Alkaline Zincate Pretreatment

This process uses a double zincate chemistry that deposit zinc on the aluminum pads and then removes it and re-deposits a second thinner layer of zinc. This technique reduces the amount of zinc on the surface the second time which enhances adhesion by reducing the zinc trapped at the interface. Zinc that is trapped at the interface produces a brittle interface and reduced adhesion

Another important reason for using alkaline zincate is the ability to process pure aluminum. Pure aluminum has less electrical resistance and is used commonly in higher performance devices. Alkaline zincate is capable of oxidizing the pure aluminum surface and depositing zinc whereas the Acid zincate is far less aggressive to the passive aluminum surface and deposits zinc at a slower rate.

Benefits

 Improved Adhesion on pure Aluminum

 Increased removal of Aluminum on Pad

 Simple Operations and Controls
