We have been encountering diminishing ball shear readings these past few weeks, despite the fact that we did not change any ball shear tester parameter. Our reflow parameters are also within spec limits. ( 210-220 deg C max temp. and 40-60 sec dwell

| 5 micrograms per sq. cm. is actually not too clean. The maximum military allowed post-clean, on-board contamination is 5.7 micrograms of NaCl /cm squared (when using the Zero-Ion brand ionic contamination tester). | We are use to seeing cleanlines
