Current IssueShowing Some Constraint
A strong design constraint strategy carefully balances a wide range of electrical and manufacturing trade-offs. This month, we explore the key requirements, common challenges, and best practices behind building an effective constraint strategy.
All About That Route
Most designers favor manual routing, but today's interactive autorouters may be changing designers' minds by allowing users more direct control. In this issue, our expert contributors discuss a variety of manual and autorouting strategies.
Creating the Ideal Data Package
Why is it so difficult to create the ideal data package? Many of these simple errors can be alleviated by paying attention to detail—and knowing what issues to look out for. So, this month, our experts weigh in on the best practices for creating the ideal design data package for your design.

This Month in Design007 Magazine: Dear Designers—Please Include a Sanity Check
August 11, 2020 | I-Connect007 Editorial TeamEstimated reading time: 2 minutes

No discussion about fab notes and documentation would be complete without the insight from DownStream Technologies. DownStream has spent 18 years developing tools to help PCB designers provide more accurate, complete data packages to the fabricator. We recently asked Rick Almeida, DownStream co-founder, and Technical Sales Manager Ray Fugitt to discuss why so many fabricators are still receiving (and correcting) inaccurate and incomplete data from their customers. And if fabricators and designers are content with this current process, is it really a problem after all?
Andy Shaughnessy: It’s great to speak with you both, even by conference call. Can you tell us about some of the biggest problems that fabricators have to deal with, as far as data from their customers?
Rick Almeida: Ray’s experience is actually working for fabricators, so he’d have a pretty good technical knowledge of what some of the issues are. But from what we see as a company, dealing with this on a day-to-day basis, is that some of the problems are in a couple of different areas. One is there’s a myriad of data files that get handed off. The market, in general, is still Gerber-centric and not so much single manufacturing file-centric. Because of that, you have a lot of different data files and documentation to tell you how to use those data files, which creates issues. When you have so many different data files, you run into the issue of if all the data files are there and correct. Does the design itself line up with what the manufacturer is asking you to build? Those are the common things that we see people having problems with. Ray, do you want to add anything to that?
Ray Fugitt: One of the biggest ones we see, and especially since I’m in tech support now, is bad data out of the CAD systems. There is this thought throughout the industry that the CAD systems don’t put out bad data, but we see it every day.
Barry Matties: Why are they getting bad data out of the CAD system?
Fugitt: I have examples. Things like—I’ll throw the term out there, and you can put yourself to sleep Googling it—“self-intersecting polygons.”
Almeida: It’s just a conversion of the intelligent design into unintelligent Gerber files, and what that entails to drive a machine, as opposed to screen graphics.
Fugitt: We’re doing a translation, and just to carry that one just a little bit further is it’s illegal, per the Gerber spec, to get all the CAD system’s output and know how you can go any further with that.
Almeida: It always goes back to that common issue between design systems and manufacturing systems. This is at the end of the process, and it’s where the smallest amount of R&D is spent on the manufacturing side of the design tools. And that’s a large reason why people are still gravitating toward Gerber files, as opposed to an ODB++ or an IPC-2581 file; they just don’t have that experience.

Beyond Design: Refining Design Constraints
07/17/2025 | Barry Olney -- Column: Beyond DesignBefore starting any project, it is crucial to develop a thorough plan that encompasses all essential requirements. This ensures that the final product not only aligns with the design concept but is also manufacturable, reliable, and meets performance expectations. High-speed PCB design requires us to not only push technological boundaries but also consider various factors related to higher frequencies, faster transition times, and increased bandwidths during the design process.
