What is Coordinate Tolerance
Coordinate tolerance specifies the allowable variation in the position of a hole or feature on a printed circuit board, applying tolerances directly to linear and angular dimensions, resulting in a rectangular area that represents the acceptable range of variation.
When using Coordinate Tolerance, the X and Y coordinates, as well as any angular dimensions, are considered when determining the allowable deviation from the nominal position. This deviation forms a rectangular zone within which the hole or feature can be located. Defining the tolerance in this way provides a clear and defined range of acceptable positions for the hole or feature, ensuring that it falls within the specified tolerance.
This method of tolerancing hole locations allows for precise control over the position of features on the PCB, ensuring accurate alignment and proper functionality during assembly and operation. It is an essential aspect of PCB design, providing a standardized and reliable approach to specifying and verifying the position of holes and features.
