Reckless that's easy : Tabletop units are a joke, you could just as well go build one yourself with a toaster oven and a controller, the results won't be great but at least you won't have spent $5k on one with a ssnazzy screen. "Hulking Units" - wel

We are using ECD OvenRIDER to validate our reflow ovens on a weekly basis to have the data to show our customers that the board we ran 3 months ago saw the same oven condition as the one ran yesterday. Cp/ Cpk is calculated by ECD using a manually i
