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.

Fix Inconsistent Serial Port Assignments with USBHub3+

The Problem: Inconsistent Serial Port Assignment for multiple devices

A recurring issue when working with multiple USB-to-serial connections is that the operating system does not consistently assign port names. This is especially painful for end-of-line (EOL) functional test customers who are connecting multiple Devices Under Test (DUTs) at once, since it is important to know which DUT is passing or failing. 

USB-C-Switch for DisplayPort Alt Mode functional test

USB-C ports have to handle a variety of functions including data transfer, power delivery, and DisplayPort (DP) Alt Mode video output.  Device manufacturers need to perform factory End-of-Line (EOL) testing to make sure that their products meet specifications  In this blog post, we'll be looking at how to automate and speed up EOL testing of DisplayPort (DP) Alt Mode with Acroname's USB-C-Switch. 

Mitigating Battery Swell in a Device Lab

Mobile devices are designed to survive crammed into our pockets day-in and day-out; they can even survive toddlers and teenagers for a few months. Yet placing thousands of phones or tablets into server racks can actually be a harder place for these devices to survive long term. The continuous battery charging, high processor usage, and high temperatures present in test labs racks present unique challenges to device longevity since they were not designed for these applications.

Introducing the world’s first industrial programmable USB-C Hub, Power Delivery Analyzer, and Tester

The USBHub3c is designed specifically for mobile device test labs, USB-PD validation testing, USB-C device production testing, end-of-line battery charge, and for testing dual role data (DRD) and dual role power (DRP) devices. Fully programmable, engineers can control USB-PD parameters, connectivity options, real-time measurements, and data.

 

 

Protecting USB devices from Electrostatic Discharge (ESD)

ESD Mitigations with Acroname

The next-generation circuitry in today’s consumer and industrial electronics is smaller, faster, better. Consumers love the innovations. But test engineers are not as enthusiastic. Because that innovation comes with a striking downside: increased susceptibility to electrostatic discharge.

If the USB devices you’re using aren’t built for rugged environments, a catastrophic failure could — and probably will — happen. You’ll have to tell the C-Suite that all your electronic components fried because your ESD mitigations failed.

The 6-R's of Manufacturing Test

When it comes to advanced and cost sensitive electronic products, it remains vital to accurately test these devices during manufacturing and assembly to make sure they provide what the consumer expects and that each and every feature works how it should, right out of the box. The last thing a company needs is for faulty product to reach the hands of hard-won customers. Having disappointed consumers and managing recall related expenses are important problems to be avoided. But at what cost?
