Shirley:I'm guessing you are refering to Kester 5631-C2.We ran side 
by side testing with the Kester,Enthone 106A and a couple of other OSP's.The	
 Kester and Enthone perfomance was very similar (i.e.good)thru OUR assembly  
 processes.I can't supply you with the written report but I can discuss the	
 testing for both bare board fabrication and assembly to some extent over the 
 phone.
