Aluminum Base PCB Aluminum is the world’s most abundant metal and is the third most common element comprising 8% of the earth’s crust. The versatility of Aluminum makes it the most widely used metal after steel.
Aluminum is derived from the mineral bauxite. Bauxite is converted to Aluminum oxide (alumina) via the Bayer Process. The alumina is then converted to Aluminum metal using electrolytic cells and the Hall-Heroult Process. Uniwell has served many customers with aluminum PCB, we have much experience.
