If I get 10 boards on my board order, I need 4 for 100W 1400ma and 3 for 50W 700ma. 
I've been reading up on SMD soldering and bought some of the paste you linked me to. Getting excited!!---Rick |
Cool Rick!
Once you've learned how to solder SMD, You'll prefer it over "through hole" any day. Since your PcB doesn't have the current setting jumpers it actually makes it easier to predict and fine tune your desired current levels. I've got an Excel spreadsheet from Allegro that will make choosing the Rsense resistor values easy for you. I found that, due to the small amount of resistance added by the jumpers in my design, my expected current outputs were always lower than expected. I had to skew all my resistor's values lower to compensate.
The spreadsheet is attached.
