FOR STABLE AND SAFE REWORK

COMPONENT PREPARATION, ALIGNMENT AND PLACEMENT

The RD-500III and the RD-500SIII both come standard with the BP-500 Solder Paste Preparation Kit ( stencils are optional ).
The BP-500 allows the user to apply solder paste directly to the balls of the component. This component is then placed in
the Optics Arm where it is picked from the BP-500 and is ready for alignment to the PCB. The Optics Arm and Alignment
software then allow the user to Zoom, Focus ( if auto-focus is disabled ), and split screen for maximum easy in alignment and
placement. Here are the Basic Steps

STEP 1		STEP 2		STEP 3
Place the component in the appropriate stencil		Apply solder or flux paste to the component.		Deploy the Optics Arm and Place the BP-500 with the component against the stop of the Optics Arm.
STEP 4		STEP 5		STEP 6 (Screen Split)
Using the table movement knobs, align the PCB to the component as necessary. If Theta adjustment is required, it can be done via the Theta adjustment knob on the front of the heater head.				For large components where the balls are difficult to distinguish, the screen split function will enlarge and split the view so that only two smaller corner sections can be viewed.

SAFETY FEATURES

The RD-500III and the RD-500SIII share the same set of unique safety features that make operating the machine simple and safe.
These include:

Initialization Check
When the unit is initially powered up, the software will check all the major motion sensor the software will prevent the machine from operating until the problem is fixed and the error is cleared.

Airflow Sensor
There is an airflow sensor on the main input side of the unit that will prevent the machine from runnning if there is insufficient or no airflow into the machine. Also, if the air flow to the machine is stopped during the cycle it will stop the unit from functioning.

Heater Overload Sensor
Should either of the upper or lower air flow heaters see a condition where they are getting full power from more than 60 seconds, the unit will stop the cycle.

Thermo-protector Cutoff Switch
These are two heater cut off switches that are mechanically attached to heating elements. These cutoff switches act as breakers in a condition where the heaters become over heated. If they reach a certain temperature, then they will cut off the power to the heater. The only way that they will work against is if they are manually reset by pusing a button on the cutoff switch.

Heater Head Slip Clutch
The heater head moves up and down using a motor driven belt. This belt has a slip clutch on it so that if the motion is obstructed in anyway, the slip clutch will activate and prevent injury or damage to the board.

Low Strength Optics Arm
The optics arm is also deployed using a motor which drives a belt. The power that is used to deploy the arm is at such a low level that even the slightest obstruction will stop the deployment. However, once the obstruction is removed, the arm will continue its movement
