Q4/17 Updates – A good variety of work!

It feels like it has been a busy couple of months here at Unit 3 Compliance with a wide variety of projects coming through the door. Q1/18 is already shaping up to be busy with some really interesting products booked in for pre-compliance testing and some nice meaty problems to get our teeth into. I’m […]

An Important Balance

Here at Unit 3 Compliance, we recognise that the industry we primarily work in, electronics, has environmental consequences caused by the production, use and disposal of electronic products and systems. Many electronic components are highly complex and not easily recyclable. Energy usage of electronic products is massive. Waste electronics, if not disposed of correctly can […]

Have an anechoic Christmas!

The office tree is up! Wishing all the customers, suppliers and friends of Unit 3 Compliance a very happy Christmas and a prosperous New Year. “Oh Christmas tree, oh Christmas tree Your branches grow, Log periodically…”

IoT Security Seminar Report

I attended a really interesting technical conference on IoT security yesterday at the Digital Exchange right here in Bradford (organised by Future Electronics). The main message I took away was that IoT security is achievable but requires a lot of thought up front at the design stage including selection of the primary hardware to enable […]

Case Study: AC Mains Input EMC and Safety Troubleshooting

Many of the customers I deal with are technically savvy and extremely good at designing innovative and clever devices. I’m always learning something new every time I get a different product through the door. Unfortunately it isn’t practical or possible to be good at everything and EMC expertise, especially when it comes to fault finding […]

Not just EMC – we get our hands dirty

More than just a test lab, we are your product design partner. A busy week of EMC testing this week on a variety of products but, as the picture suggests, our usefulness doesn’t just stop at testing. One customer posted a sample of their product for testing with the latest sample of DC motor in. […]

Antenna Miniaturisation

An article just published on Nature Communications covers some interesting and quite exciting developments in antenna miniaturisation.   Overview Electrical antennae rely on being resonant or partly resonant with the electromagnetic wave at the frequency of interest. For a dipole, a length of lambda / 4 is ideal but antennae can be designed with electrical […]

Recent Work: Medical Laboratory Equipment EMC Testing and more

It has been an good couple of weeks here at Unit 3 Compliance with some very interesting products to work on. Firstly, I received confirmation from a previous customerĀ that their product has passed the required EMC certification testing at their accredited laboratory with the modifications that we incorporated during our problem resolution work. This is […]

Brushed DC Motor – EMC Radiated Emissions Problems and Improvements

I’ve been working with a customer whose product had significant broadband radiated emissions throughout the spectrum, helping them with fault finding and improving their EMC performance. Partial information from their certifying test lab appeared to show a regular harmonic series suggesting noise from a digital clock of some kind. However, near field probing with a […]

NFC Antenna Optimisation

We’ve recently been working on optimising an Near Field Communications (NFC) card reader antenna using our skills in wireless integration and antenna design. The customer had an existing system and a new requirement to mount the read antenna at the end of a cable away from the NFC reader mainboard. This involved us working on […]
