Current IssueInner Layer Precision & Yields
In this issue, we examine the critical nature of building precisions into your inner layers and assessing their pass/fail status as early as possible. Whether it’s using automation to cut down on handling issues, identifying defects earlier, or replacing an old line...
Engineering Economics
The real cost to manufacture a PCB encompasses everything that goes into making the product: the materials and other value-added supplies, machine and personnel costs, and most importantly, your quality. A hard look at real costs seems wholly appropriate.
Alternate Metallization Processes
Traditional electroless copper and electroless copper immersion gold have been primary PCB plating methods for decades. But alternative plating metals and processes have been introduced over the past few years as miniaturization and advanced packaging continue to develop.

EU Commission Launches Stakeholder Consultation on RoHS Exemptions
September 20, 2017 | IPCEstimated reading time: 1 minute
The European Union (EU) Commission launched a four-week stakeholder consultation on DRAFT Delegated Directives for exemptions:
- 6(a) Lead as an alloying element in steel for machining purposes and in galvanized steel containing up to 0.35% lead by weight
- 6(b) Lead as an alloying element in aluminum containing up to 0.4% lead by weight
- 6(c) Copper alloy containing up to 4% lead by weight
- 7(a) Lead in high melting temperature type solders (i.e. lead-based alloys containing 85% by weight or more lead)
- 7(c)-I Electrical and electronic components containing lead in a glass or ceramic other than dielectric ceramic in capacitors, e.g. piezoelectronic devices, or in a glass or ceramic matrix compound
- 18(b) Lead as activator in the fluorescent power of discharge lamps containing phosphors
- 24 Lead in solders for the soldering to machined through hole discoidal and planar array ceramic multilayer capacitors
- 34 Lead in cermet-based trimmer potentiometer elements
The consultation closes on October 17, 2017.
IPC, in conjunction with an international industry stakeholder group, applied for more than a dozen exemption extension requests under the EU RoHS Directive. The RoHS2 Directive dictates expiration dates for all exemptions granted and several critical to the electronics manufacturing industry were set to expire by July 21, 2016. However, all exemptions for which industry submitted a renewal application will not expire until the EU Commission completes the current ongoing review of the applications.
Throughout the process, IPC and several member companies provided important technical information in order to ensure the extension requests are robust and scientifically sound. IPC reviewed all extension requests and provided important feedback that resulted in credible material submitted to the EU Commission.
IPC’s EHS Committee and RoHS Exemptions Task Force will review the draft delegated acts and develop a response to the stakeholder consultation. IPC member companies are also encouraged to comment directly to EU Commission through their website.

Designers Notebook: Impact of Advanced Semiconductor Packaging on PCB Stackup
01/07/2025 | Vern Solberg -- Column: Designer's NotebookTo accommodate new generations of high I/O semiconductor packaging, printed circuit board fabrication technology has had to undergo significant changes in both the process methods and the criteria for base material selection and construction sequence (stackup). Many of the new high-function multi-core semiconductor package families require more terminals than their predecessors, requiring a significantly narrower terminal pitch. Interconnecting these very fine-pitch, high I/O semiconductors to the PCB is made possible by an intermediate element referred to as an interposer.
BOOK EXCERPT: The Printed Circuit Designer’s Guide to... High Performance Materials, Chapter 4
01/02/2025 | I-Connect007In Chapter 4, Michael Gay discusses the two main types of copper foil used for PCB boards today: electrodeposited (ED) foil and rolled annealed (RA) foil. He also explains the pros and cons of each, and provides an update of the latest innovations in copper foil technology.
Connect the Dots: Designing for Reality—Solder Mask and Legend
01/02/2025 | Matt Stevenson -- Column: Connect the DotsIn the previous episode of I-Connect007’s On the Line with… podcast, we discussed the strip, etch, and strip process. At this point, we have a functioning board, but we still need to protect the PCB from environmental effects and document the circuit components. This brings us to the solder mask and legend phase of production.
Global PCB Connections: Following DFM Rules Leads to Better Boards
12/18/2024 | Jerome Larez -- Column: Global PCB ConnectionsAs a PCB field applications engineer, ensuring smooth communication between PCB designers and fabricators is one of my frequent challenges. A critical part of that dialogue is design for manufacturing (DFM). Many designers, even experienced ones, often misunderstand or overlook important DFM considerations. They may confuse design rules with manufacturing minimums, leading to technically feasible designs that are difficult or costly to produce. In this column, I will clarify some common DFM guidelines and help designers understand the difference between “design rules” and “minimums” while sharing best practices that will simplify the production process and ensure the highest quality PCB.
Sayonara to the Last Standing Copper Foil Plant in North America
12/17/2024 | Marcy LaRont, I-Connect007In July 2021, PCB007 Magazine published an interview with Michael Coll and Chris Stevens of Nippon Denkai about the new acquisition by Nippon Denkai of the last-standing ED foil manufacturer in North America. The plant in Augusta, Georgia, was formerly owned by Oak Mitsui, Inc. and had been purchased by Nippon Denkai the previous March, after which significant investment was made with the expectation of providing more jobs.
