Getting a MEMS switch to work is a major milestone.
But it is not the finish line.
The real question is whether you can prove that switch is reliable across every device, every wafer, and every shipment. Not in a lab demonstration. Not on a single characterized part. Across everything that leaves the factory and goes into a customer system.
That question shaped how Cenfire was built from the beginning.
Why MEMS Switch Reliability Is Harder to Prove Than It Looks
If you are qualifying switches for semiconductor test hardware, load boards, DIB boards, probe cards, aerospace and defense systems, industrial power platforms, or high reliability electronics, initial performance data is not enough.
You need confidence that every part delivered into your system has been tested against the right reliability indicators. Not a sample. Not a characterization lot. Every device.
That is a harder problem than it sounds for a MEMS switch technology.
For transistors, the industry has decades of qualification standards, reliability models, and acceleration methods. JEDEC standards provide a roadmap. Reliability engineers know which tests to run, which models to apply, and which failure modes to screen against. The infrastructure for proving transistor reliability has been built and refined over fifty years of production experience.
For MEMS switches, that infrastructure is far less mature.
There is no simple JEDEC style roadmap that tells you exactly how to predict every reliability failure mode for a galvanic MEMS switch. The failure mechanisms are different. The material systems are different. The operating conditions that drive degradation are different. Consequently, the tools and methods that work for transistors do not map cleanly onto a MEMS switching device.
That creates a real and practical challenge for anyone qualifying MEMS switch technology for production deployment.
The Questions Every Engineer Should Be Asking
Getting a MEMS switch to pass initial characterization is only the first step. The harder questions come after that.
How do you know the device will continue switching reliably over its intended service life? How do you identify parts that may fail early before they reach the customer? How do you ensure that every device leaving production has been screened against the right reliability indicators and not just checked against a basic pass fail threshold?
For a MEMS switch, answering those questions requires more than a standard production test. It requires a scalable way to measure device behavior, detect reliability signatures, and build confidence across devices, wafers, and production lots simultaneously.
Without that capability, reliability becomes a claim rather than a measured property. A claim backed by demonstration data on a handful of parts is not the same as confidence built from screening thousands of devices through a production flow designed to catch early failure indicators before shipment.
Why Cenfire Treats Test as Part of the Product Architecture
At Cenfire, test is not a final checkpoint at the end of the production line. Test is part of the product architecture.
For a new MEMS switch technology entering production, reliability cannot be assumed from a generic standard or verified with a slow one device at a time lab setup. It has to be engineered into the production flow from the start. That means identifying the right electrical signatures that correlate with long term reliability, measuring them quickly enough to be practical at volume, and screening devices in a way that scales as production ramps.
That philosophy drove one of the first investments Cenfire made before the company started shipping product.
We knew that building a better switch would not be enough. Without a scalable way to test, screen, and qualify the product across wafers and production lots, the technology could not become a real production platform regardless of how well the device performed in characterization. So Cenfire built the test infrastructure alongside the device itself.
The Athena Test Architecture
The available test solutions in the market did not provide the combination of speed, resolution, parallelism, and cost structure required for scalable MEMS switch screening at production volumes.
So Cenfire developed its own.
Cenfire built a custom test architecture using FPGA based control with integrated ADCs. That combination allows the system to capture fast device behavior, monitor proprietary reliability signatures, and test many devices in parallel within the same test pass.
Today the architecture supports testing more than 100 devices per wafer step, or more than 100 switches in parallel depending on configuration.
That parallelism is critical for several reasons. It allows Cenfire to collect more reliability data per production lot, build stronger reliability models from real production devices rather than characterized samples, screen more devices against reliability indicators without adding proportional test time, and reduce the cost of test as production volumes increase.
The result is a test system that scales with the product rather than becoming a bottleneck as volume grows.
What Proprietary Test Infrastructure Actually Delivers
Building the test infrastructure alongside the device gives Cenfire capabilities that matter directly to customers qualifying the technology for production deployment.
Cenfire develops its own reliability database from real production data rather than extrapolating from a small characterization sample. That database informs internal guard bands that reflect actual device behavior across wafers and lots rather than theoretical models applied to a new technology without production history behind them.
Early failure indicators that would be invisible to a basic pass fail test become detectable through the proprietary electrical signatures the system monitors. Devices that would pass a simple functional screen but carry reliability risk get caught before shipment.
And as production data accumulates, the reliability models improve. Each production lot adds to the database. Each wafer contributes to a clearer picture of device behavior across the population. Over time, that data becomes a durable asset that supports customer qualification activities, accelerated life testing, and long term reliability commitments.
Reliability Is a System Not a Claim
For a MEMS switch to matter in production electronics, it cannot only work in a demonstration. It has to work repeatedly across every device, every wafer, and every shipment. It has to be screened consistently against the right indicators. And it has to leave the factory with real data behind it rather than a characterization report from a handful of parts.
That is why product testing has been central to Cenfire from the beginning.
Reliability is not a claim. It is a system. And building that system required investing in test infrastructure before the product was ready to ship, not after.
If you are evaluating next generation switching technology for a production application, do not only ask whether the device works in demonstration conditions. Ask how every device is tested. Ask how reliability is screened across the production population. Ask how the supplier knows which parts are ready to ship and which are not.
That is where Cenfire has done the hard work.
