In this issue, we examine wet processes and how to obtain a better degree of control that allows usable data to guide our decisions and produce consistently higher-quality products.
Don’t Just Survive, Thrive
If we are to be relevant and prosper during these next critical decades in electronics, we must do more than survive. As an industry, we can and must thrive. In this issue, our contributors explore these concepts meant to help you take your business to the next level.
Material Matters
Materials management is nuanced, multifaceted, and requires a holistic systems approach for business success. When building high mix, low volume, and high technology, managing materials and overall cost containment are even greater challenges.

Matrix Materials Support Ultra-Long Flexible Circuits Applications
May 31, 2018 | MatrixEstimated reading time: 1 minute
The market for long flexible printed circuits continues to grow rapidly. The performance and high reliability of flexible circuits over traditional hard wiring and cabling continues to expand into new applications in medical equipment, automotive, aerospace and defense applications. One key challenge for manufacturing ultra-long circuits has been obtaining the custom sized long panels or flexible circuit roll materials needed to fabricate these circuits.
Matrix is pleased to announce that it can support long flexible circuit applications with either copper clad flex materials in roll form or custom made long flex material panel sizes made with the leading Panasonic Felios and Matrix Plus brand of flexible circuit materials. Matrix maintains a wide range of roll materials in stock and can provide custom panels on a quick-turn basis from the flex materials conversion center located in our Santa Clara, California location.
“We are pleased to take a leadership role in supporting this exciting market with a growing list of customers that are using proprietary roll to roll and long circuit manufacturing processes.” stated Bob Berg, Matrix VP of Sales and Marketing.

Connect the Dots: Designing for Reality—Electroless Copper
08/28/2024 | Matt Stevenson -- Column: Connect the DotsRoll up your sleeves because it's time to get messy. In a recent episode of I-Connect007’s On the Line with… podcast, we discussed electroless copper deposition. This process deposits a copper layer into the through-holes and vias of what will eventually be a PCB. Electroless copper deposition feels like a black box to many people. It sort of looks like a black box, too. The boards go in one side, come out the other, and emerge differently. So, let's crack open that black box and look inside.
Maximizing ROI Through Better Wet Process Control
08/20/2024 | I-Connect007 Editorial Team“When things get out of control, the variation in your wet process begins,” says Mike Carano,. “Just because they look like good boards and may even pass electrical test, it does not necessarily mean you have good boards. Once the chemistry is headed toward the right or left side of the process control parameter cliff, the plating is compromised. If the copper is thinner than it should be, when the customer puts it into service, the board may fail after 500 cycles vs. the requisite 1,000 or 2,000 cycles. The root cause issue is that you plated 7/10ths of a mil of copper instead of one-mil of copper because you were not controlling your process. The fact that you passed your own electric test becomes inconsequential.”
The Chemical Connection: Controlling an Alkaline Etch Bath With Low Copper Loading
08/07/2024 | Don Ball -- Column: The Chemical ConnectionThis month, I wanted to continue my discussion on how much process control is actually needed for high-density circuit production. However, in the last month, I have been called on to help with a specific process control problem: how to control an alkaline etch bath when you’re not etching much copper. This problem has been cropping up more frequently as smaller shops (and a few larger ones) concentrate on low-volume, high-value plated through-hole panels such as prototypes, resistor cores, etc.
