This method is almost the same as the method of manufacturing multilayer boards by using the through-hole method. After Japan stepped into this field in 1963, various ideas and manufacturing methods related to multi-layer boards were gradually spread all over the world. The following is about 14 Layer High TG PCB related, I hope to help you better understand 14 Layer High TG PCB.
