PACE Technologies PDAA-45P10 Premium Diamond PSA-Backed Lapping Film, 45 micron, 10", Pack of 5 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.

Features:

• Diamond lapping films: Ideal for hard, brittle materials like ceramics, silicon, and optical components. Excellent for SEM and TEM analysis with reduced relief compared to cloths.
• PSA-backed: Self-adhesive for quick installation. More convenient but may provide slightly more flexibility.
• Ensure the lapping plate surface is clean and dry
• Place the PSA-backed lapping film on the surface, pressing firmly from center outward
• Apply necessary lubricant (water, diamond lapping film lube, or appropriate polishing fluid)
• Begin polishing with lower force (5-10 lbs per sample) to avoid tearing film
• Use counter-rotation at moderate speeds (100-150 RPM head/base)
• Clean specimen and film for final 10-15 seconds of polishing cycle
• Clean and dry specimens thoroughly before proceeding to next step
