PCB layout design grid set tips

Posted on December 13, 2017 by G

Design in different stages need to set different points, in the layout stage can be used to carry large grid layout of the components. For IC, non-locating connectors and other large components, you can use the 50 ~ 100mil grid accuracy of the layout, and for passive components such as small capacitors and inductors, the use of 25mil grid layout. The precision of the large grid facilitates the alignment and layout of the components.
