A Conversation with Industry Icon Harvey Miller

Harvey Miller has been in the PCB industry for more than 40 years, and while I’ll let him disclose his exact age, I think it’s safe to say he’s probably seen it all. I recently sat down with Harvey at a local wine bar in Palo Alto, CA to learn more about his history in the industry and where he sees it going forward from his truly unique perspective. I must admit I was a bit inspired when Harvey arrived to our meeting wearing jogging shorts and running shoes. No surprise after what his doctor recently shared with him.

Barry Matties: Harvey, thanks for joining us today. You have been in the industry for many years. What year did you get started?

Miller: In the Middle Ages.  

Matties: There is a lot of speculation as to your exact age. Can you clarify for our readers?

Miller: You know, I have no problem disclosing that. I turned 93 on November 23, actually. A year ago, a cardiologist at Stanford told me that I have the heart of a 40-year-old, so I guess it’s 41 now. According to the actuarial tables, I am right around 79 or something like that.

Matties: So you are here for another 30 years.

Miller: Or I have been dead for about 14 years. [laughs]

Matties: It was a different world when you were born.

Miller: Yeah, it was 1922. The big growth industry was the automotive industry.

Matties: It’s the growth industry today too, isn't it?

Miller: Some things never change, right? It’s a different kind of automobile now—not the Model T. Of course, that is when forced obsolescence was born. William Durant of GM came up with the yearly models and that has been the model ever since. Now they do it by Moore's Law. I don't know what’s going to happen when Moore Law's runs out, because that has been the mechanism for obsolescence. Of course it won’t run out; there will be other things that will take its place.

Matties: What sort of education did you have?

Miller: I studied economics at the University of Michigan.

Matties: Were you born here in the San Francisco Bay Area?

Miller: No, I was born in Baltimore, Maryland but I grew up in Northern Ohio and then went to the University of Michigan. My father was a salesman, actually. He sold furniture. In the 1920s, Middletown, Ohio, was at the center of the automobile industries. Middletown as well as Akron were tributaries to Detroit. Akron backed them with tires, of course. Canton had tin can roller bearings and Diebold made safes and other things, and now they make ATMs.

When I was in the Army they sent me to study electrical engineering for 18 months, but that petered out because the war was over. They had a special program, and I got lucky because I was always good in those intelligence tests, and that is how I spent the war years. I later went back to the University of Michigan.

Matties: So not only were you trained in electrical engineering, you finished up in economics. It sounds like you were very well-suited for analysis in our business. Has your entire career been in circuits?

Miller: I went to work for a consulting company as a precursor. It wasn't as a participant. I never had my hands in the chemistry, but just as an analyst.

Matties: What year did you start?  

Miller: I worked for a bunch of OEMs and back then whenever an OEM got to around $100 million they built a board shop. They all had board shops. I guess when I got interested in boards and printed circuit technology it was probably the early ‘70s, maybe 1973 or so.

In those days, probably more than half of the shops were captive shops, and certainly then for the next decade and through the 1980s. It wasn't until Moore's Law forced density and the fabrication got a little too sophisticated that OEMs like IBM, etc., decided that it wasn't their business. That’s when all the big independents started to blossom and bloom, like Hadco and Zycon, etc., in response to the captives getting out of the business.

Matties: In all the years that you have been involved in this industry, what is the most surprising thing that comes to mind?

Miller: I guess the most surprising thing is the growth of the Chinese industry, because nobody would have anticipated that.

Matties: What do we have left in the U.S.? Something like 280 shops?

Miller: Around 300, but it’s the dollars that matter. It’s been totaled around $3 billion, which represents 5% worldwide. That is another surprising thing. The North American share went from 90% to 5% between the years of 1975 and 2015.

Matties: But most of it left around 2001; it was like somebody turned off a light switch. It was just gone. That was surprising, but there was a big race to low-cost labor.

Miller: And that is part of a pattern. It wasn't just the board industry, obviously. People talk about reshoring, but they don't realize it is going to take one of those paradigm shifts. So we are going to do an end run around those guys over there. That is what we should be looking at, not reconstituting the old technology and beating them with that, because we can't.

Matties: It has to be something new, like the Occam process.

Miller: I think embedded is the more general term, and Occam includes that. What Occam and Joe Fjelstad did was add another feature to embedding—which has not made an appearance yet, in general—that separates the two platforms. I’m paraphrasing Joe's work on Occam, but he had one platform for the components and another platform for the interconnect. Except most of the interconnects are relegated to the third dimension. That does a lot of really wonderful things, because it relieves the substrate of the constraints for doing both. They’re two separate functions: holding the components and interconnecting them. They should not be on the same substrate, because one of the drawbacks is you have conductive anodic filaments (CAF). They grew up with the glass cloth idea. They needed a really rigid substrate and glass cloth with epoxy cure made a great substrate.

And that is the backbone of the conventional board industry. But it has the drawback that as the dimensions get smaller, filaments in the glass are conductive, and it shorts. If you separate the two functions of holding components and interconnecting them, then you are free to go to all kinds of other substrates that don't have that drawback, besides the cost savings, etc. So embedding is the general word and I think Occam is a little twist that adds a lot to that, which people haven't seen yet.

Matties: How long do you think it will be before we really embrace embedded technology, because solder joints are the big cause of failure, right?

Chemical Legislation and Restrictions on Solder Masks

04/27/2023 | Chris Wall, technical director, Electra Polymers
Ever since liquid photoimageable solder masks (LPISMs) were introduced, their UV exposure speed has been a key factor in their performance. The LPISM is coated onto the PCB, dried, and then selectively exposed with UV light via a phototool, or more recently, via direct imaging using LED or lasers. The exposed areas polymerise and become insoluble in the developing solution. The polymerisation is initiated by one or more chemicals called photoinitiators, which are components of the LPISM.

ICT Seminar 2023 Review: Energy, Thermals, and Assistive Technology

Widely believed to be the traditional Centre of England, Meriden was a popular venue for a gathering of the UK printed circuit community this month. They braved the forecast of heavy snow for the Institute of Circuit Technology’s annual general meeting to learn about current developments and challenges in a thought-provoking technical seminar and to network with industry peers and contemporaries. Thankfully, the forecasted heavy snowfall did not reach Meriden until after the event; we only had a few flurries, although the weather caused considerable disruption elsewhere in the country.
