How Toward Helped Keysight Technologies Shrink Relay Size by 82%
A High-Density Miniature Relay Success Story
As ICT and ATE systems continue to shrink while demanding higher channel densities, Toward Technologies partnered with Keysight Technologies to develop a custom miniature reed relay that reduces size by 82%, enabling greater performance in compact test environments. This award-winning collaboration showcases how innovations in multi-channel relay design can drive next-generation ICT testing solutions.
Customer Challenge: Miniaturization Without Compromise
Keysight Technologies approached Toward with a critical engineering challenge:
How can we shrink our existing SIP reed relay footprint without sacrificing performance or contact reliability?
Their ICT test systems were evolving to support more channels in tighter spaces, and the existing relay package had reached its physical limits.
To achieve their goals, we needed to:
- Prevent magnetic coupling between densely packed reed switches
- Maintain ultra-low and consistent contact resistance across all channels
- Develop a relay design compatible with mass production and long-term stability
Toward's Solution: Custom Vertical Multi-Channel Relay Design
Instead of simply shrinking the existing SIP package, we reinvented the structure entirely.
- Vertical stacking architecture: Allowed multiple reed switches to be integrated into one compact unit
- 82% space reduction per channel: Freed up valuable PCB space in Keysight’s testers
- Magnetic simulation & field isolation: Ensured each switch activated independently and reliably
- Precision contact control: Enabled software compensation for resistance variation
- Customized tooling for scalable manufacturing: Delivered consistent quality at volume
Results & Recognition
- Achieved 82% reduction in surface area per relay channel
- Enabled higher-density ICT and ATE system layouts
- Strengthened Toward’s expertise in custom relay innovation
- Recognized by Keysight with the 2018 Supplier Day Award for outstanding technical support, quality, and collaboration
