电路板

A layout program for a PC board might see two lines intersecting and say,"uh-oh, we have a short circuit here and there's a conflict."

但是，如果是在PC机的电路板上有两条线重叠了，那就是短路了。

Printed Circuit Board. The main system software is located in ROM on the SBC. The SBC communicates with the rest of the Gammacell Irradiator and voltage shifting for all

计算机控制柜由单板机和输入/输出印刷电路板组成，主要的系统软件就安装在SBC的ROM中。

Maintenance of its failure as follows: First of all, the shell open the keyboard, with a soft brush to clear the board of the dirt, while the use of anhydrous alcohol to clean the keyboard and keycap button below to contact the part after cleaning for testing.

其故障维修方法为：首先拆开键盘的外壳，用软毛刷将电路板上的污垢清除，同时使用无水酒精清洗键盘按键下面与键帽接触的部分，清洁后进行测试。

Applied extensively to knitting horizontal machine, needle trough cutting, printed circuit board, V trough cutting, integrated circuit cutting, spectacle frame, hinge shaping, hardware processing, watchcase and watchband processing, and high-performance optic fibre cable cutting.

广泛适用于针织横机针槽切割，印刷电路板V槽切割，集成电路切割，眼镜架、铰链成型，精密五金金属加工、手表表壳、表带加工，高性能光纤电缆切割。

Account to compare with the traditional frequency, the single-chip-machine frequency that join together accounted to simplify with the FPGA the electric circuit knothole designs, increasing the system design of realize sex with dependable, measure the scope of frequency comes to an a software for, realizes arithmetic figure system hardware turns, this is the new trend that arithmetic figure logic design.

和传统的频率计相比，单片机和FPGA结合的频率计简化了电路板的设计，提高了系统设计的实现性和可靠性，测频范围达到了100MHz，实现了数字系统硬件的软件化，这是数字逻辑设计的新趋势。

Both the single and 2-axis devices are packaged in 5mm x 5mm ceramic leadless chip carriers and are intended for surface mounting on printed circuit boards.

不论单轴还是两轴元件都封装在5mm x 5mm陶瓷无铅晶片载体内，并可表面贴装在印刷电路板上。

Are discussed. Logical test can identify and diagnose PCB's fault through the difference of logic voltage level.

本文第2章针对这种变化讨论了印刷电路板检测中的若干基本问题。

Source Module to provide digital modulation module base-band and bit synchronization signal BS (in experimental circuit board connected Link without manual wiring).

信源模块向调制模块提供数字基带信号和位同步信号BS（已在实验电路板上连通，不必手工接线）。

WhatIF -- an Intermediate Frequency planning tool for RF system architects;* Spectrasys -- the only continuous-spectrum RF system simulator with root-cause analysis; and* Synthesis -- eight design assistants that implement manufacturable circuit-level designs, such as precise image-reject filters for RF boards.

ADS 2006A提供的新功能包括：WhatIF──RF系统架构设计用的IF规划工具；Spectrasys──具有根本原因分析能力的连续频谱RF系统仿真器；以及Synthesis──含八套设计助理功能，可以实做出易于生产的电路层级设计，例如RF电路板用的精确型镜像抑制(image-reject)滤波器。

At recent decade, accompany with Surface Mount Technology printed-circuit board to produce fly of automation degree to soon develop, as to it's correspond of mass defect the inspection also put forward higher request, from in brief shoot to be like system to complicated 3-DX optics to examine system, the Automatic Optical Inspection is in great quantities adopt by the each production factory house.

摘要在最近十年，伴随着表面贴装印刷电路板生产自动化程度的飞速发展，对其相应的质量缺陷检查也提出了更高的要求，从简单的摄像系统到复杂的3-DX光检测系统，自动光学检测系统大量被各生产厂家采用。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
