图1为封装结构内的零件提取方法的流程示意图,下面参考图1-图10描述根据本公开实施例的封装结构11内的零件12提取方法,包括以下步骤:
在研磨治具10中放入粘合剂,并将粘合剂软化;如此一来,软化后的粘合剂能有较高的融合性能,能够让封装结构11放置到软化的粘合剂上,从而能够是实现对封装结构11的处理。
将封装结构11放入粘合剂中且使封装结构11封装有电路板的一面朝上,并将粘合剂固化;这样,将封装结构11上设有电路板的一面朝上,能够便于后续对封装结构11的零件12提取。而将粘合剂固化后能够让封装结构11在研磨治具10的设置更为稳定,从而能够便有对封装结构11上的零件12提取。
研磨封装结构11,直至露出零件12;需要说明的是,研磨去除封装结构11上的封装层,以让封装结构11上的零件12露出,从而便于零件从封装结构内的取出。
将粘合剂软化,取出零件12。而将粘合剂软化后,不仅可以实现零件12的取出,还能取出已经去除零件12的封装结构11,从而让另一个封装结构11放置到粘合剂上以实现重复使用,降低封装结构11的取出成本。
也就是说,在取出实现取出封装结构11内的零件12时,适于将封装结构11通过粘合剂设置在研磨治具10上之后对封装结构11进行研磨,让封装结构11上封装在所需零件12外侧的结构适于得到取出,包括封装在零件12外侧的封装材料以及设置在零件12外侧电路板,从而能够将封装结构11内的零件12的取出以实现对零件12的回收。
根据本公开实施例的封装结构11内的零件12提取方法,通过将封装结构11装设到研磨治具10上并对其进行研磨,以使零件露出从而实现封装结构11内零件12取出,从而让封装结构11上的零件12能够进行回收利用。
在一些实施例中,如图2所示,图2为研磨封装结构直至露出零件步骤的流程示意图,在研磨封装结构11,直至露出零件12的步骤包括:将粘合剂软化,取出封装结构11;如此一来,能够实现对粘合剂的重复使用,取出封装结构11后可以放置新的封装结构11进行零件 12的取出,也可以用于取出封装结构11的另一面的零件12。
将封装结构11放入粘合剂中且使封装结构11的封装结构11背离电路板的一侧朝上,并将粘合剂固化;这样,能够对封装结构11的另一面的零件12进行取出,从而提升封装结构11内的零件12取出的提取效率。
再次研磨去除封装结构11中的封装材料13,直至露出零件12;可以理解的是,与上述研磨取出电路板的方式相同,都是通过研磨去除封装材料13,并将零件12露出,以便于零件12提取。
如此一来,通过采用上述方式研磨封装结构11,能够将封装结构11上影响零件12取出的结构得以去除,从而让零件12的取出更为可靠。
在一些实施例中,如图3所示,图3为研磨治具中放入粘合剂并将粘合剂软化步骤的流程示意图,研磨治具10中设置有凹槽100;可以理解的是,凹槽100适于为封装结构11的组装提供位置,以使封装结构11能够更为可靠的装设到研磨治具10上进行零件12的提取。在研磨治具10中放入粘合剂,并将粘合剂软化的步骤包括:
在凹槽100内放入粘合剂;如此一来,能够更为合理的利用粘合剂,避免粘合剂的浪费。
将粘合剂加热至熔融状态。熔融状态的粘合剂能够便于封装结构11的放置,从而让封装结构11在研磨治具10上的放置更为稳定可靠,使得零件12从封装结构11上的提取更为简单方便。
这样,通过将凹槽100内设有粘合剂并对其进行加热软化,以使封装结构11能够更为可靠的设置在研磨治具10上,以便于对封装结构11的提取处理,从而让封装结构11的零件12提取过程更为高效。
在一些具体的实施例中,将放有粘合剂的研磨治具10放入加热设备中,加热温度T1满足关系式:90℃≤T1≤110℃,例如T1=90℃、T1=93℃、T1=95℃、T1=98℃、T1=100℃、T1=102℃、T1=105℃、 T1=107℃或T1=110℃等。不仅能够实现将粘合剂变成熔融状态,而且能够避免加热过程中对于封装结构11的影响,从而让封装结构11能够实现零件12提取。
在一些实施例中,如图4所示,图4为将封装结构放入粘合剂中且使得封装结构封装电路板的一面朝上并将粘合剂固化步骤的流程示意图,将封装结构11放入粘合剂中且使得封装结构11封装电路板的一面朝上,并将粘合剂固化的步骤包括:
将封装结构11放入粘合剂中且使得封装结构11封装电路板的一面朝上;这样,能够便于封装结构11封装有电路板的一面的研磨处理,以让封装结构11上的零件12提取更为简单可靠。
对封装结构11施加压力,使封装结构11封装电路板的一面与研磨治具10的表面处于同一水平面上。如此一来,能够便于对研磨治具10的使用,以实现封装结构11上电路板的露出与取出。
由此,采用施加压力的方式将封装结构11以平齐的方式设置在研磨治具10上,以便于对封装结构11进行研磨,从而能够实现对封装结构11内零件12的提取。
在一些实施例中,如图5所示,图5为研磨封装结构直至取出电路板步骤的流程示意图,研磨封装结构11,直至取出电路板的步骤包括:
研磨封装结构11,直至露出零件12和电路板之间的焊接点,且研磨后的平面光整度不低于预定值。这样,将焊接点露出后,能够通过去除焊接点实现电路板的取出。
如此一来,通过对封装结构11进行研磨,让零件12与电路板之间的焊接点得以露出,从而让零件12在封装结构11上的设置得以松动,以能够完成将封装结构11内的零件12的提取。
在一些实施例中,将粘合剂软化,取出封装结构11的步骤包括:
将粘合剂加热至熔融状态;可以理解的是,将粘合剂再次加热到 熔融状态,不仅便于封装结构11的取出,而且能够便于零件12从封装结构11上的取出;
取出封装结构11;去除封装结构11表面粘附的粘合剂。这样,通过去除封装结构11表面的粘合剂,能够便于封装结构11上的零件12取出。且去除的粘合剂能够进行重复使用,降低封装结构11内的零件12提取方法的使用成本。
可以理解的是,粘合剂在研磨过程中并不会得到损耗,因此可以对粘合剂进行回收利用,以降低封装结构11的在进行零件提取时的运行成本。
在一些实施例中,如图6所示,图6为将封装结构放入粘合剂中且使封装结构背离电路板的一侧朝上并将粘合剂固化步骤的流程示意图,将封装结构11放入粘合剂中且使封装结构11背离电路板的一侧朝上,并将粘合剂固化的步骤包括:将封装结构11封装有电路板的一面朝向粘合剂并放入粘合剂中;对封装结构施加压力,直至封装结构11的未封装有电路板的与研磨治具10的表面处于同一水平面上。如此一来,不仅可以让封装结构11上的电路板的提取更为简单方便,便于封装结构11上的零件12取出,而且还能将封装结构11的另一面的零件12进行取出,以提升封装结构11内零件12的取出数量,提升零件12的回收利用效率。
在一些实施例中,如图7所示,图7为研磨去除封装结构中的封装材料以露出零件步骤的流程示意图,研磨去除封装结构11中的封装材料13,露出零件12的步骤包括:研磨去除封装结构11中的封装材料13,直至露出零件12的表面;抛光零件12的表面,直至露出零件12表面的标识信息。这样,通过研磨与抛光零件12的表面,能够露出零件12的标识信息,可以通过对零件12标识信息的区分实现不同零件12的回收处理,从而便于多个封装结构11进行零件12取出后的回收利用。
在一些实施例中,如图8所示,图8为将粘合剂软化以取出零件 步骤的流程示意图,将粘合剂软化,取出零件12的步骤包括:将粘合剂再次加热至熔融状态;这样,将粘合剂再次加热,能够便于取出零件12;采用去胶液去除零件12表面的粘合剂。而采用去胶液能够更为高效的取出零件12表面的粘合剂,从而便于零件12的取出,提升封装结构11内的零件12提取方法的使用效率。
在一些实施例中,如图9所示,图9示出了封装结构内的零件提取方法在将粘合剂软化以取出零件的步骤之后,还包括采用研磨或激光切割的方式去除零件边缘残留的封装材料的流程示意图,将粘合剂软化,取出零件12的步骤之后,还包括以下步骤:采用研磨或激光切割的方式去除零件12边缘残留的封装材料13。由此,采用激光切割的方式,能够更为高效的去除零件12边缘的封装材料13,从而让零件12的提取效果更好,以提升零件12的回收利用效率。
如图10所示,图10为研磨治具的结构示意图,根据本公开实施例的应用于上述封装结构11内的零件12提取方法的研磨治具10,研磨治具10的至少一侧表面设置有凹槽100,凹槽100用于容置粘合剂和封装结构11。这样,通过将封装结构11内的零件12提取方法应用于研磨治具10,通过将封装结构11装设到研磨治具10上并去除封装材料13,以实现封装结构11上的零件12取出,从而让封装结构11上的零件12能够进行回收利用。同时,还能将粘合剂进行多次软化,以降低封装结构11内的零件12提取方法的使用成本。
