Selecting FR4 Alternatives of PCB Substrate Materials for Multilayer Boards
PCB Design EngineersSometimes, it pays to go against the grain. FR4 substrates are by far the most popular option you'll find from fabricators, and each fabricator has their preferred supplier. However, you might want to pursue alternative PCB substrate materials for a multilayer board. Although there are multiple PCB laminate material manufacturers, the broad class of available substrates is somewhat limited.
