Its a neat thing to see for the first time - the flux turns to soap bubbles! When all the bubbles are gone, the flux has all been removed and you dry the boards. We use a modified dishwasher to do ours . . . The sticker is there so that the soapy water does not get inside the buzzer. dwayne -- Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax Celebrating 18 years of Engineering Innovation (1984 - 2002) .-. .-. .-. .-. .-. .-. .-. .-. .-. .- `-' `-' `-' `-' `-' `-' `-' `-' `-' Do NOT send unsolicited commercial email to this email address.
