Scaling USB-C Device Testing: What Every Production Manager Should Know

Faster Testing. Fewer Errors. No Cable Flipping Required.

USB-C is everywhere — powering laptops, phones, tablets, monitors, and more. It’s flexible and powerful, but with that comes complexity. If you’re managing production for USB-C devices, the challenge isn’t the port itself. It’s the testing.

One missed defect can lead to a return, a delay, or damage to your brand. And catching that defect after the product ships? That’s costly.

The real issue isn’t USB-C. It’s the outdated, manual testing methods most teams are still using.

The Real Bottleneck in USB-C Device Production? Manual Testing.

Cut Test Time, Eliminate Errors, and Scale Across Lines — No Cable Flipping Required

If you manage production lines for devices with USB-C ports, the real challenge isn’t the port — it’s the testing.

A single bad port means a return, a delay, or a hit to your metrics. And catching it after the fact? That’s expensive.

So your team tests manually — plugging things in, flipping cables, watching for signs of life.

But manual testing is slow.
It’s inconsistent.
It misses things.
And worst of all, it can’t keep up as you scale.

USB Port Switching for Batch In-Circuit Programming and Testing

Enhancing Production Efficiency with Batch ICP

In device manufacturing, firmware is flashed onto devices using in-circuit programmers (ICPs). automated batch programming can help remove the ICP bottleneck. In this application note, we'll look at how to use USB port switching with Acroname's Industrial USB hubs to boost throughput for batch in-circuit programming and testing.

AUTO DRIVE: The automation of automotive USB-C mobile device testing

The need for USB-C and power delivery ports in automobiles is speeding up, and the auto industry is adapting to the new demands. As the engineer in charge of testing, you’ll need to up your automated validation testing game.

Automotive USB-C Hub Testing with MTM and microFCT

Kentigen, one of Acroname's partners supporting the test market in Europe, used MTM to solve a months-old problem of testing final assemblies for an automative infotainment system. Spoiler: Kentigen used MTM's modularized, miniaturized, and low-cost instrumentation as the heart of its system which enabled them to develop and deploy an automated end-of-line test system for an automotive USB-C hub.

Making wireless test fixtures actually wireless

Create and Deploy Wireless Test Fixtures

One of the benefits of using Acroname's BrainStem/MTM series modules in functional circuit test is being able to create and deploy "wireless" test fixtures - a fixture with no wire-wraps or cables.

Setting up product manufacturing involves many complicated systems and processes. In order to produce millions of devices a month, companies need to massively scale these systems. Yet this scale is in direct conflict with fast product changes and time-to-market for "the next big thing".
