Sunstone Circuits Makes Shift in Strategy, Offerings


Reading time ( words)

Sunstone Circuits, the Oregon-based online vendor of quickturn circuit boards, has recently made a shift in capabilities that will enable a move into the RF and microwave space. At PCB West, I caught up with Sunstone’s David Warren, and we discussed details of this change and how they plan to approach such a competitive marketplace. 

Barry Matties: Just to get started, tell us a little bit about Sunstone and specifically, what you do, David.

David Warren: I'm the sales and business development guy at Sunstone Circuits. I’ve been with the company for seven years now. I’ve spent my entire career in manufacturing management and sales within the electronics industry. The majority of my experience revolved around printed circuit board assembly until coming here in 2010.  We’ve been in business for nearly 45 years. We were the first to pioneer online quoting and ordering of PCBs. PCBExpress.com and PCBPro.com were the first websites that allowed for online quoting and ordering. We also have our own proprietary PCB design and layout software, PCB123, allowing both schematic capture and the design and layout of PCBs.

Matties: You've had that software out for quite a while, but I understand you now have some new offerings coming out?

Warren: Yes. This past year, we’ve gotten into the RF & microwave market. As you know with the Internet of Things, everything's going Bluetooth, RF or microwave. Typically, RF is anything above 100 megahertz, and then microwave would be 2 megahertz and above. It's a totally different animal than your standard FR-4 circuit board.

RF and microwave PCBs have been on our roadmap for quite a while, and earlier this year we jumped into that world with both feet to help some customers out of a bind. This actually has been a great learning experience for us.  We have added equipment, updated processes and added technical resources to help us be successful.  In less than a year we have come a long way in the RF PCB field and now we feel that we have the right recipe to be very competitive with high quality and support.

Matties: If you fast-forward to today, what's the result of all of that?

Warren: Well, we've already exceeded our targets in terms of sales on the RF side of the business for 2016. Like I said, RF and microwave is a different beast—a different material, but Sunstone has the people to make it successful.

Matties: When you talk about RF, are you talking about actually manufacturing RF boards? Because that would be new, compared to what you guys have been doing.

Warren: Correct, we have added customers in the communication, testing and wireless space that require the use of high frequency low loss materials. With these designs, there is a lot tighter dimensional tolerancing for the board and internal routs. Tighter control on line widths, spacing and registration, surface finish requirements, material movement and more.

In With the New at Cadence

08/15/2018 | Andy Shaughnessy, Design007 Magazine
The next generation of PCB designers is coming—slowly, but surely. What will this new group of designers mean for EDA vendors like Cadence Design Systems? Andy Shaughnessy recently interviewed Dan Fernsebner, product marketing group director and a veteran EDA guy, and Bryan LaPointe, lead product engineer and representative of the younger generation. They discussed the next generation of PCB designers, some of the best ways to draw smart young people into this industry, and why the PCB designers of the future may need to have a college degree just to get an interview.

Susy Webb: Training the New Generation of Designers

08/02/2018 | Andy Shaughnessy, Design007 Magazine
For years, I’ve been running into Susy Webb at PCB West, where one of the classes she teaches is PCB design basics. I always ask Susy about the class, especially the attendees’ backgrounds. Over the years, her class has begun drawing more and more degreed engineers, with fewer “traditional” PCB designers attending. I asked Susy to discuss the next generation of PCB designers, some of the trends she’s seeing among new PCB designers, and the need for designers to take charge of their own design training, whether their management agrees or not.

Multi-board Design with Altium’s Ben Jordan

07/25/2018 | I-Connect007 Editorial Team
Not too long ago, historically speaking, most electronic products contained only one PCB. But multi-board designs have become almost ubiquitous over the past decade, and EDA software companies are working to improve and simplify the multi-board design process. Editors Andy Shaughnessy and Stephen Las Marias spoke with Ben Jordan, director of product and persona marketing for Altium, about the company’s multi-board design tools, the challenges that customers face, and the numerous trade-offs that designers must contend with while performing multi-board design.
