課程議題:PCBA失效分析方法及其典型的案例研究

課程背景

電子資訊時代,當我們持續不斷地改進電子產品的功能及應用範圍以滿足人們生活高需求時,產品的設計也變得越來越複雜:高密度集成PCB(HDI)越來越普遍,元器件引腳間距越來越小、排布也越來越密集等等。這些因素要求生產廠商必須擁有先進的生產設備與工藝技術、高品質的生產環境與物料。在先進設備引進與先進工藝開發過程中,我們無法避免地會遇到大量的PCBA失效問題,這就需要系統的失效分析理論來分析解決問題。在電子產品中,失效是指不能執行或提供其預期功能或輸出的設備或系統的一種狀態。用戶端產品出現的失效將會對製造方產生極度不好的影響,這些影響包括客戶對產品的不滿意或者資產損失甚至生命危險等更為嚴重的安全性問題。因此,找出產品的失效原因是十分重要的,失效原因分析將幫助我們去解決問題並防止它再次發生。

課程摘要和收穫

在本次課程中,我們將利用先進、專業、高效的分析技術與十多年的實戰經驗,結合先進工藝技術理論與經驗,通過對實際案例進行剖析,並對有關PCBA的失效分析理論系統地進行深入的探討。如斷口分析、微觀結構與成分分析、切片金相分析,化學腐蝕、電化學遷移(ECM)和微形變分析等。相關的內容包括怎樣去開展你的失效分析,可以應用到的一些方法,怎樣去幫助我們找到失效的根源,什麼時候去使用這些技巧以及一些我們曾經成功的失效分析案例。

Course Title : PCBA FA METHODOLOGIES AND TYPICAL CASE STUDIES

Course Background

The continuous research to improve product functionality and application has led electronic product to have more and more complicated design like high PCB layer counts, finer component pin pitch, densely populated board, and so on that requires advance manufacturing machines, process, environment and raw materials. But even with all these “advance” manufacturing controls and setup, we cannot avoid to have some failures that need systematic approach of analysis together with the use of sets of FA methodologies. And product failure at end customer side has a devastating effect ranging from customer dissatisfaction to a more serious problem such as safety issues that may cause loss of asset or even lives. With this, determining the root cause (s) is very important.

Course Summary and Benefits

In electronic product, failure is the state of an apparatus or system in which it cannot perform or give its intended function or output. In order to determine the cause of its failure the failure analysis engineer needs to implement the process of collecting and analysing data by using a wide array of methods. Once failure root cause is detected, it will help us fix the problem at its source and prevent it from occurring again. With our highly experienced and are experts in fields, in this presentation, we will be discussing some of the PCBA FA methodologies liked physical fracture / grain / microstructural analysis, compositional / phase diagram analysis of mixed-up alloy, corrosion/ dendrite analysis, microdeformation (µε) analysis, some tips on how to start your FA, what methodologies are applicable, how it can help to find the root cause, when to use it, and some of the actual case samples that we successfully identified for the root cause.
