The Challenge: More Channels, Less Space
As semiconductor devices become more complex, automated test equipment (ATE) and instrumentation platforms are being asked to support more channels within increasingly constrained footprints.
But increasing density introduces new design challenges:
- PCB routing constraints
- Crosstalk between adjacent channels
- Parasitic capacitance
- Signal integrity degradation
- Long-term reliability concerns
The question isn’t simply how to add more channels.
It’s about how to maintain measurement accuracy while scaling the architecture.

Balancing High-Density Design Trade-offs
Hidden Trade-off #1: Crosstalk
As switching channels move closer together, unintended signal coupling can affect test performance.
The result can include:
- Increased noise
- Measurement errors
- Reduced repeatability
- Lower test confidence
In high-density analog and mixed-signal systems, controlling crosstalk becomes critical to maintaining signal integrity.
Hidden Trade-off #2: Capacitance
As channel density rises, parasitic capacitance becomes increasingly difficult to manage.
Even small increases can impact:
- Signal fidelity
- Switching performance
- Analog accuracy
- Mixed-signal measurements
The most successful test architectures address capacitance early in the design process, before it becomes a validation issue.
Engineering Insight
As channel density increases, design challenges shift from mechanical constraints to electrical performance. Relay footprint, PCB layout, capacitance, and signal routing must be optimised together to preserve measurement accuracy.

Design the Architecture, Not Just the Relay
High-density switching requires balancing multiple design priorities simultaneously:
What Engineers Want
- Higher channel density
- Smaller PCB footprint
What Must Be Preserved
- Signal integrity
- Measurement accuracy
- Long-term reliability
Successful switching systems aren’t built around a single component; they’re optimised across the entire signal path.

High-Density Switching by Design
When PCB space becomes the limiting factor, relay footprint and architecture become increasingly important.
The ASR Series features a narrow 10 mm SIL package, 47% shorter than traditional SIL relays, allowing engineers to increase channel density while maintaining low parasitics and reliable signal routing in analog and mixed-signal ATE environments.
