综上所述,本申请实施例提供的同一电路板31可以兼容第一存储芯片和第二存储芯片。
在一些可能的实现方式中,针对第一类焊盘311中的第一类引脚共用焊盘3111,其用于与第一存储芯片的电源引脚和第二存储芯片的电源引脚连接。在电路板31上装配第一存储芯片或第二存储芯片时,若第一类引脚共用焊盘3111对应连接的处理器芯片33的电源引脚为同一电源引脚,这种情况下,可以将两路走线合并为一路走线。
图31为本申请实施例提供的第六类焊盘与第三走线的一种连接关系示意图,图32为本申请实施例提供的第六类焊盘与第三走线的另一种连接关系示意图。参照图31和图32所示,电路板31还包括第二焊盘组,第二焊盘组用于与处理器芯片33连接,电路板31还用于承载第三电源模块343。多个第二焊盘包括第六类焊盘51,第六类焊盘51用于与第一存储芯片的电源引脚和第二存储芯片的电源引脚连接;在电路板31用于承载第一存储芯片的情况下,第一存储芯片的电源引脚依次通过第六类焊盘51、第三走线43和第三电源模块343与处理器芯片33的第一电源引脚连接;在电路板31用于承载第二存储芯片的情况下,第二存储芯片的电源引脚依次通过第六类焊盘51、第三走线43和第三电源模块343与处理器芯片33的第二电源引脚连接;第一电源引脚和第二电源引脚为同一电源引脚。
一种方式,如图31所示,第六类焊盘51连接的第三走线43包括第二跳选区域317;在电路板31用于承载第一存储芯片或第二存储芯片的情况下,第六类焊盘51连接的第三走线43包括的第二跳选区域317用于装配跳选元件。
另一种方式,如图32所示,第六类焊盘51连接的第三走线43不包括第二跳选区域317;在电路板31用于承载第一存储芯片或第二存储芯片的情况下,第三电源模块343用于对第六类焊盘51连接的第三走线43进行上电。并且,在电路板31上装配第一存储芯片时第三电源模块343上电所输出的电压,与在电路板31上装配第二存储芯片时第三电源模块343上电所输出的电压可能不同。
在一些实施例中,第一存储芯片的尺寸与第二存储芯片的尺寸一致。
在一些实施例中,目标存储芯片32和处理器芯片33可以位于电路板31的第一表面。在电路板31上装配第一存储芯片或第二存储芯片时,第一跳选区域316处装配的跳选元件可以位于电路板31的第二表面,第二表面和第一表面可以为电路板中相对设置的两个表面。
这样,针对同一个焊盘所连接的两路走线,可以将第一跳选区域316处装配的跳选元件,与目标存储芯片32和处理器芯片33分布在电路板31的两侧,以减少两路走线造成的信号匹配问题。
在另一些实施例中,目标存储芯片32、处理器芯片33和第一跳选区域316处装配的跳选元件也可以位于电路板31的同一表面上,且第一跳选区域316与目标存储芯片32之间的距离,小于第一跳选区域316与处理器芯片33之间的距离。
这样,针对同一个焊盘所连接的两路走线,其包括的第一跳选区域316可以尽量靠近目标存储芯片32所在的位置,使得在第一跳选区域316处装配电阻等跳选元件后,可以减少两路走线造成的信号匹配问题。
在一些实施例中,针对信号线兼容的场景,如图16所示的场景,两路走线在分叉前的走线宽度与分叉后的走线宽度之间的差值小于预设值,预设值可以为0或者趋于0的数值,使得两路走线在分叉前的走线宽度与分叉后的走线宽度基本保持一致。这样,可以调整两路走线传输的信号的阻抗。
以上描述主要针对的是在同一电路板31上兼容第一存储芯片和第二存储芯片的实现方式。当然,本申请实施例中的电路板31还可以兼容三种或三种以上类型的存储芯片。
具体的,电路板31用于承载目标存储芯片32,目标存储芯片32包括至少两种存储芯片中的任意一种存储芯片,至少两种存储芯片中的各种存储芯片的引脚数量均相等,且至少两种存储芯片中的各种存储芯片的引脚排布均相同。电路板31包括第一焊盘组,第一焊盘组用于与目标存储芯片32连接;第一焊盘组包括多个第一焊盘,每个第一焊盘均与至少两路走线连接,至少部分的第一焊盘连接的每一路走线均包括第一跳选区域316,第一跳选区域316处的走线断开设置。在电路板31用于承载目标存储芯片32的情况下,至少部分的第一焊盘连接的目标走线包括的第一跳选区域316用于装配跳选元件,目标走线为第一焊盘连接的至少两路走线中与目标存储芯片32对应的一路走线。
在一些实施例中,第一焊盘组包括的各个焊盘与目标存储芯片32包括的各个引脚一一对应。具体的,第一焊盘组包括各个焊盘的排布阵列与目标存储芯片32包括的各个引脚的排布阵列相同,且第一焊盘组包括的焊盘数量与目标存储芯片32包括的引脚数量相等。
在一些实施例中,至少两种存储芯片中的各种存储芯片的尺寸均相同。
因此,本申请实施例中的同一电路板31可以兼容至少两种存储芯片。并且,同一电路板31兼容的至少两种存储芯片包括但不限于第一UFS存储芯片、第二UFS存储芯片以及EMMC存储芯片中的至少两者。
以上的具体实施方式,对本申请的目的、技术方案和有益效果进行了进一步详细说明,所应理解的是,以上仅为本申请的具体实施方式而已,并不用于限定本申请的保护范围,凡在本申请的技术方案的基础之上,所做的任何修改、等同替换、改进等,均应包括在本申请的保护范围之内。
