Due to the strict requirements of LCD repair our equipment
is situated in a cleanroom environment to produce the highest levels of
quality. The ISO 5 inner room facilitates laminating, delaminating, tacking
and bonding. Backlight replacement, preparation and functional testing
take place in the ISO 8 outer cleanroom. |

Summary of FS 209E and ISO 14644-1/2
The cleanliness classification levels defined by FS209E and ISO 14644-1
are approximately equal, except the new ISO standard uses new class
designations, a metric measure of air volume and adds three additional
classes - two cleaner than Class 10 and one beyond than Class 100,000.
The second new ISO standard, ISO 14644-2, gives requirements for monitoring
a cleanroom or clean zone to provide evidence of its continued compliance
with ISO 14644-1. |
