Method for making integrated circuit aluminium panels

摘要

Fabrication of a one side flat aluminum integrated circuit panel consists of preparing the surface of two aluminum alloy sheets, depositing on one of the sheets an anti-weld ink in reserved zones corresponding to the circuit design, roll-bonding the sheets and expanding the channels corresponding to the non-welded zones with a pressurized fluid. One of the sheets is made of series 1000 alloy and the other is made of an alloy of iron and manganese in which Fe+Mn is greater than 0.8 wt %, preferably greater than 1% or even 1.5%. An Independent claim is also included for the continuous fabrication of integrated circuit panels formed from at least three metal strips.
