Stripping Costs From Photoresist Processing

ed into quick-dump exchanges. This meant that the bath sol- vent chemistry was circulated in such a way that it flowed over the screens, removing any large clusters of resist before they could become to- tally solubilized and deplete the ef- fectiveness of the bath solvent. Re- moval of resist clusters also meant that they were no longer a threat to bath filtration or circulation. The next step was to build a test module, which included a bath with a single series of screens, a reservoir, basic control system, and a pump. “Once completed, the customer came back out and we did testing again,” Zrno says. “After successful testing of the module, JST designed and built a fully-automated produc- tion tool with a 6-gallon bath and 20- gallon reservoir. We also added other proprietary components that enabled the tool to meet the customer’s needs.” The customer ordered two of the new production tools in order to run parallel processes and meet through- put requirements.
A Combination of Savings
As anticipated, this new, auto- mated resist-stripping tool reduced chemical usage, and the series of screens prevented the recirculating bath chemistry from plugging up the filters.
Chemical usage dropped by two-thirds at the customer’s resist stripping stations, mainly due to the increased bath life. Also significant was the reduction of downtime for changing baths, which normally took 30 to 60 minutes. That time was re- duced by two-thirds as well, as was the associated downtime to drain and recharge bath solutions.
The new resist stripping station includes a menu of built-in settings, which were tested and installed at the JST factory lab. This menu makes it unnecessary for users to go to another facility to establish new settings, a process that could increase production

back into their pockets,” Buck says. “It’s truly a ‘cradle-to-grave’ solution for electronics manufacturers. As partners, we can offer these products and services as seamlessly as if we were one company. This relationship makes both companies stronger and more competitive in the market- place.”
“Amerway is a small, family- owned business with the technology and capabilities of much larger cor- porations,” Buck concludes. “We of- fer a free solder pot analysis, high- purity material, shorter industry lead times, a certificate of analysis, and certificate of conformance with every order upon request. Buying from Amerway means buying direct- ly from the manufacturer.” Contact: Amerway, Inc., 3701 Beale Avenue, Altoona, PA 16601 814-944-0200

downtime by up to several days. According to Zrno, it makes a lot of sense to periodically review produc- tion systems, such as wet processing equipment, particularly when produc- tion procedures change. In many cas- es, making minor modifications to ex- isting equipment, whether standard or custom, can help companies save significantly.
