Abstract

本实用新型公开了一种新型BGA器件,包含器件外壳(1)、位于器件外壳(1)表面的焊球(2),所述器件外壳(1)上与焊球(2)同一侧面设有凸台(3)。本实用新型由于凸台(3)的支撑作用,避免了BGA器件的焊球过塌陷等问题。

Description

一种新型BGA器件
技术领域
本实用新型属于电子工程领域,具体涉及电子器件的外形封装结构方式。
背景技术
BGA器件是电子产品模块中应用的非常广泛的一类器件。在BGA器件的焊接过程中,尤其是在小批量、多品种电子模块的生产中,往往由于生产数量的因素,不太可能对每一种含BGA器件电子模块的焊接炉温曲线进行详细标定,同时由于环境变化、炉温温度(焊接温度)的波动等因素,从而可能造成BGA器件焊接时的焊球过塌陷等问题,如图1A所示为焊球正常塌陷示意图,图1B为焊球过塌陷示意图。
现有的BGA器件封装没有任何预防焊球过塌陷设计(防错设计),影响了电子设备模块焊接的质量及生产效率。设计开发一种方便的预防措施,保证电子设备模块的焊接质量,提高生产效率,已成为非常需要解决的任务。
发明内容
针对现有技术的不足,本实用新型的发明目的在于提供一种新型BGA器件,由于凸台3的支撑作用,避免了BGA器件的焊球过塌陷等问题。
本实用新型的发明目的通过以下技术方案实现:
一种新型BGA器件,包含器件外壳1、位于器件外壳1表面的焊球2,所述器件外壳1上与焊球2同一侧面设有凸台3。
优选地,所述凸台3的高度为焊球2允许的塌陷后高度。
优选地,所述凸台3的数量为三个,呈三角形摆放在器件外壳1的边缘处。
优选地,所述凸台3的数量为四个,呈矩形摆放在器件外壳1的边缘处。
与现有技术相比,本实用新型的有益效果在于:本实用新型预防BGA器件的焊球过塌陷的外形封装结构形式在BGA器件中的应用,能提高电子设备模块BGA器件的焊接质量,避免返工和质量报废,因此可以节约质量成本,提高产品质量。
这种结构形式可以运用在电子器件封装、电子器件焊接等方面,稍微变换形式便可以灵活运用。具有较广阔的市场前景。

具体实施方式
下面结合附图对本实用新型作进一步的详细描述。
实施例一:
如图2A、图2B所示,对于现有的BGA器件,包含器件外壳1、位于器件外壳1表面的焊球2,在焊接前在器件外壳1的焊球面安装三个凸台3,凸台3呈三角形摆放,凸台3的高度为焊球允许(设计)的塌陷后高度,位置可灵活设置,如图4所示,焊接时就可预防焊球过塌陷等问题。
实施例二:
如图3A、图3B所示,是对实施例一的一种变形,在焊接前在器件外壳1的焊球面安装四个凸台3,凸台3呈矩形摆放。对于本领域的技术人员来说,凸台3还有多种摆放方法,在此不进行一一例举了。
