BGA-3500 Series Manual 5/01
Probable Solution:
• Rotate the nozzle lock / release lever fully counterclockwise prior to inserting the nozzle.
• Ensure that the notch or oval hole on the nozzle is indexed so that the notch or oval hole is facing
towards the operator (the front of the machine).
3. Problem: The component will not lift automatically after reflow.
Check:
• Has a “lift” profile been selected?
• Has the lift solenoid been depressed prior to starting the reflow cycle?
• Has the vacuum cup been locked into position so that it is in contact with the component you wish to
remove?
• Has a vacuum cup been inserted onto the vacuum rod?
Probable Solution:
• Ensure that a “lift” profile has been selected, not a “place” profile.
• Depress the lift solenoid prior to starting the reflow cycle.
• Lock the spring loaded Z-Axis on the reflow head so the vacuum cup is in contact with the component to
be removed. The red LED on the reflow arm will illuminate to indicate a vacuum seal. Do not exert exces-
sive pressure or the component may not lift.
• Select the appropriate size vacuum cup for your application and insert onto the vacuum rod.
4. Problem: Operator cannot remember security code and is locked out of the BGA System.
Solution:
• Contact your local Metcal representative or Metcal Applications Engineering for instructions on overriding
and entering a new security code.
5. Problem: When operating with a CSP nozzle in the Placement mode an error “BGA Head Hot” is dis-
played on the computer.
Solution:
• The vacuum pad may be blocking the air path through the nozzle forcing the head to overheat. Remove
the vacuum pad, allow the head to cool and restart the reflow cycle.
