Congratulations on that!
Did you manage to the reflow at home, how did you do that?
I used and electric frying pan that I bought at a junk shop for 7 dollars.
I haven't tried this on FRP4.
Just start low at approx 150C for 90 seconds to warm things up. This apparently is an important step.
Then turn up to about 300 till everything melts properly then take out of the frying pan, becuase the frying pan takes a too long to cool. Dont stress too much about the high temperature as the chips can normally take it.
Use a eutectic solder paste, not 60/40 pb/sn as this will give a greater cooling window for bad joints. eg If it gets bumped while the joint is in the quasi state between liquid and solid it can form a bad joint. This could happen while you take it out. 60/40 is in this state for 3 degrees but 63/37 is eutectic and is only in this state for 0.1 degrees apparently. solder paste is generally in more complex combinations.
I tried making my own toaster oven (still incomplete) but the frypan works particularly well with the mcpcbs so i didn't need it.
