In a low-volume application an ordinary home dishwasher will do fine,
PROVIDED you use deionized water (not "soft" water) and a cleaner designed specifically for the job. In my previous life I tested many cleaners and the one which did the best job and left the least residue was Armakleen E-2001 made by Arm and Hammer. A 55 gallon drum was about $2k a few years ago. Good stuff, but I do miss Freon. For what it's worth, National Semiconductor's resident wizard Bob Pease used to clean circuit boards using an ordinary dishwasher and "a standard charge of Calgonite". If I recall correctly, he suggested taking the board out after the rinse cycle, doing a final rinse with distilled or deionized water and then shaking the remaining water off of the board prior to air-drying. He reported that this method would get the cross-board leakage currents for sensitive high-impedance circuitry down below what he was able to achieve with organic-solvent washes. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
