Insulectro Works to Bridge the Fabricator/Designer Gap

Reading time ( words)

Barry Matties sat down with Insulectro’s Megan Teta and Mike Creeden to discuss trends they see in the materials market and how they’re working to bridge the gap between fabrication and design, including helping designers understand what they can do to make a board more manufacturable.

Barry Matties: First, give us a brief snippet of Insulectro and what you do.

Mega Teta: Insulectro sells all Isola and DuPont laminates in the industry. We’re aligned with some of the best-in-class suppliers. We also sell materials that go into almost every process inside of a PCB fabrication shop.

Matties: Mike, you recently joined Insulectro in a design engineering capacity. Talk a little bit about your new role.

Mike Creeden: I joined Insulectro this year in May as a technical director for design education. Our goal is that we can enable and empower our customers, the fabricators, and support the OEM market. Our goal is to help the OEMs make intelligent material decisions early.

Matties: One of the things that I hear in most of the presentations at AltiumLive Frankfurt is that materials matter very early on from the design point of view. Why is that so important?

Creeden: Megan and I were discussing that earlier. It’s part of the message we are attempting to bring to this week’s event. Materials matter now for three major reasons.

First, when a designer attempts to solve the layout, it’s often a very dense, complex physical layout puzzle. Materials are an integral part of the design because as circuitry becomes smaller, the pitch of the device is reduced, and you need to utilize reduced material sizes.

Second, as boards become smaller, their ability to be manufactured is more challenging.

And the third reason is circuit performance is getting higher. A higher-performance board has more criteria placed on the layout, and the material affects that because when most people connect to a board, they see a wire connecting two parts. They think that the voltage and current establish the transmission line, but that’s only partially true; they’re factors, but the energy exists within the dielectric material, which is the space between any signal or power plane and its return path. The materials matter because they are factors in the equation for signal/voltage performance.

Matties: And from your point of view, what trends are you seeing in materials right now?

Teta: We’re all about trying to maintain lower Dk and driving that loss down while still making the materials manufacturable. From the Isola side, all of our materials are glass-reinforced because it’s one of the easiest materials to drill, laminate, and maintain your registration and scalability, etc. We’re trying to use things like lower-Dk glasses and take copper foils that are thinner and thinner to drive all that loss down.

Matties: The last time I did an interview with Isola CEO Travis Kelly, we talked about the new factory being built. What’s the progress on that?

Teta: The presses are coming. In the U.S. market, prototyping is a big deal, so trying to get material as quickly as possible is critical. Also, with the high-speed digital market, there are a lot of different core offerings, so trying to keep all of that in stock is a little bit trickier. The new facility is aimed at making those laminates as quick as possible.

Matties: It seems like the strategy there were smaller lot sizes and more flexibility.

Teta: Exactly. There are going to be three brand new presses that will outperform old presses from the facility in Chandler, Arizona. These are going to be aimed at doing lower quantity with a higher mix.

Matties: One of the things that we hear a lot about is that the designers need to talk to the fabricators sooner than later. Part of the core strategy of Insulectro is bridging that gap, correct?

Creeden: Yes. If you complete your layout and then approach the fabricator, you may find out any one of your decisions along the line for solving the layout and feature size or satisfying electrical performance are unbuildable. If you’re finding that out at the end of the design phase, you may have to go back and start somewhere much earlier in the process, if not all the way at the beginning. Most companies’ design schedules cannot support that. Oftentimes, they will compromise, thus lowering the reliability, performance, or anything that might be unacceptable to their end customer.

Matties: Are you focusing on reaching OEMs and connecting them with fabricators with the designer in that mix? What’s your model?

Creeden: For the most part, OEMs already are connected to the fabricators, and Insulectro currently is working with most all fabricators. Our goal is to accomplish change together. Therefore, we call it our ACT (Accomplishing Change Together) Program, whereby we work with the fabricators, helping them support their customers. For example, we don’t want to suggest a new material at the last minute. If it’s a new material, we want the OEM to be in contact with their fabricator alerting them early. We’re eager to make sure that the fabricators are prepared to best serve the end goals. Timely material choices help to ensure adequate delivery, stocking, and that process issues are met. Megan can speak to delivery and stocking issues. We value being able to deliver all these materials very quickly.

Teta: Insulectro is a stocking distributor, and we also have some manufacturing, cutting down materials, drilling holes, etc. Our goal is to get the material as fast as possible. We’re also working on our customer portal and making sure the fabricators can see in real-time what’s in our inventory and where it is. For example, a fabricator might San Jose sometimes will call and go to pick up the material the same day; we’re able to do that because they can see what we have in stock.

With material availability, we also understand that we need to maintain certain standard materials that are always going to be in stock. And that’s what’s important about talking to the designers and ensuring that when they build their stack-ups, they use the materials that we have. Isola does a great job of having a lot of different things available, but you don’t want to have something that is going to be used by two different customers.

Matties: Back to my point about connecting the OEM with the fabricator, I understand that connection, but I was talking more about you going to the OEM and being the connector between the OEM and fabricators in many ways.

Teta: Our goal is to work with the fabricator and have them bring us into their customers, so we go on sales calls with the OEMs all the time.

Matties: It’s kind of the reverse. You’re becoming an extension of the fabrication marketing department with brilliant expertise.

Material Conservation: The PCB Designer's Role

09/01/2022 | I-Connect007 Editorial Team
During these times of supply chain uncertainty, many product developers are considering new ways to conserve materials—from laminates to components, layer reduction, and everything in between. Barry Matties and Happy Holden recently spoke with Alun Morgan, president of EIPC and technology ambassador for Ventec, about material conservation strategies for today’s PCB designers and design engineers. Alun explained why this may be the perfect time to educate PCB designers about conserving materials: When a model is broken, the people involved are much more open to new ideas.

Designing for Material Conservation Means Changing Attitudes

08/29/2022 | I-Connect007 Editorial Team
It makes a lot of sense: During times when the supply chain is stretched to the breaking point—and the last few years certainly qualify—what if PCB designers created boards that used fewer components and less laminate? Do PCBs still have to be 0.062" thick? Why not reduce layer count while they’re at it? Andy Shaughnessy and Nolan Johnson spoke with I-Connect007 columnist Dana Korf about the idea of designing a PCB with material conservation in mind. Is it a great new idea, or are we opening a whole new can of worms and a separate group of problems?

Design Tips for Lowering Costs of Fab and Assembly

08/25/2022 | Cherie Litson, CID+, Litson1 Consulting
This is the million-dollar question of every project: How can I cut the cost of the PCB? There are about a thousand answers to this question. There are a few simple guidelines that everyone can follow to reduce costs. I talk about them in my IPC CID and CID+ courses. Designers, fabricators, and assemblers talk about them in a variety of articles. Some professionals who have published some great articles on cost-saving strategies include Tara Dunn, Happy Holden, Chris Church, Kella Knack, Judy Warner, Julie Ellis, Lars Wallin, and many, many others.
