EMC设计方法

原理图的EMC设计1．整机原理图设计时各功能电路要区分明确，以便于电路分析。

2．各部分是否尽量使用更低速的器件？(如74HC14的T r=T f=6ns而74AHC14的T r=T f≤3ns，这时我们就要考虑尽量选用74HC14而不是74AHC14.)3．对DVD机芯的干扰是否有EMI对策，原理图上要明确标注。

解释说明：DVD机芯的干扰主要是激光头电路本身产生的干扰（不同厂家的机芯干扰程度不一样），激光头的干扰通过较长的激光头扁平线形成天线辐射，所以要在电路上加小电容减少扁平线的天线效应，如下图。

4．DVD机芯电源要有EMI对策，不但要明确标注而且要注明Layout 时的放置位置。

解释说明：由于激光头读取信息时电源瞬间变化所产生的干扰很大。

机芯电源要求就近有能提供瞬态电流的电容。

如下图虚线框内的EMI对策，有的机芯电路有好几个电源，每个电源都要有电容滤波，至少要有一个102---104的电容。

5．原理图上要标注各功能块的工作电压，尤其是时钟信号工作频率要描述清楚？（如：解码芯片、RAM芯片、DC/DC 等）解释说明：原理图上标注清楚工作电压和信号频率不但有利于原理图的评审，对PCBLayout也有很大的指导作用。

6．对于干扰较大的3、5次谐波频率在230MHz左右的时钟频率能否调整？（要求F3、F5＞230MHz+20MHz）解释说明：因为CE辐射测试标准里有两个频率段（30MHz----230MHz和230MHz---1GHz），高段比低段要求低7Db。

在EMC整改时要降7DB需要增加很多对策，尤其是针对LCD屏的干扰，我们很难对屏进行处理。

7．对较高频率是否有EMI对策？如RAM时钟等。

解释说明：工作频率比较高的时钟信号不但其产生的谐波辐射很大，其本身的基波辐射也很大，所以原理图上一定要有EMI对策。

如MTK1389与DRAM的工作时钟，频率为108MHz/128MHz/135MHz，在原理图上要串联电阻和并联电容到地。

74AHC573 74AHCT573 CMOS 高速透明储存器说明书

74AHC573; 74AHCT573Octal D-type transparant latch; 3-stateRev. 7 — 8 November 2011Product data sheet1. General descriptionThe 74AHC573; 74AHCT573 is a high-speed Si-gate CMOS device and is pin compatiblewith Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standardNo.7A.The 74AHC573; 74AHCT573 consists of eight D-type transparent latches featuringseparate D-type inputs for each latch and 3-state true outputs for bus orientedapplications. A latch enable input (LE) and an output enable input (OE) are common to alllatches.When pin LE is HIGH, data at the Dn inputs enters the latches. In this condition thelatches are transparent, i.e. a latch output will change state each time its correspondingDn input changes. When pin LE is LOW, the latches store the information that is presentat the Dn inputs, after a set-up time preceding the HIGH-to-LOW transition of LE.When pin OE is LOW, the contents of the 8latches are available at the outputs. Whenpin OE is HIGH, the outputs go to the high-impedance OFF-state. Operation of the OEinput does not affect the state of the latches.The 74AHC573; 74AHCT573 is functionally identical to the 74AHC373; 74AHCT373, buthas a different pin arrangement.2. Features and benefits⏹Balanced propagation delays⏹All inputs have a Schmitt trigger action⏹Common 3-state output enable input⏹Functionally identical to the 74AHC373; 74AHCT373⏹Inputs accept voltages higher than V CC⏹Input levels:◆For 74AHC573: CMOS input level◆For 74AHCT573: TTL input level⏹ESD protection:◆HBM EIA/JESD22-A114E exceeds 2000V◆MM EIA/JESD22-A115-A exceeds 200V◆CDM EIA/JESD22-C101C exceeds 1000V⏹Multiple package options⏹Specified from -40︒C to +85︒C and from -40︒C to +125︒C3.

1. General description74AHC1G126 and 74AHCT1G126 are high-speed Si-gate CMOS devices. They provideone non-inverting buffer/line driver with 3-state output. The 3-state output is controlled by the output enable input pin (OE). A LOW at pin OE causes the output to assume a high-impedance OFF-state.The AHC device has CMOS input switching levels and supply voltage range 2 V to 5.5 V.The AHCT device has TTL input switching levels and supply voltage range 4.5 V to 5.5 V.2. Features and benefits⏹Symmetrical output impedance ⏹High noise immunity ⏹Low power dissipation⏹Balanced propagation delays ⏹Multiple package options ⏹ESD protection:◆HBM JESD22-A114F: exceeds 2000V ◆MM JESD22-A115-A: exceeds 200 V ◆CDM JESD22-C101E: exceeds 1000V ⏹Specified from -40︒C to +125︒C3.

AHC(Advanced Heat Control：热量适应控制)概要传统上，电阻焊接控制装置以保持一定电流的定电流控制为主流。

定电流控制无法补偿外部的干扰，板间间隙，粘有垃圾和分流等原因，发生飞溅，焊接品质无法保证。

通过AHC，对试片或者实际工件进行焊接，寻找既没有飞溅又可以形成足够熔核的焊接条件。

使用PPS(PPS : Primary Parameter Setting)得到此条件的通电波形。

实际进行焊接时，按照PPS波形，补偿外部干扰，进行通电。

因此，即使工件上有间隙或者分流，不会发生飞溅、且可以形成足够的溶核。

AHC有模式A和模式B，每种控制方法有差别。

・即使电极帽磨损，可以自动补偿电流(模式A)。

・即使板厚发生变化，根据板厚自动调整电流和时间进行控制(模式B)。

2. 安装工作2-1. 各种接线AHC 使用时的安装方法必须先做以下工作。

＜电极间电压检出线＞2-2. 焊枪侧接线电极间电压检出线在焊枪侧实际进行接线时，请注意以下事项。

ahc眼霜哪款效果更好,是黑色还是紫色？

ahc眼霜哪款效果更好，是黑色还是紫色？
我理解您的问题是关于ahc眼霜黑色和紫色哪款好用。

我们需要了解一下ahc品
牌的特点和产品。

ahc是韩国的一个知名护肤品牌，以其高品质的产品和卓越的效
果而受到消费者的喜爱。

在其眼霜系列中，黑色和紫色是两种不同的产品。

先来说说ahc黑色眼霜。

这款眼霜主要针对熟龄肌肤，具有很好的滋养和抗老化
效果。

它含有多种天然植物精华和透明质酸等成分，可以深层滋润肌肤，改善细纹和皱纹，并提亮皮肤。

很多使用过这款眼霜的消费者反馈说它能够有效改善眼部肌肤的干燥和松弛问题，使眼周肌肤更加紧致光滑。

接下来是ahc紫色眼霜。

这款眼霜则更适合年轻人或者眼部肌肤较为敏感的人群。

它含有薰衣*等天然植物提取物，能够舒缓眼部肌肤，减轻眼部疲劳和浮肿。

紫色
眼霜还具有一定的美白效果，能够淡化黑眼圈和减少色素沉着。

到底哪款好用呢？这个问题并没有一个绝对的答案，因为每个人的肌肤状况和需求都不一样。

如果您是属于熟龄肌肤，关注抗老化效果的话，那么可以选择ahc黑
色眼霜。

如果您是年轻人或者眼部肌肤较敏感，希望舒缓眼部疲劳和改善黑眼圈的话，那么可以选择ahc紫色眼霜。

ahc品牌的眼霜都有其独特的特点和适用人群。

根据自己的需求和肌肤状况做出选择才是最重要的。

我们也建议您咨询专业医生或前往专柜试用后再做决定。

祝您找到适合自己的眼霜，并拥有美丽年轻的眼部肌肤！。

AHCU型风冷热泵控制器使用手册2

型风冷热泵模块机组控制器是第三代控制器。

新一代控制器软件上做了很大的改动，进一步提高了智能化程度，运行管理更加具有人性化，除霜更加有效，抗干扰能力更强。

型风冷热泵模块机组其控制器在软件上可分为主模块和子模块而硬件结构完全一样，方便用户使用。

主模块控制器主要控制水泵、压缩机、风机、四通阀、键盘管理、显示器的管理以及输入信号采样及远程通讯，以及各子模块的管理，查询各设备的工作状态、故障分析、报警。

子模块控制器接受主模块的控制命令，完成对压缩机、风机、四通阀的控制，以及输入信号采样，采用485通讯方式，可方便组成现场控制网络。

Do not force the cutter by pressing firmly on it. After cutting is finished, always disconnect the drill from the power supply before removing or adjusting the hole cutter assembly.In cases of cutting on the ground, the rear side of the cutting surface should be raised off the floor, press the drill slowly downwards depending on the revolution speed of the drill. Do not force the cutter by pressing firmly on it. After cutting is finished, always disconnect the drill from the power supply before removing or adjusting the hole cutter assembly.To prolong the service life of this tool, always operate it correctly and clean it after each use with a lightly oiled cloth.1.2.3.4.5.6.Cuts plywood, plasterboard, acrylic sheets and silicon sheets up to a maximum depths of 27mm (1.1”).Drilling on the ground and using the same center point blade on the front and reverse side of the workpiece, allows a maximum cutting depth of up to 52mm (2.05”).Maximum cutting diameter: 254mm (10”)Minimum cutting diameter: 55mm (2.2”)e the protection cowl (11) and the drill (1) to stabilize the cutting point.The protection cowl (11) is injection molded by PC material into one integral part, robust and prevents chips from flying.Compatible with various kinds of drills in different revolution speeds. Cuts safely and rapidly.1.2.3.CUTTING INFORMATIONCUTTINGINSTRUCTIONSFEATURESThe drill, cutting blade, cutter holders and the transverse axle must be fixed tightly and securely with screws while cutting.Adjust the cutting size by confirming that the inside plane surfaces of both the right and left side cutter holders (8) must be aligned with the same graduation and both of the right and left screws (9) must be fixed tightly and securely before you start cutting.I there is any noise or vibration during operation, check whether the screws have loosened.After operation, the bearing (12) and upright axle (2) must be cleaned.1.2.3.4.WARNINGS。
