PACE Technologies ALO-1203PB-3 12" Diameter 3 um Alumina Lapping Film (Plain-Backed) - 100 pcs.

Lapping films are precision-coated abrasives that produce extremely flat surfaces across diverse materials. They're ideal for semiconductor dies, fiber optics, ceramic capacitors, optical components, and hard drive read-write heads.

These films feature a durable polyester backing (typically 3 mils) with abrasives fixed using an epoxy or adhesive binder. The uniform abrasive distribution ensures consistent surface finishes, even across varying material hardnesses.

Alumina lapping films: Used for final polishing due to their hardness and consistency. Effective for non-ceramic substrates and maintaining flatness in electronic packages.

Plain-backed: Require a wet surface for adhesion. Offer superior flatness for precision applications.
