PCBM Matrix IPC-7351A LP Wizard 2009 是IPC7351标准的PCB封装（footpoint/cell）生成工具，用于生成符合DFM要求的PCB封装符号。

::::::English Description::::::

The IPC-7351A LP Wizard is a fantastic time saver. It is a land pattern calculator based on the IPC-7351A SMT land pattern standard that allows you to define your own CAD land patterns and offers seamless compatibility with the freely-distributed library documentation.

Advanced features include:
• Graphic display of component features aligned with calculated land pattern
• Compensation variables for fabrication and assembly processes
• Preset operating environments or user defined goals for land pattern toe, heel and side protrusions
• Solder joint analysis calculations
• DRC protection from overlapping lands
• Automatic land pattern name generation
• Save library documentation for later reference/retrieval
• Edit part attribute names and values
• Easily group parts by project

The IPC-7351A LP Wizard allows you to change the Manufacturing Tolerances that determine the pad size, Placement Courtyard Tolerance, PAD Width Round-off, Component Tolerance, Land Pattern Name, and the Solder Joint Analysis. Alternatively, you can simply use the default IPC settings, and save your library documentation for future retrieval.

This product provides the Pick & Place Zero Component Rotation for accurate assembly data. The JEDEC JEP95 publication and the EIA / ANSI 481 specification for tape and reel packaging was used to determine the exact component zero rotation on the assembly tape and reel or tube so that you can build all your CAD library parts in the same zero rotation to provide your vendors with accurate assembly data.

How is the IPC-7351A LP Software Beneficial?
The IPC-7351A LP Software is especially beneficial if you:

spend more time than necessary to match up PCB components with land patterns,
consider the current name of your land pattern to be all the documentation you need to have,
are tired of laying parts on a 1:1 plot of your printed circuit board to verify that the land patterns you’ve selected are the right ones (if you see the difference between 0.1mm and 0.2 mm!)
design your product with its operating environment in mind
want to improve the bottom line by making PCB design more efficient
The IPC-7351A PCB Matrix LP Wizard is the library maintenance tool that will revolutionize the way you work. This software gives you access to options that will allow you to quickly and easily browse your PCB land pattern library to locate, view, construct and verify the mechanics of your PCB library design.
