In-Circuit Testing (ICT) is one of the most effective ways to find assembly and component defects before they turn into functional failures. Designed for speed, repeatability, and high coverage, ICT verifies component presence, values, orientation, and basic functionality directly on assembled printed circuit boards.
At Datest, ICT isn’t just about running tests, it’s about building the right test strategy, maximizing coverage, and helping you reduce escapes, rework, and downstream failures.

What We Do

Datest provides full-service In-Circuit Testing, supported by experienced engineers who understand both manufacturing realities and design intent.

Our ICT capabilities include:

Comprehensive PCBA-level testing

Custom test program development

Precision “bed-of-nails” fixture design & fabrication

Design for Testability (DFT) support

Programming services

Engineering collaboration throughout the product lifecycle

Whether you’re ramping production or stabilizing an existing design, we meet you where you are.

Custom ICT Fixtures

Built for your board. Built to last.

Reliable ICT starts with reliable fixturing. Datest designs and builds custom “bed-of-nails” fixtures tailored to your exact PCB layout and production requirements-ensuring repeatable contact, mechanical stability, and long-term performance.

Our fixturing approaches scale with complexity and volume, supporting everything from simple boards to dense, high-pin-count designs.

Why ICT with Datest?

Early Fault Detection & High-Test Coverage

Covers a wide range of defects at the component and board level, ensuring thorough quality control.

Fast & Automated Testing Process

Reduces test time compared to manual probing or functional testing, improving throughput in production lines.

Not Sure What Test You Need?

That’s kind of our thing.

Most customers don’t come to us knowing exactly which test will solve their problem. They come with a failure, a requirement, a deadline, or a part that “just isn’t behaving.”

That’s where Datest comes in.

Understand what’s actually going on

Determine which test methods make sense (and which don’t)

Avoid unnecessary testing, cost, and delays

Build a clear, defensible path forward

No guesswork. No pressure. Just honest guidance from people who do this every day.
