AltiumLive Frankfurt 2019: Carl Schattke Keynote

“How many here can remember manually taped artworks?” No more than three hands were raised in an audience of over 230 at the AltiumLive 2019 European PCB Design Summit in Frankfurt, Germany, as IPC Advanced Certified Interconnect Designer Carl Schattke introduced his keynote, entitled “Making and Breaking the Rules.” Schattke had learned PCB layout as his father’s apprentice, hand-taping several hundred PCB designs in the 1970s.

They also discuss Atotech’s portfolio of various chemistries. Johan came to Atotech in August 2019 through the acquisition of J-KEM where he held the position of CEO. Johan stated, “We are pleased J-KEM has joined the Atotech family, as it makes sense for both sides.”

Calumet Electronics and Averatek Team Up on A-SAP

Nolan Johnson talks with Brian Hess of Calumet Electronics and Mike Vinson of Averatek about the new, insertable additive processes that the companies are working on together to help factories running primarily subtractive processes to quickly convert to very high-density interconnect (HDI) features, including trace and space from 2.5-mil line and space to 1-mil line and space and below.

InduBond: Magnetic Induction Lamination

In this video interview, part of the productronica 2019 coverage, we spoke with Víctor Lázaro, R&D manager and technical director at Indubond. Víctor describes Indubond’s innovative methods for heating the boards to effect lamination through magnetic induction. Victor discusses the energy and operational efficiency that an induction method brings to the equipment: thermal profiles.

Future Trends in Flying Probe Testing

Peter Brandt, director of sales for Europe and Japan at atg, sits down with Pete Starkey and Barry Matties, gives his views on market requirements and testing technologies, and explains how flying probe testing is becoming the industry standard at all levels of production—and in many cases, the only practicable solution.

Market Drivers and ESI’s Ongoing Developments

During productronica 2019, the I-Connect007 Editorial Team met with some of the industry's top executives, managers, and engineers.

Words of Advice: What are Your Biggest Design Challenges?

In a recent survey, we asked the following question: What are your biggest design challenges? Here are just a few of the answers, edited slightly for clarity.

AltiumLive Frankfurt 2019: Jeremy Blum Keynote

Blum was a great advocate of considering the PCB in its holistic context and designing beyond it. Understanding the software needs ought to be of prime importance for the designer, and he believed that writing even the most basic firmware would help to ensure that the resulting electronics would be debuggable and equipped to handle the needs of the software development team.

EIPC Winter Conference—Speakers and Papers

I recently spoke with Kirsten Smit-Westenberg, executive director of EIPC, who is planning the EIPC winter conference set for February 2020 in Rotterdam, Netherlands. Kirsten discusses the conference topics, which are based around the needs of the next-generation electronic devices, and changes in fabrication solutions for PCBs, PCBAs, materials, and technologies.

Sunstone Circuits on Staffing Trends in the Digital Age

Sheri Kuretich, human resources manager, and Nancy Viter, VP of operations, of Sunstone Circuits speak with Nolan Johnson about what they see from the perspective of a prototyping shop, the current state of the hiring market, and how they have used ISO 9000 as an information repository to pass technical knowledge from experienced employees to newer ones.

Decreasing Bend Radius and Improving Reliability- Part II

Many of the issues that arise when using a flex circuit come from a lack of knowledge about how to properly design one, especially when the circuit is required to bend. Many novices will design a circuit that calls for bending the flex in too tight of a bend radius, which can cause damage to the circuit and lower the reliability of the end product. This series of articles will focus on the seven key aspects to consider when designing for maximum durability and maximum “flexibility.”

Industry Wind Vane: Future Development Through the 2019 HKPCA Show

The annual HKPCA Show, which has been renamed the 2019 International Electronics Circuit Exhibition (Shenzhen), will be held from December 4–6 at the Shenzhen Convention and Exhibition Center. This year’s exhibition will be jointly organized by the Hong Kong Printed Circuit Association (HKPCA) and the China Printed Circuit Association (CPCA) and will provide a more efficient business platform for all visitors. The PCB007 China Team interviewed a representative from the HKPCA about the exhibition, the industry’s current situation, and future developments.

5G is Coming With Quantum-Level Advances and Features

I am sure that, by now, all of you have heard about 5G (the fifth-generation of mobile phone and data communication standards). I am also relatively sure that many of you think that this means neat, new cellphone features, and perhaps more texting and selfie abilities. While that may be true, getting a new cellphone for those reasons would be like getting a new car because you want a different color.

Book Review: The Printed Circuit Designer’s Guide to…Executing Complex PCBs

If you are serious about designing complex PCBs (most designs today are far from elementary) and even more serious about doing it right the first time, then this is the book for you. Loaded with guidelines for designing cutting-edge PCBs, this book is filled with real-world examples and tips, tricks, and techniques by some of Freedom CAD’s most experienced designers.

Vertical Conductive Structures, Part 4: Tuning Your Signal Performance

The objective of this article is to demonstrate the possibility of using a stitching element as an alternative to the point-to-point connections that are used with traditional via technology. Point-to-point connections have the best performance in terms of signal integrity (one via less in the connection that distorts the signal). A via is mainly a capacitive element that causes signal loss/ dispersion.

Words of Advice: 5G Reliability

In a recent survey, we asked the following question: Do you think 5G will improve the reliability of communication? Here are a few of the answers, edited slightly for clarity.

Flex Standards Update With Nick Koop

This month, I interviewed Nick Koop—director of flex technology at TTM Technologies, a veteran “flex guy” and instructor, and a leader of several IPC flex standards committees. Nick provides an update for the committees he’s involved with and discusses some of the challenges that he sees as more designers enter the world of flex.

Multilayer Press Technology Using Magnetism to Produce Lamination Heat

A revolutionary concept in multilayer press technology has been developed that uses electromagnetic energy to heat the existing stainless-steel separator plates with a never-before dreamed-of accuracy and precision. The heating and cooling systems—embedded within a robust hydraulic press inside a vacuum chamber design—are controlled using a temperature feedback loop that guarantees perfect fidelity between the press recipe and the press result.

Communication, Part 6: The Importance of Technology Fit

In the final installment of this series on how PCB fabricators and designers can better communicate, Bob Chandler from CA Design and Mark Thompson from Prototron Circuits discuss the importance of “technology fit” and how this concept impacts the synergy of the two parties involved.

Solder Mask Tack Dry

As a general rule, the tack-dry temperature should be as low as possible; in other words, it should only be as high as necessary. If the temperature is too low, the evaporation rate for the solvent will be to slow, and the solder mask will not dry in a reasonable amount of time. If the temperature is too high, however, the dry time certainly will be excellent, but it could create a solder mask lock-in with repercussions by the developing time.

Words of Advice: The OEM Systems Designer

In a recent survey, we asked the following question: What advice would you give an OEM systems designer? Here are a few of the answers, edited slightly for clarity.
