CAD coordinate system: The coordinate system that a CAD package uses to

describe the orientation and location of integrated circuits

(ICs) on a PCB.

Flexline CAD coordinate system: The standard coordinate system as shown below:

In short, this is a coordinate system on the basis of the

transport direction from “Left to Right” of the Front reference.

Figure B-1 FlexlineCAD Coordinate System

Machine coordinate system: Four difference coordinate systems that any JUKI SMT

machine uses to reference and place ICs on a PCB, namely:

● Transport direction from “Left to Right” of the Front

reference

● Transport direction from “Right to Left” of the Front

reference

● Transport direction from “Left to Right” of the Rear

reference

● Transport direction from “Right to Left” of the Rear

reference

Right-hand rotation rule: Counterclockwise angles are positive and clockwise angles

are negative.

Right-angle coordinate system: The angle between any two of the X, Y, and Z coordinate

axes = 90°.
