Current IssueThe Essential Guide to Surface Finishes
We go back to basics this month with a recount of a little history, and look forward to addressing the many challenges that high density, high frequency, adhesion, SI, and corrosion concerns for harsh environments bring to the fore. We compare and contrast surface finishes by type and application, take a hard look at the many iterations of gold plating, and address palladium as a surface finish.
It's Show Time!
In this month’s issue of PCB007 Magazine we reimagine the possibilities featuring stories all about IPC APEX EXPO 2025—covering what to look forward to, and what you don’t want to miss.
Fueling the Workforce Pipeline
We take a hard look at fueling the workforce pipeline, specifically at the early introduction of manufacturing concepts and business to young people in this issue of PCB007 Magazine.

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.

Connect the Dots: Stop Killing Your Yield—The Hidden Cost of Design Oversights
04/03/2025 | Matt Stevenson -- Column: Connect the DotsI’ve been in this industry long enough to recognize red flags in PCB designs. When designers send over PCBs that look great on the computer screen but have hidden flaws, it can lead to manufacturing problems. I have seen this happen too often: manufacturing delays, yield losses, and designers asking, “Why didn’t anyone tell me sooner?” Here’s the thing: Minor design improvements can greatly impact manufacturing yield, and design oversights can lead to expensive bottlenecks. Here’s how to find the hidden flaws in a design and avoid disaster.
Real Time with... IPC APEX EXPO 2025: Tariffs and Supply Chains in U.S. Electronics Manufacturing
04/01/2025 | Real Time with...IPC APEX EXPOChris Mitchell, VP of Global Government Relations for IPC, discusses IPC's concerns about tariffs on copper and their impact on U.S. electronics manufacturing. He emphasizes the complexity of supply chains and the need for policymakers to understand their effects.
The Chemical Connection: Surface Finishes for PCBs
03/31/2025 | Don Ball -- Column: The Chemical ConnectionWriting about surface finishes brings a feeling of nostalgia. You see, one of my first jobs in the industry was providing technical support for surface cleaning processes and finishes to enhance dry film adhesion to copper surfaces. I’d like to take this opportunity to revisit the basics, indulge in my nostalgia, and perhaps provide some insight into why we do things the way we do them in the here and now.
NUS Physicists Discover a Copper-free High-temperature Superconducting Oxide
