Flying Probe test utilizes electro-mechanically controlled tests to get to mechanisms on printed circuit board…. Generally utilized for analog component testing, analog signature analysis, and short/open circuits…visit http://equip-test.com
2. An Overview about the Flying Probe
Equip-test
Flying probes are playing a big part in the electrical and
electronic testing world. These flying probes are mostly used
for testing medium to low volume production, prototypes, and
in boards with accessibility issues. The testing related to flying
probe implements the usage of electro-mechanical controlled
probes that are used for an easy access to components on
printed circuit assemblies (PCAs). These are generally in
experiments and testing related to short circuits, open
circuits, analog signature analysis and analog components.
3. 1. First Generation Flying Probe – availed from mid 1990s
• Provides single sided with flying test probe on the top side only
2. Second Generation Flying Probe - availed from mid 2000s
• Provides double sided with angled probes both on the ends
3. Third Generation Flying Probe
• Provided with four or more flying on top and bottom side
• Incorporated in different technologies like thermal runaway, boundary
scan, etc.
4. Other Flying Probe
• For diagnosing defects one or two sided flying probes are connected
• For testing printed circuit board, bare board flying probes are used

Benefits of using Flying Probes:
• No fixturing is needed, which customize it to be low in cost
• Helps in easing the work with their accurate probing techniques for
those components that cannot be accessed in an ICT fixture
• Has a very fast development cycle
• Better in detecting defects and fault coverage in different test
techniques
From the above mentions context, one can surely get a huge lot of knowledge
about the flying probe. Go through it and enhance knowledge about this small but
very important probe.
