PACE Technologies PDA-45P8 Premium Diamond Plain-Backed Lapping Film, 45 micron, 8", 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.
• Plain-backed: Require a wet surface for adhesion. Offer superior flatness for precision applications
• Wet the flat lap plate with water or a water/surfactant solution
• Place the plain-backed lapping film on the surface
• Roll out or press out any entrapped air bubbles to ensure full contact
• 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
