Flying Probe Testers

What is a Flying Probe Tester? 

The flying probe tester is an advanced robotic machine used to test either assembled or bare PCBs for their electrical performance. With several probes mounted on robotic arms, this tester makes accurate measurements of various electrical parameters at specific points on the board. These probes, known as "flying probes," test for open circuits, shorts, capacitance, inductance, impedance, and other key functional parameters. Many systems also feature high-definition cameras to inspect component orientation, polarity, and alignment, ensuring proper placement. If defects are found, the PCB is sent for rework to address them. This testing method is particularly beneficial for low-volume production runs and prototype boards, as the cost and time required for setup and testing are much lower than traditional methods like In-Circuit Testing (ICT).

The Flying Probe Tester is programmed so that the probes systematically reach any point on the PCB surface. As the test program runs, the probes move across the board, making contact with specific test points to take precise measurements. The collected data is processed and compared to reference values in the tester's computer system, determining whether the board passes or fails and providing detailed information about any defects.  

Key parameters of Flying Probe Testers: 

• System Type: Single-sided or double-sided. Single-sided machines test on only one side of the PCB, whereas double-sided machines test on both sides of the PCB. 
  
• Number of Probe Heads: It represents the number of probes the tester has. 
  
• Camera: Some testers have cameras attached to the robotic arms which can be used for board, trace or pin inspection.
  
• Max Board Size: It is the maximum size of the PCB that the tester can handle.
  
• PCB Thickness Compatibility: It is the PCB thickness that can be handled by the tester.
