This dissertation consists of three parts: First, we introduce AOI technology applied to the PCB inspection and its development, especially on the PCB solder joint inspection technology.

本文的主要分为三个部分：首先，介绍了用于印刷电路板检测的自动光学检测技术及其发展，特别论述了印刷电路板中焊点的检测技术的重要意义。

The method (700) and circuit board panel (600) of the present invention substantially eliminate assembly-line delamination and sagging for circuit board manufacturing.

本发明的方法（700）和电路板板料（600），在电路板制造中基本上消除了装配线的脱层和下垂。

The circuit board surface one that is at this time is flat, there is no mark to be recognize, have to beat in the circuit board surface for the sake of the convenience of management track and creation up argue to see code by with recognize.

此时的电路板表面一片平坦，没有任何记号可辨认，为了管理追踪及制作的便利性，必须在电路板表面打上辩视码藉以辨识。

S98ZKA0336 VCD UP-GRADING CIRCUIT BOARD FOR A CD PLAYER OR CD-ROM 获证 US 发明 08/815309 5926606 2017/3/9 540,000 Nuvoton 让与 A VCD up-grading circuit board for a CD player or CD-ROM includes an MPEGdecoder, a microprocessor, a DRAM, an audio digital/analog converter, a TV encoder and a synchronous clock generator. The VCD up-grading circuit board for a CD player or CD-ROM is attached to the CD player or CD-ROM to allow the CD player or CD-ROM to play a VCD without additional connection between the VCD up-grading circuit board and the CD player.

S98ZKA0335 自动产生及校正系统同步时钟之影音光碟机升级板获证 TW 发明 86101019 90406 2017/1/29 460，000 Nuvoton 让与本发明系关於一种自动产生及校正系统同步时钟之影音光碟机升级板，尤指一种可附加於CD播放机内而升级为影音光碟播放机之升级用的电路板，此升级电路板为可解决传统升级电路与CD播放机之间同步讯号连接之不便性、易产生干扰与更改CD播放机原有线路所衍生之各项缺陷下，而为一种无需於其间额外连接同步时钟讯号，而在升级板上内建一同步时钟产生器，以随时监视CD播放机与MPEG解码器之左右声道取样时钟讯号之相位差而立即补正，即可达到令两者完全同步者。

Solid carbide tungsten fishtail drill is suitable for pcb flexible foil clad laminate,used for target machine drilling,the features of pcb fishtail drill are thin and flexible plate,it's structure and cutting methods are different with normal pcb drill bits.its two main cutting edge is concave and formed 100degree angle,in order to distinguish with PCB drill,named fishtail drill.fishtail drill cuts beginning of circular drill.concave along the main cutting edge to cut,chip is just two much fine filament.cuttingis falling off naturally,in order to be processed without burrformation by pcb surface.

整体硬质合金鱼尾钻适合印制电路板行业加工挠性覆箔板，为打靶机钻孔用。鱼尾钻所加工的印制电路板特性是薄板、带柔性、这样就决定了它的结构和切削方式与一般PCB钻不一样，它的两主切削刃是内凹的，两主切削刃形成100度的夹角，为了与PCB钻区别，就叫它鱼尾名。鱼尾钻切削时从我圆处钻尖开始，沿着内凹的主切削刃切削，切屑只是两条极细丝状切削，整个切削自然剥落，从而被加工印制板表面平整无毛刺。

The first circuit board is provided with a first noncircular contraposition hole; while the second circuit board is provided with a second noncircular contraposition hole which is corresponding to the first noncircular contraposition.

第一电路板上具有一第一非圆形对位孔，第二电路板具有对应于该第一非圆形对位孔的一第二非圆形对位孔。

When the first circuit board and the second circuit board are electrically superimposed, the first noncircular contraposition hole and the second noncircular contraposition hole are superimposed substantially.

第一电路板与第二电路板电性迭合时，第一非圆形对位孔及第二非圆形对位孔实质上重叠。

The hardware of this system consists of antenna array, Doppler direction finder, system controller and display. The software-work mode controller, data processing and angle display.

整套系统的硬件部分包括天线阵、多普勒无线电测向仪、控制电路板和显示电路板，软件部分包括工作模式控制部分、数据处理部分和角度显示部分。

I didn't lay out the computer PCB, but I did lay out a PCB for a floppy disk controller that I had designed.

我没有列出的计算机电路板，但我并奠定了印刷电路板的软盘控制器，我已设计。

I didn＊t lay out the computer PCB, but I did lay out a PCB for a floppy disk controller that I had designed.

我不*吨奠定了计算机电路板，但我奠定了印刷电路板的软盘控制器，我已设计。

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。
