Knocking Down the Bone Pile: Basics of Component Lead Tinning

04/02/2025 | Nash Bell -- Column: Knocking Down the Bone Pile
The component lead tinning process serves several critical functions, including removing gold plating, mitigation of tin whiskers, reconditioning of component solderability issues, and alloy conversion from lead-free (Pb-free) to tin-lead or from tin-lead to lead-free for RoHS compliance. We will cover each of these topics in more detail in upcoming columns.

Airbus to Design and Build ESA’s ExoMars Rover Lander Platform

03/31/2025 | Airbus
Airbus has been selected by the European Space Agency (ESA) and Thales Alenia Space (TAS - a joint venture between Thales (67%) and Leonardo (33%)), the ExoMars industrial prime contractor, to build key systems for the ExoMars lander that will safely place the Rosalind Franklin rover on the surface of the Red Planet.

The Chemical Connection: Surface Finishes for PCBs

03/31/2025 | Don Ball -- Column: The Chemical Connection
Writing 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.

PCB007 Magazine: The Essential Guide to Surface Finishes—March 2025

03/17/2025 | I-Connect007 Editorial Team
In the March 2025 issue of PCB007 Magazine, we go back to basics, recount 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. 

Marcy's Musings: The Golden Touch?

03/18/2025 | Marcy LaRont -- Column: Marcy's Musings
Corrosion, adhesion, bonding—the comprehensive issue of surface finish plating is primary for PCB manufacturers and their assembly counterparts. Gold is the standard for many applications, but it is expensive and has its limits. This issue of PCB007 Magazine leads with a deep dive into the various iterations of gold plating by the engineering team at MKS Atotech.
