QFN

產(chǎn)品和服務(wù)

產(chǎn)品介紹
Quad Flat No-lead Package的縮寫，即四邊扁平無引腳封裝；QFN的設(shè)計和應(yīng)用與DFN類似。QFN和DFN的主要差異在于引腳只排列在產(chǎn)品下方的兩側(cè)而不是四周

產(chǎn)品特點
適用于表面貼裝封裝，是具有多個電極觸點和一個用于機械和熱量完整性暴露的芯片墊的無鹵封裝。無引腳焊盤設(shè)計使其占有更小的PCB面積。考慮到成本、體積各方面的因素，QFN、DFN封裝將會是未來幾年的一個增長點，發(fā)展前景較為樂觀。

應(yīng)用
QFN和DFN被認為是最成熟的行業(yè)封裝標準之一。QFN和DFN是常用的邏輯、存儲器和微控制器。應(yīng)用于安全芯片、車用電子、醫(yī)用設(shè)備電子、數(shù)字化視頻、射頻、數(shù)據(jù)采集、電平轉(zhuǎn)換器、變頻器、通用MCU、車載音頻處理器、鋰電池充電管理芯片

工藝特點
參考或達到JEDEC標準
定制化設(shè)計引線框架設(shè)計和多規(guī)格焊盤尺寸，以滿足不同客戶需求
綠色制造、無鉛工藝
