What's the best company for low volume, quick turn around PCB assembly? Why do you choose their service over others? What's the cost ballpark for 10 3"x3" boards assembled?

You're correct. You should expect to see an intermetallic layer in a proper solder connection. Try leaving the component at temperature for a longer period. Growth of intermetallic compounds on Cu surfaces [Klein Wassink]: d = 10^3(exp(-5*10^3/T)t^1

Couple notes here: 1. Try to shoot for 250C peak temperature. 2. Use all your 10 zones in profiling for more accurate profile. You should not reach your highest temp in zone8. Try to reach it in zone 10. 3. Go quicker. Your profile might be too long
