立创商城PCB封装库 V1.01 for Altium Designer

在公司工作多年，积攒下来的相对较全面的PCB封装库，一共450M，包含有三维模型，有LCD、STC单片机、STM32单片机、常用芯片、电池、电感、电容、电阻、二极管、光电器件、继电器、接插件、晶体管、晶振、开关、声器件、整流桥、其他等

PCB封装国际标准。做高级PCB的人肯定需要 IPC-7351标准覆盖所有类型的无源及有源器件件的焊盘图形设计，包括电阻器、电容器、MELFS、TSSOPS、QFPS、球形阵列封装、方形扁平无引脚封装、小外形无引线封装等。IPC-7351为每个元件提供了三个焊盘图形几何形状，即高元件密度、中等元件密度、低元件密度，对应的PCB Libraries’ IPC-7351 LP Viewer软件中对应的CAD data库分别是SMM/SMN/SML，就是各个库中对应的相同的封装的焊盘尺寸不一样： 高元件密度：焊盘最小。 中等元件密度：焊盘一般。 低元件密度：焊盘最大情况，最牢固
