Akrion has implemented a new policy for ordering replacement computers for all Akrion wet stations. The only computer components that can be individually replaced in the field are I/O cards. If the problem can be isolated to an I/O card, order the appropriate card and replace it. When computer based issues are not the result of failed I/O cards, the entire computer MUST be replaced.

As part of Akrion’s continuous improvement program (CIP), Akrion is introducing an upgraded capacitive sensor for the sensing of the liquid level in the LuCID dryer process tank. This upgraded sensor version is equipped with a moisture-compensating feature, which enhances and improves the sensor functionality and reliability. Therefore the use of the “sensor pads” (gasket) is no longer required.

Not reporting missed dropoff error for cassette style queues. This problem only exists on benches that are configured to process two cassette lots. The failure of the system to recognize a missing cassette at the queue can cause wafer breakage since if the cassette is not on the queue it must be somewhere else within the station.

Akrion sensor (202908) used for product detection on both GAMA and Rearmount wet station robots use a 4 amp, 24VDC relay (RLY1B0065) in their circuit. This relay had a specific pin configuration and associated schematic printed on its side. This pin configuration and schematic were also included on drawings 202879 and 202880 issued with the kits for upgrading from older SICK sensors to the newer 202908 sensors. At some unknown time, the relay vendor began supplying a new relay for this associated part number with a different pin configuration. These changes have not been incorporated into the drawings and have caused confusion in the field.

DMC2 servo drives are factory programmed for use with specific servo motor types from different manufacturer sources. Commonly named M406D or S32, the different motor types require specific DMC2 configuration programming files to match the motor type to the servo drive setup. Mixing the wrong motor types with the wrong DMC2 program type will result in undesirable robot operation and failures.

Loose hex-lug power bus connections on the main power feed wires (L1, L2, and L3) and input/output lugged connections of both the main circuit breaker CB1 and main contactor K100, have been isolated as sources for voltage anomalies which have led to component failures in the main power branch circuits.

Drawings are no longer produced or maintained for computer card parts identification or board placement. Many benches supplied with NT computers were issued Blueprints manuals having an outdated reference drawing such as COM009785 to show card placement. The materials list is not the BOM of the fully loaded NT computer. Ordering parts from any document other than the latest fully loaded computer BOM specific to a bench, may lead to the inaccurate ordering and supply of parts.

Mini environments (ME) equipped with a door latch (interlock) feature may not pop the door open/ajar when the door request button is pressed. If the door is not manually opened in several seconds, the door request open time expires, and problems can occur. For example, the wafer transfer unit may lock up and not load/unload product, or it may move to a position that does not allow the equipment operator to access the load/unload area.

The size of the buss wire has increased from 10 gauge to 8 gauge for both the 8 kW (207433-001) and 4.5 kW (207433-002) heaters. Plenum feed through holes/fittings sized for 10 gauge wire are too small for 8 gauge power wires.

Akrion now recommends a Clean Point Unit inlet filter element pore size of .01um and a CPU outlet filter element pore size of .04um. This larger to smaller pore size in the liquid flow path will improve the filtration efficiency that is lacking in the original OEM design. In addition, the .04um outlet filter has been upgraded. The Akrion part number of the .04um filter is 215143-001 (rev B).
