We have recently purchased a Malcom PC-1TL viscometer with VS-3 measurement head. We plan on using this device to measure paste viscosity. I am looking for information on how the Malcom system compares to the Brookfield spindle system. I understand that the readings are not directly comparable. Technical publications and other references would be appreciated. I have ordered a paper from EMPF (PET0001-Implementing SPC on Solder Paste), but haven't received this yet. I performed a calibration check per the Malcom documentation and found that the recommended measurement period wouldn't give the proper results. The equipment was new at the time. I found that I needed to increase the measurement period to get the specified calibration sample viscosity. Is this normal? BTW- thanks for putting up with my automatic replies over the last weekend. This won't happen again. Rick Vernon, QA Engineer Phoenix International Corp. (701)282-9364
