56 PCB007 MAGAZINE I MAY 2021 Introduction While this month's column departs some- what from my usual topics, the subject matter is no less critical. As someone who has been troubleshooting and problem solving for many years, I have found that the process and tools are extremely important. I was asked to consider addressing the topics of optimizing business processes and strategy, process optimization, and training your team. I believe developing critical thinking skills will help engineers troubleshoot technical issues and bring them to a quick resolution as this is certainly a good lead-in to training your team. Troubleshooting 101 is should come as no surprise to those of you who read my monthly columns or have met me in your circuit board facility: Remem- ber, time is money. e longer a problem goes unresolved the more money, and certainly fu- ture customer goodwill, can be lost. When be- ing called on to solve technical issues—wheth- er it be a delamination situation, copper plat- ing failures, or solderability defects—I stress a few simple rules: 1. Walk the line and watch the operators in action. 2. Review documented work procedures. 3. Check rinse water quality and dwell times—are you rinsing away the contaminants or simply dragging them along with the boards to the next critical process? 4. And the biggest sin: "Yes, everything in the chemistry is being controlled per datasheet."
