常見例句QFP is gull wing lead, PLCC is J-shaped lead. QFP是鷗翼形引線,PLCC是J形引線。The 1000Base-T PHY chip was taped out with CMOS process, 208 pins QFP. 本電路蓡加了 CMOS工藝流片,整個1000Base-T PHY芯片採用208琯腳QFP封裝。If test points are more than 6 nods:(1) Big BGA must be tested (2) QFP can be omitted to test. You can inspect the pad appearance instead of test. 若量測點(diǎn)超過六點(diǎn)時:(1)大顆BGA一定要量測(2)QFP可省略不量,改以目檢銲點(diǎn)的外觀來調(diào)整溫度曲線。Finite element method was used to simulate the residual stress in soldered joints of QFP device with three kinds of lead materials. 採用有限元方法對QFP器件三種引線材料銲點(diǎn)的殘餘應(yīng)力進(jìn)行了數(shù)值模擬計(jì)算分析。Now we focus on IC test handler, it's production included most of the assembly types, for example DIP,SOP,SSOP,TSSOP,QFP,TO series,QFN etc. 目前主要生産集成電路分選機(jī),産品品種涵蓋目前市場上的絕大多數(shù)封裝品種,如DIP,SOP,SSOP,TSSOP,QFP,TO系列等。Research effect of different ROL on pulling strength of QFP solder joint mainly in order to get the proper range of ROL. 主要研究了不同氧含量對QFP引腳銲點(diǎn)拉伸強(qiáng)度的影響,得到一個最佳的氧含量範(fàn)圍。 返回 QFP
