Hi anyone knows what is the minimum copper foil thickness available across the industries to make PCB surface. Intention is to achieve 23 microns of finished copper thickness in a 0.3mm thickness PCB. Ideally if 3 microns plates are available, additional 20 microns plating will definitely help to achieve 20 microns drill wall copper thickness & 23 microns finished copper thickness.

Most boards are fabricated with 1-ounce copper [34.79µm (micron/micrometer)]. Foil more commonly comes in at 33µm or less. Processing reduces this down to 30µm or thinner.

Talk to your board fab about the specifics of your application
