This article shares my comparative observations of LDI technology versus film processes, inkjet versus silkscreen printing, and flying probe testing versus traditional test fixtures. My experiences with high-frequency board impedance deviation and character detachment have taught me that process selection must be tailored to the specific application scenario, rather than simply prioritizing speed. I hope these experiences can provide a reference for colleagues in balancing efficiency and quality.
