Taking Another Look At ISO 13485

ISO 13485 is about potential risks involved and mitigating them during and after the building of medical products. It is a specific ISO standard serving as a comprehensive management system for the design and manufacture of medical devices. Like other ISO standards, its focus is on continuous improvement in process and quality systems. Also, a […]

Don’t Sabotage Your PCB DFM

Going from a PCB design house to a non-associated PCB assembly house often poses a problem for the OEM customer. Simply put, design-for-manufacturing or DFM is completely neglected. A number of PCB design mis-steps can occur at layout, especially when you have inexperienced designers who have good intentions, but fail to understand the nuances of […]

Catch Up With Micro BGAs

Micro BGAs are proving exceedingly popular these days. These small packages are not only populating conventional PCBs that continue to increase in complexity, but also the smaller circuit boards for IoT and wearable devices. The micro BGA package is more compact than other SMT devices and hence, has a shorter contact length from the device […]

Get On the Right Wavelength for RF

RF circuits are designed to pass signals within a certain band. They use band pass filters to transmit signals in a so-called band of interest. The signal within a range of frequency passes through this band range, and the rest of the frequencies of the signal are filtered. A single band can be very narrow […]

Stay Ahead of Smaller PCBs To Maintain Reliability

OEMs continue to demand greater functionality in smaller portable and handheld products, such as wearables and IoT devices. As a result, a number of attributes are demanded these days for PCBs in smaller mobile technologies. Along with those attributes come a host of challenges in terms of layout, fabrication, and assembly, plus assuring many of […]

Light Up Your LED PCB Projects

LEDs are the light of choice for growing numbers of applications due to their shrinking size, as well as declining cost and longer life. But LEDs pose a host of issues to the PCB layout designer including thermal management challenges. Within thermal management, there are a few other key issues to ponder. Those involve PCB […]

Component Placement More Critical Than Ever

We’re now talking about BGA-packaged components with 4,000 or so leads or balls, 0.3mm pin pitch and below, highly component populated automatic test equipment PCBs, and ever shrinking conventional PCBs and small flex circuits for Internet of Things (IoT) and wearables. That tells you that component placement on these PCBs at the pick and place […]

Check Out Thermal Management Considerations

There are a number of considerations an experienced PCB designer applies for thermal management. However, the key design steps essential for effectively dissipating heat are: Properly distributing analog circuitry throughout the board. Effectively using ground pour on the PCB. Strategically deploying thieving, when possible. Considering a metal core (MC) board, if applicable. Creating more solid […]

Micro BGA Gains Popularity for Wearable/IoT PCBs

With the increasing demands for wearable and Internet of Things (IoT) devices, chipmakers are scrambling to yet pack even more circuitry into even smaller component packaging. The micro ball-grid array (BGA) package is a case in point. Fig. 1 shows micro BGA-packaged devices placed on a flex circuit for a medical electronics application. These tiny […]

Advanced Packaging Reshaping PCB Landscape

Can you imagine component packaging so small you can barely see it. And if you accidentally sneeze while trying to see it, it’s literally blown away forever. You’ll never find it. Active and passive device packaging of those dimensions is what you’ll be dealing with as PCB technology continues to move forward into increasingly smaller […]
