Spring probes, also known as pogo pins, have become core components in ICT and FCT systems because they create temporary, repeatable electrical contact under thousands or millions of cycles.
What Spring Probes Do
A typical spring probe combines a plunger, barrel and spring. Together they keep contact force stable, reduce intermittent opens and support fixture maintenance over long production runs.
Why They Matter in ICT
Modern electronics density requires accurate contact on increasingly fine pitches. Reliable spring probes help manufacturing teams reduce false failures, improve throughput and preserve fixture uptime.
Key Selection Factors
- Rated current and voltage
- Stroke and recommended working travel
- Tip geometry matched to the pad or via style
- Mechanical lifetime and maintenance interval
Maintenance Best Practices
Periodic cleaning, cycle-based replacement and correct storage conditions extend fixture life and keep contact resistance predictable.
Conclusion
Understanding these fundamentals helps engineers choose probe families that balance accuracy, durability and production efficiency.
