Austin American: Combination Cleaner & Tester
Self-contained PC board cleaning system..
Austin, TX — Austin American Technology Corp. has developed what it calls the world's first combination cleaner and cleanliness tester for circuit assemblies. The Mega Ion is a portable closed-loop single-board cleaner with ROSE (resistivity of solvent extract) cleanliness verification testing built-in.

Unlike other cleaners that simply check the rinse water, the Mega ION actually completes the cleaning operation with an industry standard ROSE test giving the actual micrograms NaCl eq/per square inch (of PCB surface) and a real pass or fail. It is designed to provide verifiable cleaning support locally to manufacturing operations such as touch-up, add-ons, ECOs, product development, and pre-conformal coating cleaning.

The cleaning system can use a selection of solvents ranging from traditional water and IPA blends to proprietary solvent blends. The solvent selection can be matched to clean the residues that need to be cleaned.

The system cleans flux residues with a single solvent, or solvent blends, spray under immersion, cleaning process that can be followed with an automatic measurement of the ionic cleanliness of the circuit board. A built-in dryer completes the cleaning/testing cycle.

The cleaning system is sealed and therefore uses a minimum amount of solvent (<100gals/year). This is accomplished in a closed cleaning operation were solvents are used and stored in closed stainless steel tanks located inside the machine. The solvent is automatically renewed with built in mixed bed ion exchange resin tank that removes anionic and cationic soils from the cleaning solvent.

Current testers are limited due to compatibility problems with plastic tanks and with the older style ion exchange resins used. The new Mega ion exchange resins work well with water and IPA and are uniquely compatible with many other organic solvents unlike water resins. All tanks are made of stainless steel.

The system has a small footprint (30 x 36-in.) is built in a stainless steel floor-standing mobile cabinet (with lockable casters), requires 220VAC, air/nitrogen supply, and a vent. Noise levels are stated at less than 80dB. The system is UL Compliant — UL 1950 (standard), CE and CSA Certifiable and is designed to NFPA 79. The body is constructed from stainless steel. Seal and gaskets come in Teflon, EDPM or buna-N. The cleaner is equipped with various cleaning tank sizes up to 10 gallons (37.854 liters) and also has a sealed stainless 20 gallon (75.708 liter) holding tank.
