倒装芯片

Flip chip(倒装芯片)：一种无引脚结构，一般含有电路单元。设计用于通过适当数量的位于其面上的锡球(导电性粘合剂所覆盖)，在电气上和机械上连接于电路。

起源于60年代，由IBM率先研发出，具体原理是在I/Opad上沉积锡铅球，然后将芯片翻转加热利用熔融的锡铅球与陶瓷板相结合，此技术已替换常规的打线接合，逐渐成为未来封装潮流。Flip Chip既是一种芯片互连技术，又是一种理想的芯片粘接技术．早在30年前IBM公司已研发使用了这项技术。但直到近几年来，Flip-Chip已成为高端器件及高密度封装领域中经常采用的封装形式。今天，Flip-Chip封装技术的应用范围日益广泛，封装形式更趋多样化，对Flip-Chip封装技术的要求也随之提高。同时，Flip-Chip也向制造者提出了一系列新的严峻挑战，为这项复杂的技术提供封装，组装及测试的可靠支持。以往的一级封闭技术都是将芯片的有源区面朝上，背对基板和贴后键合，如引线健合和载带自动健全（ＴＡＢ）。ＦＣ则将芯片有源区面对基板，通过芯片上呈阵列排列的焊料凸点实现芯片与衬底的互连．硅片直接以倒扣方式安装到ＰＣＢ从硅片向四周引出Ｉ／Ｏ，互联的长度大大缩短，减小了ＲＣ延迟，有效地提高了电性能．显然，这种芯片互连方式能提供更高的Ｉ／Ｏ密度．倒装占有面积几乎与芯片大小一致．在所有表面安装技术中，倒装芯片可以达到最小、最薄的封装。

Flip chip又称倒装片，是在I/O pad上沉积锡铅球，然后将芯片翻转佳热利用熔融的锡铅球与陶瓷机板相结合此技术替换常规打线接合，逐渐成为未来的封装主流，当前主要应用于高时脉的CPU、

GPU(GraphicProcessor Unit)及Chipset 等产品为主。与COB相比，该封装形式的芯片结构和I/O端（锡球）方向朝下，由于I/O引出端分布于整个芯片表面，故在封装密度和处理速度上Flip chip已达到顶峰，特别是它可以采用类似SMT技术的手段来加工，因此是芯片封装技术及高密度安装的最终方向。倒装片连接有三种主要类型Ｃ４(Controlled Collapse Chip Connection)、ＤＣＡ(Direct chip attach)和ＦＣＡＡ(Flip Chip Adhesive Attachement)。

Ｃ４是类似超细间距ＢＧＡ的一种形式与硅片连接的焊球阵列一般的间距为0.23、 0.254mm。焊球直径为0.102、0.127mm。焊球组份为97Pb/3Sn。这些焊球在硅片上可以呈完全分布或部分分布。

由于陶瓷可以承受较高的回流温度，因此陶瓷被用来作为Ｃ４连接的基材，通常是在陶瓷的表面上预先分布有镀Au或Sn的连接盘，然后进行Ｃ４形式的倒装片连接。Ｃ４连接的优点在于：

１）具有优良的电性能和热特性

２）在中等焊球间距的情况下，Ｉ／Ｏ数可以很高３）不受焊盘尺寸

的限制

４）可以适于批量生产

５）可大大减小尺寸和重量

ＤＣＡ和Ｃ４类似是一种超细间距连接。ＤＣＡ的硅片和Ｃ４连接中

的硅片结构相同，两者之间的唯一区别在于基材的选择。ＤＣＡ采用的基

材是典型的印制材料。ＤＣＡ的焊球组份是97Pb/Sn，连接焊接盘上的焊料是共晶焊料（37Pb/63Sn)。对于ＤＣＡ由于间距仅为0.203、0.254mm共晶焊料漏印到连接焊盘上相当困难，所以取代焊膏漏印这种方式，在组装前

给连接焊盘顶镀上铅锡焊料，焊盘上的焊料体积要求十分严格，通常要比

其它超细间距元件所用的焊料多。在连接焊盘上0.051、0.102mm厚的焊料由于是预镀的，一般略呈圆顶状，必须要在贴片前整平，否则会影响焊球

和焊盘的可靠对位。

ＦＣＡＡ连接存在多种形式，当前仍处于初期开发阶段。硅片与基材

之间的连接不采用焊料，而是用胶来代替。这种连接中的硅片底部可以有

焊球，也可以采用焊料凸点等结构。ＦＣＡＡ所用的胶包括各向同性和各

向异性等多种类型，主要取决于实际应用中的连接状况，另外，基材的选

用通常有陶瓷，印刷板材料和柔性电路板。倒装芯片技术是当今最先进的

微电子封装技术之一。它将电路组装密度提升到了一个新高度，随着２１

世纪电子产品体积的进一步缩小，倒装芯片的应用将会越来越广泛。

Flip-Chip封装技术与传统的引线键合工艺相比具有许多明显的优点,

包括,优越的电学及热学性能,高I/O引脚数，封装尺寸减小等。

Flip-Chip封装技术的热学性能明显优越于常规使用的引线键合工艺。如今许多电子器件；ASIC，微处理器，SOC等封装耗散功率10-25W，甚至

更大。而增强散热型引线键合的BGA器件的耗散功率仅5-10W。按照工作条件，散热要求（最大结温），环境温度及空气流量，封装参数（如使用外

装热沉，封装及尺寸，基板层数，球引脚数）等，相比之下，Flip-Chip封装通常能产生25W耗散功率。

Flip-Chip封装杰出的热学性能是由低热阻的散热盘及结构决定的。芯片产生的热量通过散热球脚，内部及外部的热沉实现热量耗散。散热盘与

芯片面的紧密接触得到低的结温（θjc）。为减少散热盘与芯片间的热阻，在两者之间使用高导热胶体。使得封装内热量更容易耗散。为更进一步改

进散热性能，外部热沉可直接安装在散热盘上，以获得封装低的结温（θjc）。

Flip-Chip封装另一个重要优点是电学性能。引线键合工艺已成为高频及某些应用的瓶颈，使用Flip-Chip封装技术改进了电学性能。如今许多

电子器件工作在高频，因此信号的完整性是一个重要因素。在过去，2-3GHZ

是IC封装的频率上限，Flip-Chip封装根据使用的基板技术可高达10-40 GHZ 。

(完整版)部分倒装与完全倒装的区别

部分倒装与完全倒装的区别英语最基本的词序“主语部分+谓语部分”通常十分固定。如果把谓语动词放在主语前面，这就叫做倒装。将谓语动词完全移至主语之前，称为完全倒装；如果只是把助动词或情态动词放在主语之前，称为部分倒装。一、全部倒装 1．以here，there，now，then开头的句子,谓语动词要放在句子的主语之前。这种句子中的谓语动词通常是不及物动词。如： Here comes the train！ There goes the bell！注意：如果句子的主语是人称代词，则不能使用倒装结构。如： Here it comes！／There it goes！ 2．有些动词短语以副词out，in，up，down，away等结尾，构成不及物动词短语。这时，为了使句子更形象，常将这些副词提前到句首。这时，句中的谓语动词要放在句子主语的前面，构成全部倒装。（注意，这时句子的主语也必须是名词。如果是人称代词，也不能使用倒装结构。）如： Up went the rocket． Up it went． 3．为了强调表示地点的介词短语，常将这个介词短语放在句首，构成全部倒装。注意，这时句子的谓语动词通常是不及物动词。如： In the front of the lecture hall sat the speaker． 4．表语置于句首，且主语较长或结构较复杂的句子要用全部倒装。如： Gone are the days when we had nothing to eat． 5．so／neither／nor表示前面所说的情况也适合于后者，其倒装结构为“so／neither ／nor＋助动词／系动词／情态动词＋主语”（so表示肯定意义，neither／nor表示否定意义）。如： She has finished her homework，so has her brother． She hasn’t gone there，neither／nor has he．但如果so表示强调，即强调前面所说的情况的真实性时，其结构是“so＋主语＋助动词／系动词／情态动词”，这里的主语同前一个句子的主语指的是同一人或物。如：She knows little English，so she does．她英语懂得不多。她的确如此。二．部分倒装 1．用于疑问句中。如： How did you do that﹖ Did you see the film yesterday﹖ 2．用于省略if的虚拟条件状语从句中。如果我们将连词if省略，应把were，had，should提到主语前面。如： If you had come yesterday，you would have seen him． →Had you come yesterday，you would have seen him． 3．用于as引导的让步状语从句中。as引导的让步状语从句引起的倒装有以下几种形式： 1) 副词置于句首。如： Much as I like it (＝Although I like it very much), I will not buy it．

英语倒装句(最全面_最简洁)

英语句子的自然顺序是主语在前,谓语在后（主语+谓语）。把谓语动词放在主语之前（谓语+主语）,就叫倒装结构。如果全部谓语放在主语之前, 叫全部倒装; 如果只把助动词或be 动词放在主语之前就叫部分倒装。基本语序（natural order）：主语+谓语+宾语（subject + predicate+ object） I love English. 完全倒装 (full inversion) 谓语+主语 Here came the headmaster. 部分倒装 (partial inversion) 助动词/情态动词+ 主语 + 动词 Nerve will I forgive you. 一、完全倒装 1. There be结构。另外,在此结构中可以用来代替be动词的动词有:exist, seem, happen, appear, live, rise, stand等。 There stood a dog before him. There exist different opinions on this question. 例题: ________ a beautiful palace ________ the foot of the hill. A. There stand; at B. There stands; under C. Stands there; under D. There stands; at 2 (1).在以here、there、now、then等副词开头的句子里。句式：副词＋vi＋名词主语 “Here, There, Now, Then + come (或be,go,lie,run) + 主语" 结构。 Here comes the old lady! Then came the hour we had been looking forward to. Now comes your turn. 如果主语是人称代词,主语和谓语语序不变，不用倒装。如:Here you are. There she comes. (2).表示方向的副词out, in, up, down等置于句首,要用全部倒装。如果主语是人称代词,就不用倒装。如: In came Mr. White. Up went the arrow into the air. Away went the boy. 题：There ________. And here ________. A. goes the phone; she comes B. is the phone going; is she C. does the phone go; does she come D. the phone goes; come she 3.当表示地点的介词词组(如on the wall, under the tree, in front of the house, in the middle of the room等)在句首时。句式：介词短语＋vi＋主语（必须是名词）如：At the foot of the hill lies a beautiful lake. East of the lake lie two towns. Under the tree was lying a wounded soldier.

句子倒装

英语最基本的语序是主语在前，谓语动词在后。但有时由于句子结构的需要或表示强调，就要采用倒装形式。将谓语动词完全移到主语之前称为完全倒装，只将助动词或情态动词放到主语之前称为部分倒装。强调性倒装和以so, neither, nor开头的句子是高考例题的热点。（一）倒装句的意义 1、适应一定的语法结构的需要，主要是指疑问句句型结构的需要。 e.g. May I come in? Was the People's Liberation Army founded in 1927? 2、为了强调某一部分，而把这部分放到句首，构成倒装。 e.g. Never have I been late for school this term. So early did he come to school that no other students came. （二）倒装的使用情况 1、在"there be" 结构里，there是引导词，主语在be后。 e.g. There is a box on the table. 2、在疑问句中。 e.g. Is she singing in the classroom? What does your mother do? 3、在here, there等副词开头的某些句子里（要用一般现在时态）。如果主语是人称代词，主语和主要动词的词序不变。（完全倒装） e.g. There goes the bell. Here is an apple for you. There she comes. 4、重复倒装句型，用在以so, nor, neither开头，表示谓语所述的情况也适用于另一个人或一事物的肯定或否定句中。so用于肯定句，表示"也一样"、"也这样"；nor, neither用于否定句，表示"同样也不，也不这样"。 e.g. I am watching TV. So is she.

英语倒装练习题

倒装知识总纲英语的基本语序是“主语＋谓语”如果将谓语放在主语之前，这种语序叫做倒装。倒装分为两种：全部倒装和部分倒装。在倒装语序中若整个谓语都在主语之前称为全部倒装；若谓语的一部分（情态动词或助动词）位于主语之前称之为部分倒装。 1、全部倒装 1、以介词开头的地点状语位于句首。例：In front of the house stand a lot of trees. 注：谓语动词要与其后的主语保持时态和数的一致。 2、表示时间和方位的副词there, here, out, off, now, up, down等,位于句首。例：Here came a bus. 注：若主语是人称代词时则用正常语序。如：Here you are. 3、such位于句首。例：Such was Doctor Li. 4、表语位于句首。例：Gone are the days when we lived in that city. 5、直接引语的一部分或全部位于句首。例：“Don’t do it again!” said the mother to her son. 注：如果主语是代词时则不倒装。如：“What are you doing?” he asked. 6、为了使全句平衡，而将较长的主语放在句末。例：Among these men was a man called Tom. 2、部分倒装 1、否定词或否定短语位于句首时,常见的否定词或否定短语有： no, not, never, hardly, scarcely, little, seldom, not until, no sooner…than…, hardly…when…, not only…but also…, in no time, in no way,

部分倒装和完全倒装

部分倒装和完全倒装 1. 完全倒装 1) 完全倒装即把整个谓语放到主语之前（是整个谓语动词，而非助动词）。例如：In came the teacher and the class began. （老师走了进来，然后开始上课。） 2) there引出的完全倒装句：除了最常见的there be句型以外，there还可以接appear, exist, lie, remain, seem to be, stand等，一般都译成"有"的含义，构成完全倒装句。例如：There appeared to be a man in black in the distance.（远处有个穿黑色衣服的人。）3) 由地点和时间副词引出的完全倒装句：以地点副词here, there和时间副词now, then 开头，后面的动词是be, come, exist, fall, follow, go, lie, remain, seem, stand等，而主语又是名词时，构成完全倒装句。例：Under that tree sits a beautiful girl.（那棵树下坐着一位美丽的姑娘。）例：_________ from the tenth floor when the policeman pointed his pistol at him. A) Jumped down the burglar B) Down the burglar jumped C) The burglar jumps down D) Down jumped the burglar 答案是D) Down jumped the burglar。因为地点状语Down位于句首应该用完全倒装，整个谓语动词应位于主语之前。C) The burglar jumps down虽然是自然语序，但时态错误，应该用和时间状语从句一致的过去时，而不是现在时。注意： 1) 在here, there引出的倒装句中，当主语是普通名词时用完全倒装句，但当主语是代词时，就要用部分倒装句。例：Here comes the postman!（邮递员终于来了！注意实意谓语动词位于主语之前。）Here we are.（我们到了。注意系动词位于主语代词之后。） 2) 注意正语序和倒装语序的语气、意义是区别：例：Here is the picture I love.（这正是我所喜爱的画。） The picture I love is here.（我所喜爱的画在这里。） 3) 当主语是代词，谓语是系动词，表语是说明性的词、词组和定语从句时，可以使用完全倒装句，起强调作用。例：Lucky is he who has been enrolled into a famous university.（他真幸运，被一所名牌大学录取了。） 2. 部分倒装 1) 部分倒装即只把谓语的一部分（如助动词、情态动词等）放到主语前，或把句子的强调成分提前。例：_______ right now, she would get there on Sunday. A) Would she leave B) if she leave C) were she to leave D) If she had left 结合选项，全句的意思是：“如果她立刻就走，她就能在星期天到达那里”。答案是C。 2) 以否定词开头的句子要求部分倒装。注意下列句子中助动词或情态动词提前、甚至补充助动词的用法：例：Not until yesterday did little John change his mind.（小约翰直到昨天才改变了主意。）例：In no country ______ Britain, it had been said, can one experience four seasons in the course of a single day.
