A Deep Look Into Embedded Technology


Reading time ( words)

In preparation for this month’s magazine, we set up a conference call with the goal of uncovering the challenges and opportunities related to embedded technology. Invited were a handful of the industry’s heavy hitters in the embedded world: Retired technologist and I-Connect007 Contributing Editor Happy Holden, and Ohmega’s Technical Director Daniel Brandler and Design & Test Engineer Manuel Herrera. This informative, comprehensive discussion focuses on the state of embedded materials and components, today and into the future, as well as a variety of promising processes.

Patty Goldman: Gentlemen, thanks for joining us. Some of the things we want to learn are: What’s going on? What’s the latest? Additionally, what are some of the things that you think that your customers want to know? Dan, Ohmega Technology has been doing embedded components for over 30 years. Can you provide an overview of that work?

Dan Brandler: Ohmega Technology primarily makes materials used in embedding resistors, planar resistors, even surface resistors under the solder mask, but mostly it’s a multilayer structure. We electrically deposit a nickel-phosphorous alloy, which is the resistor material. It’s been around since World War II, so it’s a very well established material. We electrically deposit on standard ED copper foil of different levels of roughness, which will be discussed later in the conversation, and we supply that material to either laminators for PCB or microwave applications or to board shops who make their own laminate and PCBs with the embedded resistors.

In some cases, we subcontract laminates out to companies. But our primary business is just applying the resistive copper foil and we’ve been doing that for a long time. We’re not the only ones doing it; there are other alloys out there like Nichrome, but we’re the oldest. About 30−40% of our business is aerospace defense, things like power dividers, microwave applications for satellites, phased array antennas, and microwave absorbers. That didn’t used to be the case, but the majority now for commercial use is mainly for sensor technology, particularly in cell phones. I would guess almost all of you or at least certainly half of you I’m speaking to right now will probably have cellphones with you with our resistors in it. Our resistor material is in the largest American cellphone manufacturer’s products.

The Quest for Perfect Design Data Packages

01/18/2019 | Barry Matties, I-Connect007
There’s an ongoing problem in the PCB industry: fabrication shops are receiving incomplete or inadequate design data packages, leaving manufacturers scrambling to fill in the blanks. For a quick-turn prototype shop like Washington-based Prototron, with over 5,000 customers and up to 60% of orders coming from new customers each month, that can add up to a lot of wasted time and effort just in the quoting stage. Dave Ryder, Prototron president, and Mark Thompson, engineering support, delve into this continuing issue and more.

Rick Almeida Discusses DownStream's Latest News

At the 2018 electronica exhibition in Munich, Rick Almeida, founder of DownStream Technologies, brings Editor Pete Starkey up to speed with the company’s latest news.

Julie Ellis: Communication and Fabrication Knowledge Critical for Designers

11/19/2018 | Andy Shaughnessy, Design007 Magazine
Field Application Engineer Julie Ellis of TTM sees it all: good designs, bad designs, and everything in between. Her classes on proper DFM techniques are always a big draw. She taught at the inaugural AltiumLive in 2017 and was back at this year’s event. I caught up with Julie and asked her to discuss some of the things she covered in class. As she points out, many issues could be eliminated if designers communicated with their fabricators and had a better understanding of how PCBs are manufactured.
