Weiner’s World—December 2017
Hold on to your seats! 2018 will be a year full of rapid changes, surprises, and growth. M&A activities will flourish. The supply chain will suffer shortages and changes as demand increases, copycats will rush to market, and new markets and potential suppliers will vanish before they are established.
The Impact of HDI on PCB Power Distribution
A key aspect of HDI technology is the use of microvias. For reference, the IPC HDI Design Committee has identified microvias as any hole equal to or less than 150 microns. Multiple types of HDI stack-ups associated with blind and buried microvias can be used to meet the density and cost requirements for today’s products. Design teams should develop stack-ups in conjunction with the fabricator to minimize cost and meet signal integrity requirements.

A Unique Norwegian Approach to Serving Customers
I met a lot of interesting people at productronica, with an assortment of different products on display. Such was my visit with Oyvind Tafjord, CEO of Visitech. His purpose at the show was to meet with his customers, so nothing unusual about that. But his customers also had booths (or stands, as they call them), which is an advantage for him, as he explains here.
AGFA: From Film to Inkjet Solder Mask
The productronica show was indeed filled with new technology, and it was great to meet with people and learn about it. This is precisely how I met AGFA’s Frank Louwet, who filled me in on the Dipamat inkjet solder mask they have been developing. It seemed an odd choice to go from film to solder mask, but as Frank explained, it makes perfect sense.
Ventec: Eye on the Future, with Automotive and Lighting Front and Center
Ventec’s Thomas Michels and Didier Mauve sat down with I-Connect007 Editors Patty Goldman and Pete Starkey and enjoyed an upbeat and enlightening conversation. Among the topics covered were the importance of working partnerships in maintaining supply chain continuity, market drivers for thermally conductive materials, and development of enabling technologies to support the automotive electronics revolution.

Full-Service Plating at Hofstetter
While strolling the aisles at productronica, I happened upon the booth of Hofstetter Plating. I was not familiar with this PCB company so I stopped to chat. It turns out they aren’t exactly a PCB fabricator, but provide a comprehensive plating service in Europe and occasionally beyond that, offering several exotic and unique plating processes.
Pluritec Wants to Remove Human Factor from Solder Mask
Solder mask remains a relatively hands-on task, which can result in human error. But equipment manufacturer Pluritec wants to change that. At PCB West, I spoke with Pluritec Vice President of Sales Lino Sousa about the company’s new spray technology that can turn solder mask application into what is essentially a push-button operation.

The PCB Norsemen: Industry 4.0, AI and CircuitData
As automation works its way onto the shop floors, it still struggles to replace humans in the supporting roles, such as designers, purchasers, brokers, and back-office staff. Where automation on the shop floor replaces humans in doing repetitive manual tasks, the supporting roles (at least some of them) require intelligence to understand and utilise information.
Groundbreaking Developments at liloTree
I was introduced to liloTree and Chief Scientist Kunal Shah by Joe Fjelstad. It seems this small company (with Intel as part of its pedigree) has developed a novel ENIG process that just may shake up the regular chemistry suppliers. This new process is described as cost-effective and ecofriendly while completely eliminating black pad and brittle solder joints.
AltiumLive Summit—Munich, Germany, Part 1
Altium held a very successful AltiumLive PCB Design Summit in San Diego, California at the beginning of October for the benefit of their North American design community, and followed it three weeks later with a counterpart European event in Munich.

Happy Holden, resident PCB expert, also joined the newbies on their field trip to ASC. In the following articles, Jonathan and Kiersten describe their experience touring ASC. Special thanks to Anaya for hosting the I-Connect007 team.
Planning a PCB: Signal Integrity and Controlled Impedance Considerations
Knowledge and experience are the two key elements when planning a PCB. Today’s PCB designers must have far more knowledge and understanding of the PCB production process than in the past. This is especially important when they plan and how they plan the stackup, via span, routing and power distribution.
Final Finishes: Taking Gold Thickness into Account
Martin Bunce was one of several people from MacDermid Enthone who presented at SMTA International this year. He sat down with me for a chat about his paper on final finishes, particularly with regard to controlling gold thickness.
HDI’s Beneficial Influence on High-Frequency Signal Integrity
The increasingly widespread use of finepitch ball-grid array (BGA), chip scale packaging (CSP), and other evolving technology form-factors means that new fabrication techniques must be used to create printed circuit boards (PCBs).
PCB Signal Integrity Optimization Using X-ray Metrology
It happens again. A new backbone router/switch build or a line card upgrade is approaching completion when something goes wrong. The system won’t operate at the targeted data rate. Deadlines are looming and the root cause of the problem is buried somewhere in a big rack of electronic components.
Strategies for Developing Copper Plating Systems
I-Connect007's Patty Goldman met with Dr. Albert Angstenberger, global technology manager for metallization with MacDermid Enthone Electronics Solutions, while at SMTA International. He presented a most interesting paper on copper pillar plating systems that we hope to publish in The PCB Magazine sometime in the future.
Experts Discussion: Signal Integrity and Impedance Control
When the content gathering for an issue on signal integrity and controlled impedance was officially underway, our I-Connect007 editorial team’s first stop was an “experts discussion” with industry experts: Mike Steinberger of SiSoft, Mark Thompson of Prototron Circuits, and Yogen and Sunny Patel of Candor Industries. This teleconference call was a whirlwind at times, but we captured valuable information that we have distilled here, for our readers.
Process Engineering & Defect Prevention
Defects may “manifest” or be detected in or after a specific operation within the printed circuit board manufacturing process, but the underlying root cause may have occurred earlier (perhaps much earlier) in the process.
3D Printed Electronics for Printed Circuit Structures
Printed electronics is a familiar term that is taking on more meaning as the technology matures. Flexible electronics is sometimes referred to as a subset of this and the printing approach is one of the enabling factors for roll-to-roll processes.

'Can Do' in CAM Outsourcing: CAM Engineering—Fast Turn-Around
Time-to-market has been the mantra for every successful technology company. The best among them have strong and integrated supply chains that march to the drum of the OEMs and EMS providers that bring that technology to market. A big part of that success, especially in North America and Europe, is the ability for PCB manufacturers to turn around complex PCBs very quickly. The hallmark of PCB production in these higher-tech, higher-cost regions is flexibility and responsiveness.

While in China recently, Barry Matties joined longtime I-Connect007 friend and contributor Hamed El-Abd of WKK to congratulate him on his upcoming retirement. They reflected on his time spent in the industry, specifically in China, how far it’s come, and where it might be headed next.
Laser Patterning & Metallization to Reduce Process Steps for PCB Manufacturing
This paper details a new methodology for the plating of conductive features onto glass dielectrics. A laser is used to ablate material from a glass substrate in the desired pattern, and copper is “seeded” into these features using laser-induced forward transfer of a copper foil.
Cycle Time Reduction Through W.O.R.C.
Lean, theory of constraints (ToC), quick response manufacturing (QRM), cross-training, and staticstical process control (SPC) are powerful, tried and true methodologies for process improvement. However, these tools are rooted in high-volume manufacturing environments and don’t always play nice in a high-mix, low volume (HMLV) operation. The new W.O.R.C. manufacturing strategy was specifically developed to overcome these shortcomings while capitalizing on their strengths.
Patty's Perspective: How do You Define Process Step Elimination and Automation?
This month, we can call our theme PSE&A—a fancy acronym for process step elimination and automation. Sounds straightforward, but what exactly do we mean by “process step elimination?” Does it refer to shortening the numerous steps involved in making a printed circuit board? There sure are a lot of them, but they all must be necessary—or why would we have them?
Victory Giant Technology: The Qualified Forerunner of PCB Smart Factories
The topic of the July issue of PCB007’s China Online Magazine is “Automatic PCB Factories,” focusing on the pressures of cost, delivery time and process, and the irreversible trend toward automated PCB factories.

Ltd., the first domestic PCB manufacturer who carries out large-scale implementation of intellectualization throughout the factory.
Mr. Laminate Tells All: PTFE is About to be Banned by IEC TC111
There, I said it. Technical Committee 111 of the International Electrotechnical Commission (IEC) is preparing to effectively ban PTFE (polytetrafluoroethylene) materials from electronics. As history goes, the electronics industry has focused on only two of the four halogens (bromine and chlorine) to be limited in order to be called “halogen-free” or more accurately “low-halogen.” But now, fluorine is being dragged down too, just because of its location in the periodic table.
I-Connect Survey on Process Step Elimination: What is More Important for Productivity?
Is utilizing the best technology out there the most important factor in improving productivity? Or is it automating certain, if not all, processes in your production? What about employee morale, what is its impact on the overall productivity of your line?

Megasonic Acoustic Surface Treatment Process for Enhanced Copper Electrodeposition in Via Interconnects
A printed circuit board is populated with a multitude of electro-mechanical components plus various active and passive devices such as transistors, capacitors, inductors and resistors, which enable the functionality and assembly of the PCB. Increasing the density of the components on the surface of a board enables greater functionality and use.
I-Connect Survey on Process Step Elimination: Cycle Time Spent on Final Inspection
In our recent survey on process step elimination for the upcoming issue of The PCB Magazine, one of the questions asked was the percentage of total cycle time spent on final inspection. Around half of the respondents answered they only spend generally between 1% and 5% of their total cycle time doing final inspection of their products.
Designing with Ultra-Thin Flexible Printed Circuit Boards
Designing with flexible PCBs is not much different from doing the same with rigid boards, except that the designer must account for the mechanical complexity associated with flex circuits. For instance, a flexible PCB can tear if flexed beyond its capability during installation. Therefore, it is very important to create a mechanical model of the PCB and test it for a proper fit, before taking up the electrical design.
Weiner’s World – June 2017
On the way back from Hong Kong last week I had the good fortune of meeting an officer of Allegro Microsystems and enjoyed a wide ranging discussion with him. One of the "take home" items was concern about an expanding shortage of rare earth metals used to make ICs for the burgeoning automotive sensor market. The second was how important the roles of partnering and consortia are in the rapidly advancing autonomous automotive electronic field.
Embedding Components, Part 1
The printed circuit has traditionally served as the platform for mounting and interconnecting active and passive components on the outer surfaces. Companies attempting to improve functionality and minimize space are now considering embedding a broad range of these components within the circuit structure.
