Flexible PCB Design Considerations

05.22.2013 by Abbie Shoemaker

Flexible circuits are all around us – in cell phones, cameras, and laptops – and also in us – in pacemakers, cochlear implants, and defibrillators. Over the years, as devices have become smaller and wearable and implantable medical devices have become more prevalent, the flex circuit industry has boomed. Key Tech has also been involved in this trend. We’ve designed a number of flex and rigid-flex PCBs for various applications, and along the way we’ve picked up a few tips.

Working with Complicated Disposable to Instrument Interfaces

04.25.2013 by Eric Schneider

Lab on a Chip, Microfluidics, and Sample to Answer are terms we hear a lot when designing medical devices. For years the trend has been to integrate more and more laboratory functions into small disposable chips or cartridges with the ideal goal of being able to perform all the functions from sample preparation to detection in a single disposable on one instrument. This has led the instruments disposable interfaces to be increasingly complex. Sometimes there are hundreds of electrical connections for internal sensors or actuators, multiple heaters for PCR amplification, systems for magnetic bead capture, pressure connections for fluid control, actuators for dispensing stored fluids, and external sensors just to name a few. The complex interfaces required can cause many design challenges, but after working on several of these types of projects over the years we’ve learned there are some ways you can make your life easier, and end up with a better design.

Betascape 2012

2012 marked the third year of Betascape, the annual weekend gathering of artists and technologists (some may say nerds) from the Baltimore area to explore the intersection of their disciplines.

Engineering the Crab Feast

08.01.2012 by Ben Lane

Early in July, Key Tech hosted our annual crab feast on a farm north of Baltimore. This event started more than a decade ago when the company had less than 10 employees, and now hosts nearly 100 employees (current, past, and future), family, friends, clients, and vendors.

Pinhole Camera to Venus

06.29.2012 by Josh Mull

On June 5, Venus passed between the Earth the sun causing a rare celestial event. This event caught some of us at Key Tech by surprise, and at the same time we felt the need to see this event that will not happen again until 2125. As such, we spent part of our afternoon trying to devise ways to stare at the sun without hurting our eyes, and the best option we found was to build ourselves a pinhole camera.

Welcoming a New Generation of 3D Printers

06.06.2012 by Aaron Pearl

Here at Key Tech, we often use physical prototypes in our design process to literally get a feel for the part. While 3D computer models can be helpful, there is simply no substitute for actually holding a part in your hands and feeling it. 3D printing is often a great option for an initial prototype, especially for complex parts that are difficult to machine. Essentially, 3D printers work by printing many thin 2D cross-sections of a part on top of each other, bonding each layer to the previous one as they go. For more complex parts, special support structures may be required to keep the part from falling apart during the printing process, but the process is essentially the same.

“Why Engineering?” We Ask “Why Not?”

Recently I was asked to prepare a 10 min talk about why I became an engineer, what I like about it, and what I do here at Key Tech.
