电路板

Tip: In order to display the work efficiently, we must not lose sight of its environment, for example, can not be allowed to work in an environment of dust Dancer in the display when not in use dust mask must cover the display cover, or keep the dust attached to the display's internal components, circuit boards, which may affect the normal display of heat distribution, so that components, circuit board along with the rise in temperature to accelerate the pace of aging, affecting the life of the display.

小提示：为了能让显示器高效工作，我们千万不能忽视它的使用环境，例如不能让其工作在灰尘漫舞的环境中，在不使用显示器时必须用遮尘罩盖住显示器，不然灰尘不断地附着在显示器内部的元器件、电路板上，从而可能影响显示器热量的正常散发，以致于元器件、电路板随着工作温度的上升，加快老化速度，影响显示器的使用寿命。

All sales of equipment were free distribution reserve a circuit board, circuit boards free maintenance for life;整机problems within one year of free on-site service.

公司销售的所有仪器均随机免费配送备用电路板一块，电路板终身免费维修；一年内整机出现问题免费上门服务。

When manufacturing PCB, the drill pin's quality is an important factor to ensure the PCB's eligibility.

在印制电路板制造过程中，钻针的质量对于保证所钻电路板的合格性起着非常重要的作用。

RD auto pinning machine is used to make reference positioning pin prior to drill the laminated plates of etched circuit card on drill machine for etched circuit card manufacture premium products.

RD全自动钉销机用于印刷电路叠层板在印制电路板数控钻床钻孔前钻作基准定位销钉，从面保证印刷电路板数控钻床能加工出高品质的产品。

The disadvantage of this approach is that additional devices are required on the circuit board, driving up cost and board area.

这种办法的缺点是，需要额外的设备上的电路板，推高的成本和电路板面积。

Etchants are high consumption and high pollution of the printed circuit board industry; therefore this research uses the etchant for the acid copper chloride amount the high copper content in the printed circuit board industry, using the neutralization for acids and bases to prepare of the copper salt by the acid wasted etching liquid.

中文摘要在印刷电路板业中蚀刻液属於高用量及高污染性质的液体；因此本研究主要使用印刷电路板业中含铜量较高之酸性氯化铜蚀刻液，使用酸碱中和法从酸性蚀刻废液制备出铜盐，以达到废弃物资源化再利用之永续经营。

We were established in 1997 to design and manufacture pc board, doublesided pc board and multi layer pc board.

本公司建立於1997年，专门设计制作电路板，双面板及多层印刷电路板。

In 2002 the company developed and produced the "duplex-bit multi-layer circuit board pre-Permian point fusion machine BM-II" dedicated circuit board equipment, by the State Intellectual Property Office of the Chinese Patent Office granted patent approval.

2002年度公司开发生产的&双工位多层电路板预叠点熔合机BM-II&电路板专用设备，经国家知识产权局中国专利局核准授予专利证书。

Drilling needle grinding and disposal Process Description : Note the use of needle drilling Content : drilling needles is the main circuit board drilling consumables, the most profound impact on circuit board drilling costs, the majority of the larger diameter needle drilling will engage in further grinding.

钻针研磨及排放制程说明：说明钻针的运用工作内容：钻针是电路板钻孔主要的耗材，极度影响电路板钻孔的成本，因此多数较大孔径的钻针都会从事再研磨。

A total of 14 book chapters and two appendices, a comprehensive introduction to the work of Protel 99 interface, the basic composition, a variety of commonly used editors and basic knowledge of common tools, and circuit design in accordance with the general process, starting from the user requirements, to the printout printed circuit board plate making plans until a detailed description of the circuit schematic design, netlist generation, single-sided and double-sided printed circuit board design method and the steps and so on.
