cleaning critical surfaces
UltraSOLV®
Wipers and Sponges
Description
UltraSOLV® is a highly absorbent, Class 10 Wiper constructed from a naturally reticulated, hydrophilic, polyurethane foam. Using Foamtec's patented cleaning process and foam technology, UltraSOLV® Wipers are ideal for cleaning critical tools and assemblies. Available as a sponge for use with UltraSOLV® ScrubPADs on wet cleans.
Advantages
 |
The unique abrasion resistance and conformable characteristics of UltraSOLV® allow it to clean rough, coarse and bead blasted surfaces that will snag traditional polyester wipers. |
|
Low levels of particle generation, ionics, organics, lot-to-lot consistency and fiber free construction combined with unsurpassed contamination removal properties make it the ideal tool for the cleaning of critical process equipment. |
|
Sponge-like absorbency and rinsing characteristics offer the opportunity to significantly reduce wiper usage and hazardous waste generation in equipment PM's. |
|
Excellent static dissipative and tribocharging properties allow for safe cleaning of static sensitive assemblies, such as wafer transfer chambers in vacuum tools. |
Applications
Performing wet cleans and PMs on vacuum based process equipment in the Semiconductor, Disk Drive and Flat Panel Display industries.

Methods of Use
To maximize usage of Wiper: |
|
a) Use with IPA Solvent: Apply a thin stripe of IPA, using a needle-nosed squeeze bottle, to the area just behind the rounded fold. Do not over wet Wiper. |
|
b) Use with DI Water: Fully saturate by applying a quarter-sized amount of DI Water to the center of an unfolded Wiper, wring to ensure proper absorption, repeat until completely wetted. |
|
 |
 |
|
Step 1: Quarter-fold Wiper after wetting with DI Water. For use with IPA, quarter-fold prior to wetting. |
Step 2: With all four fingers on top and the thumb on the underside of the Wiper, pull it across the surface of the tool using very light pressure. |
