Introduction

随着人们生活水平的提高，计算机（俗称电脑）已经非常普及，维修量也随之增大，越来越多的人进入计算机维修行业，其中不乏零基础学者和初学者。针对这些人群的学习书籍市场上也有不少，但多数内容不完整，也不够深入，知识面很零散（比如，你想学习示波器操作，得从市面上多本书中才能找到完整的操作方法；或者想学习笔记本维修基础，也得从多本书籍中寻找答案），而且其中有很多知识点是从纯理论角度讲解，不符合实际维修需要，所以想从目前市面上的书籍中学到真正的技术，不是一件容易的事，既浪费时间和金钱，又消磨了初学者的信心。
科学技术的不断创新，给计算机维修行业带来了难度不断提升的挑战。维修从业者需要不断地去学习新知识、新技术才能适应这个行业。计算机维修行业发展到今天，维修人员仅凭维修经验无法持续适应这个发展趋势，所以要不断地丰富基础知识、学习新的技术，以及更多的维修工具使用。
目前整个计算机维修行业已经进入巅峰，维修技术也越来越深入，使用数字示波器维修计算机主板电路是必然趋势，因为使用示波器可以非常直观、非常精确地判断电路故障，在维修中提高了工作效率和维修成本。但是会使用示波器、真正掌握示波器使用要领的人并不多，他们将示波器的使用方法视为看家本领，更不愿外传。再就是BGA返修台的操作方法，所以现在很多计算机维修人员非常羡慕那些会使用示波器修计算机的人和会操作BGA机器的人。目前市面上很少有书籍详细介绍过示波器在计算机电路维修中的应用以及BGA返修台的操作方法。本书完整地介绍了示波器在计算机维修中的多种使用方法和BGA返修台操作方法，利用实测的实例波形图片分析计算机维修中的常见波形和故障波形，让您充分掌握示波器的使用方法，实拍BGA操作图片配合详细文字说明，深入讲解BGA操作方法，弥补图书市场上的这片空白（示波器在计算机维修中的应用、BGA返修台操作）。
本书是以迅维培训中心实地计算机维修基础教材为基础编写的，是迅维培训中心的教学精华本书主要由黄鑫船编写，参与编写的还有孙景轩、杨斌、余振中、赵中秋、李金花、苏友新、范涛、李盛林、李向阳、张树飞、王金奎、徐海钊、朱小文、覃家盛和刘小南。本书结构合理，层次清晰，从电子元器件的特性与工作原理开始，详细介绍了电子电路基础、主板维修基础、笔记本电脑维修基础、显示器维修基础、系统软件安装、各种计算机维修工具使用方法；重点讲解示波器在电路维修中的使用方法，配合大量的电路截图，图文说明，可以使读者很方便地学会计算机维修和示波器操作。
本书附赠光盘中含有如下视频。
笔记本电脑焊接视频
1．EC芯片的拆焊
2．拆黑胶
3．补线
示波器使用视频
1．示波器的基础知识与泰克示波器的设置方法
2．PWM波形讲解
3．笔记本电脑常见波形讲解
4．普源示波器的简单使用方法与示波器在PWM电路中的应用
5．笔记本电脑维修之泰克示波器抓掉电维修实例
手机焊接视频
1．手机尾插的焊接
2．苹果手机塑料件的焊接
3．苹果手机WiFi芯片的撬胶
4．苹果手机双层CPU的撬胶
为了便于读者阅读，本书部分电路图仍采用原图，未按照国标重画。
