In the production and processing of resistive touch screens and liquid crystal displays, Newton’s rings (also referred to as rainbow patterns by some manufacturers) appear like a ghost haunting the workshop. If not careful, they can unexpectedly emerge during production and customer use, causing considerable distress for the process engineers managing the site. This is … Read more
12-layer boards achieve high-density wiring through fine stacking (such as FR-4 substrates or polyimide insulation layers), combined with blind and buried via designs to reduce signal interference. In industrial control applications (such as automation equipment or power management modules), their advantages include multi-power layer distribution, impedance control (±10% tolerance), and optimized thermal management. However, the … Read more
Hello everyone, I am A-Zhe, a process engineer at a company that produces high-performance copper-clad laminates. Today, I want to share with you a tough battle our team fought last year— how we turned a nearly invisible “small pit“ on our product, which was costing us hundreds of thousands each month, into a “golden signboard“ … Read more
