Electronics Product Development: 3 Tips for Detecting Touch Controller Failures

2018-10-09T10:41:19+00:00

In electronics product development, touchscreens can be difficult to stress test; and whilst there are several sophisticated systems available for touchscreen stress testing, there are other ways to get the job done – like a low-tech approach… For example, take a look at this rig built from a child’s toy.  Our engineer built it as part of the debug process to try to fix a failed touchscreen unit. Thanks to our brightly-coloured debugger, we discovered that the touchscreen controller chip itself was unreliable.  The rig kept tapping the screen over and over and over again.   However, what the debug process uncovered was that it took slightly more than a mere tap-tap-tap motion to uncover the bug.  So: Tap-tap-tap motion = unit functioning normally. Tap-slide-and-up motion (closer to an actual [...]

Saving time and money on testing embedded hardware

Putting design and production tests in their place Recent high-profile product recalls and failures have shown that even the most experienced and well-funded company can suffer from the limitations of product testing when testing embedded hardware. A product goes through two fundamental types of test. The first is of the design itself and the second is production testing of a product. These two categories have different aims and this article sets out to explore the differences. Increasing pressure on timescales and the relentless pace of new technology introductions can pressurise companies to reduce design testing to a minimum. Conversely, production testing can be over-engineered to no great effect, resulting in increased production costs and a false sense of security, with testing of a design carried out in production, rather [...]
