Flex Circuit Design Primer for Wearable/IoT Device

It’s a brand new ballgame with flex circuitry and wearable/IoT devices, so you have to add to your existing knowhow re conventional PCB design. Today, technology trends are increasingly toward flex circuits or a combination of rigid-flex circuits for wearable/IoT PCB designs. You can say those trends put us on a different footing, so to […]

EETimes: Wearable PCB Designs Require Attention to Fundamentals

In the absence of printed circuit board standards in wearable IoT electronics, hardware developers need to pay close attention to fundamentals. Because of their small size and dimensions, few printed circuit board standards exist for the growing wearable Internet of Things market. Until they emerge, we’ll have to depend on what we have learned about […]

EETimes: 7 Tips for Overcoming PCB Electromagnetic Issues

Faced with the challenges of new materials and new components, PCB designers must also deal with continuing electromagnetic compatibility and interference problems. Electromagnetic compatibility (EMC) and related electromagnetic interference (EMI) are two culprits system design engineers have historically kept a sharp eye on, among their myriad of other problematic areas. In particular, both are hampering […]

Medical Devices Must Go Lead-free

The most pressing issue many designers of medical electronics have in the foreseeable future is how to effectively design lead-free products. It’s difficult to kick long-standing habits associated with designing lead-based products. But designers must learn to do so, because within the next year or so the European Union’s Restriction of Hazardous Substances (RoHS) lead-free […]

Moving up to DDR2 at printed circuit board layout

Designing faster processors is the order of the day in the computing industry. However, processor speeds continue to exceed memory latency improvements. Although CPU speeds double every eighteen months, memory speed takes about ten years to double. This has given rise to the term “memory wall” to describe how overall system performance is bottlenecked by […]
