Through cases such as insufficient resin via curing leading to impedance abnormalities in medical device boards and signal loss due to thermal expansion coefficient deviations in communication base station boards, the article reveals easily overlooked details in high-end PCB production. It discusses how systematic control through laser positioning and 2D measurement can improve yield rates to over 98%. These experiences tell us that producing high-quality HDI boards requires not only advanced equipment, but also..."}
