论文 Chemical mechanical polishing
The planarization technology of Chemical-Mechanical-Polishing (CMP), used for the manufacturing of multi-
level metal interconnects for high-density Integrated Circuits (IC), is also readily adaptable as an enabling technology
in MicroElectroMechanical Systems (MEMS) fabrication, particularly polysi ...
文章/文档 We obtained the energy transport velocity distribution for a three dimensional ideal cloak explicit
We obtained the energy transport velocity distribution for a three dimensional ideal cloak
explicitly. Near the operation frequency, the energy transport velocity has rather peculiar
distribution. The velocity along a line joining the origin of the cloak is a constant, while
the velocity approaches ...
技术资料 93C46英文版
The Microchip Technology Inc. 93C46B is a 1K-bit,
low-voltage serial Electrically Erasable PROM. The
device memory is configured as 64 x 16 bits. Advanced
CMOS technology makes this device ideal for
low-power, nonvolatile memory applications. The
93C46B is available in standard 8-pin DIP, surface
mo ...
书籍 SDN Software Defined Networks
The first question most readers of an O’Reilly book might ask is about the choice of the
cover animal. In this case, “why a duck?” Well, for the record, our first choice was a
unicorn decked out in glitter and a rainbow sash.
That response always gets a laugh (we are sure you just giggled a littl ...
技术资料 基于单片机控制的便携式电火花打孔机的设计
针对现有的便携式电火花打孔机质量太大、加工效率低等问题,在分析总结了现有的便携式电火花打孔机研究现状的基础上,提出了一种滑块静止而导轨运动的执行机构设计方案。基于单片机,研究了直接利用RC比较电路以简化放电回路的方法,使用了千分表座作为便携式电火花打孔机的底座以调整打孔面,制作出的便携式电火花打孔机重量减 ...
电源技术 LTM4601 DC/DC微型模块性能
 
The LTM4601 DC/DC μModule regulator is a completehigh power density stepdown regulator for up to 12Acontinuous (14A peak) loads. The device is housed ina small 15mm ¥ 15mm ¥ 2.8mm LGA surface mountpackage, thus the large power dissipation is a challengein some applications. Thi ...
模拟电子 VGA 8:1 multiplexer reference
This reference design (RD) features a fullyassembled and tested surface-mount printed circuitboard (PCB). The RD board utilizes the MAX48851:2 or 2:1 multiplexer and other ICs to implement acomplete video graphics array (VGA) 8:1multiplexer.VGA input/output connections are provided to easilyinterfac ...
PCB相关 计算FR4上的差分阻抗(PDF)
Calculation of the Differential Impedance of Tracks on FR4 substrates
There is a discrepancy between calculated and measured values of impedance for differential transmission lineson FR4. This is especially noticeable in the case of surface microstrip configurations. The anomaly is shown tobe due to ...
