94 PCB007 MAGAZINE I NOVEMBER 2024 In this interview, Rich DePoto of Uyemura pro- vides a deep overview and explanation of Reduction-assisted Immersion Gold (RAIG) and direct immersion gold (DIG) technology, and their applications and benefits when compared to traditional final finishes. He delves into the intricacies of elec- troless nickel cor- rosion and "black pad," exploring its causes, conse- quences, and the measures that can be taken to miti- gate this problem. DIS recently opened a new facility in New York state, pro- viding an abun- dance of oppor- tunity for DIS and its customers. Jesse Ziomek, president of global business development at DIS, dis- cusses the strides made in tech innova- tion and automation, expanding DIS's cus- tomer portfolio to address the challenges its customers have been grappling with, and entering new markets such as rigid- flex and flexible PCBs. As a supplier of PCB wet processing equipment, we inevitably find ourselves involved in helping customers solve sudden process prob- lems that may or may not be caused by equipment malfunctions. For the most part, equipment problems are relatively easy to identify and repair: sensors for chemistry and equipment control, clogged noz- zles and filters, leaks in the plumbing, etc. But what happens when the equipment checks out and the problem is still there? Unlocking Advanced Circuitry Through Liquid Metal Ink PCB UHDI technologist John Johnson of American Standard Circuits dis- cusses the evolving landscape of electronics manufacturing and the criti- cal role of innovation, specifically liquid metal ink technology, as an alter- nate process to traditional metallization in PCB fabrication to achieve ever finer features and tighter tolerances. The discussion highlights the benefits of reliability, efficiency, and yields as a tradeoff to any increased cost to run the process.
