QUESTION:
Why is etching important in Chemical Mechanical Planarization of MT ferrules?
ANSWER:
The MT plastic material requires fibers to protrude between 1 to 3.5 microns in height. The only way to achieve this is to etch away the thermoset or thermoplastic material from the fibers.
Remember, the primary task of CMP coated flock pile pads is to etch away the substrate material, leaving the fibers at a specific, controllable protrusion.
The secondary task is to provide a good polish to the glass fibers, so they meet industry requirements for visual standards and optical transmission.
