SMT CHINA编译报道：3月7日（周三）在德国Böblingen举行的EPP创新论坛上，全球电子焊接和粘合材料生产领导者爱法组装材料 (Alpha Assembly Solutions)将展示可减少空洞的预成型解决方案。

该公司DACH区客户技术支持经理Ralph christ将于会上发表演讲，重点介绍电子组装工艺的优化方案之一，即如何通过使用ALPHA TrueHeight来防止BGA桥接，以及通过使用ALPHA^" TrueHeight^"预成型焊片来防止半导体应用中出现的芯片倾斜，并确保具备一致的粘合层厚度。

Ralph christ解释道， TrueHeight预成型焊片采用了嵌入式间隔技术，是防止回流焊后BGA桥接的有效方法，在无毛刺鼓胀的焊盘上涂覆了镍阻挡层之后又在表面覆金。它们被设计成自动下料并回流到PCB焊盘上，从而在BGA的某小角落实现预定的最小高度。这可以防止焊球过度塌陷从而导致相邻桥接。

为了优化半导体应用，ALPHA TrueHeight预成型件设计用于提供一致的粘合层厚度和最小的die倾斜度，如此可以保障焊接的可靠性和电子性能。

今年EPP创新论坛的重点是工艺优化，该活动的主要目的是传递知识并继续保持和扩大德国电子产品的竞争力。本次活动将邀请一些重点行业的专业人士，他们将分别就该主题发表20分钟的演讲。（SMTC@ACT）
