DownStream Takes on Data Documentation Management


Reading time ( words)

Most PCB designers love their jobs. But designers will also tell you that as much as they enjoy laying out the board, they dislike the final data documentation step, which often involves various formats, including handwritten notes. Enter DownStream Technologies, a company founded 14 years ago to address the challenges related to post-processing the design. Senior Product Marketing Manager Mark Gallant recently discussed the company’s efforts to take the pain out of data documentation, even as data becomes more complex.

Andy Shaughnessy: Why don’t you start out by giving us a little background about DownStream.

Mark Gallant: DownStream Technologies was founded in January 2002 by former PADS Software executives who acquired the assets of Advanced CAM Technologies—products with the brand name CAM350—from Innoveda prior to its acquisition by Mentor Graphics. The newly formed executive team chose the name DownStream Technologies to reflect their goal of delivering technology focused on the “downstream” phase of the PCB design process. Specifically, it’s technology to help bridge the chasm between PCB design and PCB manufacturing domains.

At the time of DownStream’s founding, the predominant method of transitioning a PCB design to manufacturing involved post-processing a design to extract multiple files. Each file was independent of the other in format and content, and disjointed from the original design from which they were derived. What we call the “traditional” process for handoff to manufacturing worked well enough to take us from the days of PCB design by light table up to the start of the 21st century. However, as technology continued to evolve in complexity and market windows to profitability continued to shrink, the traditional process led to higher costs, lower quality and ultimately delayed time to market.

Our founders believe the transition from virtual design to the manufacture of the physical product could be, and should be, improved. We observed this trend in several of our early adopter customers—organizations that were the first to implement new technologies and processes which, once proved out, led to adoption by the rest of the market. To reduce manufacturing delays, these early adopters educated themselves on the PCB manufacturing process. Their newfound knowledge led them to introduce DFM analysis and single file design exchange into their new product introduction process. This revised approach, rather than the “hand it over the wall and hope” method, resulted in significant time-to-market gains. Fundamentally, they were shifting their attention from “upstream” processes to refocus on “downstream” processes, shifting from how a design is created to how it is to be manufactured. The trend of refocusing on manufacturing and a belief that DFM tools and singular design exchange files were evolving from “nice to do” to “must do” was the catalyst for the creation of DownStream. Since our start we have introduced a full suite of DFM analysis, PCB documentation, and assembly panel design tools.

Shaughnessy: What are your customers’ biggest demands when it comes to their new product design process?

 

Gallant: In the world of electronic product development, and specifically PCB design, the demand is clear: a successful, error-free transition from design to manufacturing. Many of our customers believe the transition process from design to manufacturing is the next frontier of time-to-market gains. Their focus is no longer just faster PCB design, which emphasizes and prioritizes the design phase of new product development. Instead the trend is towards PCB design and manufacturing, and giving equal weight to design and manufacturing. The question, then, is why is this happening, and why now?

Looking back from today’s vantage point, it is an obvious and necessary direction. Electronics manufacturers always list time to market, cost and quality as top priorities in new product introduction. Be the first to market, produce it at the lowest cost, and provide the highest quality. To be successful, the manufacturing process and its many issues, requirements and challenges must be minimized before production begins.

The demands from this new focus on the transition of design to manufacturing are to support a new downstream-focused engineering process, develop or enhance our tools to analyze designs for “manufacturability” issues, and support industry standard, intelligent design exchange file formats that drive the entire manufacturing process for new products.

Sunstone’s Matt Stevenson Shares Insights From New PCB Design Book

10/27/2022 | Nolan Johnson, I-Connect007
There’s designing the “perfect” circuit board and then there’s designing a board that is “perfect for manufacturing.” While seasoned designers and design engineers understand many of the nuances, PCB fabricator Sunstone Circuits has just published a new book specifically for new designers who have the knowledge of design but are still learning what it means to get the board manufactured. Sunstone’s Matt Stevenson takes the reader through a series of situations that should help clarify what’s happening in the fabrication process and how to adjust a board design to be better suited for manufacturing.

What Happens When You Assume?

07/05/2022 | I-Connect007 Editorial Team
What is design with manufacturing and what does true DWM look like in operation? In this interview, I-Connect007 columnist Dana Korf explains what it will take to achieve total communication among all the stakeholders in the PCB development cycle. He also stresses the need for everyone involved in PCB design and manufacturing to stop making assumptions, even at the risk of being labeled as “that guy” who asks too many questions.

Master the Art of Communication With Manufacturers

06/30/2022 | Kyle Burk, KBJ Engineering
As mentioned in the May issue of Design007 Magazine, design is performed, at times, in a vacuum. But it doesn’t have to be that way. Whenever circumstances allow, design should be performed by communicating with all stakeholders throughout the design process, hence the emphasis on the word with in DWM. Communication can occur through personal correspondence such as email and voice conversations or through more formal design meetings—in person or through videoconferencing. No matter which means of communication you prefer, it’s important to communicate early and often with stakeholders involved in the downstream processes as you bring your project to realization.
