在图中,结构相似的单元是以相同标号表示。
如图2和图3所示,本申请公开一种阵列基板的测试设备。包括:机台10,用于放置多个待测试的阵列基板11;测试接口20,设置在机台10上,与每个阵列基板11对应;测试器21,设置在机台10上,与测试接口20配合,所述测试器21的长度尺寸大于或等于其测试区域的宽度尺寸,对阵列基板11进行电应力测试和加电测试;测试器21至少有两组,根据预设方案同步运行。
测试设备有至少两组测试器21,相对于只采用单个测试器21,单个测试器21测试时先做电应力测试,然后再做加电测试,整个测试过程中,测试器21每次移动到测试接口20位置都需要先做电应力测试,然后再做加电测试,测试时间等于电应力测试时间与加电测试时间之和,这样相对浪费了其它组测试器21,没有有效到所有测试器21,因此,本申请通过采用至少两组测试器21一同工作,这样既有效利用了测试器21,又可以节省测试时间,有效节省了工序节拍。
本实施例可选的,测试器21包括第一测试器30和第二测试器31,沿测试方向,第一测试器30位于第二测试器31前方,预设方案包括:第一测试器30进行电应力测试,第二测试器31进行加电测试。
相对于利用单组测试器21工作来说,利用两组测试器21会使单位时间测试量翻倍,使工作效率加快,本案通过设置将第一测试器30用于电应力测试,而第二测试器31用于加电测试,这样分工合作,既可以使得工作有序,还可以提高测试器21的工作效率,并且避免了每组测试器21经常转换模式带来的损耗。
本实施例可选的,所述测试器的长度大于或等于机台的测试区域的宽度,第二测试器31开始工作时先做电应力测试而后再做加电测试,之后第二测试器31对第一测试器30测试后的测试接口20只进行加电测试。
由于两组测试器21可以一起动作,但不能提前做电应力测试,因此,本案使第二测试器31开始工作时既做电应力测试又做加电测试,第一测试器30只做电应力测试,之后第二测试器31对第一测试器30测试后的测试接口20只进行加电测试,这样就相当于整个测试中的电应力测试30只耗费了一次的电应力时间,节省了测试工序的时间,并且相对单组测试器21,本案提高了测试效率。
本实施例可选的,预设方案包括:将测试接口20平均分成至少两组,每组测试器21对应测试一组测试接口20。
测试器21对产品测试过程其实是双向的,产品对测试器21也是有一个反馈的过程,假设测试器21故障,对任何测试接口20的测试都无变化,那么在产品使用后出现问题,这时根据 产品的问题测试接口20可以对应找到故障测试器21,因此本案将测试接口20平均分成至少两组,每组测试器21对应测试一组测试接口20,这样既可以提高测试器21的利用率,还可以达到测试纪录可追溯的效果。
如图4中所示,本实施例可选的,测试器21包括第一测试器30和第二测试器31,预设方案包括:将第一测试器30和第二测试器31初始位置设置在机台10两端,相应的,以机台10中间为界,将测试接口20平均分成两组,测试时,第一测试器30和第二测试器31以运动方向相对移动。
每个测试器21只需移动机台10一半长度的距离,即可完成所有阵列基板11的测试,移动距离比较小,提高测试效率,同时也可以实现产品与测试器21的双向反馈。
本实施例可选的,测试器21包括第一测试器30和第二测试器31,预设方案包括:将第一测试器30和第二测试器31初始位置设置在机台10同一端,相应的,根据奇数行和偶数行的规则,将测试接口20平均分成两组,测试时,第一测试器30和第二测试器31同步从机台10的一端往另一端移动。
两组测试器21同时工作时,测试每个测试接口20的时间基本相同,因此,实际两组测试器21更换下一个测试接口20位置应该是同步的,那么将第一测试器30和第二测试器31初始位置设置在同一端,相应的,根据奇数行和偶数行的规则,将测试接口20平均分成两组,测试时,第一测试器30和第二测试器 31同步从机台10的一端往另一端移动,使得两组测试器21始终保持挨着,这样方便操作,相对节省更换测试接口20位置的时间,提高工作效率,而且还可以实现产品与测试器21的双向反馈。
本实施例可选的,每个阵列基板11对应两个测试接口20。
作为本申请的另一实施例,如图2和图3所示,本申请还公开了一种阵列基板的测试设备的测试方法。一种阵列基板11的测试设备包括:机台10,用于放置多个待测试的阵列基板11;测试接口20,设置在机台10上,与每个阵列基板11对应;测试方法包括:在机台10上设置至少两组测试器21;将测试器21连接到测试接口20;根据预设方案同步运行测试器21,对阵列基板11进行电应力测试和加电测试。
测试设备有至少两组测试器21,相对于只采用单个测试器21,单个测试器21测试时先做电应力测试,然后再做加电测试,整个测试过程中,测试器21每次移动到测试接口20位置都需要先做电应力测试,然后再做加电测试,测试时间等于电应力测试时间与加电测试时间之和,这样相对浪费了其它组测试器21,没有有效到所有测试器21,因此,本申请通过采用至少两组测试器21一同工作,这样既有效利用了测试器21,又可以节省测试时间,有效节省了工序节拍。
本实施例可选的,测试器21包括第一测试器30和第二测 试器31,沿测试方向,第一测试器30位于第二测试器31前方,预设方案包括:第一测试器30进行电应力测试,第二测试器31进行加电测试。
由于电应力测试所耗时长短于加电测试所耗时长,那么设第一测试器30进行电应力测试,第二测试器31进行加电测试,这样第一测试器30相对第二测试器31来说“跑”得更快,所以测试时两测试器21各不干涉,而且对于整个测试过程来说,在电应力测试上相当于只花费了一个测试接口20的电应力测试时间,从而节省了测试工序的时间。
本实施例可选的,测试器21的长度大于或等于机台10的测试区域的宽度,第二测试器31开始工作时先做电应力测试,而后再做加电测试,之后第二测试器31对第一测试器30测试后的测试接口20只进行加电测试。
考虑到测试器21需要对机台10的测试区域进行测试,那么就要满足测试器21的长度大于或等于机台10的测试区域的宽度,否则容易出现漏测位置;第二测试器31与第一测试器30配合工作,两测试器一起开始测试,第一测试器30只负责电应力测试,而第二测试器31开始时完成电应力测试和加电测试,之后只负责对第一测试器30做完电应力测试后的测试接口20进行加电测试,这样可以节省电应力测试的时间,提高测试效率。
本实施例可选的,预设方案包括:将测试接口20平均分成至少两组,每组测试器21对应测试一组测试接口20。
测试器21对产品测试过程其实是双向的,产品对测试器21也是有一个反馈的过程,假设测试器21故障,对任何测试接口20的测试都无变化,那么在产品使用后出现问题,这时根据产品的问题测试接口20可以对应找到故障测试器21,因此本案将测试接口20平均分成至少两组,每组测试器21对应测试一组测试接口20,这样既可以提高测试器21的利用率,还可以达到测试纪录可追溯的效果。
本实施例可选的,测试器21包括第一测试器30和第二测试器31,预设方案包括:将第一测试器30和第二测试器31初始位置设置在机台10两端,相应的,以机台10中间为界,将测试接口20平均分成两组,测试时,第一测试器30和第二测试器31以运动方向相对移动。
每个测试器21只需移动机台10一半长度的距离,即可完成所有阵列基板11的测试,移动距离比较小,提高测试效率,同时也可以实现产品与测试器21的双向反馈。
本实施例可选的,测试器21包括第一测试器30和第二测试器31,预设方案包括:将第一测试器30和第二测试器31初始位置设置在机台10同一端,相应的,根据奇数行和偶数行的规则,将测试接口20平均分成两组,测试时,第一测试器30和第二测试器31同步从机台10的一端往另一端移动。
两组测试器21同时工作时,测试每个测试接口20的时间基本相同,因此,实际两组测试器21更换下一个测试接口20位 置应该是同步的,那么将第一测试器30和第二测试器31初始位置设置在同一端,相应的,根据奇数行和偶数行的规则,将测试接口20平均分成两组,测试时,第一测试器30和第二测试器31同步从机台10的一端往另一端移动,使得两组测试器21始终保持挨着,这样方便操作,相对节省更换测试接口20位置的时间,提高工作效率,而且还可以实现产品与测试器21的双向反馈。
本实施例可选的,测试器21包括第一测试器30和第二测试器31,沿测试方向,第一测试器30位于第二测试器31前方,第一测试器30与第二测试器31不同是开始工作。
相对一个测试器21工作来说,两个测试器21可以极大提高工作效率,若两个测试器21同时开始工作,那么意味着操作人员要同时操作两个测试器21,那么有带来操作困难导致测试工作出错的可能性,因此,本案使第一测试器30与第二测试器31不同是开始工作,这样操作人员就可以根据第一测试器30与第二测试器31工作时产生的时间差,对两组测试器21更好的操作,避免因繁忙导致纰漏,提高测试工作效率。
本实施例可选的,第一测试器30和第二测试器31同时放置在对应的测试接口20上,第一测试器30先于第二测试器31开始测试工作。
因为第一测试器30在第二测试器31之前,为了两组测试器21工作时互不干涉,因此,本案使第一测试器30先于第二测 试器31开始工作,这样既互不干扰,而且方便操作员操作,极大提高工作效率。
本实施例可选的,每个阵列基板对应两个测试接口。
本实施例可选的,预设方案包括如上任意所述的预设方案,均可以实现缩短测试时间,提升测试效率的效果。
作为本申请的另一实施例,如图2和图3所示,本申请还公开了一种阵列基板11的测试方法,所述阵列基板11包括测试设备:机台10,用于放置多个待测试的阵列基板11;测试接口20,设置在机台10上,与每个阵列基板11对应;测试方法包括:S61、在机台10上设置至少两组测试器21;S62、根据预设方案控制测试器21与测试接口20配合;S63、对阵列基板11进行电应力测试和加电测试。
在机台10上设置至少两组测试器21,相对于单组测试器21工作,通过同样的预设方案,那么至少两组测试器21可以完成单位时间内翻倍的工作量,提高了工作效率;同时,同一机台上可以同时安装至少两组测试器21,这样充分利用了测试器21,还节省了测试工序的时间。
需要说明的是,本方案中涉及到的各步骤的限定,在不影响具体方案实施的前提下,并不认定为对步骤先后顺序做出限定,写在前面的步骤可以是在先执行的,也可以是在后执行的,甚至也可以是同时执行的,只要能实施本方案,都应当视为属于本申请的保护范围。
以上内容是结合具体的可选的实施方式对本申请所作的进一步详细说明,不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说,在不脱离本申请构思的前提下,还可以做出若干简单推演或替换,都应当视为属于本申请的保护范围。
