Or "GERBER" describes the anti welding layer, and the description of the figure is mainly the anti welding part (that is, the cover ink part).Negative (NEGTIVE): GERBER description is a circuit layer, and the description of graphics is mainly copper parts. Or "GERBER" describes the anti welding layer, and the description of the figure is mainly non welding part (i.e., no ink part).Composite chip (COMPOSTIVE): the layers described by GERBER are synthesized from different polar layers.Usually, the excavation layer and the positive layer are superimposed.The polarity of excavation is C, mainly from line protection or additional process information.GERBER data is a file format that can be generated by all PCBCAD systems that can be processed by all optical plotters. The GERBER format is a subset of the EIA standard RS-274D. The extended GERBER format is a superset of EIA standard RS-274D format, also called RS-274X. RS-274X enhances handling of polygon fill, plus and minus combinations, custom D codes, and other functions. It also defines the rules for embedding an aperture table in the GERBER data file.The GERBER format file consists of a series of data blocks (parameters and code). Each block is separated by a block ending (EOB) symbol. The EOB character is usually an asterisk (*). According to the order in the file, the data blocks fall into the following two categories:1 RS-274X parameterDivided into the following groups in sequence:Prompt parameterAS coordinate selectionFS format descriptionMI mirror imageMO unitOF offsetSF scale factorImage parameterIJ image alignmentIN image nameIO image offsetIP image positive and negativeIR image rotationPF drawing film nameAperture parameterAD aperture descriptionAM aperture customLayer parameterKO excavationLN layer namePositive and negative of LP layer SR mobile and replicationmiscIF embedded file2 standard RS-274D codeIncluding a character function code, such as D code, G code, M code, and coordinate data.

That is, where the solder and solder resist are produced, if the area is defined too large, the line or other conductive object near the pad will be exposed to the solder resist. Thus, in the process of processing, the bond plate and its vicinity metal wire are easy to form "bridging", causing short circuit phenomenon. Thus, the "Solder Bridges" phenomenon in production is usually caused by the improper definition of the mask data in the design stage and the CAD system is not found in time. Therefore, it is necessary to detect and repair "Solder Bridges" phenomenon quickly before processing.CAM350 not only can quickly find "Solder Bridge", but also can be repaired. Before processing to realize this function as long as the use of Analysis Find Solder Bridges to open the menu - > "Solder Bridging" dialog box.Tick in the "Top Check/Bottom Check" in front of a small box can choose only to detect surface or bottom detection or at the same time. In the following "Mask, Layer, Check, Against", select the correct layer, note that Soldermask_top corresponds to the Top layer; Soldermask_bottom corresponds to the Bottom layer. In Bridge Distance, enter the minimum tolerance bridge spacing. In the following "Search Area", select "Process Entire Layer" to indicate that the system will detect all layers currently open. If you choose "Window Area to Process", you would like to select a window first, and the system will detect the area of the window. After OK, the system will continue to be tested for some time. If an error is detected, a dialog boxis popped up. OK, the screen will jump to another edit window, and an information display / edit bar appears on the upper right.Here you can see all of the error specific locations, you can click on "All" to show all the errors, or you can select a error in the drop-down box, so you can query the specific location of the error.6.Check DrillThis function item is used to examine various problems in the drilling. For example, the distance between the hole and the hole is reasonable, whether or not there are two holes of the same size or different size in the same position.Analysis Check Drill Alalysis - > Drills, pop-up dialog box."Overlapped Drill Hits" can check whether there are two overlapping vias at the same location. "Coincident Drill Hits (Different Sizes)" can test whether there are two or more vias of the same size in the same location, but these vias are produced by different Tools. "Redundant Drill Hits (Same Size") can check whether or not there are two or more vias of the same size at the same location, but these vias are generated by the same Tool. "Drill, Hole, to, Drill, Hole, Clearance" can test whether the spacing between the holes meets certain rules. Next, select the layer you want to test in the Layers to Analyze.More than 7. of the DFM test the function can produce a report in the Info Report menu - > display test results. Such as Sliver,Report, Solder, Mask, Errors, Report, Silkscreen, Errors, Report, etc., and can be saved as a *.rpt file.If you have run the test function, just want to look at their specific location can be achieved by using Info - Find menu. You can also click directly in the dialog box of a menu item under Analysis.3. Copper Slivers"Copper Slivers" refers to those thin and narrow areas of copper that may easily fall off during production. This feature not only detects the narrow areas of copper deposits, but also the repair / trim function. Before you perform this operation, first open the relevant layers that you need to detect. Analysis - > Copper Slivers "Copper Slivers Detection" will pop up a dialog box.The first input can tolerate the minimum number of copper in the "Find Slivers Less than". In "Processing Control", you can choose "Fix Silvers" to repair the fine copper. Select "Remove Old Slivers" to eliminate the detection results that have been generated, such as "Mask Silvers"". In the following "Search Area", select "Process Entire Layer" to indicate that the system will detect all layers currently open. If you choose "Window Area to Process", you would like to select a window first, and the system will detect the area of the window. OK, detection system will continue to end time, finally pops up a message, if no error will show "Found no new Slivers". If you find errors will pop up an error message box, determine the screen will jump to another edit window. You can see all theexact locations here,You can click on "All" to display all the errors, or you can select a error in the drop down box so that you can query the exact location of the error.4.Mask Slivers"Mask Slivers" refers to those thin and narrow areas which are easily removed in the production process (commonly known as "green" solder barrier). Once the solder is removed, the solder is easily slid into the solder, causing undesirable results. This function can be detected and repaired before production, so as not to cause unnecessary consequences. Analysis, Mask Silvers, Mask Sliver Detection, a pop-up dialog box.The first input can tolerate the minimum number of copper in the "Find Slivers less than". In "Processing Control", you can choose "Fix Slivers" to repair the fine copper. Select "Remove Old Slivers" to cancel the previously detected results, such as "Mask Slivers"". In the following "Search Area", select "Process Entire Layre" to indicate that the system will detect all layers currently open. If you choose "Window Area to Process", you would like to select a window first, and the system will detect all layers currently open. After OK, the system will continue to be tested for a while and finally pop up a tooltip message. If there is no error, "Found no new Slivers" will be displayed". If an error is detected, a false dialog box is popped up. OK, the screen will jump to another edit window, and an information display / edit bar appears on the upper right. Here you can see all of the error specificlocations, you can click on "All" to show all the errors, or you can choose a error in the drop-down box, so you can query the specific location of the error.1., Silk, to, Solder, SpacingThis is the software to automatically test the screen printing layer and the spacing of the solder resist. Analysis Silk to Solder Spacing, "Check Silkscreen" dialog box will pop up.First, select the two layer you want to check, that is, Sildcreen_top/Soldermask_top, select both andSildcreen_bottom/Soldermask_bottom at the same time. Then enter the most tolerable spacing in the Clearance. The best tick in the "Remove Old Silkscreen Errors", to avoid confusion. After OK, the system performs the lookup, and at the bottom of the screen shows the "Silk to Sold Check" on the left: the percentage shown on the right shows a message box for error after execution. After "OK", the screen jumps to these two levels of information, and a display / edit bar is added to the top right of the screen. Here you can see all of the error specific locations, you can click on "All" to show all the errors, or you can choose a error in the drop-down box, so you can query the specific location of the error.2., Solder, Mask, to, Trace, SpacingIn general EDA software, defined as Solder Mask place, in fact, when the board is painted solder place. Where there is no Solder Mask, the solder is stopped when the board is made.In the process of welding solder to avoid disorderly flow caused between "pad lead bridge" short circuit main purpose of solder resist, ensure the quality of the installation, to provide electrical environment for a long time and anti chemical protection, forming printed circuit board coat".This command is when an implementation software automatically checks the line and Sold (solder) pitch function.Analysis Solder Mask to Trace - > Spacing, "Check Solder Mask" will pop up a dialog box.In this dialog, select the Electrical Layer and Solder Mask Layer two layers to check respectively. Select theTop/Soldermask_top layer at the same time, or check the Bottom/Soldermask_Bottom layer at the same time. Then enter the minimum tolerable spacing in the Clearance. The best tick in the "Remove Old Solder Mask Errors", to avoid confusion. After OK, the system performs the lookup. At this time, the bottom of the screen shows the "Solder to Trace Check": the percentage displayed on the right. After the execution, if an error is detected, an error message box will pop up.Similarly, the screen will jump to the two level of information after the confirmation, and a display / edit bar will be added to the top right of the screen. Here you can see all of the error specific locations, you can click on "ALL" to show all the errors, or you can select a error in the drop-down box, so you can query the specific location of the error.。

本页内容准备学习eVC我的第一个项目仅仅通过另一个简单的步骤创建项目同中有异制作一个声音暂时先到这里欢迎回到大家非常熟悉的MSDN Pocket PC 开发中心，Larry Roof 和我将在这里轮流为您讲解日益流行的手持设备的编程技巧。

当Larry 带着他的iPAQ 走在大街上寻找无线Internet 接入时，像我这样明智的人正在一边查收电子邮件，一边坐在本地星巴克舒适的椅子上，空间有Volkswagen Beetle 那么大。

这不是开玩笑—西雅图令人神往的咖啡商场正忙于安装11Mbps 的无线Internet 接入点，这意味着我可以一只手拿着double-tall latte 编写这个特别的专栏，另一只手拿着油炸圈饼，同时感谢Office XP 的语音识别功能。

上个月，老好人Larry 准备使用令人崇拜的Visual BASIC 语言阐述开发过程。

您知道—它更像图形冒险程序，而不是真正的编程语言，它包含可爱的小图片和对话框，您可以将它们拖过屏幕。

这次我们将使用真正的编程语言— C++。

不用担心，我们不会仅停留在简单的“Hello World”层面上。

如果您是一位经验丰富的C++ 编码人员，那么您会非常吃惊：将您现有的知识应用于这个令人兴奋的新平台是多么的容易啊！如果您刚刚起步，或者很少接触，那么您也可能印象深刻：编写您的Pocket PC 应用程序是多么的简单啊！如果您有Windows ®开发经验，那么您可能想知道，这个C++ 版本是否是某种“玩具”语言。

它会提供Win32 ®兼容的API 吗？MFC 如何呢？ATL 如何呢？有什么样的调试支持呢？好的，你们都会受到很好的款待。

eVisual C++ ®不是C++ 的简装版本，它是真正的McCoy。

此外，Pocket PC 操作系统也不是玩具—它是真正专业的操作系统，因此您可以认为其中存在许多Win32 API。

准备工作：（1）安装WM ware虚拟机（2）操作系统：内核2.6的Linux 系统，建议使用Fedora 。

（3）安装软件：asterisk.tar.gz , libpri.tar.gz, zaptel.tar.gz。

路径：\\10.7.1.7\TeamShare\AlexJunkieGrp\TEMP。

（将这三个文件放到Linux 系统的/opt文件夹下。

）（4） SSH终端。

步骤（1）：安装虚拟机（略）步骤（2）：安装fedora 8 操作系统（也可以使用已经安装过的操作系统）安装操作系统 fedora 8（1）最好完全安装。

（2）在安装过程中配置自己的硬盘大小，如果完全安装的话一般4.0G是不够的。

所以请避免安装时引起的很多不必要的麻烦Attention: 保证网络流通，关闭防火墙。
