Double sided PCBs unlock more layout space, reduce layers, improve signal integrity & offer flexible arrangements. For rapid prototyping, dual layer boards accelerate progress.
Double Sided PCB
Single and double-sided printed circuit boards share identical material make-up: FR-4, a form of fiberglass mixed with epoxy. Which PCB you pick depends on your needs and requirements. Sometimes single-sided PCBs are more suitable for project design as compared to double-sided PCBs and vice versa.
