把原理图和PCB复制元件和封装到库的一些技巧（以抄OK6410的底座封装为例） 今天 在飞凌官网下载了OK6410的原理图和PCB，如果想做一块Mini的底板。如何能最快地利用上飞凌原来画好的板，是我想解决的问题。 1、首先，把飞凌官方的底板座复制下来，见下图： 2、切换到PCB库，粘贴（注意，要在编辑区粘贴，不要在PCB　LIBRARY那里粘贴，如果在那里粘贴的话会分开成5个封装的。）效果见下图： 3、现在放大你会发现，那四个底座引脚的名称都是从1到80，这样元件库跟封装是对应不起来的。所以可以想个方法把那四个座的数字前分别加上ABCD。一个一个地改，这不是我风格，呵呵！探索开始了。。。还是直接贴结果吧，过程现在不重要，哈。 在?/display/ADOH/PCB+Inspector+Panel#PCBInspectorPanel-brosba2发现有一段是这样写的： Formula Tab This tab provides for more advanced modification, allowing you to apply a specific expression to the selected string objects. The expression can include any built-in arithmetic operators and functions that apply to strings (found in Pascal). Once again, if you wish to use the current value for the attribute as part of the expression, you will need to make reference to this original value, either by using the full name of the attribute, or by using the exclamation character (the supported substitute for the name of the attribute currently being modified). When using attribute names, if any names contain spaces, these must be replaced by the underscore character. So, for example, use of the?Component Comment?field within a formula should be entered as Component_Comment. Consider for example three selected memory components specified in a design, with designators U1, U3 and U5. You might want to extend the designators of these components by including some indication of their role. Using the addition operator, you could write an expression to add to the existing string value of theName?attribute. This would take the existing (original) string value and concatenate it with a specified new string, as illustrated below:Name + _MEMor, in shortened form:! + _MEMNote that the spaces are optional. When you press?ENTER?the designators of the components will be updated to U1_MEM, U3_MEM and U5_MEM respectively.To illustrate the use of string-based functions consider the Copy function, which can be used to take a portion of an original string and place it within an expressi
