子30的弯折部31在封装基板12上的焊盘的摩擦力作用下,会向不同方向发生不同程度的偏移。
图3b表示出了当封装基板12沿着安装方向P相对于安装底座21滑动至设定位置、并被安装到安装槽内后n1列端子的俯视图的放大图。参考图3b,图1中的n1列的多个端子30中,信号端子信号(Signal)1P(+)的弯折部31和信号端子信号(Signal)1N(-)的弯折部31相互远离,导致信号端子信号(Signal)1P(+)和信号端子信号(Signal)1N(-)组成的端子对的差分阻抗变大,信号端子信号(Signal)2P(+)的弯折部31和信号端子信号(Signal)1N(-)弯折部31相互靠近,导致不同的P/N端子对之间串扰增加,以上两个因素都会导致在芯片11和电路板22之间通过端子30传输数据时,信号容易失真,特别是当高速传输数据时,信号失真情况越严重,即SI(Signal Integrity,信号完整性)性能劣化,只能适应25Gbps以下速率的数据传输速度。
为了解决上述技术问题,本申请实施例提供了一种电子模块:
示例性地,图4a表示出了本申请实施例提供的电子模块中第一组件装配于第二组件时的示意图。请参考图4a,本申请实施例提供的电子模块包括第一组件100、第二组件200和多个端子300。第一组件100包括芯片110和封装基板120,芯片110位于封装基板120的Z轴正方向一侧,其中,该芯片110可以是CPU(中央处理器,Central Processing Unit)和缓存等。第二组件200包括安装底座210和电路板220,其中,安装底座210放置于电路板220的Z轴正方向一侧,封装基板120安装于安装底座210背离电路板220的一侧。每个端子300贯穿安装底座210以实现对封装基板120和电路板220的信号连接。
示例性地,图5表示出了图4a中封装基板120的仰视图(沿Z轴方向观察的视图),请参考图5,封装基板120包括基板本体121和分布于基板本体121底面(Z轴负方向上的表面,该表面示例性地平行于XOY面)的多个第一焊盘122。示例性地,上述多个第一焊盘122分成四组,这四组第一焊盘122一一对应地分布于基板本体121底面角部的E1区域、F1区域、G1区域和H1区域内。每组第一焊盘122均呈阵列分布,其中,定义行方向为X轴方向,列方向为Y轴方向,其中,E1区域中的每行第一焊盘122与F1区域中的一行第一焊盘122对齐设置,G1区域中的每一行第一焊盘122与H1区域中的一行第一焊盘122对齐设置,E1区域中的每列第一焊盘122与G1区域中的一列第一焊盘122对齐设置,F1区域中的每一列第一焊盘122与H1区域中的一列第一焊盘122对齐设置。但以上各组第一焊盘122的分布方式仅仅是示例性地,也可以是以其他形式分布,如所有第一焊盘122连续设置,且整体呈阵列分布。其中,芯片110安装于基板本体121的顶面(Z轴正方向上的表面),并且,芯片110通过引脚等方式与基板本体121上的一些触点连接,实现芯片110与基板本体121另一侧的多个第一焊盘122电连接,芯片110与第一焊盘122的电连接方式可以是现有技术中已知的常用的连接方式,在此不再赘述。基板本体121与X轴平行的两个相对的侧边中间位置具有向基板本体121内部凹陷的定位凹陷(123a和123b)。
示例性地,图6表示出了图4a中安装底座210的结构示意图。请参考图6,安装底座210包括板状的底座本体211、位于底座本体211角部边缘的限位挡板(213e、213f、213g和213h),位于与X轴平行的两个相对的侧边中间位置上的定位凸块(214a和214b),以及,沿与X轴平行的两个相对的侧边分别延伸的加强结构(215a和215b),加强结构(215a和215b)一方面可以对定位凸块(214a和214b)的结构强度进行加强,另一方面也可以对基板本体121具有初步限位作用。示例性地,底座本体211厚度方向上相对的两个表面均平行于XOY面,其中,在底座本体211靠近四个角部的位置分别具有E2区域、F2区 域、G2区域和H2区域,这四个区域中的每个区域中分别阵列分布有一组端子固定腔212。
示例性地,图7表示出了图4a中电路板220的俯视图。请参考图7,电路板220包括电路板本体221和分布于电路板本体221的安装面S2(示例性地,该安装面S2平行于XOY面)的多个第二焊盘222。电路板本体221具有E3区域、F3区域、G3区域和H3区域四个区域,上述多个第二焊盘222分为四组,每组第二焊盘222阵列式分布于上述四个区域中的一个区域。其中,在一个具体的实施方式中,第二焊盘222的焊接方式采用NSMD(铜箔定义焊盘)的方式,相对于SMD(阻焊定义焊盘),能更好地提高第二焊盘222的位置精度,并且降低端子300与第二焊盘222的焊接难度。
示例性地,图8表示出了图4a中端子300的结构示意图。示例性地,端子300包括金属构件310和焊球320,金属构件310包括第一弯折部312和条状(仅仅是示例性的)的主体部311,第一弯折部312与主体部311的一端连接(如一体式连接),焊球320与主体部311的另一端连接。
图4b表示出了图4a中A处局部放大图,结合图4a、图4b、图6和图8,示例性地,在对第一组件100和第二组件200进行组装时,根据实际需要,在部分或者全部端子固定腔212中,每个端子固定腔212中放置一个金属构件310,其中,金属构件310的主体部311贯穿于对应的端子固定腔212中,以与底座本体211固定连接,第一弯折部312暴露于底座本体211顶面(位于底座本体211的Z轴正方的一表面,该顶面也称为第二组件200的安装面S3,当第一组件100安装于第二组件200时,该安装面S3与第一组件100相对)一侧,再对与底座本体211固定好的上述多个金属构件310植球,使主体部311远离第一弯折部312的一端形成焊球320。再结合图7,将安装底座210放置于电路板220的顶面(Z轴正方向上的表面),使E2区域与E3区域相对,F2区域与F3区域相对,G2区域与G3区域相对,H2区域与H3区域相对。以E2区域和E3区域为例,E2区域中的多个端子固定腔212与E3区域中的多个第二焊盘222一一相对,使每个端子300中的焊球320与E3区域中对应的第二焊盘222接触(图4b),再利用热处理等手段使焊球320与对应的第二焊盘222固定连接,其他区域中的端子300设置方式参考区域E2中的端子300的设置方式。定义每个端子300的第一弯折部312在第二组件200的安装面S3的上的正投影的延伸方向为该端子300的第一弯折部312的延伸方向(用R表示),其中,每个端子300的第一弯折部312的延伸方向R所在直线均平行于第一预设方向Q(示例性地,第一预设方向Q为X轴负方向)所在直线,也就是延伸方向R与第一预设方向Q相同或者相反,图9表示出了图6中E’区域中的端子固定腔212对应的多个端子300的俯视图的放大图,以图9为例,每个端子300的第一弯折部312的延伸方向R均与第一预设方向Q相反。接下来,将安装有芯片110的封装基板120安装于安装底座210,首先,需要将基板本体121的一端放入限位挡板(213e、213f、213g和213h)形成的槽状空间内,再沿着第一预设方向Q推动基板本体121,直至基板本体121的端部触碰到限位挡板213g和限位挡板213f时,将基板本体121下放至其底面与底座本体211的顶面平行,此时,基板本体121的四个角部与限位挡板(213e、213f、213g和213h)一一接触并被限位(参考图10),定位凸块214a配合于定位凹陷123a,定位凸块214b配合于定位凹陷123b,实现对基板本体121和安装底座210的定位连接,其中,由于定位凸块(214a和214b)是设置在底座本体211对应侧边的中间位置,相对于设置在对应侧边的边缘位置,每组端子固定腔212距离对应的定位凸块(214a和214b)距离更近,有利于减小端子300与第一焊盘122对位的累积误 差,实现每个端子300的第一弯折部312与对应第一焊盘122的精准对位(参考图10)。示例性地,每个定位凸块(214a和214b)的横截面呈半圆形,在具体制作安装底座210时,可以以凸块(214a和214b)的横截面的圆心为基准,确定每个端子固定腔212的精确位置,提高端子固定腔212的位置精准度,并且,为了避免封装基板120与安装底座210反装,可以将定位凸块(214a和214b)的外径设置为一大一小,而且,也可以在底座本体211的两组相对的侧边的中间位置均设置定位凸块,基板本体121上定位凹陷作类似设置;此时,第一组件100所处位置称为第一设定位置,并且被限位挡板(213e、213f、213g和213h)和定位凸块(214a和214b)锁定在该第一设定位置,且E1区域与E2区域相对,F1区域与F2区域相对,G1区域与G2区域相对,H1区域与H2区域相对。以E1区域和E2区域为例,E2区域中的多个端子固定腔212与E3区域中的多个第一焊盘122一一相对,使每个端子300中的焊球320与E2区域中对应的第一焊盘122接触(图4b),每个端子300使一对相对的第一焊盘122和第二焊盘222实现电连接。在一些情况下,第一焊盘122、第二焊盘222和端子固定腔212一一对应,即当第一模块100和第二模块如图4a所示的形式组装好后,每个端子固定腔212中的端子300分别与第一焊盘122和第二焊盘222一一对应连接。
在上述过程中,当沿着第一预设方向Q推动基板本体121时,基板本体121由于与暴露于底座本体211的顶面一侧的第一弯折部312直接接触,在基板本体121沿第一预设方向Q移动的过程中,基板本体121会给与其接触的第一弯折部312沿第一预设方向Q的摩擦力,而由于每个端子300的第一弯折部312的延伸方向R与第一预设方向Q相同或者相反,则每个端子300的第一弯折部312所受到的来自基板本体121的摩擦力的力臂为零,第一弯折部312所受到的力矩为零,所以第一弯折部312不易绕主体部311转动,因此,不同的端子300的第一弯折部312之间的距离不易发生改变,继续以图9为例,图9中,标注P的端子300为P信号端子,标注N的端子300为N信号端子,标注为G的为接地端子,由图9可知,一个P/N端子对中的P信号端子和N信号端子之间的间隙不易发生变化,从而,P信号端子和N信号端子组成的端子对阻抗不易发生变化;并且,可以知晓的是,不同P/N端子对中的信号端子(P信号端子和N信号端子)之间的间隙也不易变化,从而,减少了不同P/N端子对之间的串扰;此外,继续以图9为例,在一个P/N端子对中,沿着P信号端子和N信号端子的排列方向,P信号端子到相邻的接地端子的距离D1与P信号端子到相邻的接地端子的距离D2相等或者相近,如图9中具有4条等间隔设置的行标准线(L1、L2、L3和L4),每个端子300(如P信号端子)中心线相对于对应的行标准线(如L3)的偏移量d1小于或等于d2,其中,d2取P信号端子与N信号端子分别对应的第一焊盘122的中心线之间的距离、P信号端子与相邻的接地端子分别对应的第一焊盘122的中心线之间的距离,以及,N信号端子与相邻的接地端子分别对应的第一焊盘122的中心线之间的距离中的最小值的0.2倍;即便以较高的速度在第一组件100和电路板220之间通过端子300传输数据,信号也不容易失真,电子模块的SI性能得到提高。
需要说明的是,以上,每个端子300的第一弯折部312的延伸方向R所在直线平行于第一预设方向Q所在直线,仅仅是示例性的说明,只要满足如下条件,同一个端子300中的第一弯折部312就不容易相对于对应的主体部311旋转:基板本体121施加给第一弯折部312的摩擦力所产生的力矩,使第一弯折部312施加给主体部311的扭矩小于或等于主体部311因自身材料应力(主体部311多具有一定弹性)所产生的扭矩,主体部311不容 易绕自身轴线发生扭曲变形;也可以换句话说,基板本体121施加给第一弯折部312的摩擦力所产生的力矩小于或等于主体部311施加给第一弯折部312的扭矩;从而,第一弯折部312不容易绕第一主体部311的轴线发生旋转。
例如,当金属构件310的材质为铜合金和磷青铜等常用材质时,使每个端子300的第一弯折部312的延伸方向R所在直线与第一预设方向Q所在直线之间的夹角介于0°至15°之间,示例性地,该夹角可以是0°、2°、5°、7°、8°、10°、11°、13°或者15°;此时,由于基板本体121施加给第一弯折部312的摩擦力所对应的力臂很小,基板本体121施加给第一弯折部312的摩擦力所产生的力矩较小,不足以使第一弯折部312施加给主体部311的扭矩克服主体部311因自身材料应力所产生的扭矩,第一弯折部312也就不容易相对于主体部311旋转。
图4c表示出了图4a中B处的局部放大图,请结合图4a、图4b、图4c和图6,图4b中的3个端子300依次对应于图6中H2区域沿Y轴正方向上的第一排的三个端子固定腔212,图4c中的3个端子300依次对应于图6中G2区域沿Y轴正方向上的第一排的三个端子固定腔212,图4b中3个端子300的第一弯折部312的延伸方向R与图4c中3个端子300的第一弯折部312的延伸方向R一致,其他每一行端子300也可以参照图4b和图4c中的端子300的形式设置。
与上述形式形成对比的,图11a表示出了图4a所示的电子模块的一种变形,图11a相对于图4a的区别在于,A’处(对应于图4a中的A处)的3个端子300的第一弯折部312与B’处(对应于图4a中B处)的3个端子300的第一弯折部312相向设置,示例性地,A’处的3个端子300的第一弯折部312的延伸方向R与B’处的3个端子300的第一弯折部312的延伸方向R在同一条直线上且方向相反;当封装基板120安装在安装底座210中时,每个端子300的金属构件310都会被第一焊盘122压缩变形,具体地,对于每个端子300,第一弯折部312沿自身延伸方向R滑动,主体部311沿与第一弯折部312的延伸方向R相反的方向拱起,由于主体部311和第一弯折部312自身材料弹性,第一弯折部312会给对应的第一焊盘122一个与该第一弯折部312延伸方向R相反的摩擦力;而由于A’处的3个端子300与B’处的3个端子300位于同一行上,且A’和B’两处中端子300的第一弯折部312的延伸方向R方向相反,A’和B’两处中端子300的第一弯折部312分别施加给对应的第一焊盘122方向相反的摩擦力,使封装基板210整体受到的A’和B’两处中端子300的摩擦力相互抵消,有利于保持封装基板210的受力平衡,其中的每个第一焊盘122不易与对应端子300错位,而其他行的端子300也可以参考A’和B’两处中端子300的形式设置。
图11b表示出了图4a所示的电子模块的另一种变形,图11b与图11a的区别在于,A”处(对应于图4a中的A处)的3个端子300的第一弯折部312与B”处(对应于图4a中B处)的3个端子300的第一弯折部312相背设置,示例性地,A”处的3个端子300的第一弯折部312的延伸方向R与B”处的3个端子300的第一弯折部312的延伸方向R在同一条直线上且方向相反;从而,与图11a中的电子模块类似的,封装基板210整体受到的A”和B”两处中端子300的摩擦力相互抵消,保持封装基板210受力平衡。
应当说明的是,在图11a中,A’处的3个端子300的第一弯折部312与B’处的3个端子300的第一弯折部312相向设置,也可以是A’处的3个端子300的第一弯折部312的延伸方向R所在直线和B’处的3个端子300的第一弯折部312的延伸方向R所在直线 均与第一预设方向P所在直线形成一定夹角(如可以5°、10°和15°等角度中的任意一个夹角度数);这样,A’处的端子300的第一弯折部312施加给封装基板210的摩擦力和B’处的端子300的第一弯折部312施加给封装基板210的摩擦力分别在X轴方向上的分力方向相反且至少部分相互抵消,也有利于保持封装基板210的受力平衡。图11b中的各行端子300也可以做类似设置。
无论是在图11a的中A’处和B’处,还是图11b中A”处和B”处,在同一行端子300中,并且,在每一行端子300中,当第一弯折部312朝向第一预设方向Q的端子300的数量等于第一弯折部312的背离第一预设方向Q的端子300的数量时,有利于同一行端子施加给封装基板210的摩擦力充分抵消,甚至完全抵消;此外,第一弯折部312的朝向第一预设方向Q的端子300连续设置(如,图11a中的B’处的端子300和图11b处中的A’处端子300),第一弯折部312的背离第一预设方向Q的端子300也连续设置(如,图11a中的A’处的端子300和图11b处中的B’处端子300),这仅仅是示例性的设置形式,这样,对于同一行端子300,有利于当第一焊盘122间隔均匀的情况下,保持第一弯折部312的延伸方向R相同的端子300的主体部311之间以及第一弯折部312的间隙均匀,从而,有利于避免同一P/N端子对的阻抗加大,或者不同P/N端子对的串扰加大,进一步提升电子模块的SI性能。但,应当理解的是,当第一弯折部312的朝向不同的端子300间隔设置时,也可以在一定程度上达到使封装基板210受力平衡的作用。
图12表示出了图4a所示的电子模块的另一种变形,A”’处对应于图4a中的A处,图12中的电子模块与图4a中的电子模块的区别在于,每个端子300中的焊球320替换为第二弯折部313,每个端子300所包括的第一弯折部312、第二弯折部313和主体部311可以是一体成型的金属构件;与第一弯折部312类似地,定义每个端子300的第二弯折部313在第二组件200的安装面S3的上的正投影的延伸方向为该端子300的第二弯折部313的延伸方向(用V表示);在将安装底座210装配于电路板220时,通常情况下,需要推动底座本体211沿着第二预设方向W相对于电路板本体221滑动一定距离(如在电路板本体221上设置沿第二预设方向W延伸的限位壁,底座本体211沿着该限位壁滑动,底座本体211与电路板本体221滑动配合的结构形式可以是本领域已知的常用的现有技术,在此不再赘述),再将底座本体211相对于电路板本体221锁定(可以是卡接)在第二设定位置;示例性地,使每个第二弯折部313的延伸方向V所在直线平行于第二预设方向W所在直线,也就是第二弯折部313的延伸方向V与第二预设方向W相同或者相反,此时,在推动底座本体211沿着第二预设方向W相对于电路板本体221运动时,电路板本体221施加给第二弯折部313的摩擦力的力臂为零,因此,该摩擦力的力矩不足以使第二弯折部313相对于主体部311发生旋转;总之,通过使用刚性较好的材料制作端子300,或者,使端子300中第二弯折部313的延伸方向V满足一定要求等方式,使基板本体121施加给第二弯折部313的摩擦力所产生的力矩小于或等于主体部311施加给第二弯折部313的扭矩,第二弯折部313就不易相对于主体部311旋转;例如,例如,当端子300的材质为铜合金和磷青铜等常用材料时,使每个端子300的第二弯折部313的延伸方向V所在直线与第二预设方向W所在直线之间的夹角介于0°至15°之间,如,该夹角可以是0°、2°、5°、7°、8°、10°、11°、13°或者15°,此时,第二弯折部313不容易相对于主体部311旋转;从而,提升电子模块的SI性能。
在一个具体的实施例中,可以使每个端子300中第一弯折部312的延伸方向R与第二 弯折部313的延伸方向V相反,如当第一预设方向Q和第二预设方向P方向相反时,第一弯折部312的挤压变形方向与第二弯折部313的挤压变形方向相反,第一弯折部312和第二弯折部313所受到的反向摩擦力方向相反,有利于该端子300的受力平衡。
图13表示出了本申请实施例提供的电子模块中端子300的排列方式与电路板220中走线(如223a和223b)的位置关系图,请参考图13,多个端子300阵列分布于电路板220表面,其中,以走线223a为例,一对P信号端子和N信号端子分别与电路板本体221上的走线223a电连接,走线223a先沿着X轴正方向延伸,且在沿X轴方向延伸的过程中,其平行于两侧的端子的排列方向(如图13中的3行第1列的P信号端子与该P信号端子X轴正方向上的接地端子的排列方向),接着走线223a沿着Y轴正方向延伸,且在沿着Y轴延伸的过程中,其平行于两侧的端子的排列方向(如图13中第3行和第4行中的第2列的两个接地端子的排列方向),并且,两个走线223a整体始终沿着其两侧的端子的中间位置延伸,有利于避免走线223a离其中一侧的端子300过近,影响该端子300的性能,进而,提升电子模块的SI性能。其中,走线也可以只沿着一个方向扇出,如走线223b。
需要说明的是,以上第一组件100不限于芯片110与封装基板120的组合形式,如第一组件也可以是寄生电路板通过端子300与第二组件200中的电路板220配合;此外,第二组件200也并不局限于电路板220与安装底座210的组合形式,也可以是其他具有用来传输信号的焊盘(类似于第二焊盘222)的结构。
基于相同的发明构思,本申请实施例还提供了一种电子设备,该电子设备可以是计算机、手机和服务器等,该电子设备包括存储模块和上述实施例提供的电子模块,其中,存储模块与电子模块中的第一组件电连接(该“电连接”可以是直接连接,也可以是间接连接);示例性地,请结合图4a至图13,通过设置该电子模块,由于在第一组件100沿第一预设方向Q相对于第二组件200滑动时,第一组件100施加给每个端子300的第一弯折部312的摩擦力的力矩小于或等于主体部311施加给第一弯折部312的扭矩,第一弯折部312不容易相对于对应的主体部311旋转,提升电子模块的SI性能,从而,提升电子设备的性能。此外,芯片110为CPU时,该CPU与存储模块电连接,可读取存储模块中的数据或者向存储模块中写入数据。
