Technical Data
November, 2005
Product Description
Precision coated SiO2 mineral coating on a polyester film used in the final step in
fiber optic connector polishing. Produces high quality connectors. 3M offers two
products tailored for different process requirements. Available with and without PSA
(Pressure Sensitive Adhesive).
3M™ Lapping Film 863X (869X with PSA)
– Provides super fiber height control, but polishes more slowly than 863XW.
– For use on most polishing machines and fixtures, including machines that run at
higher speeds and higher pressures.
3M™ Lapping Film 863XW (869XW with PSA)
– Has a higher mineral content than 863X, making it more aggressive for faster
polishing.
– Designed for use on machines that run at lower speeds and lower pressures. Also
for use on IPC (Individual Pressure Control) fixtures that allow connectors to
float independently and allow lower machine pressure.
Applications
