In fact, material selection requires consideration of the actual application scenario and processing conditions. I've encountered cases where pursuing a low Dk value led to board warping, only to find that medium-loss materials performed better. The essence of RF design lies in balance; sometimes adjusting trace width is more effective than replacing it with a high-end board. What's truly important is understanding the actual performance of materials under temperature and humidity changes; this experience is far more valuable than..."}
