Adi1988b. The goal of this card, baptized Supreme-FX is of course to reduce to the maximum unwanted noise by off-setting the audio circuit fromthe PCB of the motherboard.

此研究的目的卡受洗最高软体当然是为了最大限度地减少不必要的噪音减少对冲的音频电路，从电路板主机板。

In order to provide cost-effective product line telephones, voice of Po's own mold manufacturing, injection molding, circuit board production, conductive plastic production, silk screen, oil dip, electroplating, electronics assembly,"one-stop" supporting the production of , With annual output capacity of 5,000,000 telephone and medium-sized cities across the country to set up more than a dozen offices.

为了提供物美价廉的电话机系列产品，宝声公司自行模具制造、注塑、电路板制作、导电胶生产、丝印、浸油、电镀、电子装配&一条龙&配套生产，具有年产量500万部电话机生产能力，并在全国大中城市设立十几个办事机构。

In this paper, shearing machine and hammer grinder were combined to pulverize the waste boards, the metal and nonmetal on the PCBs and PWBs can be liberated availably, Then a roll-type corona-electrostatic high-voltage separator are applied to separate the metal and nonmetal, at the same time, A electrostatic separators/sizers is used to separate the mixed metals.

因此，本文采用剪切式旋转破碎机和冲击式旋转磨碎机进行两级破碎，达到金属-非金属充分解离的程度，然后应用辊式电晕-静电复合电场高压电选机，对已破碎的废弃电路板进行金属颗粒与非金属颗粒分选，同时对金属之间的分选进行理论分析和实验研究。

The design for test of PCB based on JTAG was researched from designed method, optimization strategy, realization technique and so on. Soe concrete implementing methods were given and the realization of the measurability design of the data collection circuit board of an automatic test system was also presented. The result shews that, by

阐述了JTAG技术的基本原理，从设计方法、优化策略及实现技术等方面，对基于JTAG的PCB可测性设计进行了研究，给出了具体的实现方法，并实现了自动测试系统中数据采集电路板的可测性设计。

And you only need to provide circuit board or panel processing drawings and technical requirements, we will adopt a serious, dedicated work for your service, durability, security in and on time to your suppliers.

而您只需向我们提供电路板或面板的加工图纸及技术要求，我们会以认真、热忱的工作态度为您服务，保质、保量，按时向您供货。

The complex boards need to use vias while routings; you have to be careful when using them.

They add 复杂电路板需要经过通孔来走线，当使用通孔时，需要仔细小心。

The modified asphalt is composed of 70-95 percent of petroleum asphalt and 5-30 percent of nonmetal powder of abandoned circuit boards by weight.

改性沥青由重量百分数为70～95％的石油沥青和5～30％的废弃电路板非金属粉组成。

Firstly, the smashed and sorted nonmetal powder of abandoned circuit boards is heated to 80-120 DEG C and dried for 30-60min and then added to liquid petroleum asphalt to be blended uniformly through high speed shearing, thus obtaining the modified asphalt.

先将经过破碎分选的废弃电路板的非金属粉，加热到80-120℃干燥30-60min后加入到加热到液态的石油沥青中，经高速剪切使其共混均匀，即得改性沥青。

The printed circuit assembly is IR or convection reflowed at a temperature between approximately 280 and 290 degrees C, and maintains solder connection integrity when the printed circuit assembly (36) is later incorporated into a second printed circuit assembly using a standard tin-lead solder system.

该印刷电路组件在约280―290℃的温度下通过IR或对流加热而发生回流，并且当该印刷电路组件（36）随后通过标准的锡―铅焊料系被安装至第二印刷电路板时维持焊料连接整体性。

This feature redefines the board shape based on a surface of an imported 3D STEP model.

此功能重新定义了电路板的通过所导入的3D step模型的平面。

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.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
