Founded by a team of ex-aerospace engineers, PCL understands that in these sectors, even a minor PCB flaw can have life-threatening consequences—which is why their testing protocols are among the most rigorous in the country.
PCL's specialty is boundary scan testing, a technique ideal for complex PCBs with dense component layouts, such as those found in MRI machines or satellite communication systems. This method uses the JTAG interface to access internal components, allowing engineers to test connections without physical probes—critical for boards where traditional ICT might damage delicate parts. They also offer environmental testing, including temperature cycling (-40°C to 125°C), humidity testing, and salt spray exposure, to ensure PCBs hold up in harsh conditions.
ISO 13485 certified (a must for medical device manufacturers) and RoHS compliant, PCL works with local medical startups and international aerospace firms alike. Their lab is equipped with a Class 7 cleanroom for handling sensitive components, and their team includes two FDA-registered engineers who can guide clients through regulatory submissions. "When we were developing our portable ultrasound device, PCL was with us every step of the way," shared a client from a Cape Town-based medical tech firm. "Their failure analysis report was so detailed that it helped us secure FDA approval on the first try."
For businesses in consumer electronics and telecommunications, speed to market is often as critical as quality—and that's where ElectroVerify Services excels. Located in Durban's Riverhorse Valley Industrial Estate, this family-owned firm has been serving clients like Vodacom and Hisense since 2010, offering a blend of rapid testing turnaround and personalized service that larger labs sometimes lack.
ElectroVerify focuses on two core services: functional testing (to ensure the PCB performs its intended task, like charging a phone or transmitting data) and in-circuit testing (to check individual components for defects). What makes them unique is their "test-as-you-design" approach—they work with clients from the prototype stage, providing feedback on PCB layouts and component selection to make testing faster and more effective later. For startups, this can be a game-changer: one local wearable tech company credits ElectroVerify with cutting their time-to-market by 30% by catching a faulty sensor placement during prototype testing.
