We are currently using Alpha 564 for cleaning in our clean room for batch cleaning. Our health and safety people would like to reomve this material from the building and use another cleaning in its place. The have come up with some sample material (Leniun ES) it is an azeotrope of isopropyl alcohol & N-propyl bromine. It seems to work well and we have had little problems with it. But would just like to check with everyone else and see it anyone uses it, tried it and what you have to say about it. thanks ****************************** James TerVeen Manufacturing Engineering Supervisor L-3 Communications Narda Microwave - East 435 Moreland Road Hauppauge, NY 11788 516-231-1700 ext. 391 Fax. 516-231-1480 E-Mail [log in to unmask] ****************************** ################################################################ TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TechNet <your full name> To unsubscribe: SIGNOFF TechNet ################################################################ Please visit IPC web site (http://jefry.ipc.org/forum.htm) for additional information.
