When planning how to successfully bring an electronic product to market, organizations often focus heavily on design innovation, manufacturing readiness, and production scalability. But one element that frequently receives less attention—yet has an enormous impact on long-term success—is the test strategy.

A thoughtful test strategy ensures your product is assembled correctly, performs as intended, and can scale from prototypes to high-volume production without risking recalls, rework, or costly delays. At Circuit Check, we see firsthand how companies benefit when test is included early in the development process—and how challenging things become when it isn’t.

There are several common approaches to functional test station architecture, and why test planning is essential.  Early Design for Test (DFT) decisions pay off throughout the product lifecycle.

Functional Test Station Architecture Options

When designing your test strategy, one of the first decisions you’ll make is how to architect your functional test stations. The right choice depends on product mix, maturity, and production volume. Many organizations ultimately deploy a hybrid approach, combining multiple architectures to meet diverse needs.

Universal Test Stations

A universal test station is built to support a wide mix of devices under test (DUTs). Instead of creating a dedicated station for each new product, a universal platform allows companies to reuse a common test chassis across multiple programs.

A universal test station typically includes:

• A test rack with computer and core instrumentation

• A mass interconnect system

• A family of compatible test fixtures

• Scalable software and reusable templates

For each new DUT, teams simply add a fixture and develop a test software application. Because the hardware and software foundation remains the same, universal stations help companies:

• Reduce capital equipment costs

• Shorten development timelines

• Increase station utilization

• Support high-mix / low-to-medium volume manufacturing efficiently

Circuit Check has developed universal and semi-universal platforms for decades, allowing customers to expand test coverage as product lines grow—without rebuilding infrastructure each time.

Why Test? A Critical Part of Go-To-Market Strategy

Companies of all sizes—from startups to multinational OEMs—focus heavily on accelerating product development and scaling manufacturing. Common questions include:

• How do we bring our product to market as fast as possible?

• How do we scale from prototypes to production?

• Is our manufacturing strategy ready to support projected growth?

While these are essential, another question is equally important:

“Is our test strategy robust enough to ensure our product works as intended, at scale?”

Rushing to market without a strong test plan can lead to:

• Expensive recalls

• Large scrap piles

• Production delays

• Quality escapes

• Damage to brand reputation

We’ve supported customers across industries—including automotive, aerospace, medical devices, defense, semiconductor, telecommunications, and enterprise electronics—each with different priorities and product requirements. But across every industry, the importance of test remains the same.

A fast launch is an advantage…
…but a fast launch that results in field failures becomes a liability.

The Value of Early Design for Test (DFT)

The most successful projects Circuit Check supports have one thing in common:
Test is considered early in the design cycle.

By planning for testability during PCB layout and early prototyping, companies can achieve:

• Higher test coverage

• Fewer production failures

• Lower test development cost

• Faster time to production readiness

• Reduced long-term operational risks

Small layout decisions—such as accessible test points, boundary scan readiness, component spacing, and fixture-friendly connector placement—can significantly streamline downstream testing.
