Sorry folks - left out some pertinent information with my last question. The control boards all came out fine - values exceeding 1E+12. We did do all the SIR tests simultaneously, but we were able to differentiate between the four fluxes that we tested, thus we have confidence that no cross contamination occurred. We would be considered Class 2 - 'Dedicated Service Electronic Products' in IPC classification. Thanks again, Amanda Amanda Mountain Process Engineering Leitch Technology International Inc.
