The Chemical Connection: Reducing Defects in Circuit Board Production

06/04/2025 | Don Ball -- Column: The Chemical Connection
We all agree that in any manufacturing process, reducing defects in your product induced during manufacture (aka increasing yields) is a good thing. Doing so, however, can be a source of contention and frustration. I don’t pretend to be an expert in this field, because most of my work involves feasibility studies for new concepts or testing improvements made to existing equipment. High yields were usually not a factor; it’s simply about having enough data to prove or disprove a concept or seeing whether improvements to equipment design actually work. However, here are some observations I made visiting quality shops where high production at high yields was important.

Efficiency Unleashed: Breaking Down Lean and Six Sigma

06/02/2025 | Marcy LaRont, PCB007 Magazine
As a child in the late 1970s, I lived in Fremont, California, near the GM automotive manufacturing plant. At the time, GM had a terrible reputation for producing poor quality cars that were dwindling in popularity. I toured the GM plant while in elementary school. Each child received a pair of safety glasses before our group was escorted around the plant with our teacher. I remember seeing the car pieces on the line, and workers using blow torches to assemble the car together.

Marcy’s Musings: The Relentless Pursuit of Perfection

05/16/2025 | Marcy LaRont -- Column: Marcy's Musings
Few things in this world are or will ever be perfect. For me, perfection might look like the vivid colors that only Mother Nature can create, the birth of a child, and the inner workings of the human brain. But all else in this physical, tangible world is, in one way or another, inherently flawed. Even the “flawless” diamond is more about the sheer awe and beauty of beholding near-perfection than perfection itself. In many ways, this truth provides great texture and diversity to our world. Yet, we still strive for perfection, and it’s in this that we learn and achieve higher heights than we otherwise would have.
