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(jì)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(diǎn)
適用于表面貼裝封裝,是具有多個(gè)電極觸點(diǎn)和一個(gè)用于機(jī)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(jì)使其占有更小的PCB面積??紤]到成本、體積各方面的因素,QFN、DFN封裝將會(huì)是未來幾年的一個(gè)增長(zhǎng)點(diǎn),發(fā)展前景較為樂觀。
應(yīng)用
QFN和DFN被認(rèn)為是最成熟的行業(yè)封裝標(biāo)準(zhǔn)之一。QFN和DFN是常用的邏輯、存儲(chǔ)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(diǎn)
參考或達(dá)到JEDEC標(biāo)準(zhǔn)
定制化設(shè)計(jì)引線框架設(shè)計(jì)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
