Description

一种用于引线框键合工艺的键合装置
技术领域
本实用新型涉及一种用于引线框键合工艺的键合装置,属于半导体封装领域。
背景技术
引线键合是集成电路第一级组装的主流技术,是电子器件迅速发展的一项关键技术,在引线键合前,用热压法将高纯Si或Ge的半导体元件压在引线框所选好的位置,并用导电树脂如银浆在引线框表面涂上一层;然后借助键合装置用金属丝将半导体元件与引线框键合起来。
一方面,现有键合装置往往只是针对一个产品设计,其通用性差,从而增加了产品的生产成本;再一方面,现有键合装置往往基于引线单元一个个固定,通用性和产品均匀性较差;再一方面,固定引线框时,引线框平整性较差。
发明内容
本实用新型提供一种用于引线框键合工艺的焊接装置,该焊接装置通用性强且固定引线框时平整性优越。
为达到上述目的,本实用新型采用的技术方案是:
一种用于引线框键合工艺的键合装置,包括:
压板,此压板上开有供引线框的引线区暴露的窗口,窗口四周为用于压住引线框边框的压条;
用于支撑引线框的基板,该基板上设有用于真空吸附引线框的通孔,此通孔贯通基板上表面和下表面,此通孔位于引线框的引线区下方且其直径小于或等于0.15毫米;
所述压板和基板分别位于引线框的上方和下方。
上述技术方案中的有关内容解释如下:
1、上述方案中,所述基板下方设有两块导热金属块,该两块导热金属块分别位于所述基板两侧。
2、上述方案中,所述导热金属块为铜块或者铝块或者铝合金块。
由于上述技术方案运用,本实用新型与现有技术相比具有下列优点:
本实用新型提供一种用于引线框键合工艺的键合装置,该键合装置将压板设计成一个包含若干焊接单元的大窗口,同时,用于支撑引线框的基板采用0.15mm微细孔的通孔,采用真空吸附引线框,两者结合,避免了频繁更换键合装置且固定引线框时平整性更好;基板下方设有两块导热金属块,该两块导热金属块分别位于所述基板两侧,使得导热方面可以做到很均匀,保证了产品的均匀性。
附图说明
附图1为本实用新型压板结构示意主视图;
附图2为附图1结构示意仰视图;
附图3为附有引线框的基板结构示意主视图;
附图4为图3结构示意仰视图;
