5 impedance tolerance custom backdrilled pcb

Custom Backdrill PCB (Stub Removal) Huayihai fabricates custom backdrilled PCBs for high-speed designs. Backdrilling removes the unused portion of a plated through-hole — the stub — after lamination, so backdrilling removes the unused portion of a plated through-hole after lamination, reducing the reflections and signal degradation caused by via stubs in high-speed channels. Backdrilling supports cleaner impedance...
