裸晶 的英文怎麼說
中文拼音 [luǒjīng]
裸晶
英文
bare crystal-
Finite element method ( fem ) was used to simulate thermal and vibration problems in stacked - die csp assembly. finite element models and apdl programes were built in ansys to conduct thermal, thermal - mechanical and vibration analysis. the aim of these researches were trying to find some possible reasons and trends which affect the reliability of stacked csp / bga assembly and give some useful suggestions for the packaging design
本論文正是針對以上情況，以採用引線鍵合工藝的三維疊層csp / bga封裝（裸晶元疊裝）為研究對象，在有限元分析軟體ansys中建立相關的有限元模型，編制了相應的apdl參數化分析程序，進行了溫度場分析、熱循環加載下的snpb合金焊點疲勞分析和實裝pcb板的振動模態分析。The accelerometer which has simple fabricated process and high sensitivity and small parasitic capacitance and residual stress is hybrid integrated with the interface circuit using ic nude chip. so the density of the package is increased, and the noise of the sensing system is decreased. these found the base of capacitive accelerometer module using the mcm method
該傳感器製作工藝簡單，靈敏度高，支撐梁採用u型，減小了刻蝕后的殘余應力，用玻璃作為襯底，減小了襯底和硅可動質量塊間的寄生電容，且把傳感器晶元和用ic裸片製作的介面電路集成在一起，提高了封裝密度，減小了傳感器系統的噪聲，為採用mcm技術製作電容式加速度傳感器模塊打下了基礎。Multichip module ( mcm ) is high - level mode in electronic package. mcm is that bare dice and microelements are assembled on a high - density interconnection ( hdi ) substrate. mcm can meet the demands of compact packaging and high density
多晶元組件（ mcm ）是微電子封裝的高級形式，它是把裸晶元與微型元件組裝在同一個高密度布線基板上，組成能夠完成一定的功能的模塊甚至子系統。In a world full of sbcs with loose power leads, giant " wall wart " power supplies, elaborate power requirements, and exposed chips, it s nice to have a box where, once the hard drive is in it, it takes a standard electrical outlet two - prong, even, for those of you in older houses and just works
在一個全部由sbc組成的世界中，有鬆散的電源線，巨大的「 wall wart 」電源，復雜的電源要求，以及裸露的晶元，最好有一個機箱，這樣，一旦裝入了硬盤驅動器，它使用標準的插座（甚至是兩個尖頭的那種，用於老房子之中的）就可以正常工作。The result shows that forming a high capability ac control ic using this ip as an embedded core with other cpu or dsp core can efficiently shorten the cpu processing time and constitute high performance close - loop control system. some of the ips about the communication between d / a convert, i2c devices and control ics are also created
這種速度估算ip核作為一種通用的片內外設形式（以硬體形式完成軟體功能） ，和裸mcu （或dsp ）核製成電機控制專用晶元，可應用於各種無速度傳感器的電機控制場合。分享友人
