SpletFor example, when SMDs are mounted on a PCB using a completely flat PCB surface as the reference line, the allowable coplanarity value is defined as the tolerance for the maximum gap between the board surface and the multiple contact points of the pins or solder balls. Standoff is a different element that is easily confused with coplanarity. SpletControlled impedance of a PCB transmission line. A PCB transmission line comprises a signal trace and its return path- usually the nearest reference plane(s). If the geometry of the signal trace, its return path, and the material between them is unchanged throughout the length of the trace, then we have a uniform PCB transmission line.
