Graphite Felt Basics - Manufacture Process

Carbon based insulation is made from organic fiber precursor through needling process, carbonized and graphitized (sometimes purified). It is to be used in vacuum or international gas protected environment.

Ultra Clean PFA Tube test result @ sulfuric acid

Cobetter Tube 12 ~24 hours <10ea
POR Tube 168 hours <10ea

Research results :

  • IPA Valve testing data (monitor 19nm) by cobetter: IPA flush 6hr particle 2ea, 4ea, Oea.
  • 2. The LPC test is OK, but it still requires a long time for rinsing when delivered to the Fab.
  • 3. Valve Pre Clean, the flushing time was reduced by 30 days.
