Recently we've been on a big push to get current customers to change 
drawings that required solder mask over reflowed tin lead smobc. The 
reasons that we give them are 1. fits our process (90-95% of all 
boards produced are currently smobc) 2. the EPA issues with the use 
of tin-lead. 3. te reliability gained when going to smobc.
	The question which has been posed is, does going to smobc somehow 
change the current capacities, or other electrical and or mechanical 
properties of the boards. What, if any are the disadvantages of smobc 
vs reflow? Can anyone comment?

Thank You,
