Board Fixture and Axis Definition:
Figure 7: Board Fixture
The standard board fixture consists of front (1) and rear (2) dovetail rails with adjustable spring clips (3)
attached to them. The rear dovetail rail may be adjusted front to back to allow holding boards (also
called PCB or PWB) of varying depths. To adjust the rear rail, loosen the black knobs at both ends, and
slide the rail forward or backward using one hand on each end. Keep the rear rail parallel to the front
rail for easiest adjustment without binding. For convention, left to right on the machine is called the X-
Axis. The front to back direction is called the Y-Axis. The heater head (4) travels up and down in the
Z-Axis.
