In Deep: The Art and Science of DFM with Gary Ferrari


Reading time ( words)

When the topic of DFM techniques came up, I knew I had to talk with Gary Ferrari of FTG Corp. Gary has been involved with designing and manufacturing PCBs for decades, and he’s the past co-founder and executive director of the IPC Designers Council. I caught up with Gary between Thanksgiving and Christmas, and we conducted the following interview.

 

Andy Shaughnessy: Give us a quick background on yourself and your role at FTG.

Gary Ferrari: I have been in this industry for more than 50 years. The major portion of this time has been spent in PCB design and manufacturing. I have spent some time in assembly, industrial robotics, and nuclear and fossil power plant controls systems design.

I serve as the Director – Technical Support for FTG Circuits. My main function has many facets. First is to work with our customer base during the design phase of their products. I help them design for manufacture, which includes fabrication, assembly, repair, reliability, and field service. This includes end-product performance, both electrically and mechanically. It sounds like a lot, and it is. To meet today’s advanced products within short design cycles, one must consider all these areas when selecting materials, components, etc.

Second is to represent them within the standards develop committees of IPC. Many current-day issues are discussed during the development meetings, which affect both our company and our industry. There are so many new, advanced technologies cropping up constantly. One must stay on top of them if one expects to survive in this industry.

I also provide IPC designer certification through EPTAC, an IPC licensed training center. These courses are quite extensive, exposing the attendees to many of the issues affecting successful designs.

Shaughnessy:  So, what can PCB designers do to make the fabrication process go smoother?

Ferrari: The most important item that a designer can do is to talk to their fabrication and assembly suppliers. Ask them about how your design practices are affecting their ability to manufacture with low yields and high reliability. Most important is to find out the areas that are the most troublesome. The designer has many ways to attack a given issue, and may be able to select a design solution that is easier to manufacture, resulting in higher reliability and lower cost. This is most important when doing a new design utilizing a technology that is new to the company. Most fabricators can draw from experiences gained through a wide variety of technologies they have worked with through a large customer base.

Julie Ellis: Communication and Fabrication Knowledge Critical for Designers

11/19/2018 | Andy Shaughnessy, Design007 Magazine
Field Application Engineer Julie Ellis of TTM sees it all: good designs, bad designs, and everything in between. Her classes on proper DFM techniques are always a big draw. She taught at the inaugural AltiumLive in 2017 and was back at this year’s event. I caught up with Julie and asked her to discuss some of the things she covered in class. As she points out, many issues could be eliminated if designers communicated with their fabricators and had a better understanding of how PCBs are manufactured.

Max Seeley’s PCB Design Career is No Fish Story

11/14/2018 | Andy Shaughnessy, Design007 Magazine
Max Seeley, senior electrical, PCB, and manufacturing engineer with 3M, was an instructor at the first AltiumLive event in 2017, and he made a return visit to this year’s event in San Diego. I asked Max why he decided to come back to AltiumLive this year and to share the story of his rather circuitous journey into PCB design, which included a turn as a custom aquarium builder. Everyone in PCB design has a different backstory.

Amway Sells Beauty Products—and Designs its Own PCBs

11/12/2018 | Andy Shaughnessy, Design007 Magazine
During AltiumLive in San Diego, I met Dugan M. Karnazes, an associate electrical engineer and PCB designer at Amway. The company is famous for selling nutritional supplements and soap, but apparently Amway has been busy diversifying over the years. I was interested in finding out more about Amway’s electronics development. Dugan sat down with me to discuss his role at Amway, and how this company grew into an $8 billion global giant.
