1.首选规格书上的推荐封装来制作；2.参考规格书上的实物尺寸自己设计封

1. The recommended package in the specification is preferred; <br>2. Refer to the actual size in the specification to design the package by yourself: PCB aperture = component foot diameter + 0.3mm, and the diameter of the pad should be designed according to the PCB design rules; <br>3. Pin If the distance is less than 2.5mm, it needs to increase the solder mask screen printing oil treatment; <br>4. Place a 1-pin mark or direction mark on the silk screen layer for directional components;

1. The recommended package on the preferred specification book to make;<br>2. Reference specifications on the physical size of their own design package: PCB aperture - component foot diameter of 0.3mm, pad diameter according to the PCB design rules recommended to design;<br>3. Pin spacing is less than 2.5mm, the need to increase the welding wire printing oil treatment;<br>4. Directional elements in the silk-print layer put 1 foot logo or directional identification;

Design the package by referring to the physical size in the specification: PCB aperture = component pin diameter + 0.3mm, pad diameter is designed according to the PCB design rules;<br>3. If the distance between pins is less than 2.5mm, it is necessary to add resistance wire inking treatment;<br>4. Put one pin mark or direction mark on the screen printing layer for the directional element;
