OM-610-1002-1 Operator’s Manual Rev 37 SECTION 6 MAINTENANCE PARYLENE DEPOSIT REMOVAL The nature of the Parylene coating process necessitates the periodic removal of the Parylene that is deposited on the interior surfaces of the coating chamber and related components. 6.1.1 Applying Release Agent To aid the removal of the deposited film it is imperative that a release agent be applied to all surfaces that will be coated and subsequently stripped.
Rev 37 Operator’s Manual OM-610-1002-1 6.1.3 Cold Trap Probe (Thimble) To achieve the coldest possible cold trap probe surfaces and to preclude the separation of trapped deposits, remove and clean the cold trap probe promptly after each run. Set the probe in the holder provided on the machine.
OM-610-1002-1 Operator’s Manual Rev 37 NOTE: The system base pressure should be regularly monitored. Increases not attributed to vacuum leaks or outgassing usually indicate a deterioration of the pumping system. Deterioration is usually due to the passage of process by-products that are not effectively trapped by the cold trap probe. In some instances, lower cold trap temperatures will alleviate this condition.
Rev 37 Operator’s Manual OM-610-1002-1 6.2.3 Vacuum Hose Over time, the vacuum hose tubing will acquire a compression set. If the system develops a leak associated with this tubing, we recommend that the tubing be replaced. 6.2.4 Rotary Feed-Thru Maintenance Refer to Figure 6-1.
