IPC-2581 Update

It’s been a while since I updated readers on the IPC-2581 Consortium. Here’s a few tidbits:

  • The group of supporters continues to grow, and a couple large IT and test equipment OEMs are now considering joining. At least one announcement could be coming shortly.
  • The verification team, led by Ed Acheson at Cadence, is making progress. They are looking at some designs to use for test runs. At least 10 designs are expected to be validated using the members’ CAD and CAM tools.
  • Wise Solutions expects to have an IPC-2581 viewer by January. It will likely be made available through multiple websites.
  • The Consortium will have a booth at the IPC Apex show in late February and PCB West in September. Members will also have a poster at Apex and will make a presentation at PCB West.

Here’s a question: Should Mentor or Frontline (which Mentor owns a 50% stake in) join the IPC-2581 Consortium? Feel free to reply here or directly to me if you wish.

PCB West Recap: Still Great After 20 Years

I’m thrilled to be reporting on PCB West 2011 because for the past few years I haven’t been able to attend. I had almost forgotten what it was like to be among that rare breed of “off-grid” individualism, the Circuit Board Designer.Lately I’ve become more involved in IPC standards development committees and therefore feel obligated to attend those conferences, but since few designers participate in IPC activities, PCB West felt like coming home again. If you are one of the designers working alone out there for your company, or are a lone designer supporting multiple companies, this conference is a great opportunity to meet your peers, get away from the daily grind for a few days and see what the rest of the world is doing …  

20 and counting? This was the 20th anniversery of PCB West? Seriously? How could we have gotten so old already? Now I’m feeling nostalgic … UP Media gave out “20 Years and Still Off-Grid” t-shirts to literally everyone that registered. I thought that was a really nice thing to do. Thanks, Uncle Pete! (and while I’m thinking about it, thanks to K&F for supplying free Starbucks coffee for everyone!)

Continuing education. The conference started off with a bang as I attended a presentation by Kevin Coates where he introduced a new series of devices by Texas Instruments (well, new to me anyway) where fine pitch BGAs are being developed using a pin-out method that leaves room for fan-out vias and decoupling devices. Using these “via channel” devices may enable designers to use conventional board fabrication technology, where an HDI solution was required before. It was nice to hear additional comments by Wayne Pulliam, who works on similar efforts for AMD.

Darren Hitchcock’s “Design for Manufacturing” presentation was very informative, mostly focusing on various board materials and their characteristics.
Gary Ferrari gave a great introduction to HDI technology, the various types of HDI constructions (and the materials required for them) and the use of microvias. He gave some good real-world advice and warned about some common pitfalls, and if you are moving in the direction of HDI I would strongly recommend this course. Gary has done so much work with this type of fabrication at his company (FTG), and with so much related experience in his involvement with IPC, you can pretty much take whatever he says to the bank.
Susy Webb seems like the hardest working gal in the game, and has nearly accomplished a complete curriculum for new board designers.
Starting with the basics in her introductory “Symbols and Schematics” class, and moving from “Parts and Placement” through “Routing and Finishing” and even “PCB Layer Stackups,” finishing with “EMI” and “Signal Integrity” presentations. She is getting close to offering the new designer a start-to-finish introduction to the whole electronics development process.
And the good news? All of her presentations are available on the Proceedings CD.
Finally, many of you may wonder what exactly happens to your Gerber data once it leaves your CAD system, and whether that ubiquitous fabrication note “Data May Not Be Modified” really means anything at all. Well, Mike Tucker’s presentation about CAM departments is a welcome addition to any PCB design program, and thanks go to Colonial Circuits (his new employer) for letting him continue to present it.
This is definitely something any board designer worth his salt should know about.
Feeling left out? I apologize to all of the presenters that I wasn’t able to mention in this review. With multiple events happening in every time slot, I simply wasn’t able to make it to everything this year. Fortunately, the proceedings disk contains most of the information from the conference and is available from UP Media at http://pcbwest.com/2011/proceedings/.
Exhibitionism. Although the exhibit spaces have seemed to be shrinking in size over the last decade or so, UP Media does a great job of bringing folks onto the floor. The time frame was shorter, and I suspect the exhibitors are happy enough with not having the show drag on and on for days, so that now the entire event happens in a single session! I love it.
Everyone is there for one entire day and it seemed downright festive.
The event included free lunch for everyone, bringing a lot of traffic into the space virtually the moment it opened, and ended in the evening with open bar for everyone, so even those who need a little of that old-fashioned “social lubricant” could get into the scene. The vendors I talked to seemed to be getting a lot of worthwhile leads this year, and I sensed a real note of optimism that I haven’t felt lately. Hope it was a worthwhile experience for everyone who participated.
Gossip column: Happy for Happy. Many of you know Happy Holden from his long career at Hewlett Packard, many of you know him from his educational conference presentations while working with NanYa, many of you know him for his most excellent introduction to HDI, The HDI Handbook, many of you know him for his work divining the future for Mentor Graphics, and many of you know him for his “retirement” to become the CTO of Foxconn’s Advanced Technology Division in Taiwan. I might have predicted that we had seen the last of Happy; that he had moved so high up the ivory tower that we would never hear from him again. Not so! Happy is moving back to the states! (hope he doesn’t resent me for this announcement). Maybe we will all benefit from his presence again.
Stay tuned … (Michigan?)

Howdy PODners! OK, how many years ago did we start talking about a Universal Library? How long ago was it that Tom Hausherr started collecting PADS library components, analyzing them, collating them, creating a consensus that eventually turned into the PCBLibrary Viewer and Calculator and Wizard?

And when these tools got linked together with the IPC-7351 Land Pattern Standard, it seemed like we were close to crossing the goal line, from then on into the future the world could have a consistent approach to creating reliable footprints for every major CAD system. So, what happened? Well, the short story is that Valor bought PCBLibraries, which seemed like a good idea since Valor was already supporting every major CAD system, but then Mentor Graphics bought Valor. Uh Oh! would Mentor support the dream? Not exactly … they soon started stripping off the interfaces to the competitor’s products, and the most recent news that is that in July they kicked Tom and his team to the curb. sad, Sad, SAD. But, looking at it another way, it could be the best thing that ever happened to propel us toward the dream of a Universal Library, because Tom and his Partners are back together and working on a monster plan for a new web-based library (which will eventually be at http://PCBpod.com). Right now they are putting together the parameters for a set of new and improved land pattern conventions that address many of the common issues. For example, why should we be screening so much silkscreen underneath components for high-volume products that can’t even be seen after assembly? We are wasting a lot of ink for no reason, folks.
Anyway, that might be a minor issue for many of you and it is just an example, but the good news is that these issues are actively being discussed, hopefully to be resolved with the IPC during some meetings in October, and then these parameters will be public-domain for all to use.
And what will happen to Mentor’s calculator? Who cares…!

PCU for me and you. Also, you’ve probably already heard, but UPMedia is putting together various educational materials which will hopefully evolve into a full curriculum under the banner “Printed Circuit University.

Registration is free, and once your account is set up you will have access to many free resources, and for a fee you can access the in-depth tutorials such as Eric Bogatin’s Signal Integrity series. Check it out! You might even find some videos there from this year’s conference by Kelly Dack.

The missing piece. Finally, the conference just wasn’t the same without Rick Hartley, one of the educational icons of our industry. Hope you’re feeling better, Rick!

Surfin’ the learnin’ curve,

We have posted the full announcements on PCD&F’s site. Thanks to all who attended!

Talk Isn’t Cheap

Communicating is hard. It took thousands of years just for man to develop a common language. I don’t suppose, then, even in our “enlightened” state, we should expect it to be easy to develop a common, complete method for describing all the myriad features of a printed circuit board.
This week at PCB West, the Silicon Valley annual trade show, a special panel will convene to address just that decades-old issue. (Disclosure: I’m the moderator.) I don’t expect the group to solve all the industry’s data problems in just 90 minutes, but I do think a few key aspects will be noted.

Here’s a question I plan to raise: Would the problem of unintelligent data files be essentially resolved if the initial cost to upgrade were lower?

Upstream, Intel, for example, sends an army of engineers to its suppliers to help them implement new processes. Few companies have the resources of Intel, of course. No fabricator does. And this leaves the fabs in a bind: They know that Gerber is insufficient, and spend countless hours massaging (often without their customer’s knowledge) the bad or incomplete data received from design. But with tooling jobs stacking up on their desks, and margins cut to the bone, they claim no resources to spend on implementing one of the richer data transfer formats like ODB++ or IPC-2581.

So who pays?

Neither IPC nor Valor make any money directly from their respective data transfer formats, so it’s unlikely either would see the value in extending themselves further by underwriting the onsite development and implementation work. (Whether they should anyway is a column for another day.) Designers tend to be risk-averse: They are unlikely to risk their jobs on something upper management is not mandating. Thus, it may be that the fabricators need to start assigning a CAM engineer to its key customers — perhaps one at a time, to keep costs down — to help them get up and running — no matter which rich format they choose.

The argument for switching to a superior format(s) is that manufacturers will save money down the road. I understand, however, that quantifying the cost savings is exceedingly difficult. Moreover, as one CAD developer told me, there’s an unwritten incentive for the status quo (read: Gerber) because manufacturers don’t want to appear inflexible.

I would argue that the industry’s margins can’t afford to keep sending bad data downstream and hoping for a miracle in return. Fabricators over the past decade have lost most of their influence over the printed circuit board development. This is an area where they can truly coach their customers — and add value in the process. They should grab it.

Time Keeps on Ticking, Ticking …

Twenty years? PCB West is 20 years old? I feel like Rip Van Winkle all of a sudden. I close my eyes, take a walk around the block and poof, those years have flown by. And at the risk of dating myself, I was barely in my forties when we started PCB West. (You do the math.)

It only seems like a long time when I think about some of the shows and things that happened back in the heady days of the 1990s. Then there are some photos floating around of those early PCB West shows. Looking at those pics, I can see I’m not the only one who has aged a bit. And speaking of age, in some ways the PCB design world has also aged. I’m sure some of you remember the PCB Benchmark that we used to do at PCB West. Back in those days, it was not unusual to have more than a dozen different EDA vendors participating in the benchmark. Today most of those companies have been gobbled up by three or four companies. During the days of the first PCB Design Conferences, personal computers were just coming into wide use. The DOS OS was still limited by hardware and software, and most design systems were still operating on UNIX-based machines from Sun or HP. By comparison, I expect any day to hear of some EDA company releasing a product optimized for the iPAD.

In the early days as editor of Printed Circuit Design magazine, I used to talk about the Buck Rogers syndrome: When I was a kid, everyone expected us to be walking on Mars and riding around in flying cars by the year 2000. It’s what we saw on TV and what a country and society that knew few boundaries could imagine. While we may be a bit more realistic about expectations these days, the pace of change has accelerated. Think about this: When we started the PCB Design Conference, there were no cell phones or laptops (at least not for the masses), and we didn’t even imagine email or the Internet.

The technology has changed over the years: finer features, many more pins on the components, and signal integrity issues are the norm. But, basically, it is the same process. In some ways PCB design has changed a lot in 20 years, but in some ways it is still the same. In my mind it’s a lot like the people involved. You’ve changed in some ways to keep up with the technology, but in the end, PCB designers are still the ones who turn that idea, that concept, into a tangible product. To me that means you are still the indispensable link in the chain.

Thanks for all you do, and thanks for the first 20 fantastic years of PCB Design Conference. We couldn’t have done it without you.

A New Trend in Assembly Shows?

Years ago, three major events dotted the US electronics assembly trade show landscape. They included Nepcon East, Surface Mount International, and the mother of them all, Nepcon West.

While Nepcon West was the undisputed champ, all three shows were worth attending, and exhibitors often made new product announcements at each one.

Interestingly, and for reasons too detailed to get into here, none of those shows exist today. And for much of the 2000s, the place to roll out new products became IPC’s Apex. Other events were relegated to regional status, and traditionally were staffed as much by distributors as by OEMs.

There’s a few small signs that trend may be shifting again. While IPC Midwest, taking place this week in the Chicago suburbs remains a local show (and honestly, could they make seeing the exhibitor list any more user-unfriendly?), SMTAI is at long-last beginning to fill the niche for a seasonal alternative to Apex. To wit, we’ve received numerous press releases of late reporting new products to be introduced at SMTAI. That’s evidence suppliers see the venue as a viable place to make product launches.

Also at SMTAI, on Oct. 18, I am cochairing (with CIRCUITS ASSEMBLY columnist Sue Mucha) a panel titled “Global Strategies for Lowering EMS Costs” at SMTAI in Ft. Worth, TX. Topics include EMS in Eastern Europe; networking technical trends; improving quality, delivery and cost in high mix manufacturing; and vapor phase technology, and feature speakers from Kimball, Tailyn, Fabrinet and IBL Technologies. We conclude with a panel on building an EMS cost model.

I can’t mention these events without touting our own. Next week marks the 20th annual PCB West conference and exhibition at the Santa Clara (CA) Convention Center. Traditionally the industry’s leading conference for printed circuit board design and fabrication, we have beefed up the electronics assembly side (with a big assist from the Silicon Valley SMTA Chapter). Highlights include papers on low silver solder alloys, advanced packaging, new plasma-based PCB surface finishes, and lead-free electronics risk reduction, presented by such leading companies as Hewlett-Packard and Amkor. Check out the program at pcbwest.com.  We really hope to see you there.
