We also have an excerpt from a previous interview with Happy Holden, in which he details the history of DFM strategies from the earliest days of PCBs. Next, Siemens' Patrick McGoff takes a coun- terpoint position. As he points out, today's EDA tools and design techniques already enable complete transparency between design- ers and manufacturers under the umbrella of DFM. Is DWM just another solution looking for a problem? Then, Altium's Ted Pawela and MacroFab's Misha G o v s h t e y n d i s c u s s their recent Altimade partnership, which has created a transparent DW M e nv i r o n m e n t for designers, fabrica- tors, distributors, and EMS supplier s. Kyle Burk of KBJ Engineer- ing explains that there are times to use a total DWM process, but every design is not going to need that sort of focus from your partners. And Scott Miller of Freedom CAD Services discusses their DWM process from a design bureau's point of view, and how to implement such a process at your own com- pany. We also have stellar columns from our regu- lar contributors: Barry Olney, Matt Stevenson, Steph Chavez, John Coonrod, Jade Bridges, and Joe Fjelstad. Summer is here, and the design community is heating up too. See you next month. DESIGN007 Andy Shaughnessy is managing editor of Design007 Magazine. He has been covering PCB design for 20 years.

But the DFM pro- cess itself is clearly not as effective as it could be. e average PCB design undergoes an average of 2.9 respins, according to a recent Lifecycle Insights study—stark evidence that DFM is not being embraced by all stake- holders. Designers and manufacturers oen don't begin communicating until many of the most critical, expensive layout decisions have already been made. But it doesn't have to be this way. Now, DWM promises to get every stakeholder on the same sheet of music, from the begin- n i ng o f t h e d e s i g n process through box- b u i l d . Yo u w o u l d k now your fabr ica- tor's sweet spot and preferred format for data package handoff. He would know your design intent from the word "go," help you cra the perfect layer stackup, and be aware of your impedance needs before the 11th hour. And your EMS provider would know about any tough-to-find compo- nents far before your bare board arrived. So, this month, we asked our contributors to shine a spotlight on DWM: How do we initi- ate it, and what does DWM look like in action? Why should you embrace DWM? How can DWM succeed where DFM fell short, despite the industry's best-laid plans? And when is DWM not necessary and just a waste of your fabricator's time? We started by interviewing Dana Korf, who explains the need to take the guesswork out of the designer-fabricator relationship, and how to stop making—and accepting—assumptions in the design cycle. Columnist Kelly Dack dis- cusses the benefits of DWM's total transpar- ency among all stakeholders in the product
