印制板尺寸和公差的最终标准终于到了！替换 IPC-2615是IPC的首批标准（IPC-D-300G）之一，涵盖了 电子封装全面且与其他IPC印制板标准同步，如 IPC-6012A和IPC-2221。该文件包括基本尺寸和公差规则， 位置、轮廓、方向和形状公差，以及详细的几何符号。这个新的 该标准包括100多个新的和修订的插图。对PWB设计师来说非常宝贵， 本文件将帮助制造商和电路板购买者实现最可制造的电路板 设计。

The definitive standard on printed board dimensions and tolerances is finally here! Replacing one of IPC's first standards (IPC-D-300G), IPC-2615 covers dimensioning and tolerancing of electronic packaging comprehensively and in-sync with other IPC printed board standards such as IPC-6012A and IPC-2221. The document includes fundamental dimensioning and tolerancing rules, positional, profile, orientation and form tolerances, and detailed geometric symbology. This new standard encompasses over 100 new and revised illustrations. Invaluable to the PWB designer, this document will help manufacturers and board purchasers achieve the most manufacturable board designs.
