Evaluating Physical Process Parameters to Improve Copper Plating Distribution

09/11/2026 | Richard Nichols and Marko Mirkovic, GreenSource Engineering
Consistent copper thickness across panels directly affects etching accuracy, conductor geometry, electrical performance, and ultimately, product reliability. It is a persistent manufacturing challenge, and for PCB fabricators serving advanced markets—including RF applications, power electronics, and other high-performance technologies—electrolytic copper plating is one of the most critical process steps. In response, manufacturers typically modify shielding, rectification, or tooling, which may require an expensive hardware change.

Trouble in Your Tank: Pre-electroless Causes of Voids

09/02/2026 | Michael Carano -- Column: Trouble in Your Tank
To support advanced 2.5D and 3D heterogeneous integration, product and motherboard designs are now using higher layer counts. As layer counts increase, plated through-holes (PTHs) become deeper and higher in aspect ratio, making it more difficult to achieve a continuous, void-free copper deposit. Drilling these thicker panels and higher aspect ratio vias adds another layer of complexity. Since there are many potential causes of PTH voiding, I’ll focus on pre-electroless copper causes, including drilling.

Fresh PCB Concepts: Everything Your PCB Supplier Needs Upfront for Quoting

08/27/2026 | Team NCAB -- Column: Fresh PCB Concepts
After more than 40 years in PCB manufacturing, I've come to appreciate that every PCB begins long before the first sheet of laminate enters a press or the first hole is drilled. A PCB’s journey begins with a request for quotation (RFQ). I’ve been involved with documentation practices since the days of 4:1-scaled and Blue & Red-taped mylars. They all underwent photo-reduction and resizing to 1:1-scale film for manufacturing, and this became our tooling package. With new media and technology involved, this process has undergone many changes, but the focus on tooling can never waver. I have learned that the accuracy of the quotation is directly tied to the quality of the information received.
