Abstract
A slider for a disc drive assembly may be attached to various substrates during manufacture and installation in the disc drive assembly. In some examples, a slider attachment system includes a substrate, a first diffusion barrier layer formed over the substrate, a first solder-wettable protection layer formed over the first diffusion barrier layer, a second diffusion barrier layer formed over the first solder-wettable protection layer, and a second solder-wettable protection layer formed over the second diffusion barrier layer. The first and second solder-wettable protection layers may be formed of a material that is inert to a chemical etchant that can chemically dissolve the diffusion barrier layers. In use, solder may be applied to the second solder-wettable protection layer to wet and dissolve the layer. If the substrate needs to be detached and reattached, etchant can chemically dissolve the second diffusion barrier layer to expose the first solder-wettable layer for reattachment.
