Quick Guide to Acculogic’s Sprint Flying Probe

Where and when to use the Sprint 4510

• Low volume high mix manufacturing
• New product validation – prototype testing
• Repair depot

Advantages of the system

• No fixture required translates into substantial savings
• Quick program development – within hours or a few days (1-2), not weeks
• Easy to apply changes (ECOs) – no fixture, just the program

Types of test performed

• Analog MDA (in-circuit) test – non power-up
• Vectorless digital test (Junction Diode, Capacitive test)
• Power-up: Boundary Scan, some limited digital test (no back drive)
• Automated Optical Inspection

SPRINT’s main features

1 - Linear Surface Motors

• The four heads are on the same high precision platen
• The four heads have the same mechanical characteristics.
• The four probes have the same length and the same angle.
• The four heads can move anywhere on the platen independently.

2 - Alternative head movement

• Four probes requires a very complicated architecture.
• The four probe holders are in two different planes.
• The probes have different angles
• The probes have different lengths
• The movement of the probes in the bottom plane (green mechanism) is limited by the position of the probes in the top plane (yellow mechanism)

3 - Probe Angle (6 degrees)

• Sprint’s probe angle is 182 m or 7 mils more accurate on a board warped 1 mm.
• Sprint’s more vertical probing angle minimizes the frequency of ‘mis-hits’ or ‘slips’ on warped boards.

4 - Large Board Size and built-in Conveyor System

• SPRINT 4510: 20”X24”
• SPRINT 4600: 24”X24”

5 - Powerful and accurate analog measurement system

6 - Power-off digital test

• DeltaScan™ – Junction Diode
• FrameScan™ – Capacitive

7 - Boundary Scan test and programming

• Acculogic is the only flying probe supplier with own its own boundary scan tools
• Much better integration through Flying and Stationary probes
• Fast and reliable – adaptive clocking and none-stop data
• Supports test and device programming

8 - Powerful, easy to use Windows based software

• Integrated CAD translation and automated program generation
• Integrated Boundary Scan and Power-off digital test
• Integrated support for power-on digital and analog test

9 - Additional Capabilities

• Vision system – Automated Optical Inspection
• Power-on digital and analog test
• Digital test channels – up to 256
• Support for stationary probes and probe-plate
