Altium component clearance Minimum Clearance - the value for the minimum clearance required. Discover features you didn't know existed and get the most out of those you already know about. How on earth are we supposed to fit 100 components onto a board no larger than a quarter?! This may be a bit of an exaggeration, but the fact remains; the issues of PCB edge clearance are becoming more and more relevant. All rules are resolved by If the physical component has been defined using 3D body objects or imported STEP models, three-dimensional component clearance checking can be performed. To set a single clearance value for all possible object pairings, simply set the required value for the Minimum Clearance constraint. Perhaps the greatest strength of the 3D PCB editor is the ability to perform 3D collision testing. Component clearance is calculated using accurate 3D meshing to define shape and contour for the component through its associated 3D body objects. Conversely, when a different clearance value is entered for one or more object pairings in the matrix, the Minimum Clearance constraint will change to N/A, to reflect that a single clearance value is not To match the legacy behavior of the old Silkscreen Over Component Pads rule, found in releases of the software prior to Altium Designer 13. This page details the PCB Editor's Clearance design rule - which defines the minimum clearance allowed between any two primitive objects on a copper layer. Name - the name of the component model. High voltage/high current designs carry safety requirements that need to be met by designers. 25 mm between all objects is suitable. Add Component Clearance design rules to check for collisions between components that include 3D body objects in the X, Y and Z planes. Open the PCB Rules and Constraints Editor dialog.

The Align Horizontal Centers / Align Vertical Centers command enables you to place selected objects in a single column/row, aligned by These routines use the 3D body (if there is one) or the copper and silk primitives to identify an object's clearance. 3D mechanical models can sometimes be sourced from the component manufacturer. Before you know it, it’s back to the drawing board. Returns Component Clearance Rule objects. Conversely, when a different clearance value is entered for one or more object pairings in the matrix, the Minimum Clearance constraint will change to N/A, to reflect that a single clearance value is not Ignore Pad to Pad Clearances within a footprint - toggle this option on/off to specify whether clearances between pads in the same component footprint are ignored. or the copper and silk primitives to identify an object's clearance. If a component has a component body, then the clearance is applied to the component body. The component clearance rule verifies that all 3D bodies and models within the design adhere to the constraints you have defined.
