相关资料表明，发达国家的SMT应用普及率已超过75％，并进一步向高密度组装、立体组装等技术为代表的组装技术领域发展。
组装技术的不断发展必将对组装工艺及相关设备的发展提出新的要求。
如何缩短运行时间、加速转换时间，以及不断地引入具有大量的引脚数量和精细问距的元器件成了如今的贴装设备所面临的严峻挑战。
正因为如此，所以选择合适的贴装设备以满足现如今的应用需要足。
贴片机是用来实现高速、高精度地全自动地贴放元器件的设备，是整个SMT、生产中最关键、最复杂的设备。
贴片机是SMT的生产线中的主要设备，现在，贴片机已从早期的低速机械贴片机发展为高速光学对中贴片机，并向多功能、柔性连接模块化发展。
近年来，新型电子表面贴装技术SMT(Surface Mount Tech-nology)已取代传统的通孔插装技术，并支配电子设备发展，被共识为电子装配技术的革命性变革。
SMT以提高产品可靠性及性能，降低成本为目标，无论是在消费类电子产品，还是在军事尖端电子产品领域中，都将使电子产品发生重大变革。

sonyCD随身听全解
1984年爱迪生发明电声技术之后的100多年里，唱片技术每隔25年就有一次大的技术革新。
从圆筒方式进入圆盘唱片，到电气式唱盘的登场，再进入LP唱片，再从单音进入立体声。
在第100年里，数字音频技术产生了。
1982年8月31日傍晚，日本各大媒体都争相报导“引发音频之梦的数字Player终于上市”、“数字音频时代开幕”等消息。
原来，当天SONY、CBS/SONY、荷兰飞利浦与POLYGRAM四家公司共同举办了CD这个数字录音格式的发布会，并决定从秋季起开始在日本发售。
直径仅仅12cm，利用数字信号录音，只要一个按钮就可执行选曲，能够半永久的使用，CD实现了许多乐迷的梦想。
是年10月1日，SONY推出了第一台CD机CDP-101。
168,000日圆的价格，对一般消费者而言是很难接受的。
不过只要想到里面的技术与开发时间，能做成商品的确是一个奇迹。
进入1983年后，其它公司的CD机也相继上市，销售形势一片大好。
但是，接下来的一年里CD市场却陷于停滞状态。
原来，当时购买CD系统的人是以Hi-Fi发烧友为主，大部分的人依旧偏好已融入生活的LP。
为了拯救这种颓势，SONY公司通用音响事业部的大曾根幸三，拿了一个边长13.4cm 的四方型、约4张CD盒厚度的木盒对属下说：“接下来就尝试做这种CD Player吧。
”每个人听到大曾根的目标后，都不禁的怀疑自己的耳朵是不是听错了，不过他的做事风格就是如此，因此没有人感觉到这是一个艰难的任务。
对于SONY的产品开发人员来说，这个木盒就代表着使用者的需求，就象他们自己说的，“将技术汇总起来后，不知道可不可以做成这种尺寸？看来是不行的。
不过只有这个尺寸，才是能让每个人都欣喜的产品”。
为了让CD达到普及化阶段，SONY公司订定出了这样的方针：“价格不可超过5万日圆，最初虽然会出现赤字，不过日后一定会赚钱的。
”这样的价格是CDP-101那168,000日圆的1/3左右。
实际上，5万日圆的价格，赤字率高达200%。

Therefore, be sure to keep your eyes more then 30 cm apart from the object lens when you check the emission of laser diode.Before Replacing the Optical Pick-Up BlockPlease be sure to check throughly the parameters as par the “Opti-cal Pick-Up Block Checking Procedures” (Part No.: 9-960-027-11) issued separately before replacing the optical pick-up block.Note and specifications required to check are given below.•FOK output : IC601 eg pinWhen checking FOK, remove the lead wire to disc motor.•RF signal P-to-P value : 0.35 - 0.65 Vp-pLaser Diode Checking MethodsDuring normal operation of the equipment, emission of the laser diode is prohibited unless the upper lid is closed while turning ON the S801. (push switch type)The following two checking methods for the laser diode are operable.•Method:Emission of the laser diode is visually checked.1.Open the upper lid.2.With a disc not set, turn on the S801 with a screwdriver having a thin tip as shown in Fig.1.or TAP802 is shorted as shown in Fig.2.Note:Do not push the detection lever strongly, or it may be bentor damaged.3.Press the u button.4.Observing the objective lens, check that the laser diode emits light.When the laser diode does not emit light, automatic power control circuit or optical pickup is faulty.In this operation, the objective lens will move up and down 5times along with inward motion for the focus search.Fig. 1TABLE OF CONTENTS1.

随身听说明书
On charging
• The supplied charging stand can be used only with this unit. No other model can be charged using this stand.
• Remove the AC power adaptor from the wall outlet as soon as possible after the rechargeable battery has been charged. Overcharging may damage the rechargeable battery.
• Use only the supplied charging stand to charge the supplied rechargeable battery.
• Be sure not to short-circuit the battery. When you carry it with you, use the supplied carrying case. If you are not using the case, do not carry the battery with other metallic objects such as keys, rings in your pocket.
Preventing hearing damage Do not use headphones/earphones at high volume. Hearing experts advise against continuous, loud and extended play. If you experience a ringing in your ears, reduce volume or discontinue use.
MP3原理及维修手册
一．Mp3工作原理1. mp3原理图（基于DSP）MP3播放器是利用数字信号处理器DSP（Digital Sign Processer）来完成处理传输和解码MP3文件的任务的。
DSP掌管随身听的数据传输，设备接口控制，文件解码回放等活动。
DSP能够在非常短的时间里完成多种处理任务，而且此过程所消耗的能量极少（这也是它适合于便携式播放器一个显著特点）。
首先将MP3歌曲文件从内存中取出并读取存储器上的信号→到解码芯片对信号进行解码→通过数模转换器将解出来的数字信号转换成模拟信号→再把转换后的模拟音频放大→低通滤波后到耳机输出口，输出后就是我们所听到的音乐了。

MP3随身听工作原理大揭秘
MP3随身听工作原理大揭秘如果您因为对MP3 Player好奇而拆开一个MP3随身听来看看的话（小心没保修了），就可以清晰地看到：里面没有机械结构，你只会发现里面有好多块贴片IC。
也正是这个原因，所以MP3随身听的体积可以做得那么小。
由于MP3随身听在播放过程中的信号流程完全没有涉及机械的运动，所以不会像CD、MD这类随身听那样会因为光头受到外界震动而发生跳音现象，更不会像磁带随身听那样要有传动机械而出现绞带现象。
所以一般来说只要你的储存卡没有问题，在正常情况下MP3随身听在播放时绝不会出现跳音等现象。
另外，由于机体没有机械式运作部件，所以MP3随身听的耗电量没有CD、磁带等随身听大，而相信以后其芯片的技术越来越成熟后，其播放时间将会得到很大的提高，所以在这方面MP3随身听还有比较大的潜力！今天想和大家谈谈MP3随身听的工作原理。
其实和MD机、CD机等类似，MP3 Player 同样也是把贮存卡上的数子信号送到解码芯片进行解码，只不过MP3随身听读取存贮卡上的信号并不是使用光头或磁头之类的机械部件。
一般的工作的流程是这样的：读取贮体上的信号-→到解码芯片对信号进行解码-→通过数模转换器将解出来的数字信号转换成模拟信号-→再把转换后的模拟音频放大-→低通滤波后到耳机输出口。
想比较直观地看看MP3的内部结构，可以参看以下三篇文章：MP3的整机设计方案有数种，主要有单芯片和双芯片之分。
这里给大家说明一下单芯片与双芯片是怎么回事：双芯片是控制部分为一片集成电路、MP3解码运算部分为一片集成电路；单芯片是控制部分、MP3解码运算部分都集成在一片集成电路里面的芯片。
在2002年初的时候单芯片的方案以ST、EP的芯片为代表，双芯片主要以Sunplus的芯片为代表。
双芯在推出时间上比单芯片早一两年左右。
ST的芯片主要应用于三星系列产品中，它的特点是稳定，成熟。
但价格较高、而且没有录音、复读的功能，在这点上不能满足我们的要求。
