  Highlights of the latest issue of PCD&F/Circuits Assembly:

  • The heat is on. Thermal interface materials (TIM) are used between components to help with heat dissipation. Claire Wemp, Ph.D., a thermal applications engineer at DuPont, discusses the use of TIMs, as well as her involvement in the Society of Women Engineers.
  • A plethora of pitches. The evolution of integrated circuit package technology drove the electronics industry to its present state, but a closer look at the past reveals missed opportunities to create a more coherent set of IC standards, as well as lessons to be learned for future choices to improve design efficacy and product performance and reliability.
  • Cpk or Ppk? A look at using both capability indices. . Summary statistics can be misleading, but in different ways. Always graph your data.
  • Selectively assembling high-value components based on warpage in order to improve reliability. Surface warpage, or flatness, is an established source of reliability issues in surface mount devices, particularly when these surfaces are considered as they warp due to heat generated in production or real-world use. While measuring samples for thermal warpage is a common practice, an experimental concept is presented based on measuring warpage on SMD devices and the PCB landing areas where they would attach in assembly, then deciding which sample to place on which PCB.
  • Managing library and design data.Automating data maintenance and revision control.
  • Copper vs. CuNI for flexible heater elements. Voltage, heater size and material costs all factor into the decision process.

  Reading Material

  Highlights of the April issue of PCD&F/Circuits Assembly:

  • Understanding electroless nickel thickness in ENIG and ENEPIG. Accurate measurement of the electroless nickel layer thickness is possible if a user corrects for density changes caused by the inclusion of phosphorus in the nickel deposit in a specific sample.
  • ‘A solution for anybody in North America’. APCT’s recent acquisition of ACI nearly doubles APCT’s annual revenue to $200 million, and makes the company the third largest among PCB fabricators in North America. APCT head Steve Robinson discusses the acquisition and his vision for the company’s future.
  • Early detection of failures caused by corrosion on components. Corrosion is the most predominant failure mode in electronic products, and corrosion present in solder leads before the soldering process a devastating effect because they become a breeding seed of the corrosion epidemic. A demonstration of how components with corrosion and contamination in the soldering leads can be detected early during production and avoided.
  • Real-time x-ray video imaging of pb-free solders under simulated SMT reflow. Two current baselines and seven next-generation lead-free solder paste alloys are observed using radiographic imaging during SMT reflow to find the best LF alloys for the next phase for production prototypes.

  • Permittivity vs. permeability: What’s the difference? Some areas of physics have considerable impact on our designs. Here we look at two physical properties of the dielectrics we work with, and why they are important to understand.
  • How interconnects work: characteristic impedance and reflections. Reflections in an interconnect degrade the transmitted signal, which may cause link failure. How to solve for the reflections caused by transmission line characteristic impedance and termination impedance mismatch.
  • A quick fix for fillet starvation. A typical problem for via-in-pad design is the creation of seemingly “starved” fillets when the via sucks up solder from pads at terminals during reflow. A simple solution to this problem is detailed.
  • Aligning six sigma tools with process reality. Identify the areas of variance in stencil design and adjust SPI programming accordingly.

  CHAPTER NEWSLETTER – December 2022

  Hello members!

  It’s been a couple months since we’ve last communicated. We hope the usual rush to complete any end-of-year tasks is going well and your holiday season is a safe and happy one.

  There’s a lot to catch up on.

  In October, PCEA celebrated a very successful PCB West in October, its first since acquiring the industry-leading technical conference and trade show from UP Media Group in January. Conference registration was at its highest point in more than 10 years, nearly 2,000 industry professionals registered for the exhibition, and more than 85 exhibitors filled the sold-out show floor. Keynoter Dr. Brian Toleno, manager, Applied Materials at Meta’s Reality Labs, gave a scintillating presentation on the opportunities the metaverses offer not just for users but for developers of computing devices. He looked at the novel innovations in materials and production that will be needed for printed circuit designs to meet the requirements for weight, size and functionality. “Games alone won’t drive AR/VR,” Toleno noted. “The next generation of Zoom will be 3-D avatars.”

  At PCB West, we also held our annual meeting and introduced our 2023-24 board of directors, as elected by the membership: Stephen Chavez, Tomas Chester, Michael Creeden, Doug Dixon, Tara Dunn, Gary Ferrari, Justin Fleming, Richard Hartley, Scott McCurdy, Anaya Vardya, Susy Webb and Eriko Yamato.

  The board then voted on the officers for the term: Chavez, chairman; Dunn, vice chairman; Fleming, secretary. Committee chairs include Chester, Education; and Creeden, Membership.

  Also during the meeting, we recognized Mike Creeden with the first PCEA Leadership Award, for his lifetime service in the pursuit of educating and training PCB design engineers. Mike, who was PCEA’s first vice chairman, was instrumental in the launch of PCEA and the negotiation to acquire the assets of UP Media Group, including PCB West.

  And Scott McCurdy was recipient of the first PCEA Membership Award. Scott was PCEA’s first Membership Committee chairman, and has been president of the Orange County chapter of the PCEA since its inception. Meanwhile, we have begun preparations for PCB East and PCB West. Read more in the National news below.

  We have a new managing editor for PCD&F/Circuits Assembly. In October we welcomed Tyler Hanes to our staff. Tyler has a journalism degree and a experience in regional papers and trade groups. He is based in Alabama and has already attended his first industry event: PCB Carolina.

  Finally, we have a new section on Printed Circuit University dedicated to PCEA members. In addition to its paid content, PCU has added a section with free white papers and videos for any PCEA members. Learn more at PrintedCircuitUniversity.com.

  ONTARIO, CANADA – On Nov. 24 we held a virtual Lunch’ n’ Learn featuring Ata Syed, field application engineer at PFC Flexible Circuits. Syed is starting a multipart series on flex circuits. In this first session, he covered the five “W’s” of flex technology:

  • What is flex?
  • Why use flex?
  • Who should know flex?
  • When to use flex
  • Where to use flex

  To view the presentation click here.

  RTP – The RTP Chapter held its annual PCB Carolina in November and by all accounts it was a success. The show floor was sold out and registration was its highest ever, with more than 1,000 professionals registered. Kathy Joseph, host of the Kathy Loves Physics YouTube channel and author of “The Lightning Tamers,” keynoted the event. Her presentation, “The Origins of the World’s Electricity,” chronicled names and stories – some familiar, some less so – to tell the story of the birth of electricity and explain quirks of the world’s electrical systems, such as the reasons why most countries use around 220V and 50Hz for their main voltage while the US and Canada use around 120V and 60Hz.

  NATIONAL NEWS –

  Membership committee. This month Mike Creeden led a leadership session for existing and startup chapters. He gave updates on the association, strategic plan and education committees, and events planned for 2023. Q/A was a big part of the session. The session was recorded for chapter leaders who could not make the live call.

  Education committee. The abstracts deadline for PCB East 2023 has ended and we have received more than 50 abstracts. The Conferences task group is led again by Rick Hartley. A PCEA Conference Abstract Selection Process will be used for the first time for this event. The target date for releasing the three-day technical program is Jan. 3, and PCB East takes place May 9-11 in Boxborough, MA.

  Reading Material

  Highlights of the December issue of PCD&F/Circuits Assembly:

  • Updating an existing design. Not all designs start from scratch. Some files come from the client. And sometimes, the schematic and PCB layout get out of sync.
  • Clocking a PCB design. Aligning signals to attain perfect synchronicity.
  • Basics of polymers for thermal management of electronic devices. A comprehensive thermal management approach not only includes using the right TIM materials in combination with heat sinks, heat pipes, fans and heat spreaders, but also includes a good thermal management strategy that starts during the design phase.
  • Addressing low-temperature rework concerns. The inherent brittleness of bismuth inhibits the manufacturing of fluxed cored wire. One solution involves use of a high-bismuth solid wire solder with an external flux. Another approach is to use traditional SAC-flux cored wire solder to rework low-temperature solder joints.

  Reading Material

  Highlights of the September issue of PCD&F/Circuits Assembly:

  • ECAD industry wages are rising. (Tell me something I didn’t know.) Results of our annual PCB designer/design engineer salary survey.
  • Why I4.0 and reshoring go hand in hand. According to research firm IDTechEx, it’s only a matter of time before an array of sensors and cobots spur far greater automation and flexibility.
  • Tacking material for power module assembly. A no-flux reflow process can mitigate residue issues in vacuum soldering and avoid additional cleaning steps that add process time and cost.
  • Ensuring proper alignment of layers and components on a PCB. Why a tooling hole remains the answer for an end-to-end process.

  CHAPTER NEWSLETTER – August 2022

  Hello members!

  Our local chapters are returning to in-person meetings and the early feedback is very positive. Peer-to-peer networking and mentorship is at the very core of PCEA’s mission. The chapters exist to instruct, inform and connect designers and engineers across the electronics supply chain. They offer a wide variety of technical topics, plus access to colleagues who might serve as future go-to’s for technical and professional advice.

  We strongly encourage you to take advantage of the local chapters or even help start one in your area.

  Our scheduled free 90-minute webinar on EMI/EMC by Harry Kennedy Jr. has been postponed to Aug. 11. See Other Educational Opportunities below for more details.

  The technical program for PCB West 2022 features nearly 50 presentations and more than 110 hours of in-depth electronics engineering training. Professional education hours are offered for the technical conference, which can be used for maintaining professional certifications and for corporate training program requirements.

  Here are just a few of the topics:

  • Best Practices for Hardware IP Reuse
  • Power Integrity and Decoupling
  • Understanding PCB Fabrication Processes
  • PCB Design for Engineers
  • Understanding Basic High Speed PCB Layout
  • PCB Layout of Switch Mode Power Supplies
  • RF and Microwave PCB Design

  Keep in mind that PCB West also feature two day-long tracks of free sessions, which coincide with the (free) exhibits on Octover 5. The conference takes place October 4 to 7 at the Santa Clara (CA) Convention Center and features classes for every level of experience, from novice to expert. Registration is now open at pcbwest.com.

Local Chapters

Just a few updates this month. Please forward your chapter news to pcea@pcea.net for inclusion on our website and in future newsletters.

ORANGE COUNTY, CA – We held our first in-person Lunch ‘n Learn meeting event in 2½ years on July 26 in Santa Ana, CA. It was hosted by Insulectro and attracted an audience of 44 designers, engineers, and fabricators to listen to three educational presentations.

Two topics were presented by Chris Hunrath, vice president of technology at Insulectro.

Signal integrity applications in layout was very detailed in applying SI theory to a layout, where he covered EM fields, laminates, copper profile, uninterrupted GND return path, impedance discontinuities from your routing, and proper shielding.

Advanced via solutions using Ormet pastes was also presented by Chis, who had some excellent slides discussing applications for addressing Z-axis interconnects for multi-lam HDI, backdrill elimination, solving high aspect ratio plating on high layer count boards, and any-layer-via usage. A variety of different stack-up constructions were shown which got many designers thinking how this sintered metal process could bring a variety of solutions to the designer. This is a mature process that could provide improved cost and performance in many applications in comparison to the standard PCB multilayer process.

Chris will also present at PCB West this fall.

Overcoming flex design challenges was presented by Geoffrey Leeds, CID, flex product manager at Insulectro. In his presentation, Geoffrey spoke about overcoming flex design challenges by understanding the building blocks; pitfalls to avoid during layout; dynamic vs. static design constraint; and the proper materials and their applications. Many designers in the audience were unfamiliar with flex circuit design practices, so this presentation was a well-received learning experience.

Compared to webinars, the in-person experience allowed for many questions from the audience which elicited answers from the presenters, as well as fabricators and others in the room that had insightful responses that added to the knowledge exchange. The Lunch ‘n Learn meeting wrapped up the drawing for eight raffle prizes totaling over $1,000 including a Footprint Expert software license from PCB Libraries, restaurant gift cards from Freedom CAD Services, and Amazon gift cards from Siemens EDA and Insulectro.

SILICON VALLEY – We will hold our next meeting Aug. 4 from 11:30 to 1:30 at Siemens EDA (Mentor Graphics) in Fremont, CA. This is a Lunch ‘n Learn, featuring Carl Schattke, whose presentation is The A+ PCB Outline Drawing.

This presentation will save design teams time and money and prepare them for optimal communication for a fast start to the design process. All the important points of the PCB outline drawing will be reviewed, so attendees will know what to look for and what to ask for when creating or receiving an outline drawing. The details of what should be on the outline drawing will be shown and listed so attendees will gather the proper information.

Emphasis will be placed on design details, including dimensions, tolerancing, hole call-outs, component marking, and critical features for manufacturing and cost control. Keep-out designations, height requirements. Drawing formats and outputs. The author intends to leave attendees a much higher level of understanding the critical aspects of starting a PCB design the right way.

This is sponsored by Siemens EDA. Please RSVP no later than 4 pm on Aug. 1. All attendees must preregister here.

OCTOBER ELECTIONS – A ballot for the October election of the board of directors has been circulated via email. All PCEA members in good standing are eligible to vote for the board of directors. PCEA members may vote for up to 12 individuals for the board. Please use the link here access the ballot. Directors are nominated by the nominating task group and voted on by the general membership.

Other Educational Opportunities

EMI/EMC – Join Harry Kennedy Jr. August 11 (note new date) for a special 90-minute webinar on EMI/EMC. If you are not a signal integrity (SI) expert, the thought of EMI/EMC issues might bring you chills. As PCB simulation tools continue to improve, it’s important to incorporate signal integrity checks early in the design process. Instead of waiting for the analysis results after laying out your PCB, why not implement best practices into your verification process.

This noncommercial webinar, free to all PCEA members, will look at common EMI/EMC issues, and how they can be traced back to design best practices. It will also look at how to can use rule-based verification to automatically check for indicators, saving time and money.

This workshop is meant for beginner to mid-level PCB designers and SI engineers. The purpose of this workshop is to add a skillset that helps free up the time of the SI expert. This workshop also encourages users to add best practices into their current workflow by adopting this methodology. This workshop can be done with generic DfE and DfM tools. Register today!
