半导体bumping是什么意思?

半导体bumping是什么意思?

Bumping,一般是指倒装LED芯片(flipchip)工艺中,在wafer晶圆表面做出的铜锡或金凸点(英文就是bumping),芯片倒过来贴到PCB板上后,bumping凸点与PCB上的导电焊盘连接,用于加电驱动LED,从intel早起的CPU到现在苹果的AP处理器,都是先做bumping再和其他芯片一起做到PCB基板上成模块的。

守株待兔故事及寓意英文版?

英文版故事如下:
In the Spring and Autumn Period, a farmer in the State of Song was one day working in the fields when he saw a rabbit bump into a tree stump(树桩) accidentally and break its neck.
宋国有个农夫正在田里翻土。突然,他看见有一只野兔从旁边的草丛里慌慌张张地窜出来,一头撞在田边的树墩子上,便倒在那儿一动也不动了。农民走过去一看:兔子死了。因为它奔跑的速度太快,把脖子都撞折(shé)了。
The farmer took the rabbit home, and cooked himself a delicious meal. That night he thought, I neednt work so hard. All I have to do is wait for a rabbit each day by the stump.
农民高兴极了,他一点力气没花,就白捡了一只又肥又大的野兔。他心想;要是天天都能捡到野兔,日子就好过了。从此,他再也不肯出力气种地了。每天,他把锄头放在身边,就躺在树墩子跟前,等待着第二只、第三只野兔自己撞到这树墩子上来。
So from then on he gave up farming, and simply sat by the stump waiting for rabbits to come and run into it.
世上哪有那么多便宜事啊。农民当然没有再捡到撞死的野兔,而他的田地却荒芜了。
寓意:This idiom satirizes(讽刺,挖苦) those who just wait for a stroke of luck, rather than making efforts to obtain what they need.
这个成语用来讽刺那些坐等机遇的人,而不是通过努力而获取他们的所需。
