验证
根据该零件的样式指南和数据表，三位独立的电子工程专家创建了：
- 3 个版本的符号和 2D 封装
- 1 个版本的 3D STEP 模型（STEP 格式 AP-214）
- 制造商调色板配置
所有创建的库文件都与图层映射无关，可轻松映射到设计中。
然后通过以下检查对创建的符号和封装进行比较：
符号
自动检查
- 零件编号
- 关键参数
- 包装代码
- 引脚名称/编号
- 引脚类型
手动检查
- 根据样式指南整理引脚
封装
自动检查
- IPC 标准
- 丝印间隙
- Courtyard 超额
- 包装外形
- 极性标记
- 焊盘尺寸和位置验证
3D STEP 模型
手动检查
- 尺寸验证
- 调色板合规性
- 格式合规性
- 将方向映射到 2D 封装
- 2D 封装位置验证
进行最终验证过程：
如果符号和封装匹配：零件已验证为 ECAD 就绪
如果符号和封装不匹配：高级电子工程师将审查所有差异，确保零件符合样式指南和数据表要求
