Austin American Technology's Mega™ cleaners are designed for high reliability, environmentally-friendly, solvent-based cleaning applications. These closed-loop, solvent regenerative systems feature quantitative ionic contamination detection and statistical process control capability.

Wash and rinse cycles incorporate a highly effective spray underimmersion process with strategically located venturi nozzles for maximum cleaning efficiency. Agitation can be controlled to handle sensitive wire-bonded substrates or difficult to clean, tightly-spaced flip chip technology. Ultrasonics are available for additional cleaning power.

Safety is designed into the Mega series. The process chamber is always empty when not in use and must be closed and latched before the cleaning cycle begins. Solvent replenishment is automated so the operator is never in contact with wash fluid during normal operation. At the end of the cleaning cycle, the process tank drains into an integral holding tank at a controlled rate to minimize dragout. At the end of the dry cycle, the process chamber is clean, dry and free of solvent.

The entire cleaning process (wash, rinse, dry) typically takes only 10-20 minutes. For maximum drying, the heated Vortex option is available.

Closed Loop Batch Cleaning of Flux to J-STD-001
"The purpose of this test is to determine the best method of meeting J-STD-001 cleaning requirements in an AAT closed loop batch cleaning system ...

The two boards soldered with water soluble organic acid were cleaned in de-ionized (DI) water at temperatures of 120F to 130F respectively. Four of the six RMA fluxed samples were cleaned in 100% MegaSolv JB simulating cleaning in an AAT Mega II spray-under-immersion closed loop cleaner varying time and temperature. The last two samples with RMA flux were cleaned using commercial aqueous cleaning agents in an AAT AB-1500 spray-in-air batch cleaner as defined in Table 1. The AquaBatch-1500 has been replaced by the new AquaTherm series."
