Abstract

本发明提出了一种液晶显示玻璃绑定FPC的方法,所述液晶显示玻璃和FPC通过FOG绑定工艺连接,液晶显示玻璃上设有顺序排列的导入焊盘,FPC上设有输出焊盘,输出焊盘与导入焊盘一一对应,相邻导入焊盘之间的间距S1与相邻输出焊盘之间的间距S2相等,导入焊盘宽度W1为输出焊盘宽度W2的70%~80%。本发明中,由于输出焊盘的宽度大于导入焊盘的宽度,即使输出焊盘宽度及间距由于FPC膨胀而发生小幅度的扩大,这种变化对导入焊盘与输出焊盘FOG绑定的影响也不足以引起绑定偏移,从而可保证液晶显示玻璃绑定FPC的稳定可靠。

Description

一种液晶显示玻璃绑定FPC的方法
技术领域
本发明涉及引脚绑定技术领域,尤其涉及一种液晶显示玻璃绑定FPC的方法。
背景技术
现在市场上存在中小尺寸液晶显示模组由液晶显示玻璃、驱动IC、FPC(FlexiblePrinted Circuit,柔性印刷电路板)及背光单元组成,这类液晶显示模组广泛用于手机、平板、MP4、PDA等移动设备上。
现有的液晶显示玻璃与FPC是通过FOG Bonding(FPC On Glass Bonding,FPC玻璃键合)技术绑定,在一定的温度和压力的情况下,通过各向异性导电膜将液晶显示玻璃上的导入焊盘与FPC上的输出焊盘导通连接,如下图1。
但是由于FPC是以聚酰亚胺或聚酯薄膜等膨胀系数大的材料为基材制成的,在高温和大压力的情况FPC因材料的温度特性容易受热膨胀从而导致输出焊盘宽度及相邻输出焊盘之间的间距发生变化。
参照图2,现有技术中,导入焊盘的宽度为0.08mm大于输出焊盘的宽度0.06mm,相邻导入焊盘的间距与相邻输出焊盘的间距相等均为0.12mm。参照图3,当FPC膨胀,输出焊盘的宽度以及间距变大,从而导致液晶显示玻璃上的导入焊盘与输出焊盘无法准确对位,引起FOG绑定偏移,从而导致液晶显示玻璃无法稳定可靠的工作。
发明内容
基于背景技术存在的技术问题,本发明提出了一种液晶显示玻璃绑定FPC的方法克服现有技术的缺陷。
本发明提出的一种液晶显示玻璃绑定FPC的方法,所述液晶显示玻璃和FPC通过FOG绑定工艺连接,液晶显示玻璃上设有顺序排列的导入焊盘,FPC上设有输出焊盘,输出焊盘与导入焊盘一一对应,相邻导入焊盘之间的间距S1与相邻输出焊盘之间的间距S2相等,导入焊盘宽度W1为输出焊盘宽度W2的70%~80%。
优选地,相邻输出焊盘之间的间距S2与输出焊盘宽度W2成正比。
优选地,导入焊盘宽度W1为输出焊盘宽度W2的75%。
优选地,导入焊盘宽度W1=0.06mm,间距S1=0.12mm,输出焊盘宽度W2=0.08mm,间距S2=0.12mm。
优选地,导入焊盘长度L1与输出焊盘长度L2相等。
本发明通过拓宽输出焊盘宽度的方式降低FPC膨胀对输出焊盘宽度及间距的影响,从而克服现有技术中FPC膨胀后,液晶显示玻璃和FPC绑定偏移的问题。
本发明中,由于输出焊盘的宽度大于导入焊盘的宽度,即使输出焊盘宽度及间距由于FPC膨胀而发生小幅度的扩大,这种变化对导入焊盘与输出焊盘FOG绑定的影响也不足以引起绑定偏移,从而可保证液晶显示玻璃绑定FPC的稳定可靠。

图2为现有技术中液晶显示玻璃和FPC的焊盘设计图;
图3为图2所示技术中FPC膨胀后绑定偏移示意图;
图4为本发明提供的液晶显示玻璃和FPC的焊盘设计图;
图5为图4所示技术中FPC膨胀后导入焊盘与输出焊盘绑定示意图。
具体实施方式
参照图1,本发明提出的一种液晶显示玻璃绑定FPC的方法,液晶显示玻璃1和FPC2通过FOG绑定工艺连接。液晶显示玻璃1上设有顺序排列的导入焊盘10,FPC 2上设有输出焊盘20,输出焊盘20与导入焊盘10一一对应。当液晶显示玻璃1和FPC 2通过FOG绑定工艺连接时,输出焊盘20与导入焊盘10一一贴合。
液晶显示玻璃绑定FPC的方法中,相邻导入焊盘10之间的间距S1与相邻输出焊盘20之间的间距S2相等,所谓间距为相邻两个焊盘同一条侧边之间的距离;导入焊盘10宽度W1小于输出焊盘20宽度W2。故而,通过拓宽输出焊盘20宽度的方式降低FPC 2膨胀对输出焊盘20宽度及间距的影响。
参照图2、图3,本实施例中,导入焊盘10宽度W1=0.06mm,间距S1=0.12mm;输出焊盘20宽度W2=0.08mm,间距S2=0.12mm,即导入焊盘10宽度W1为输出焊盘20宽度W2的75%。
当液晶显示玻璃1和FPC 2通过FOG绑定工艺连接,导入焊盘10与输出焊盘20一一贴合,且随着工作时间的延长,FPC 2受热膨胀导致输出焊盘20的宽度及间距小幅度的增大。但是,由于输出焊盘20的宽度大于导入焊盘10的宽度,输出焊盘20宽度及间距的变化对导入焊盘10与输出焊盘20FOG绑定的影响大幅度降低不足以引起绑定偏移,从而可保证液晶显示玻璃绑定FPC的稳定可靠。
图2、图3所示实施例中,导入焊盘10长度L1与输出焊盘20长度L2相等且均为0.8mm,以保证导入焊盘10与输出焊盘20在长度方向上贴合的匹配程度。
具体实施时,导入焊盘10宽度W1可设置为输出焊盘20宽度W2的70%~80%。由于输出焊盘20的宽度及间距的变化幅度与其原始宽度成正比,故而,为了保证原始间距S1、S2足以克服输出焊盘20的宽度及间距的变化幅度的影响,相邻输出焊盘20之间的间距S2应该与输出焊盘20宽度W2成正比,而相邻导入焊盘10之间的间距S1始终与相邻输出焊盘20之间的间距S2相等。
以上所述,仅为本发明较佳的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本发明揭露的技术范围内,根据本发明的技术方案及其发明构思加以等同替换或改变,都应涵盖在本发明的保护范围之内。
