We recently trialled a range of different solder pastes. Some just did not have the "green strength" to hold the components when placed by the higher speed machines. I'd never seen this before and spent a day and a half checking all the things everyo

What we did: *Slump-dot diameter and height as a function of time *Print Speed-Vary speed, measure slump and missing/defects *Green Strength-We quantifiably measured tack vs time and we placed components and measure skew by SVS *Cure profile sensitiv
