12 No more bump crack during handling!!!
How is Pre-Mold Features No more yield loss by mold flash! No need of back side tape No flash issue on back side when packing Increase W/B UPH! Good wire bondability Solid support for wire bond process FC Bonder /UPH ++ No more bump crack during handling!!! Reliable Flip Chip bondability Solid support for solder joint in F/C application

13 Pre-Mold Lead Frame Advantage
Process Simplification Conventional LF Packing Process LF D/BW/B Back side Taping Molding Tape Removing De-flashing Back side Plating Singulation Pre-Mold LF Packing Process (Remove plating process in Customer side ) PMLF Ni/Pd/Au Post Plated D/B W/B Molding Singulation To reduce PKG total stand off height, reduce LF thickness is KEY. Thinner LF OSATs cannot handle in assembly process…….with pre-mold make it possible! No Wasted water/chemical treatment Reduce Process, Minimize Yield Loss

15 C. 車用電子 與QFN Wettable Flank封裝

16 車用電子與QFN Wettable Flank封裝
車用IC大致上可分為微控制器(MCU)、特定應用標準產品(ASSP)/特定應用積體電路(ASIC)、類比(Analog)、功率電晶體(Transistor)、感測器(Sensor)等。(車用半導體年產值逾300億美元)

17 車用電子特性 車用電子特別要求電子元件的抗候能力，尤其是抗高溫的需求通常會優先於性能與功耗的要求。
除了高溫環境外，電子元件還會面臨衝擊與環境震動等惡劣情況，故封裝設計必須利用相對穩固的引腳設計與焊接面，來強化元件在PCB上的穩固程度。 為確保焊接點有效焊接，車用電子對導線架的要求為「必須以視覺觀察或自動化光學檢測」來確定是否為有效焊接。

18 QFN(四邊扁平無接腳(Quad Flat No Lead))
QFN體積小，類似CSP(Chip Scale Package)封裝型態，且成本相對便宜，並具有降低熱阻的特性，又因為不需要從四邊引出接腳，所以電性效能極佳，非常適用於中、低腳數的高發熱、高速/高頻系統產品。 焊接特性：QFN採用封裝底面端子作為焊接點，一般很難從其外觀的焊錫點來判斷其焊錫性是否良好，即便 QFN側面仍留有焊腳，但有些只是橫切面並未電鍍，吃錫不易。

19 Wettable Flank Wettable Flank又稱為可潤濕側翼，用於改進QFN封裝焊接特性，提高可靠性，最更重要的是，透過焊後光學檢測簡化製造過程，直接降低檢測成本。 Wettable Flank大幅提高QFN焊接品質，可符合車用電子的要求 ─ 以目視觀察焊接品質，非常適用於各種汽車電子系統應用。

20 QFN成長趨勢 2016年使用導線架封裝的IC約佔整體IC封裝的64.2%。

21 CWTC投入Wettable Flank製程優勢
長華科利用Pre-Mold技術，將經過一次蝕刻的標準QFN基板進行Molding→再做第二次蝕刻→最後電鍍。 也就是直接以第二次蝕刻去刻出台階，形成可潤濕側翼，取代掉封裝廠在Wettable Flank封裝時的額外一倍的切割工序，大幅提高良率、降低成本。
