Multilayer PCB — technical-support envelope
Manufacturer reportedAoshikang’s technical-support table specifies a 24-layer ceiling, aspect ratio up to 21:1 and ±8% impedance tolerance. It lists backdrill stubs of 2–10 mil and signal-loss methods including SET2DIL, Delta-L and TRL. The separate “24+” heading does not establish a higher numerical production limit.
Technical-support table says 24L while another heading says 24+. Only the explicit table limit is used; no lower layer bound is assumed.
